There is no lack of comment, opinion and overblown diatribe regarding the upcoming potential “fiscal cliff.” The politicos love to be able to scare people by predicting economic catastrophe if certain members of either party don’t come to a consensus on how to resolve this problem. The interesting thing is that even if the parties don’t agree something will happen without their involvement or decision. And, chances are that all this partisan posturing will be replaced with a compromise that will give credit to both parties while making the right decision for the American public. Disaster averted!

In the field of air filtration there are often two distinct approaches to resolving the same problem. And, like the political parties, one is often more correct than the other. More over, the right decision will have a very positive effect over a very long period of time and for a large number of individuals.

The removal of airborne particles from indoor air environments has always employed some type of mechanical filter. Cloth medias, fiberglass filters, cotton fiber filters and the man made medias ( including HEPA ) have been around for over 70 years. Mechanical filters are simple in nature. They capture the airborne particles that are drawn through them ( usually by a fan or air moving device) and the larger particles get caught in the media fibers while some of the tiny particles pass through. Over time as the filter media loads up, or gets dirtier, even most of the smaller particles are caught in the filter. In the case of HEPA filters, sub-micron particles are captured at efficiencies approaching 99.99% at less than 0.3 microns in size.

One other type of filtration device was also developed and used in the early 50’s and a variation of that technology is still use today. The electronic air cleaner was a simple device that used positive/negative charges to attract particles as they passed through a charged wire grid. The earlier versions were not very effective except for capturing very large particles. The newer versions are slightly better but this technology is really not appropriate for any applications except general duty residential.

In the 70’s another style of air filtration device hit the market. However, these devices were referred to as air purifiers and not air filters. These consisted of ozone generators and ionizers. They did not use any type of media and were touted as being able to purify the air in your home or office and no filters needed to be changed. Simply wipe the attraction plates or replace a small component part once in a while and you had all the clean air you could ask for. Unless you really wanted it to actually work at removing airborne particles.

Air purifiers are simply not capable of eliminating the harmful, sub-micron, airborne particles and allergens in the air. This is the reason that hospitals, laboratories, chip manufacturers, optics companies, the CDC, etc. etc. do not use air purifiers for any application. They rely only on mechanical filters such as HEPA filters. But, the discussion continues to rage on and there are proponents on both sides of the equation.

The acronym HEPA stands for “High Efficiency Particulate Absolute” filter. The word absolute means just that. A HEPA filter by standards means it will capture, initially, 99.97% of all particles 0.3 microns in diameter or larger. This means if you had 10,000 particles in that size range and put them through the HEPA filter only 3 are allowed to pass through the media. There are scanned HEPA filters which have a minimum efficiency of 99.99% at 0.3 microns, ULPA filters with minimum efficiency of 99.9995% at 0.12 microns and SULPA filters with minimum efficiency of 99.99999% at 0.12 microns. In every case the overall efficiency of the filters is directly proportional to how the filter in sealed, or contained in the holding frame or air filtration device.

There are a number of small, portable style HEPA filtration systems sold on the market today. The majority of them are designed for residential applications; specifically bedrooms and small living areas. These systems have very small fans and can only move about 50 to 200 CFM of filtered air and have HEPA filters that are not necessarily sealed tightly in their housings. Then there are fewer than 5 portable type HEPA units that are designed to be used in the commercial markets where optimum performance is required. When we get to the larger, stand-alone HEPA filtration systems, those that can move from 100 to 2,000 CFM of filtered air, there are only two companies in that arena.

HEPA filters are expensive. They requires very special equipment to manufacture them and highly sophisticated, expensive test equipment to certify them and ensure they meet all the regulations and standards that allow them to be certified as HEPA filters. They are usually framed in aluminum or steel and have a gasket on one side to allow for compression sealing in their prospective housings. Unless the HEPA filter is completely sealed, air will by-pass around the filter and render the HEPA filter useless.

Companies and individuals purchase HEPA filtration systems to perform a certain function; removal of harmful airborne sub-micron particulate. The airborne particles may be allergens, pathogens, dust and dirt particles or particles from a manufacturing operation. In almost every case, the performance of the equipment is tantamount to the price of the systems. Since the lack of performance is directly proportional to the overall efficiency of the specific operation, the inability of the HEPA systems to perform can cost hundreds of times more than the equipment itself.

Pure Air Systems has been manufacturing commercial grade, certified HEPA based air filtration systems since 1985 and its systems are considered one of the premier units on the market today. The fact that PAS has been in operation for over 27 years is a testament to their ability to meet or exceed the expectations of their customers. The medical, commercial, institutional, environmental, military and industrial markets all look to PAS to help them solve their critical airborne particulate problems. Performance is their primary concern.

Taking the Confusion Out of Air Filter Efficiency or What Do They Really Mean When They Say That?

I will try to keep this simple and short so as not to add to some of the confusion over air filter efficiencies. First, I would like to point out that any company that sells an air filter that states an efficiency rating without basing it on a particle size is providing you with basically useless information. For example: an air filter that has a statement reading “this filter will remove up to 95% of all airborne contaminants in your home or office”, doesn’t really tell you anything. Since most of the respirable particles that actually are harmful are usually less than 2 microns in size, don’t you think it would be important to tell you what size particles they actually remove from the air? So, let’s look at this statement again. “95% of all airborne contaminants” sounds pretty good, doesn’t it? Our HEPA air filters remove 99.97% of all airborne contaminants at 0.3 microns and smaller. At first glance these two air filters look similar in capability. But the first air filter provides no particle size range or efficiency based on particle size.

Recently the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) and the air filter industry have come up with a standardized rating system, based on the European concept, of a MERV rating for each type of air filter. This numbering system makes it easier to evaluate and compare mechanical air filters and will hopefully eliminate some of the confusion regarding the overall effectiveness of any type of a mechanical air filter on removing airborne particulates, especially those that are less than 2 microns in size.

Bbelow you will see the new MERV ratings. This MERV rating chart has the MERV ratings, 1-16 on the left hand column and then there are five other columns showing the average efficiency in microns, average arrestance and the final resistance as measured in inches of water. Most companies that make air filters are now using this MERV rating, so you will see a MERV number on the air filter and perhaps some rated efficiency.

Comparing Various Air Filters to MERV Ratings

• Throw-Away Fiberglass Media MERV 1 -MERV 4
• Pleated Media Air Filters 30% ASHRAE MERV 10 – MERV 11
• Pleated Media Air Filters 65% ASHRAE MERV 13 *
• (* 65% ASHRAE is about 20% effective on less than 1 micron particles)
• Pleated Media Air Filters 95% ASHRAE MERV 14

Some of the man-made synthetic media like that used in the 3M Filtrete air filters may be rated MERV 15. However, they hold very little dust and load up quickly and have a relatively high-pressure drop (static pressure) and can affect the performance of the heating / cooling system.

MERV Ratings Comparison Chart

RESPA Air Filter Efficiency – MERV Rating Chart

IMPORTANT NOTES:It is important that you select the RESPA Filter that best fits your application.MERV is an acronym for “Minimum Efficiency Reporting Value”. The MERV rating on an air filter describes its efficiency as a means of reducing the level of 3 to 10 micron-sized particles in air which passes through the filter. Higher “MERV” means higher filter efficiency. The purpose of the MERV standard is to permit an “apples to apples” comparison of the filtering efficiency of various air filters. <Read more about MERV and HEPA filter ratings>HEPA air filters are not MERV rated as they exceed the ASHRAE test protocol 52.2 used in determining the MERV ratings. In fact, HEPA air filters are the ONLY mechanical air filters that are tested and certified to meet a specific efficiency at a specific particle size. All HEPA air filters must meet a minimum efficiency of 99.97% at 0.3 microns. <Read more about MERV and HEPA filter ratings> Comparison of EU Standards to ASHRAE 52.1, 52.2 (MERV Ratings) Considerable differences exist between filter ratings in North America and Europe. This article helps the reader to understand the differences between ASHREA and EU standards for Filtration. Additional light is shed on the significant differences in the HEPA filtration standards between the US Government and the European standards. This article will help the reader to appreciate the MERV 16 filtration offered by Sy-Klone International. <Read more about European filter standards and how they compare to MERV ratings> >> Go to RESPA-SD Product Information >> Go to RESPA-SDX Product Information

This is an important chart to keep for future reference in determining the best filter style and type for your specific application. Understand that the higher the MERV rating the greater the resistance or static pressure will be across the filter media. For most HVAC furnace filter applications a MERV 8 and lower since these filters will allow for lower resistance with good filtration of larger particles.  Using the 3M type filtrete filter not recommended for most general duty residential heating/cooling systems. These filters load up very quickly and will actually reduce the HVAC fan performance requiring longer cycles to both heat and cool your home.

Pure Air Systems has been manufacturing commercial grade HEPA and Carbon based air filtration systems since 1985. These units are designed to be used either attached to existing ducted HVAC systems or as stand-alone units. The ability to use a true HEPA filter system ( which would have a MERV rating of 18 if they rated them) in a residential application makes these unit unique in the filter market.

When discussing the size or amount of CFM (cubic feet per minute) of air flow required from one of our HEPA systems to effectively remove or reduce the levels of airborne particulate it is good to know a few basic rules of thumb when determining the right size, quantity and location of the HEPA systems. The math is really simple.

You need to determine the area of the room in cubic feet, so you first need to  measure the length and width of the room. Let’s say it is 15 feet long and 20 feet wide. Multiply 15 x 20 and you get 300 square feet. Now multiply that number ( 300 ) times the height of the room. We will make in 1o feet high. So you multiply 10 x 300 and you get 3,000 cubic feet. This is all it takes to determine the area of the room.

Depending upon the type of application and particulate loading and size range of the airborne particulate you will require a certain number of air changes per hour to accomplish your goal of air contaminant removal. In the case of a clean room type requirement, those are usually designated by Class. Such as Class 100,000, 10,000, 100, 10 and 1. These are rated as .3 microns per cubic foot. As an example a class 10,000 clean room environment would need to meet the criteria of nothing over 10,000 particles per cubic foot at .3 microns or smaller.  Considering the room without filtration could easily register 400,000 particles plus per cubic foot at .3 microns, this reduction level requirement is fairly significant.

Since not all applications require a clean room environment, however, even for residential and light commercial applications, a large reduction of particulates in the air is still necessary. So understanding some simple rules of thumb regarding air exchange rates is necessary. So now that you know the area of the room you need to figure out how many air changes per hour ( how many time you want all the air in the room to be cleaned) and this will bring you to the size  requirement of the air filtration system.

Effective removal of airborne particles is dependent upon two factors. A room in stasis or an active room. When a room is unoccupied or no equipment is running in a room the levels of particulate stay fairly constant. As an example we will take our 3,000 cubic foot room and say it is a small health clinic. During its normal daily operation it will most likely be occupied all of the time. People, clothing, equipment all generate sub-micron sized particles. If the room was seldom occupied probably  2 to 3 air changes per hour would suffice and maintain a relatively clean environment. Three air changes per hour would require a system that produces 150 CFM  or 9,000 cubic feet per hour. For a medical clinic that is occupied a minimum of 10 air changes per hour would a filtration system that produces 30,000 cubic feet per hour or 500 CFM.

By using these simple math formulas you can determine the amount of HEPA filtered air required for any size room. Remember, the higher the exchange rate the cleaner the air. Medical and high-tech manufacturing requirements will require higher exchange rates. Residential and light commercial or institutional may be lower.

“Here I come to save the day….that means that Mighty Mouse is on his way. Yes sir when there is a wrong to right, Mighty Mouse will join the fight….” And so the song goes. If you are old enough to remember that cartoon you know that Mighty Mouse became a metaphor for the ability of small people to make big things happen.

There are a number of things today that we might link to the ‘small but mighty” phrase; cell phones come to mind. Today’s cell phone is really a miniature computer. Talking on it is only one of its uses. You can get email, send texts, use any of your social media apps, skype, tango, face-time, get directions, take photos or videos,  make reservations, purchase products and the list goes one. All from one small device that sits in the palm of your hand.

Pure Air Systems has been making HEPA and Carbon based fan powered air filtration systems for the residential, commercial, institutional and industrial markets for over 26 years. Their product line includes systems with air flow capacities from as low a 30 CFM up to 2000 CFM. The size of the larger units range from 12′ square by 36″ tall to 48″ square by 55″ tall. However, the new kid on the block is just 13″ square by 21″ long.

The new HPS 350 and 500 series portable units are two of the most powerful portable HEPA filter systems on the market today. Using commercial grade, scanned 99.99% at 0.3 microns and smaller and a combination polyester carbon media prefilter. The unit is made of 20 gauge powder coated steel and weighs only 30 lbs. The air flows range 150 CFM to 500 CFM using a four speed fan control switch.    These air flow rates are higher than any other portable of a similar size anywhere on the planet and the powerful EBM blower/motor assembly is rugged, durable and powerful enough to pull the air across the HEPA to provide the designed CFM speeds.

The HPS units, like their big brothers, are designed to be used in either a partial by-pass concept when being attached to an existing HVAC return air duct system or as stand-alone units. Most often they are used as portable room filtration systems for individuals with allergies, asthma or other respiratory dysfunctions.

For commercial applications the HPS units are perfectly suited to cleaning the air in small clinics, medical and chemical laboratories, patient care rooms, class 10,000 clean room environments and building offices.  The units can be used to pressurize a small room or make it negative depending upon the specific requirement. The ability to vary the speed of the powerful blower/motor allows for the use of the HPS units in bedrooms and areas of the home where low noise levels are required but filtration is still needed.

The HPS series by Pure Air Systems. A small but mighty unit that really is designed to save the day.

Most HVAC contractors concentrate on selling, installing and maintaining their line(s) of HVAC systems…be it residential or commercial. For most HVAC contractors the larger portion of their profits come from servicing the heating/cooling units and not the sale of the systems. This is especially true for contractors who do mostly new construction. As a result, HVAC contractors rely heavily on maintenance and accessories to boost their bottom line.

Since all HVAC contractors install some type of air filter or air filtration device along with the heating/cooling system, this product also provides a great addition to their line up as it needs to be replaced and/or cleaned on a regular basis. Filtration is a very important part of the total HVAC system. Without any filtration the dirt and dust from both inside and outside the building or structure would eventually clog up the cooling coils, fan, motor and other air flow sensitive equipment and stop the system from operating. Of course, the other main reason is to keep the indoor environment as clean and healthy as possible.

Pure Air Systems has been manufacturing HEPA and Carbon based fan powered, commercial grade air filtration systems since 1985. These systems are all designed to be either attached to an existing HVAC return air duct system or used as stand alone units. Since it inception, PAS has installed well over 10,000 of its model 600HS unit in homes across the US and Canada. Today, many of the larger homes and offices now use the PAS models 1200HS and 2000HS where larger HVAC systems are employed.

The PAS systems are recognized as providing the best air filtration in homes, offices and commercial operations than any other filtration system on the market today. For HVAC contractors, adding the PAS product line to their product line up. The overall flexibility of these units to be installed with almost any HVAC package in any building structure provides a great advantage for contractors looking for a multi-purpose air filtration system. In addition, these units can all be used to not only filter all the air in the specific indoor environment but also introduce small amounts of outside, filtered fresh air when the application calls for it.

One of the major advantages for HVAC contractors to offer the PAS units is the continued loyalty of their customers to the systems. Once the HEPA units are installed, the vast majority of the customers fall in love with the systems. Fewer allergies, colds and less dusting are primary benefits of the systems. This means the customers want to have the same contractor that installed them come back and service them along with their HVAC system. Over time PAS has found that many end users become more loyal to their air filtration systems than their heating/cooling units.

The word wired has a number of meanings. It can be used to describe how one feels after drinking four cups of coffee in an hour or after eating two or three Twinkies for lunch ( not recommended). Sometimes wired is used as a prefix term such as “that guy or girl was really wired in.”  Meaning tuned in or right on really understands the message. It is also the name of a very popular “avant garde” magazine that describes the future of technology.  Wired is a positive word and not often used to describe a company, but we will do that now.

Pure Air Systems started making HEPA and Carbon based air filtration systems in 1985. They philosophy of the company was then and still is today, to make the best commercial grade, certified HEPA systems on the market and incorporate only the best, most reliable components in the fabrication and assembly of the systems.

Early on its development, PAS was wired into the whole issue of what was then called “Environmental Illness,” or EI. Back in the early 80’s most building materials for homes, offices and schools were still being made with formaldehyde laced glues and substrates along with very limited fresh air ventilation for their HVAC systems. PAS was very involved with a number of organizations that were very vocal about the continuing health problems associated with short term and long term exposure to airborne gases and particulates.

Because HEPA filters, at that time, were still primarily used only in the electronics and hospital markets, the average  homeowner had little knowledge of the overall capabilities of what HEPA filters could do. And, PAS was very wired in to the capabilities of using granular activated carbon and blended medias for the reduction and removal gaseous pollutants. PAS experimented with a number of suppliers of carbon to find the best carbon product that would both work well in their systems as well as provide the needed performance demanded by their customers.

Since the major distribution for the PAS systems early on was using HVAC contractors, Pure Air Systems was wired in to the issues with the lack of fresh air in most building structures and the direct relationship between this issue and environmental illness. As a result of these business relationships PAS was able to develop a concept using its wide range of HEPA based air filtration systems to allow for both total filtration of the indoor environment as well as the introduction of fresh, filtered outside air. This partial by-pass concept has proven to be one of the most successful methods of providing an environmentally safe and healthy indoor environment in homes, offices, schools, hospitals and small industrial facilities.

Change for the sake of change often is not a good thing….unless the change is really needed. For the most part, people resist change even if they know taking a step in a different direction may actually be good for them. Studies have shown that changing someone’s belief in any subject matter is extremely difficult, even if you can show them actual proof their beliefs are not correct.

Getting people to accept that “process interrupt” is difficult. Getting someone to change their habits is usually most effective when the change affects their health. One of the areas associated with healthy living is the use of or the addition of air filters or air filtration systems for those individuals who suffer from severe allergies or other airborne particle induced respiratory dysfunctions.

Pure Air Systems has been making HEPA and Carbon based air filtration systems since 1985. They also offer a complete line of dual-layer polyester ring panel filters that can be used individually from the HEPA systems. For most home owners with allergies, the ability to maintain a high level of clean air is very important. They know that airborne dust and allergens ( including pollen, ragweed, grasses, mold, etc.) are not always just outside the home environment. Much of this material is brought into the living spaces and is distributed through out the house via the heating/cooling system.

Removing the smaller airborne particles from the air in your home is most often done by placing a filter in the main return air duct at the junction of the heating/cooling air handler section. This is the most common location for filters. It is important to remember that filtration only occurs when the air handler fan is running so it is better to have the fan switch in the on position on the thermostat all the time so filtration takes place even when heating or cooling of the environment is not required.

Selecting the correct air filter is important. There are many styles and types but you want one that has the greatest efficiency for removing small, micron sized particles without creating too much static pressure resistance for the air handler. Pure Air Systems offers a wide range of sizes of their ring panel filters. These filters have a wire frame which is wrapped with the polyester media allowing for a very tight seal in the return air duct filter slot. This means no particulate bypass of the filter and total capture of all the airborne contaminants.

Most importantly, the filter will need to be changed on a regular basis. Whether you use the PAS filters or another brand, changing the filters at least once every three months or more often is necessary. The filters are constantly loading up with dirt and dust and as they load up the pressure drop across the filter increases and this can actually reduce the air flow through the air handler. Then there is less air being pulled through the entire system and cooling and heating efficiency is dramatically reduced. As is the ability to capture the airborne particles.

Make a rule that every quarter you change the air filter in your HVAC system. Both you and your air handler will breathe better for it.

For most children the ability to explore their surroundings  is usually conditional to the restraints put on by  their parents…more often than not, their Mother.  Most children have more energy than they know what to do with and running is one way of using that energy. “Don’t run,” is the most often constraint placed on kids. A large number of accidents occur when children run with abandon. It is, however, more challenging when children run with something sharp in their hands….like scissors.

Telling someone not to do something because it may cause them harm often falls on deaf ears until that person has an unfortunate experience with that specific situation. Learning the hard way is often the only way for some.

For people who have severe allergies or companies and technicians who want to control their environment, the use of sub-standard air filtration systems and devices is not uncommon. The decision, however, to use  a filtration device that will not remove the small, sub-micron sized particles to minimize or reduce the allergy problems is as dangerous as running with scissors. Sooner or later something bad will happen.

Over the counter allergy medicine is at best, psychologically helpful. Most of these are anti-histamines and will provide minimal relief, usually just masking the symptoms. Removal of the allergens or removing yourself from the source of the allergens is the only way to really provide some relief. Just like allowing the child to still hold the scissors but not allow them to run, is only a partial solution to the problem.

General duty air filters that are found in your HVAC return or in your return air grills are good for removing large particles and then only when the air handler fan is running. During the off cycles nothing is being pulled through the filters. It is always best to have your fan setting on the thermostat set on run. While this uses a little more electricity, in the long run it will maintain a more even temperature in all rooms of the home or office and keep the air moving toward and through the air filters. This process alone of running the fan continuously is helpful even if you are using standard air filters.

Pure Air Systems has been manufacturing HEPA and Carbon based air filtration systems since 1985. These commercial grade, certified HEPA systems are used in the residential, commercial, institutional, medical and high-tech manufacturing markets around the world. These systems incorporate some of the most effective and advanced motor and controller devices available on the market today.

Using HEPA filers or HEPA based air filtration systems is still the most effective method of removing the respirable size airborne allergens. The difference in reduction of these particles in using the HEPA filters rather than standard duty air filters is significant. In cases where PAS customers have switched to a HEPA filtration system, over 80% of those with significant allergies found they slept better, had fewer symptoms and needed fewer or no additional allergy medications.

There are hundreds of thousands of blogs posted every day online and almost 90% of all newspaper and magazine articles are actually blogs or produced from blogs. You would think with everyone using computers with spell check software on which they are writing these blogs that they would actually use the software to check their spelling. And some do. Unfortunately the software doesn’t check for correct word usage.

Take the title of this blog for example. This is a term often used in sentences and usually means totally frustrated or not worth doing anymore. However, the way this title is written its’ meaning is somewhat different. Utter futility I can understand….udder futility must have something to do with a non-functioning or frustrated cow or goat, I guess….. Right church, wrong pew.

Companies often use this “play on words” approach to get your attention. It is, in many ways, a rather childish way to get your attention. But it works. If you have read this far you know what I mean. It would seem to me that if your product or service really has any value you wouldn’t stoop to using this type of marketing ploy. But we are.

Over the past 26 years we have had to continually convince the market that true, certified HEPA filters were vastly superior to standard air filters and anything calling itself an air “purifier.” The use of that term was really, and never has been, correct. Nothing actually purifies the air. You can heat it, cool it, blow it, suck it, stir it, move it and filter it. But not really purify it. That connotes making the air pristine and totally void of any impurities.

Yet, the term purifier continues to linger on. Why, we really don’t know. Maybe it just sounds like it does more…..purify versus filter. Maybe its like saying you want a women or man who is pure of heart rather than someone whom needs to filter what they say. Don’t know. But we use it.

The problem with using the term air purifier in front of the filtering device you are promoting, is everyone uses that term. Whether it’s an electronic air cleaner, ozone generator or ionic cleaner….they all use the word purifier some where in the title of the product. First of all none of the three devices just mentioned actually purify the air….in fact none of these devices do much to filter the air. Sorry if you bought one or sell them. We only tell it like it is. It is the Udder Truth.
