Small But Mighty

“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.

A Perfect Addition To Product Line

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.

When It Comes To Filters..Change Is A Good Thing

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.

Running With Scissors

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.

Udder Futility

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.

Pure Air Systems has been making commercial grade, HEPA and Carbon based air filtration systems since 1985. 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.

Willie Make It…Betty Won’t

“Play on words” has been a popular tool of writers and journalists since newspapers were in print. The title of this blog, for example, is taken from some family get together’s when I was a young man. It seems there were a lot of what I call “goofy” phrases used in the early 50’s. This title is one of them. Maybe you have seen it before ….or heard it used. In either case use of this type of phrasing is a great way to get attention from readers.

In today’s world the vast majority of people get all their information, books, classes and social interaction online. The ability to capture your attention has never been more demanding. Getting someone to read something  for more than 8 seconds is now considered a real coup…and if you can get them to read your entire article, blog or product description you are in rare company.

Telling stories and providing helpful, insightful information seems to be one way to get people to view your material. It is for this reason that many companies now incorporate blogs into their websites, like this one, to provide updated and topical data to the market.

Pure Air Systems has published over 150 blogs in the past two years. Over time the number of people reading the blogs has increased dramatically. But most importantly the blogs provide topical information as well as directing potential customers to our website. This is important as all of the technical and operational information about our HEPA and Carbon based air filtration systems are found there. Whether you are a contractor, end user or engineer, the data you need is located on the website.

In addition to the blogs, a special section on our website is designed to provide general information on all aspects of air filtration, indoor air quality, heating/cooling systems and ventilation. We call it “Pure Air University.”  We believe it is important to offer some basic knowledge on all things IAQ so that the public has the ability to make an informed decision when selecting an air filtration system. The information provided through this section is not designed to sell but rather designed to tell.

After being in business for over 25 years, you learn a lot about what information is important to potential customers. They have seen the hyped marketing materials from many of the companies that sell air filtration or air purifier systems. Many of those companies that sold “gimmick” based technology are no longer in business. It seems no matter what you say or how you say it…performance is the only viable marketing tool. We know this and that is why we are still here. Our systems perform as promised…period. No play on words needed.

The Future Is The Past

It has been said that advancements in technology doubles every five years. If the changes in digital communications is any indication of what is happening then that statement is probably correct. We used to have a few years, at least, to adapt to and learn to use new devices and processes. Today things are changing every six months. Or so it seems. For some of us the constant changes are exciting. But for many people the rapid changes clash with their thoughts of how things used to be.

While changes in technology will continue to make extraordinary advances, some things don’t change. Health care problems, for example, are still an issue and those people that suffer from allergies, asthma and airborne contaminants seem to be a constant. With all the advancements in medicine, the ability to cure the common cold or eliminate allergy issues continues to evade us. While there are newer anti-histamines and allergy medicines, people still suffer from all the old symptoms.

The changes in air filtration systems designed to eliminate or reduce airborne contaminants have made some advancements. However,  for the most part, the technology  to capture particles on a filtration media is still basically the same. Some technologies such as electronic air cleaners and HEPA filters have been around for over 50 years. HEPA filters, for example, were developed in 1941 and have set the standard for removal of fine, sub-micron airborne particles.

HEPA filters have undergone some major advancements in HEPA paper design. HEPA filters now share the stage with their cousins ULPA and SULPA. While the standard HEPA filter, which has a standard efficiency of removing particles 0.3 microns or less at 99.97%. The ULPA filters and SULPA filters have efficiencies as high as 99.99995% at 0.12 microns.

Pure Air Systems has been using HEPA filters as their standard media since 1985. Today, all of the HEPA filters used in the PAS systems are scanned HEPA filters, meaning they are 99.99% efficient on all particles 0.3 microns or larger. With over 25 years of experience and thousands of systems installed around the world, Pure Air Systems continues to keep the same high performance standards established at their origin.

It is interesting to note that when PAS introduced HEPA filters to the residential and light commercial markets in 1985, few people knew about these filters. Only the electronics and nuclear industries were actually using these filters. Today, Pure Air Systems customer list reads like the Fortune 500. Pharmaceutical, laboratory, military, government, institutional, micro-chip, optical, medical and many other types of companies use the PAS HEPA systems for critical manufacturing and processing operations.

Homeowners who have been dealing with allergy problems have found some relief in utilizing one of the many HEPA systems offered by PAS. The new HPS 350 and HPS 500 portable units now provide the same commercial grade HEPA filtration for small areas and individual rooms in homes and offices.

Full Metal Jacket

The other day I watched  Stanley Kubrick’s iconic war movie “Full Metal Jacket” on HBO. I had seen this film before but there was a scene that took place in a helicopter that I somehow forgot. The main character, who was a journalist, was hitching a ride in the copter to the front lines. He was sitting next to a soldier manning a 50 caliber machine gun who was firing the gun at Vietnamese running through their rice paddies.

The journalist asked the gunner how many people he thought he had killed? The gunner said,”About 150.” The journalist asked, “Any women or children?” The gunner replied, “Around 50.” The journalist has a shocked look on his face and says, questioningly, “You shoot women and children?” The gunner replies calmly, “Yes.” The journalist is appalled. He looks at the gunner and says, “How can you shoot women and children?” The gunner thinks for a second and says, “It’s easy…I just don’t lead them as much.”

We can justify things we do depending upon what is happening at the moment. Somehow even though we know its not the right thing to do or could even impair our health, we tell ourselves we will correct the problem before it becomes critical. Most often we don’t. This is especially true when it comes to health issues related to lifestyle.

One of the most challenging issues we deal with today is the amount and types of airborne contaminants we inhale every minute and their overall affects on our current and future health. We all know cigarette smoke is harmful both in direct smoking and second hand smoke. We also know working in and around dusty, dirty, commercial and industrial environments is both dangerous and can have an immediate affect on lung capacity and other significant side effects.

Pure Air Systems has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filtration systems since 1985. These systems have proven to be some of the most effective air filtration products for removing and reducing the levels of harmful airborne particles smaller than 0.3 microns. This includes much of the particulate generated by cigarettes and other airborne contaminants.

The HEPA and Carbon based PAS systems can be attached to existing HVAC systems and air handlers as well as being used in a stand-alone configuration. The systems range in size from 300 CFM to 2000 CFM. These systems all use digitally controlled ECM motors so air flow adjustment to CFM levels of less than 50 CFM are possible with all the units. This means the systems can be used in any residential application as well as those commercial, medical and industrial markets where finite control of air flow is critical.

With the continuous bombardment of airborne chemicals, gases, particulate and plant and animal matter, our lungs are being challenged every day.  While it is possible to isolate yourself as much as possible from known, harmful airborne contaminants, the ability to condition your living and working environment with one of our HEPA based air filtration systems is just as important.

Electronic vs Non-Mechanical Filtration

Most people refer to air filtration devices as either air filters or air purifiers. In truth, these two methods are worlds apart in the way they collect or remove airborne contaminants. The term non-mechanical refers to any media type filter;  i.e. fiberglass, polyester, cotton, woven and non-woven, HEPA, etc. Mechanical or Electronic filters would include electronic air cleaners, ion generators, ozone generators, and any filtering device that uses electricity or some type of moving part incorporated into the device.

Before I get any further I do want to state that the term ” air purifier” is a misnomer. Nothing purifies the air. You can purify water or chemical solutions but not the air. However, this term has become a standard part of the filtration market so I will use it.

From a performance point of view, the purpose of any air filter air purifier should be to “remove” the offending airborne particles from the room, house, or area where you live or work. The operative word here is “remove.” The non-mechanical type of filter incorporates a media that has openings in the media itself that make it either more or less dense. The less dense medias like fiberglass filters allow a lot of air to pass through but collect only the larger dust particles and debris. The more dense medias like polyester and some non-wovens like the Filtrete filter from 3M, collect a much higher percentage of the smaller and finer particles.  The less dense media has a lower pressure drop across its surface and has little resistance to air flow. The more dense media is much more restrictive.

Air purifiers, for the most part, use a combination of a positive/negative process to capture airborne particulate. This usually takes the form of a surface or plate that is charged to collect particles that have the opposite electrical charge. It is like running a comb through your hair to build up a static charge and then placing the comb next to small pieces of paper and watch them stick to the comb. Same principle. Unlike media filters that use the collected particulate on their surface ( sometimes referred to as dust cake ) thus collecting more and smaller particles, the electronic air cleaners or purifiers have no depth collection process and once the plates or collection surface gets too dirty or the collected particles loose their charge, the particulate detach and are put back into the air stream.

There are trade-offs in using the two methods. The non-mechanical filters eventually have to be replaced. As they collect more particles the ability to pass air through them is reduced and the pressure drop becomes too high for the fan/motor assembly normally used to pull the air through the filters. The plates or collection surfaces of the electronic devices can be cleaned manually and then put back into service. They also have very little resistance to air flow. The non-mechanical filters, however, are much more effective at removing small, respirable sized particulate.

The type and design of filtration device you choose depends upon the purpose and type of particulate you need to remove. For what it is worth, non-mechanical filters are predominantly used in the following types of applications and markets. Hospital surgery rooms, medical clinics, pharmaceutical manufacturing, clean rooms, isolation rooms, micro chip manufacturing, optics manufacturing, the CDC, medical laboratories and any process or operation that requires the removal of harmful airborne allergens or pathogens.
