Allergies Are Airborne

Most people who suffer from allergies caused by grass, ragweed, tree pollen or animal dander connect with this allergen through ingestion through their nose or mouth. All of these allergens are airborne and whether you are inside a home, building, school or other indoor environment avoiding the outdoors will not protect you from breathing in these tiny, airborne particles.

Often you will see pollen residue on a table outside or even on windows in your car. However, much of the airborne particulate are smaller than 20 microns which makes them invisible to see with the naked eye. These  tiny particles are carried into the home or building on your clothes as you transport them from one location to another. Then when you walk or move you shake off the allergen particles and they become airborne again which brings them into the air for you to inhale…..again.

Home air filters or furnace filters are not capable of removing these small, sub-micron sized particles. Only HEPA filters will actually remove these tiny airborne particles and the best solution for your home is to install a whole-house HEPA system from Pure Air Systems.

PAS has been making whole-house HEPA filtration systems since 1985 and is the leader in producing a wide range of fan powered, commercial grade, HEPA air filtration systems that use variable speed drive blower/motor units which allow for use as part of your HVAC system or as stand-alone units where you can control the fan speed in 1% increments up to  100% of fan speed.

These systems come with a scanned 99.99% commercial grade HEPA systems, a ring panel prefilter and a true Carbon filter. The PAS housings are all metal as is the blower. Typical life span of these systems is 15 to 20 years.

Filters For Freedom

The filters we are describing here, like our military, will help to ensure your  freedom from unwanted and hard to see enemies. Except in this case we are talking about sub-micron airborne particles. These enemies  are well known by people  who suffer from allergies caused by airborne particles inside or out doors.

With something as aggressive as airborne allergens it would seem that we should be able to actually see them in the air so we could  evade their presence in some fashion. But that is not so. While some of these airborne particles are large enough to see when then collect on the surface of your table or clothing, they are too small ( less than 20 microns in size ) to see when they are floating around your head.

Standard general duty media filters, like the ones you use  in your furnace, are good for removing large particles, those that usually fall to the ground or are easily trapped by your mucus membranes then expelled out again, are not the ones that are harmful. It is those particles that are 10 microns or less that are more easily trapped in our lungs and  create the irritations  that become the allergic reaction that you makes you miserable for weeks and months at a time.

Pure Air Systems began to market their HEPA based air filtration systems in 1985 and today is one of the major suppliers of true, commercial grade, HEPA based, fan powered, high performance, air filtration systems on the market today. Their systems are designed to be used as either stand-alone or in partial by-pass with existing ducted  HVAC systems. These units are powerful built to perform for years with minimal maintenance and only simple filter replacements are needed on scheduled frequencies.

HEPA filters will remove 99.99% of all particles 0.3 microns or larger and approach almost that same efficiency for particles as small as .012 microns. These systems, when properly installed in a home or commercial building, will significantly reduce the amount of respirable sized harmful airborne particles where a real reduction in allergies and respiratory problems is demonstrated.

Make Up Stuff

Hype…used more often than ever before. Why? Because there is more opportunity thru social media to spill your story or talk about your business than ever before. Yes, you can now make up more stuff about whatever and have fewer people verify that what you say is true. Why? Because we are all too busy doing the same thing.

Perhaps another reason for so much well crafted dictum are the social media professional organizations and individuals who will charge you to get your name, company or product thousands of hits, likes, reads, etc,etc. over an entire bread basket of social forums. They design the material to show all the best aspects of the product, idea or concept and support it with confirmations from other organizations…who by the way are also using your organization to support their claims.

I’m not saying that everything you read is partial truths, there are companies out there that have been around for 20 to 30 years that have developed a reputation for performance and execution on a consistent basis. You know these companies and their products and you trust them. Funny, but most of these companies use minimal social media to promote themselves. They have websites and sometimes a Facebook page..but that is about it.

Pure Air Systems is one of these companies. They, like other successful companies, let their products and services speak for themselves. Started in 1985, PAS has been making commercial grade, certified, fan powered, HEPA based air filtration systems for the commercial, residential, institutional and industrial markets that meet or exceed the customers expectation for performance. In the beginning it was very difficult to compete with lesser made and poorer performing competitors systems as any company that made a filtration systems with a HEPA or HEPA type filter claimed amazing performance and reliability.

Over time. customers found the lesser made unit actually did not perform up to expectations as many of these customers purchased PAS products and the differences were startling. Unfortunately having to wait until a customer using a competitors system to purchase yours takes time. That is why Pure Air Systems is now 30 years old and 90% of all the original competitors are no longer in business. Words are fine, but performance is better.

Arduino or Raspberry Pi

Talk to any Elementary school student and the majority of them have either heard of or are working with Arduino Uno or Raspberry Pi mini-computers that can be programmed to drive almost any device. These small, inexpensive drivers are being used in robotics, drone design, optics, cameras, etc, etc. The use of these devices allow anyone with an interest in digital electronics  to effectively learn how to create new concepts and do some minimal programming ( coding ) as well.

Many of the new drone designs ( both copter and winged versions ) use Raspberry Pi computers to control the operation of the drone in all aspects of its flight and telemetry systems. They come is kit form  or purchased as individual modules and the sky is the limit as to what you can build and operate with these new technical toys.

Developing new technology and making it easy to use is one reason why some products make it and others don’t. Pure Air Systems, Inc. is one of those companies that added new technology to their products and make it work better and with more flexibility in operation and customer control.

Started in 1985, Pure Air Systems’ goal was to provide the best, high performance, commercial grade HEPA based, fan powered air filtration systems on the market. Thirty years later and PAS is now one of the leaders in the HEPA filtration arena. With customers located around the world, PAS has created a series of HEPA and Carbon based systems that incorporated the variable speed , ECM motors that would operate in both 120/240 volt, 50/60Hz power sources. In addition, PAS incorporated new digital speed controllers that gave the customers infinite control over the speed and volume produced by the units.

PAS also developed a process whereby you could add more Carbon or other adsorbtive medias with the HEPA, or in the case of applications where gaseous pollutants were the main issue, an all Carbon unit could be used. Flexibility in design, filtration media types and volume control ( CFM ) are the reasons PAS continues to be a leader in this field.

Morbius

In 1956 the movie Forbidden Planet was released and it was one of the best science fiction movies for its time. One of the main characters, Dr. Morbius, played by Walter Pidgeon, had found the remains of an advanced society known as the Krell. The Krell developed a brain boost device that enabled Dr. Morbius to increase his IQ well over 200. The result was a series of wonderful engineering feats accomplished by the good Dr. that eventually became his own demise.

The advancements being made in technology continue to amaze people even today. Science fiction novels and movies of the past 50 years had imagined technologies and devices one could only dream about. Today science fiction has become more science faction. Digital communications devices, space travel, nanotechnology, robots, holograms are all now part of our world and the hits keep on coming. We all carry a smart phone that is capable of accessing all the knowledge in the world and anyone anywhere at anytime. Some advancements in technology, like 3-D Printers have the ability to revolutionize the world…and at the same time create opportunities for evil doers of the world to create harmful technologies. Like Morbius, one has to be careful of what we develop for the betterment of mankind.

In 1985 Pure Air Systems developed one of the first commercially designed, fan powered HEPA air filtration system to be used in a residential application. Very few people knew of or heard of HEPA filters as they were primarily used in the electronics industry and somewhat in the medical industry.  Trying to explain the benefits and features of HEPA filters to the uneducated market was very difficult since most homeowners had never heard the term HEPA before and had even less knowledge of air filters. In the early 80’s electronic air cleaners were still being sold and installed on many HVAC systems and media filters were usually the fiberglass, see-thru cardboard frame types that at best could capture large, leaf-sized objects.

New ideas, concepts, change often bring a lot of anxiety to the masses. It usually takes some significant issue to get people to focus on a subject and take some time to understand it. The advent of “sick building syndrome” in the mid 80’s got the attention of homeowners and building owners alike. The lack of fresh outside air, toxic fumes from building materials and furniture and the lack of any type of filtration for the recycled air in the homes and offices forced the nation to rethink the issue of Indoor Air Quality.

Pure Air Systems developed six new commercial grade HEPA units since its inception in 1985 and is considered one of the leaders in high volume HEPA systems that can be used either attached to existing HVAC and air handler units or as stand-alone systems. Used throughout the world, the HEPA systems from PAS continue to lead the way in performance and quality. Using the most advanced variable speed drive motors and digital controllers, the HEPA systems by Pure Air Systems are proving they are much more than science fiction. Just ask Morbius.

Tombstone Epitaph ..I Told You I Was Sick

For those of you who like to visit grave yards for historical value you will often find some rather creative epitaphs mixed in among the typical “Here Lies So and So” and their birth death dates. One of the more creative mementos chiseled in granite is the ” I Told You I Was Sick” message. I find this funny and somewhat philosophical all at the same time. It may have been done purely as a joke ….or perhaps it was more on the “true” side of their demise. Whatever the case, being somewhat prophetic about your death makes some sense.

It so happens that people who work in dirty environments or in locations where dust, dirt and other airborne debris are present may make the same statement. Even those technicians and medical personnel that are subjected to a wide variety of antibiotic strains of bacteria may call out this phrase. In today’s world of ever changing pathogens it is almost impossible to keep yourself at a safe distance from being the next person to kiss the earth on a permanent basis.

We are constantly surrounded by people…at work, in the stores, on elevators, trains, buses, airplanes, schools, etc. etc. Unless you work at home and live the life of a Monk, you are going to have to come in close proximity to another human being. The latest round of the flu bug has become a nightmare for millions of people and this particular strain is relatively nasty and long lasting. This makes avoiding contact with other humans even more important. Yet still difficult to do.

Almost every indoor environment has a forced air, ducted heating/cooling system that takes all the air through the return air ventilation ducts, heats and cools it and then redistributes the air back into the room. This process aids is circulating all the airborne pathogens and allergens and evenly spreads your germs to the other individuals in the room. This is how and why students at school continue to keep getting sick once a flu epidemic starts. It is a continuous process of passing the viral infection from student to student. This same process is repeated in offices and shopping centers around the world.

Central or whole house filtration systems that incorporate HEPA based filters, such as those offered by Pure Air Systems. PAS has been manufacturing commercial grade HEPA and Carbon based systems since 1985 and has thousands of units installed in commercial, institutional, medical, industrial and residential facilities in North America and around the world. These extremely effective air filtration systems can move from 50 CFM up to 2,000 CFM and work either in conjunction with HVAC systems or as stand-alone units.

The ability of the HEPA filters to remove up to 99.97% of all airborne particles 0.3 microns in size or lager makes this type of filtration system a potential cure for the early grave. These same filters are used in surgery rooms, the CDC and any operation that requires extremely clean air. It has been shown that working and living in environments that use HEPA filters for complete air filtration significantly reduces the number of colds, flu and other respiratory infections. A simple solution to an ever growing problem.

Take a Breath…Take a Deep Breath Now.

As humans we take a lot of things for granite. Rotation of the earth which produces gravity, land to walk on and water to swim in, and the ever present source of life, the Sun.  Being able to breathe the atmosphere in our environment is also something we take for granite. Interestingly most of us know little about the air we breathe. For example, the atmosphere we exist in is comprised primarily of oxygen and nitrogen. Oxygen comprises 21% while Nitrogen comprises 79%..( actually a little less than 79% as there are some trace elements in the atmosphere as well). In reality we are actually Nitrogen breathers although at the surface pressure of 1 atmosphere our bodies don’t absorb the Nitrogen, but they do take in the Oxygen.

When you have a cold or some form of upper respiratory infection you often find it is difficult to breathe. In actuality the lungs are probably full of mucus and the surface capacity of the lungs to take in Oxygen are significantly reduced, therefore requiring longer and deeper breaths just to get the amount of Oxygen your body requires. This same problem exists when you have lung damage due to smoking or breathing large quantities of airborne particulate in your work place over long periods of time. Ingestion of small, sub-micron sized particles create challenges for the lungs as these particulate tend to stay logged in the lung linings and mucus membranes.  People who smoke have difficulty in running or walking long distances as they get “short of breath” very quickly.

Small concentrations of harmful, respirable sub-micron sized particles, inhaled over a long periods of time can also significantly impair the lungs ability to take in Oxygen. Individuals who work in environments where dust is generated on a continuous basis are more susceptible to lung damage than those working in an office type environment. Even when technicians where masks or respirators, these individuals are more at risk than most.

In 1985, Pure Air Systems was founded to provide a series of commercial grade HEPA and Carbon based systems for the residential, commercial, institutional, industrial and medical markets. Today, the PAS line of HEPA, fan powered systems are used in a wide variety of high performance applications around the world. Removal and reduction of small particles are the key benefit of using HEPA filters. Those used by PAS are initially rated at 99.99% removal of particles 0.3 microns or smaller and approach 98% removal of particles 0.12 microns and larger.

Over the years many home owners have purchased the HEPA units from PAS and found the number of colds, upper respiratory infections, allergies and even headaches were significantly reduced. The same is true of those companies and medical operations that used the PAS HEPA systems. Product through-put, reduction in transfer of airborne pathogens and allergens, increase in product quality and reduction in loss work time for employees were all positively affected when using the HEPA systems on a regular basis.

HEPA Filters As Good As A Flu Shot

This year the flu has hit the US very hard. I was up in Indiana for the Christmas Holidays and the majority of the friends and relatives we visited were either sick or just getting over the flu. This story was played out across the US and as of last report 47 of the 50 states had major out breaks of the flu. Coming back to Florida after the New Year I found that the vast majority of those Floridians that went up north to visit relatives were also suffering from the flu bug. Airborne viruses are very difficult to control.

The recommended medical approach to dealing with the flu is to get a flu shot in the summer or early fall to avoid the flu season which usually runs from October through March. And, for many people this preventative measure works. Although while it is possible to get the flu even if you have the shot, the symptoms are usually less severe and are short lived.

Since the flu virus is airborne, sub-micron in size and easily transferred from any infected surface, it is difficult to be in an enclosed structure that uses a forced air fan heating/cooling unit to not have contact with the virus when half the people in the structure are now infected. So when one person gets it..chances are others will as well. I believe many of us saw this take place over Christmas and New Years. Even wearing a mask may not help as the flu virus can live for short periods of time on many surfaces and then it is easily transferred to your hands and then eventually your face ( as we touch our faces up to 500 times per day).

Commercial grade HEPA filters are designed to remove, at a minimum, 99.97% of all particles 0.3 microns and larger with efficiencies approaching over 95% on particles smaller than 0.3 microns.  Viruses range in size from .006 microns to 0.5 microns in size. HEPA filters are the primary filtration media used by the CDC and other laboratories around the world that work with highly contagious and deadly viruses. They are extremely effective at protecting the technicians who work with these contagions.

Pure Air Systems has been manufacturing commercial grade, certified, HEPA and Carbon based air filtration systems since 1985. They are one of the leaders in offering a wide range of HEPA systems that can be digitally controlled to produce from 50 CFM to 2000 CFM. The PAS line of HEPA systems utilize the ECM variable speed motors that are rate 120/240v 50/60 Hz and can be used anywhere in the world. These units are fabricated from powder coated steel and use state-of-the-art digital control systems.  Since its inception, PAS has sold tens of thousands of its units to the residential, commercial, institutional, industrial, medical and specialty products markets in the North American continent and around the world.

The use of PAS HEPA systems in the residential market has shown over time that those homeowners have experienced fewer colds, allergies and flu symptoms than homeowners that just use standard air filters in their HVAC systems. Of course you can’t carry a HEPA filter around with you to work or the store, but you can significantly reduce the transfer of airborne viruses and allergens in your household or small office area with a very high degree of effectiveness.

Understanding MERV Ratings For Air Filters

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

Series 9000 Dimensions diagram 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>

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.

Real Dust, Real Filters

There is a visual misconception that happens to most people when it comes to identifying what objects will do them harm. The normal train of thought is…”if I can’t see it, it won’t hurt me.” In essence, nothing could be further from the truth. Tiny, airborne and surface mounted sub-micron sized viruses and bacteria are invisible to the naked eye but can often be deadly to humans. Finely ground dust from any mineral source or pollen, ragweed and grasses range in size from 100 microns down to less than 1 micron in size. You can only see down to about 20 microns with the naked eye.

Ingestion of small amounts of tiny airborne pathogens and allergens over long periods of time can create severe and chronic health issues. And for the under 3 years, over 60 population the ratio of amount inhaled vs time may be shortened dramatically. Of course, for those individuals who are allergy sufferers or have weakened immune systems due to injury or cancer, even small amounts inhaled over a few days can create significant health challenges. While you can’t control the elements of the environment, you can control your personal environment.

Pure Air Systems has been manufacturing commercial grade, certified HEPA and Carbon based air filtration systems since 1985. For over 27 years PAS has provided high performance HEPA systems to reduce and remove these fine, harmful airborne particulate in a wide array of applications. Commercial, institutional, industrial, medical and residential customers around the world have relied on the performance of the PAS HEPA units to help them maintain a clean, healthy environment.

Air filters, the type you put in your heating/cooling air handler system, have been around for over 70 years. Originally made from metal strands they evolved to fiberglass media then cotton and now man made fibers. They became more efficient over time. However, they also became more resistant to air flow and created adverse air flow restriction problems for the heating/cooling systems. In order to actually remove the small, less than 10 micron sized particles with any efficiency ( up to 90% and greater removal) you require a HEPA media filter. The filters used in most HVAC systems today have an efficiency of less than 20% on these smaller, more harmful particles. And, some furnace filters have almost no effectiveness on anything smaller than 20 microns.

There is a reason that hospitals, clean rooms, surgery rooms, optical manufacturers, food processors, micro-chip companies, medical and commercial laboratories and many other environment-critical operations ONLY use HEPA filters or air filtration systems using HEPA filters. General duty air filters, electronic air cleaners and ionizers are basically useless when it comes to actually removing airborne particulate. The only way to deal with real airborne pathogens and allergens is to use HEPA filtration systems. Real Dust, Real Filters.
