Founded in 1985, Pure Air Systems was one of the first companies to introduce true, commercial grade, fan powered HEPA air filtration systems. The first unit, model 600H, was the base model using a standard 120 volt, 60Hz GE motor, Lau blowers, scanned HEPA filters, carbon media packs and ring panel pre-filters and switches and wire harnesses. All American made. 

Today, Pure Air Systems has 5 different models ranging from 50 CFM to 2000 CFM using the same metal housings, HEPA filters, carbon media packs but with the new variable speed 120/240 volt 50/60HZ motors, digital controllers and pressure gauges. Again, all of these components are currently being made in the USA. In addition, PAS is now one of only three companies in the world that manufacture these commercial grade HEPA air filtration systems.

Making products using US made components in today’s world creates some unusual issues. With most companies using components made in China or other overseas countries, competing with US made components is becoming more difficult. However, the Pure Air Systems units historically have a 15 to 20 year life cycle even in heavy duty operations. The cost may be higher but the performance is unmatched when comparing to similar products made in China.

Looking forpward to 2022 which is beginning to look at lot like 2021 …..again! It seems moving forward is much harder than it used to be. While change is usually constant there are some aspects of 2021 that continue to look more like 2020. Will 2022 actually look more like a new year and less like yesterday again? One can only hope.

For Pure Air Systems, our operation made a major change by moving into our own new facility south of Indianapolis and with more functional space to make our assembly process smoother and easier. We continue to see our business expand as more companies and individuals purchase our commercial grade, fan powered HEPA air filtration systems both in North America as well as overseas. Our new, programmable ECM, variable speed motors offer digital system control that can be customized for any application where accurate fan speed is required for the application with the ability to change air flow automatically or manually.

We hope you have a joyful and prosperous New Year….which ever year shows up. For more information on the complete line of our HEPA and Carbon filter systems, please go to our website at: http://www.pureairsystems.com   our call us on our toll-free number at: 800-869-8025,

In the 60’s Eric Burton of the rock group The Animals sang a song about a lost soul. The name of the song was Tobacco Road. The animals and song went on to become an iconic part of early rock and roll. Along the same lines the product tobacco had also become one the most influential soft drugs in the US and around the world. Nicotine, one of the main components of cigarettes and other tobacco related products, is also one of the most addictive compounds legally allowed in every country in the world.

In addition to the nicotine that is harmful to the user, the cotinine that is released as a result of burning the nicotine is a sticky material that sticks to everything it touches and releases an odor that lingers for a long period of time. Attempting to remove this airborne gaseous compound is difficult as it requires both carbon for adsorption of the odor as well as filter media ( usually HEPA filters) to capture the very fine airborne particulates that are released by the cigarette.

Because of the nature of the two emissions both the carbon and media filters ( HEPA ) need to be changed frequently making it very expensive and challenging to remove cigarette smoke in a room or enclosed area. This is one of the major reasons whey smoking is now prohibited in almost every public building and most restaurants.

As everyone knows, being around smoke from a forest fire is extremely difficult and dangerous as smoke inhalation can be deadly. For California this past year, the forest fires have been nothing short of horrific. Many homes were lost and smoke hung in the air for weeks in many areas of California.

Pure Air Systems, an Indiana based company, has been making fan powered, HEPA based air filtration systems since 1985. Their systems are capable of being used either in conjunction with an existing HVAC system or as stand alone units. The partial by-pass configuration of the units allow for complete filtration of the home environment while also adding the ability to introduce outside, filtered fresh air to pressurize the home.

A homeowner in the San Francisco area purchased a PAS Model 600HS HEPA Plus system to do just that. His ability to bring in outside air through the 600HS unit and pressurize his home allowed him to stay inside and almost eliminate any smoke or odor from coming into his home. In fact, many of his neighbors also came to his house to escape from the smoke that was everywhere in the SF Bay area.

The 600HS unit has three filters. A dual layer ring panel filter to capture large particles and keep the HEPA clean, a 10 lb carbon filter to remove odors and a scanned 99.99% commercial grade HEPA filter to remove sub micron particulate. Pure Air Systems also makes larger versions of this filtration system ranging from 50 CFM to 2,000 CFM. These systems have been on the market for over 34 years and are the best performing HEPA based air filtration systems on the market today.

I am not a huge fan of the band Metallica, but I do happen to like their song, Enter Sandman. It is different than most of their Very heavy metal music and actually tells a story and your  can understand the lyrics. There are other bands whom I don’t follow very much but they, like Metallica, have one or two great songs that get lots of air time on the radio and are on my iPod.

Like my selective choice for music, when I am purchasing certain items I usually go to a certain brick and motor store or shop online where I will purchase that item. The stores may hundreds of other items but I only purchase those select, one or two, items every time.

Many companies that are in the manufacturing business may offer a number of items both standard and custom for customers. However, they often have 80% of their  business derived from 20% of their product line and while they often consider paring down their product line they find customers like the ability to option shop.

Pure Air Systems opened their doors in 1985. They introduced the first high performance, fan powered, certified HEPA air filtration systems for residential, commercial, institutional, medical and industrial application for removal of airborne allergens, pathogens, particulates and odors. Initially PAS only offered one system, the 600H unit. It became a very popular product in the U. S. market and led to the development of 6 more HEPA based systems.

These other units were more powerful and had larger CFM volume capacities and all eventually were fitted with the new ECM variable speed drive 120/240 50/60 Hz digital speed control motors. While the larger systems pushed PAS into the commercial market faster the model 600HS ( now with ECM motor ) was and still is the primary unit sold by Pure Air Systems.

The reduction/removal of airborne particulate is usually accomplished by the use of air filters or filtration systems. The filters may be installed in a ducted heating/cooling systems return air grill or as a stand alone unit that circulates the air in a specific room or building. These types of filter systems are the most effective as they allow for circulation of the air within the room and while keeping the room temperature and humidity levels constant.

On the other side of the equation is the use of pressurization to reduce particle levels and/or maintain a higher degree of fresh air in a room, building or environment. To pressurize any room or space you simply need to draw in or pull in enough air from an outside source to change the pressure gradient in the room from either negative or static to a positive pressure room. We can all identify with positive or negative pressure as seen when we enter a large building or office and when opening the door the air blows out into your face ( positive pressure) or you have some difficulty opening the door ( as it seems to be pulled away from you) and overcoming negative pressure.  Another way to identify positive or negative pressure in a room is to open the main door about 1″ and take some smoke or a piece of tissue paper and place it at the door opening. If the smoke or paper moves toward the opening the room is negative, if it moves out toward you the room is positive.

The use of positive pressure as a means of filtration or “room cleaning,” has some major drawbacks. First, the air you bring into the room would probably be from an outside source. Although in a large building you could pull air from any space in the building and pressurize the room but that air may be just as dirty as the air in the room you are attempting to clean. Therefore, using an outside air source for pressurization is usually better but is comes with some costs.

Unless you live in a part of the country or world where the daily average temperature is around 70 degrees fahrenheit  and the humidity is 40% or less, bringing in outside air to pressurize a room will substantially alter the temperature and humidity in the pressurized environment.  In order to use pressurization effectively you would need to introduce at least 30% outside air as it relates to the amount of air being heated or cooled in the room.  For example is you have a room that circulates and conditions 600 CFM through its heating/cooling system you would need to introduce at least 180 CFM of outside air to remove some of the  airborne particulates or contaminants.

This process is often used in smoking areas in bars and lounges and in locations where odors, gases or fumes are being generated and dilution by introduction of outside air is the least expensive alternate. The amount of air introduced from the outside would vary depending upon the type of contaminant as just mentioned. It may be that up to 50% dilution is required to effectively reduce the levels of contaminants, however, this large amount of air will displace half the air in the room so some form of vent is needed to allow the fresher air to come into the room and push the contaminated air out of the room. It will also significantly impact the heating/cooling/humidity levels in the room or space.

There is a small smoking phenomenon hitting the markets worldwide…e-cigarettes or electronic cigarettes. The electronic cigarette was developed in China in 2004 and has now become one of the more popular concepts in removing yourself from smoking nicotine filled tobacco and eventually quitting smoking altogether. However, for many people the act of smoking while drinking or the habit of just having something in their hands to keep busy is enough to make them full-time users and that is because you can now control the amount of nicotine.

An electronic cigarette, also known as an e-cigarette, personal vaporizer or PV, is an electronic inhaler that vaporizes a liquid solution into an aerosol mist, simulating the act of tobacco smoking. Electronic cigarettes are no longer marketed as smoking cessation aids or tobacco replacement in most countries. There may be similarities between conventional and some electronic cigarettes in the physical design and the nicotine release can also be chosen by the user, with some people choosing no nicotine at all.

The benefits and risks of electronic cigarette use are a subject of uncertainty among health organizations and researchers. Limited controlled studies are available due to the relatively recent invention of the device. Laws vary widely concerning the use and sale of electronic cigarettes and accompanying liquid solutions, with pending legislation and ongoing debate in many regions. But the challenge to the tobacco industry is very big. Once someone switches to the electronic cigarette version, they seldom go back to the original design.

From a health issue stand point, the vapor produced by the e-cigarettes is considered somewhat benign. However, having any type of nicotine added to the liquid quickly changes the second-hand liability of the device. The other issue is the potential use of these new devices in restaurants, bars, public buildings, medical facilities, etc., where traditional cigarettes are now banned. Not to be facetious, but this is a possible smoking gun. Since no one really knows the true chemical make up of the vapor produced by these e-cigarettes it is difficult to make any health determinations. These issues will come up and there are already groups who support the e-cig movement asking to be allowed to smoke in now no smoking areas.

Removing cigarette and cigar smoke has always been a challenge, even for companies like Pure Air Systems who have been making commercial grade HEPA filtration systems since 1985. Removal of fine, airborne particulate generated by traditional cigarettes is difficult. Much of the smoke goes into a vapor phase, much like the vapor produced by the e-cigarettes. In cigarette smoke as in vapor smoke, it is not what you see that hurts you…it’s the small, tiny, sub-micron particles that are inhaled into the lung linings and mucus membranes and tend to stay there. Over long periods of time these particles can create a wide variety of respiratory dysfunctions and lung cancer is one of them.This movement toward an electronic smoking system will eventually take a big bite out of the tobacco industry and look for these traditional cigarette companies to get into the e-cigarette market soon.

In 1954 Alfred Hitchcock directed the movie “Dial M For Murder” starring Ray Miland, Grace Kelly and Robert Cummings.  The story is about a husband who carefully plans to have his wife murdered. If the plot goes as planned the wife is gone and the husband is never suspected. As with many ideas, controlling all aspects of the concept often is seldom accomplished.

In the world where air pollution and airborne contaminants are a common occurrence, it is interesting to see how many individuals, maintenance companies, contractors and IAQ professionals under estimate the ability to control the levels of these contaminants. The initial plan often include using the least expensive filters or filtration device as many mistakenly believe one type of air filter is as good as another. This is seldom true.

One of the common mistakes is to only look at the particles we can see with the naked eye as the harmful contaminants. The irony is that particles you can see with the naked eye are about 20 microns or larger. Most of the particles that are harmful or that are aspirated into the lungs are less than 10 microns in size. These tiny particles are not easily trapped in general duty filter media, which are typically the type used when attempting to provide a cleaner environment.

Most HVAC systems use filter racks located in return air grills. These are normally the place for standard pleated media or ring panel filters and typically have a low MERV rating. (usually  MERV 5 to 7) These air filters will capture almost all of the 20 micron particles but their efficiency drops off dramatically as the size of the particles gets smaller. The other variable to take into consideration is the resistance of the filters relative to their overall efficiency.

The standard air filters used in most HVAC systems have a lower efficiency but also a lower pressure drop or resistance. This is important in the scheme of things as putting in a more resistant filter would reduce the air flow. On the up side though, they would be more effective in removing the harmful airborne contaminants.

HEPA filters are extremely effective at removing very high percentages of extremely small particles, those particles that are truly harmful. Their standard efficiency is 99.97% at o.3 microns. For comparison, the standard air filters used in most HVAC systems are approximately 15% to 20% effective at removing these tiny particles and that only takes place close to the time they have to be replaced.

Because of the design of HEPA filters, they are normally part of a system or package that also includes another blower/motor assembly to assist in moving the air across the HEPA as well as picking up the additional resistance across the filter. For this reason most HEPA filter systems are attached in a partial bypass mode to the HVAC ducting systems so no additional resistance is added to the entire air handling unit.

Pure Air Systems has been making HEPA and Carbon based air filtration systems for over 26 years. They have a HEPA system that will work for any type of environment and any kind of HVAC system. Even for areas where no ventilation systems exist.

Don’t you just hate it when someone is trying to make an important point and they use the wrong phrase or terminology and the whole conversation goes down the drain. Using mixed metaphors can do that to you. Once you do it, you lose all credibility. It’s happened to me and I’m sure on occasion it has happened to you.

Giving a presentation on your company’s product or service in front of an audience, whether it’s 3 people or 30, requires some preparation and practice along with a great power point presentation. Without the practice or the right tools the entire message can get lost in the shuffle. So to speak.

I think you get my point. Getting the correct information in the correct manner and style appropriate for your audience is critical to making a lasting impression. But more importantly, when you have a captive audience full of potential buyers you need to nail it. After all, in today’s difficult economic climate, you need all the new business you can get because it’s a jungle out there.

When writing the text for the Pure Air Systems website, it was decided that the material would be geared more toward education and indoctrination of all things “air filtration” and “IAQ,” rather than a “let me tell you what I’m going to do,” sales type pitch. The current website is a direct result of that process. Don’t get me wrong, it didn’t start out that way. But this is now the 7th iteration of the site and  all the changes were made as a direct result of customer feedback.

When dealing with technical terms and products, it is important to look at your audience as novices when it comes to your particular product or service. Just because someone uses a similar product or service doesn’t necessarily mean they actually understand how it works or why it works.  And, if they don’t understand the basics they can easily be swayed into buying some other product that claims to be as good or better than yours but is less expensive. Education is the key.

When you go to the Pure Air Systems website you will find an easily navigable site, with tabs that indicate exactly what they are and the information under the tabs is in sync with the tab names. Additionally, the information in the “Pure Air University” section is specifically written for the laymen as well as the knowledgeable. It doesn’t get any better than that.

So, if you are at wits end, and you want information that separates the men from the boys, the wheat from the chaff, and puts you in a better light, then go to our website for information on the best HEPA air filtration systems on the planet. You’ll be glad you did. Find us at: www.pureairsystems.com. Or call us at: 800-869-8025. Thanks a bunch!

If you go to the comments section of any article published on-line that discusses the plight of the American manufacturing machine you find people complaining bitterly about the fact that nothing is made here anymore. In truth, the vast majority of major products are made here in the US. However, almost all of the consumer electronics and most of the general duty appliances are made outside the U.S., and therein lies the problem.

If you use a cell phone, computer of any style or type, tablet or other digital communication device, more than likely it is manufactured overseas. Yes, many of these companies, like Apple, are based right here in the U.S, but they have their devices made some place else. Small appliances also fit into the same category. Yet, it is interesting to note, consumers may complain about the perceived lack of American made products, but they will purchase the imported brands even if there is a similar product that is actually made right here. The main reason…price. Over time people have rationalized that one companies product is the same as another companies product and therefore price is the deciding factor.

Pure Air Systems has been manufacturing commercial grade, certified HEPA and Carbon based air filtration systems since 1985. These units were and still are made right here in the USA. In 1989 PAS began putting “Made in the USA” stickers on each unit. It was our way of telling people this product was fabricated from all US made components. The intent was to assure the public that we were not importing the products from overseas.

Over the years a number of  U.S. based companies offered alternate air filtration technology based systems that in some case competed with our smaller units. The majority of these systems were fabricated overseas and they were usually of a lesser quality but also considerably less expensive than our systems. And even though PAS has repeatedly shown to meet or exceed the performance requirements of our customers, many individuals and some companies continue to purchase the imported products.

Today, Pure Air Systems continues to manufacture all of its systems here in the U.S. Some of the electrical components and a few mechanical components are fabricated overseas as these required parts are no longer made in the U.S. However, our products are still some of the most powerful, effective and sophisticated HEPA air filtration systems made today. Customers from around the world now use our filtration systems and our reputation for quality and performance is seldom challenged.

There is no doubt, that companies around the world have access to the same technologies and components and the need to continue improving our products has never been greater. However, we will never sacrifice quality and performance for price. We know what is required to provide our customers with the best available air filtration technology and they rely on us to maintain that premise.
