In 1985 Pure Air Systems was founded to produce true HEPA filtration systems for the residential, commercial, institutional, medical and industrial markets. The first HEPA system, the model 600H, was 16″ x16″ x 34″ high and weighed 97 lbs. That unit is still made today under the new name 600HS.

Over the years PAS made larger units to handle larger areas and applications and also develoed a smaller portable HEPA unit that is 13″ x  13″ x 21″ long and weighs 30lbs. There are now two versions of that large, portable unit.

In 2018 PAS embarked on an R&D project to develop a small, in-car true HEPA unit that also included a combination prefilter/carbon media wrap. The round HEPA filter is rated at 99.99% at 0.3 microns and will remove particles as small as 0.12 microns. The carbon will remove odors and the prefilter removes the larger particles keeping the HEPA to remove only the sub-micron particulates.

The CAR HEPA prototype is 5.5″ square and 7″ long. It weighs approximately 3 lbs and uses a small, whisper quiet fan that runs off the 12 volt plug ( or USB) in your car. PAS is also in the process of developing a HEPA Holder so you can mount you HEPA in a stratgic location for best air filtration results.

While some very high end cars ( Tesla, Mercedes and some BMW) have high efficiency cabin air filtration, most vehicles have little or none. The CAR HEPA unit will significantly reduce the levels of harmful, sub-micron particulates. These particles include bacteria, airborne allergens and some viruses.

In order to speed up the development process PAS is utilizing 3D Modeling and 3D Printing to create the housing for the unit. The first iteration took just one week to develop and now some tweaking of the housing size is in the works. It may be that the CAR HEPA will be produced on 3D Printers and they could be individualized or personalized with your name and choice of colors.

“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 problem of removing or capturing airborne allergens, dust, dust mite feces and other allergy producing particles has been an on-going challenge for homeowners and with good reason. The new housing construction designs are geared more and more toward the “green” building techniques which mean they are much tighter and more energy efficient. These new, tighter homes have little or no fresh air ventilation and, in essence, the home has become a terrarium.

The ability to capture general dust particles, or dust mite feces and other airborne allergens is normally accomplished by the air filter or furnace filter that is located in the HVAC system. Also, the use of portable, fan powered air filter or air purifying devices are often used and can also be helpful.

However, the use of these filtering devices is effective in removing dust and other particles only if they are airborne. Yes! The particles are not pulled off the floor or other surfaces to the filtering devices. They must be airborne.

The best way to ensure that you are removing these particles is to  always have your HVAC fan setting on your thermostat to the Fan On mode. This means the fan is running all the time even if the heating or cooling modes are not operating. Then, whenever you walk through the house or on the carpeting, or dust or vacuum the carpet, the small, sub-micron particles will become airborne and get picked up through the return air vents or drawn into the portable air filtration device.

The dust particles only become airborne for a short period of time; anywhere from 1 minute to 30 minutes depending upon the size of the particle. This is why constant air movement in the home is necessary to keep the environment as dust free as possible. Again, remember that even thought the dust particles are light and tiny, they will remain on any surface until moved or disturbed.

Once these tiny particles are airborne it is important to ensure that they are properly captured or removed. It is important that the furnace filters and portable filtering devices use a commercial grade filtering media or even HEPA filters for absolute capture.

Pure Air Systems offers a line of dual-layer, polyester ring panel filters that are a MERV 8 rated media. These commercial grade furnace filters fit very tightly into the filter frame and eliminate any bypass around the filter, unlike cardboard frame filters with little or no sealing capabilities.

The ability to seal tightly is important since the majority of the particles captured by the filter are less than 5 microns in size. In addition, the dual-layer media has the ability to hold a lot of dust without any appreciable increase in resistance or pressure drop. This means long life with fewer filter changes.

Pure Air Systems also offers a new, high capacity portable HEPA system that is small ( 13″ square by 21″ long) and powerful. This small HEPA unit can produce up to 500 CFM and offers four speeds, one to suit any room or application. This unit comes complete with a prefilter/carbon media filter and a true, certified 99.99% at 0.3 micron HEPA filter.
