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.
