1. Fiberglass Filters have been considered the "norm" for Years in Residential and are even used in Commercial Applications as "Roughing Filters" during the "Construction Phase" until the final "specified" higher efficiency air filters are installed.  This does NOT make sense.  During the "Construction Phase" there is a lot of dust and dirt in the air.  Before the Building is even opened for occpancy, the Air Handling Units have been greatly contaminated with dust and dirt, causing the cooiling and heating coils, at building opening to work harder, causing a RISE IN ENERGY COSTS!
2. When the Consumer compares a Fiberglass Air Filter to a > Heavy Duty Polyester Air Filter, they are pleasantly surprised.
3. On Average, a Fiberglass Filter has a MERV Rating of 1, at best 2, while a Polyester Media Filter has a MERV Rating of 4!  A Polyester Media Air Filter is 2-4 Times MORE EFFICIENT than a Fiberglass Air Filter!
4. On Average a Polyester Filter typically costs a Few Pennies more than a Fiberglass Filter, while providing you with far superior perfomance and enhanced Air Quality.
5. Fiberglass Filters, realistically need to be changed 1x per month, while a Heavy Duty Polester Media Filter lasts 2-3 Months.

Our Conclusion and Information you Should Consider:

After 27+ Years in the Indoor Air Quality Business we are attempting to educate the Consumer on the Air Filter you Choose:

We have decided to maintain our "Inventory Levels" on Polyester Media Air Filters" at the best possible levels to serve Customer Demands.

1. For Consumers who are sensitive to Dust and Indoor Air Quality Contaminents, we highly recommend an air Filter of, AT LEAST, a MERV Rating of 4 and posssibly Higher. (Pleat Filters or known as Pleated Filters with a minimum of >MERV 7 or >MERV 8 Rating).
2. For Allergies we also recommend the use of UVC Emitters that destroy all known mold growths, bacterias and viruses known to mankind, including the common cold and flu viruses . <See UVC Emitters>.  <See Air Cleaners, Air Purifiers, Room Purifiers>.
