Please note: This is a genuine BoAir electrostatic air-conditioning and heating filter, not an imitation. Genuine BoAir AC/furnace filters do NOT contain polyester which tends to become difficult to clean over time. This 5-Stage filter is made from 5 layers of filtering media. A Genuine BoAir filter can be identified by its logo and a unique serial number.

This filter is "flexible" and its super-slim design works exceptionally well in window/wall mounted units as well as home central air/heat units and returns - These filters are also commonly used in marine/boating and recreational vehicle applications.

How Do BoAir Electrostatic Filters Work?
BoAir electrostatic filters are made from special materials that develop their own safe electrostatic charge as air is drawn through the filter by your air-conditioner, heater or furnace - This charge attracts contaminants like a magnet. BoAir electrostatic filters do not require any power to operate and will replace any existing Air-conditioning/Heating filter without modification.

The Flexible Air Filter with a 7 Year Manufacturers Warranty
No more disposable filters, pads or sponges to replace. The BoAir 5-Stage permanent electrostatic air filter is designed to last. It is washable and reusable, and is constructed from the finest materials available - that's why BoAir backs its 5-Stage electrostatic air conditioning / heating filters with a 7 Year Warranty.
To clean simply rinse with fresh water, let dry, and return to service.

Potential relief for allergy and asthma sufferers
Because BoAir electrostatic air filters are effective in trapping pollen, mold, bacteria, dust, pet dander and many other airborne contaminants, they can potentially reduce or eliminate allergy and asthma symptoms - BoAir electrostatic filters are much more effective at removing airborne contaminants than those cheap disposables, and they're more effective than most other electrostatic filters.

Impressive Specifications

High Arrestance
Arrestance is a term which refers to a filter’s ability to trap airborne contaminants such as dust and mold. BoAir's 5-Stage filter boasts 90% peak arrestance which means that up to 90% of contaminants are trapped by the filter.

 

Ultra Low Resistance
Resistance is a term which defines how hard your air conditioner / heater needs to work in order to pull air through the filter. Filters with low resistance allow the air conditioner / heater to breathe more easily and to operate more efficiently. A good filter with low resistance will save you money and reduce repair bills when compared to a filter with higher resistance because your air conditioner will operate fewer hours per day. The BoAir 5-Stage electrostatic filter has an initial resistance of a mere 0.10 w.g. at an airflow of 1200 CFM (Many of the cheaper filters have resistance up in the 0.15 to 0.19 range - higher resistance equates to higher utility bills and lower efficiency).

Anti-Microbial protection
BoAir electrostatic filters are the only ones embedded with an anti-microbial which effectively limits and controls bacteria, mold and mildew, and helps to reduce odor.
Note: Washable filters that have not been treated with an effective anti-microbial have been found to actually encourage the growth of mold, mildew and bacteria which may be hazardous to your health

Constructed with 5 layers of filter media with a sewn vinyl edge
BoAir 5-Stage electrostatic filters are constructed with 5 layers of media. The filter edge is hand-sewn vinyl - the filter will never corrode or rust.

Available in any size up to 600 square inches
BoAir 5-Stage electrostatic filters are custom manufactured to order and can be made to any size up to 600 square inches.

No modifications or tools
BoAir has designed its electrostatic filters as “drop-in” replacements for your existing disposable filter. You won’t need to make any modifications to your existing equipment. You won’t need any tools to install a BoAir filter.

Save money over high-quality disposables
Replacing your household a/c or furnace filter each month with a high quality disposable filter will cost you about $145 each year - or $725 over a five year period, and that doesn’t include gas money or your time wasted running to the store. Compare that with the one-time purchase of a BoAir 5-Stage Flexible electrostatic filter for under $76!!
