Flex Filter

*Highest quality in the industry - we're so confident in our electrostatic filters that we back them with a lifetime warranty (10 years for commercial applications).

*No polyester - BoAir electrostatic filters contain NO polyester, meaning they are easier than ever to clean, and they're less restrictive than competing products.

*High performance - BoAir filters have undergone independent A.S.H.R.A.E. testing and boast dust arrestance in excess of 90% with initial resistance of a mere 0.10 w.g. at 1200 CFM.

*Easy for you to maintain - BoAir electrostatic filters are permanent, washable and re-usable. Simply rinse with clean water, let dry and re-install.

*The Only filter with VIBAX MI-50 - BoAir electrostatic filters are the only ones embedded with VIBAX MI-50, an anti-microbial agent which helps prevent the growth of mold and mildew.

For the past 12 years, BoAir Inc. has manufactured its high-quality permanent air conditioning and heating filters for residential and commercial use. Our permanent filters are "drop-in" replacements for existing disposable filters and are up to 25 times more effective in removing airborne dust, spores, dander and other contaminants than regular filters.

Installation: Simply install your BoAir Electrostatic Air Filter where your old filter was located. The arrow on the filter frame indicates the direction of the air flow. Air will travel in through the light side of the filter and out through the dark side.

Cleaning: BoAir filters should be cleaned every 4-6 weeks. To clean, remove your filter and use a brush or vacuum to remove dry dust. Next, rinse with water in the opposite direction of the airflow arrow. If necessary, an all-purpose cleaner such as Formula 409® or Fantastik® can be used to remove cigarette smoke residue or other contaminants that may adhere to the filter's media.. After using, rinse thoroughly, drain excess water until dry and reinstall. Don’t expose your filter to direct sunlight or extreme heat for any extended period of time, and never use oil or other chemical sprays on your filter.

A Genuine BoAir filter can be identified by its logo and a unique serial number.
