Due to our high volume of filter sales and low overhead we can offer these filters at THE LOWEST PRICES AVAILABLE ANYWHERE!! BoAir filters are constructed with 5 layers of media (not just three like others) and surrounded by a rugged aluminum filter frame. A unique combination of Polypro with Polyurethane foam media attract and hold the airborne pollutants inside the layers of the electrostatic filter until they are released by washing.

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.
