How Do Max Electrostatic Filters Work?

Max 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. Max electrostatic filters do not require any power to operate and will replace any existing Air-conditioning/Heating filter without modification.

Permanent Filter with a LifeTime Manufacturers Warranty

No more disposable filters, pads or sponges to replace ever, Guaranteed!! The Max 3-Stage permanent electrostatic air filter is designed to last for the life of your air-conditioning or heating unit. It is washable and reusable, and is constructed from the finest materials available - that's why it is backed by a LifeTime Warranty. To clean simply rinse with fresh water, let dry, and return to service.

Potential relief for allergy and asthma sufferers

Because Max 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.


High Arrestance

Arrestance is a term which refers to a filter's ability to trap airborne contaminants such as dust and mold. Max's 3-Stage filter boasts 87% arrestance which means that 87% of contaminants were trapped during testing.

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 Max 3-Stage electrostatic filter has an initial resistance of a mere 0.08 w.g. at an airflow of 1200 CFM, one of the lowest values compared to other manufacturer's electrostatic filters (Many of the cheaper filters have resistance up in the 0.12 to 0.19 range - higher resistance equates to higher utility bills and lower efficiency).

Anti-Microbial Protection

Max electrostatic filters are 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 3 layers of filter media.

Max 3-Stage electrostatic filters are constructed with 3 layers of media.

No modifications or tools

Max 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 Max filter.

"I've had a few so-called 'life long' air filters over the years but none of them compare to the quality of my new BoAir filter.. and instead of taking up to an hour to wash, my BoAir filter rinses clean in minutes... These filters are great!!" - (Jack M. from Ohio)

" Thank you for restoring my faith in permanent / washable filters. I thought I was smart buying a cheaper filter from a competitor whose filter "looked" better on paper - even the pictures looked flashy. Talk about getting what you pay for - a 'hard-to-clean' piece of trash that now lives in a landfill. When a neighbor showed me his 11-year-old BoAir filter which was still coming as clean as the day he bought it - I had to have one - it's the best!!" - (Trish P. from Florida)

" I wanted to thank you for spending so much time with me on the phone this past Tuesday and wished to express how grateful I am for your advice. You recommended the Clairity ionizer instead of one of your more expensive products and it seems to have done the trick for my allergies. Thank you for being so honest and saving me a great deal of money!" - (Eve H. from New York)

" I know that you generally don't ship outside the US and had to make an exception in my case, so I just wanted to thank you for 'going the extra mile' for me. Your company was recommended to me by a friend in Illinois and she was absolutely right.... extra service with a smile!" - (Molly J. from St. Martens)

" Since installing my BoAir filter two weeks ago my allergies seem to have subsided and I am dusting far less often. Thank you for a great product, for your patience and for your great customer service" - (Annette R. from Florida)

" You would not believe the trouble I used to go to in order to find an air filter to fit my furnace - I should have ordered a BoAir air filter years ago. It arrived promptly and fits perfectly. Thank you for saving me so much hassle." - (Brian F. from California)
