To insure that all the air and pollutants go through the furnace filter and not around it, our filters feature our patented anti-bypass seal. When your air conditioner or furnace turns on, the difference in pressure causes an air tight seal. No bypass means you’re filtering 100 % of the air.

You can also choose to add an activated carbon or zeolite refill, if you wish to control odors and V.O.C.’s.
Replaceable furnace filter refills assure a new, fresh furnace filter every time. No more guessing if your furnace filter is really clean and healthy.
Yes it can! This is a very common cause of your AC freezing. If your filter is clean, it may be too restrictive or you may have a bigger problem. Custom fit aluminum frame filters are a good way to ensure you’re getting max efficiency and not overly-restricting air flow.
It’s important to have the right sized AC filter. One that’s too small will allow dust, debris and other particulates to move past the filter and get into the AC handler. This is the number one reasons AC units break down. Custom fit aluminum frame AC filters are the only way to ensure 100% effective filtration of the air going into your AC unit.
You should NOT. Filters are the only thing stopping dirt, particulates and debris from damaging or clogging up your AC unit. An aluminum frame custom fit filter is the only way to ensure you’re preventing 100% of this debris from sneaking past your filter, since cardboard and plastic filters don’t make a 100% seal.
YOU should not be cutting an air filter to fit the size of your frame. Filters are made to fit that area, and most cardboard or plastic frames do not fit well. Custom fit AC filters are the most effective air filters you can have on your AC handler.
Custom fit AC filters create premium air quality inside your home. Ours are made from an aluminum frame with electrostatic replaceable filters. These filter 100% of the air coming through the filter frame because they do not leak like cardboard or plastic filter frames. They’re also refillable, cheaper than a standard filter and recyclable, so they are zero waste!
