Replacement Filters

Our stock filters are made to fit the Holmes HEPA Air Purifiers, that use the "A" sized filter. However a custom sized filter is possible. After testing several brands of HEPA fan type purifiers we decided to concentrate on the Holmes brand as the units had the best air flow, features, and reliability for the price.

The A filter will fit the shorter tower and the B filter is approximately twice the size of the A filter and fits the taller tower. In the case that you happen to have a different HEPA fan let us know the type and model number of your unit along with the filter cavity dimensions and we will build a filter to your requirements. The cost difference from our stock filter to a custom filter should be minimal as all of our filters are hand built. The cost is determined by the dimensions and the amount of filtering medium to be loaded into the filter.

1 "A" Filter - $34.00usd*

2 "A" Filters - $60.00usd*

1 "B" Filter - $47.00usd*

2 "B" Filters - $90.00usd*

* includes free shipping in the continental US

TECHNICAL: I would like to offer a brief explanation of how the filtering medium removes Ethylene gas from the environment. The medium that removes the gas is a clay embedded material, which absorbs the ethylene instead of catching it like duct would be captured by a common pleated paper filter. A chemical change happens withing the medium and the Ethylene gas is neutralized. This means that over 90% Ethylene that enters the filter will not be distributed back into the environment.
