I have two 90% furnaces to which 2 years ago I added Lennox Healthy Climate EAC-16 filters for each. Needless to say despite the cost after two years of cleaning 4 cells monthly (or not so monthly as it turned out...) I am done and have to make a switch.
For me a far better solution is going to be a 4-5 inch pleated media filter in the MERV 10-16 range that I only have to change every 6-12 months (no pets, only mild allergies in season, cost of filters not a major issue.)
So... what do I do? The internal cabinet space (where the cells go) in the EAC's are about 20.5 x 21.25 x 5 and no filter really fits that super tight. The Lennox reps recommend a filter they sell which is 19.5 x 19.5 x 4.25 (likely to leave large gaps right?) and I have seen some White Rogers and Emerson filters that are 20.75 x 21 x 5 that seem just barely too big in height. I would *LOVE* to use the EAC cabinets to save on money but any gaps with the filters will destroy the filter performance right?
Should I bite the bullet and just pay to have dedicated media cabinets put in and the EAC's removed, or are slight imperfections in fit in the existing EAC cabinets tolerable? I want to correct my poor choice but try to be cost effective in doing so.
