Comments about Lennox Replacement Filter (75X67) X6667 for PCO-20C - 21 x 26 x 4:
This filter is an unusual size and is only available from a Lennox Dealer. The filter is expensive no matter where you buy it.

Product is great and I order two at a time always so that every six months I can change out my filters.

These filters were less than half the price of the 'professional's' installation who brought them in to install as part of our bi-annual inspection. These filters are exactly the same, and only took about 5 minutes or less to install; remove a couple of screws, pull out the old ones, slide in the new ones, and replace the screws! Save $100 for less than 5 minutes 'work'? YOU CAN'T BEAT THAT! I'll be a 'bi-annual' customer forever, for sure!

I have purchased these replacement filters from IAQSource before. The filters are identical to the ones I've bought from the local Lennox dealer and cost about 1/2 as much. [...]

The main ingredient in almost all water filters is activated carbon, which is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for absorption of chemicals and impurities.
