Air Filtration media cartridges aftermarket?

[Cliff Rohrabacher]

I have Lennox AC with three stage filtration: (1) a particle filter, (2) a UV sterilizer, and (3) a 0.3 micron electronically charged media filter.

The UV bulbs and the 0.3 micron filter I'd like to get as the aftermarket items. Reason: I'm cheap and I don't please to spend the $400 every two years that the Lennox people want to swap 'em out.

Does any one know about these things?

Don't know if this is what you want but I get my filters from envirofilters.com.
