A/C also removes particulates... my system has an Aprilaire filter
built in, also UV lamps, I rarely need to dust or vacuum and the UV
does a great job eliminating bacteria, viruses, and mold spores. If
not for the cats I'd only need to dust and vacuum perhaps twice a
year... and I've had one cold in eleven years, probably caught
outside. The Aprilaire filtration and UV lamps more than pay for
themselves by saving on medical bills, and misery. A new filter
element once every two years costs $40, two UV lamps every two years
cost $180. My unit runs 24/7, when it doesn't call for cooling it
switches to low speed. I don't open windows, I don't even have
screens, I hate looking out through filthy pollen laden screens.
