How much do whole-house air purifiers cost?
Two kids have allergies, 1 has asthma, and our house is extremely dusty. I want to cut down on the dust, I don’t care so much about killing the bacteria & viruses in the air, so we don’t need the top-of-the-line system(unless it’s under k)
. It needs to cover 1800 square feet.
None of the websites (aprilaire, lennox, etc) post prices, they all refer you to local heating/cooling contractors.

Consumers Report that is on the newstand right now (December 07) has an article on air purifiers. You can’t get better info than that.
You mean one as big as a whole house? Well, pretty expensive I’d guess.
