Inquiry (采购产品): HEPA filters We have Lennox furnaces in our Senior apartments. It's been two years since we opened and we are still noticing white dry wall dust in some of the rooms. I thought maybe a HEPA filter may work. We are using a washable 16" x 25" filter that's approx. 1/2" thick. Is this something you could help us with? If so, could we get a price range? **** Hidden Message ***** Denise Koetje 49401 Company: Stonebridge Sr. Apts E-mail: stonebridge@mykmg.net **** Hidden Message ***** stonebridge@mykmg.net
