We just starting ordering filters from Capital Air. They have been nothing but professional for us at ThermalTECH. A wonderful and professional group that is on point, great prices, and excellent customer service. I cannot speak highly enough of this company. The filters they provide are excellent quality that work well in the Commercial atmosphere we work in.

Great for slipping into my homemade mask filter pockets. Best of all is that they are made in the USA so I know they are what it is claimed they are. (I didn’t have to wait two months for them to arrive from China only to find they have been misrepresented. IF it actually arrives, God help you if you have to return it. Honestly, it’s easier to eat the cost of the purchase. Have you ever tried to get customer service on anything shipped from China? It’s a nightmare. Trust me, pay a little bit more and order from someplace in the USA.)
