Don't Be Fooled by Cheap Alternatives:

On the fence about which air filter to buy? Maybe we can help... There are countless websites today offering "compatible replacements" for Aprilaire products. These items are advertised as an "equivalent" to the original at enticingly low prices. Don't be fooled by knock-offs and generic brands disguised as the real thing. Time and time again, we receive phone calls from customers who just want to double check that our Aprilaire products are really Aprilaire. Our customers share their stories about purchasing the cheap alternative, only to be disappointed by a product that deteriorated too quickly, was flimsy & fell apart or did not offer the same efficiency as the real thing. In an attempt to save a few bucks, they ended up spending more in the long run. Rest assured that ALL of the Aprilaire products listed on our website are genuine, direct from the factory, OEM products. In a nutshell, you get what you pay for. Spend a couple of extra dollars and buy the real stuff; you'll be happy you did.
