Forget their warranty
Forget their warranty. I have 3 different sizes of Airthreds. The larger one, 1" x 20" x 30" (combo set) for $95.00. The frame isn't well designed and the slipcover filter distorts the frame so that about 3/4" on top and bottom of the filter do not cover the opening. In other words, straight unfiltered air is allowed into your HVAC. To company 1st responded that the frame is only good for 1-2 years? What? Since I'm within 1 year, I thought surely they'd replace. Nope. I have to pay shipping both ways for them to replace their failed frame. I recommend you not waste the money and stay with disposable filters. All their hype is unfounded and dishonest.
