Good news! The coupon code "SELENA" that saves you 25% off and provides free shipping, has now been extended through 9/30/2013! There's also more good news - the filters are now available in a 2-pack via BuyFilters.com. This is a really great deal, at a more manageable price, so I encourage you all to check them out.
The lofted, wire-backed media (pleated fiber fabric) holds a high amount of dust while allowing air to flow through easily. Furthermore, we have put a lot more media than standard wireback media filters. Most residential pleated filters have 14 pleats per foot; ours is built with 22 pleats per foot meaning that there is about 50% more surface area to work better and last longer than most.There's even a video, showing how these fine filters are made! If you've been waiting to try these out, now's a great time. :)
