16x25x1 (Approx 14 1/2 x 22 1/2) Dynamic Replacement Filter (3 Pack)

I bought this Dynamic Replacement filter and put it in the furnace right away because I had to turn the heat on when it got cold this October 17th 2013. I really can't rate it very much since I just started using it. So far it seems like it is doing what it is supposed to do. It is a great price too.

The Dynamic filter system works really well, but that means frequent filter changes. Cheaper and easier to buy here and keep a supply on hand. Thank you.

I made one order of one pack and subsequently made an order of two more packs of three. They look the same and come in the exact same packaging as the very much more expensive filters from the HVAC company I use for maintenance. Glad I found these here.

good quality, correct size, quick shipment, right price.works as well as the much higher priced manufacturer: unit.very pleased so far

Dynamic filtration is the Gold Standard, the air quality in our home is greatly improved since we began using these filters. We've minimized asthma flails and drastically reduced the need for rescue inhaler usage. This product is heaven sent!

Purchased these for replacement for OEM Dynamic Brand A/C Filter.These are just like the OEM but more reasonably priced.Shipping was fast and filters were packaged appropriately to avoid damage.Look forward to purchasing these again in near future.

Just opened the case, slipped it in and furnace operates nicely. Furnace couldn't breathe, old one was filthy needed changing.

These are the same as the yellow ones made by the manufacturer. Great price. Good product. Overall happy about them.
