Replacement Back Filter Set for Fresh Air 2.0 and later. This multi-layered filter helps to pre-clean the air before it is purified in your Fresh Air 2.0 or later.

Perfect fit.

I purchased this unit for my older >10 year old EcoQuest Fresh Air unit. The filter is attached to the unit w/ screws. The screw holes did not align up. I couldn't even attach one side and leave the other unattached. I had to return the product.

As described. Fast shipping. Thanks

good product
