Filtrete 9818 Micro Particle & Airborne Allergen Reduction Hammock Filter

I'm very pleased with the product. It was easy to cut down to size and install. Plus, I have a lot more confidence in our air quality now with this product compared to the loosely woven fiberglass filter.

My friend sold me on this particular filter. Every 3-6 months I clean my furnace with this filter. But my furnace hasa built in filter made of horse hair... Every 6 months be fore I used this filter from Amazon was gross I'd have to soak it in the tub get all the dirt out. But with the Hammock filter and the original filter is nice and clean from dust! I have Hot forced air it make's a lot of dust! Your NOT going be sorry using this great filter.... When take it out to change with a new one the old one is grey color!
