A lot of quality filters for little cost.
Style: 16x20x1, Style: 16x20x1
Been using these for months, great quality. No issues what so ever. I compared price to the 2 main big box stores and this is the best for your bucks. You get a lot more and they are of the same quality. I used to get mine from a big box store with military discount of 10% and this is still a better deal. They fit exactly like the filter I took out, so size is the same. I live FL and run my AC constantly. These last about 2-3 months each. They do no lose their rigidity. They are built with very high quality material. They catch a lot of dust, you can see how dirty they are when replaced.
PROS
- great quality and last 2-3 months in my AC running constantly
- you get a lot for your money when compared to the big box stores
- catch a lot of dirt, filters are really dirty after use
- very rigid which makes it easy to installation
- reinforced wire mesh
CONS
- None

Top quality filters at a good price.
Style: 20x30x1
These filters are good quality. They are reinforced and hold their shape. They fit perfectly in my filter holder.
The thing I like is that the filters were bundled together and shipped in a sturdy box. Other filters I have ordered showed up in a flimsy box and were damaged.
