great product
Style: 6 PACK, Pattern Name: Standard MERV 8
one of my vents is near 2 exterior doors & my laundry room. due to this, i need heavy duty filters, so my sc doesn't run constantly. these filters work great, so my unit doesn't run non- stop. the first month i started using them, my bill dropped $100, no joke! i have to change them every month, but it's worth it.

What a deal!!
Style: 6 PACK, Pattern Name: Standard MERV 8
What a value at this price! It's great to have close to a years worth at one time! What I appreciate also, is the durability of the product. Many that I've purchased at a higher cost will start to sag before time is up. I do though, only use for 1 month but I'm sure they can last much longer.
Will continue to purchase...

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
