Looks like good quality

Looks like good quality. Only issues are they are not individually wrapped and the markings are confusing as one side says merv 8 one side says merv 11 and one side says merv 13

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...
