Very inconsistent in size. The actual dimensions are bigger for a filter in the pack, while a different filter has correct size to fit the vent opening. Very frustrating!!

These are the best AC filters I have ever used! I will never use another brand again. I noticed the air quality immediately for the better. Great price as well.

Nice filters. We buy them when they are on sale. The multi pack is a better deal than buying them individually. They work great! We change them monthly during high allergy times. Can go longer at other times.

I have to buy filters and replace once every couple of months due to my dogs and this is the cheapest place to find them. They are almost $20 any where else.

This model filter is the best. It's a full boxed filter so it holds up well in a strong blowing ac. Doesn't cave in like lot of other filters. And filters good also. Always purchase these. Good price for four pack.

Better quality filter for about 25% less than what they charge at the major home center retailers, and that was before the additional members savings I received.

These filters are bodacious! I breathe better than ever now. I can feel the air pumping through. Clean, fresh, delightful and pure! Other air filters are not as good. These are best that can be!

I've used these filters before, and they seem to work great. I've not noticed and issues with the HVAC system. Sams Club are much less expensive than most other retailers for the same filter.

I I bought generic ones in the past. However, I will not buy them again. I love the Filtrete filters. I’m not dusting as much as I was before. Love the filters.

Product is super, packaging was perfect. The FEDEX delivery left slot to be desired. The tracking process reported as on truck in area on Wednesday. The order was "out for delivery" on Thursday, Friday, Saturday and finally delivered on Sunday.
