I’ve had a “smell” that I couldn’t place and I thought it may be coming from the register area. Wasn’t strong very faint. These filters are higher quality and it did the trick. Worth every penny.

I usually buy the filter with less coverages, because I do not need the additional coverages, so I had to spend more money. My income is limited. I believe you should have more than one option to choose from.

I believe the filters are good but the first one I put in seemed to get used up pretty quickly. Also didn't appreciate having to pay the shipping fee because they didn't have my size in store.

Good value, had in my size without going to a hardware store. Very good filtration, but (and a good but) you have to replace the filters about once a month with the effectiveness of filtration.

With all the pollen in the air, I don’t know what we would do without these filters. They do the best job capturing the junk in the air. Plus Sam’s Club price is the best.

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.

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.

These were a perfect fit and are doing a great job! With a pug (known for heavy shedding) and a smoker in the house, these filters have made a big difference in the air quality. Great price and fast ship too.

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.

There are cheaper filters but these are of excellent quality. One of these filters lasts us about three months. We have a lot of agricultural dirt & grain dust in the area in which we live. The extra filtration qualities are worth the price.
