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.

Been using these for 3.5 years now and they are doing a great job plus when you buy them at Sam's on sale, that even a better thing cause it's a great deal!!

These filters catch the dust and pollen that others let through. I am very pleased with these filters, they are not as inexpensive as the others but do a better job., NO MORE SNEEZING.

With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.

We have people in our house with allergies and asthma. These filters have proven to clean the air from our HVAC better than others we've tried. The sale price at Sam's is the best value we've found.

These filters cut dust and allergens down immensely in our home. The down side is they restrict the movement of air thus making the central air unit work harder.

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.

Comes in a pack of 4. Hard ro find size. Got tired of waiting to order elsewhere. Friend came over and easily replaced. I have asthma and know when it is time. Have ordered them before.

I have just changed the filter so I can't say anything about the filter yet. I did have directions that were easy to follow. I had no difficulty installing the filter

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.
