Value & convenience of purchasing the 4 filters instead of purchasing 1 or 2 at a time. The quality is also good with a higher rating than most Fiiltrete filters.

These are the best filters we have ever used in our AC/heating unit. They trap many more pollutants than standard filters, and are very economical in the 4 pack compared to individual purchases.

We use a lot of filters in my house. My husband changes our filters every two months. The price of the Sam Club filters were much cheaper than others suppliers.

Work well, and love that I can get these delivered in my house to change the filter monthly! We live in a very dusty place, so we need good filters, and we need to change them often. This multipack is a good deal, and convenient for delivery.

Does a great job of filtering out dust and fine particles...great for my allergies and I appreciate the assist with keeping dust off the floor and the furniture.

I've used this product for a number of years and by far, it is one of the best. The price is right for this 4 pack. The convenience of purchasing online makes it even better with the free shipping.

This filter is more dense than a cheaper filter, which therefore noticeably cuts down on dust and allergens in my home. Worth the extra expense to me!

I bought these last year to replace my old filters during the heating season and I love them I live in an old home and it seemed so dusty with these it is less so.

Filters work well, fit well and the proof is in the amount of particulate matter seen on the used filter. Its amazing how dirty it gets after a month in place.

I needed a hard to find size. Sam's doesn't carry in store, but they had it on their website for a very good price. It was delivered quickly, wrapped well. No issues.
