They work well and last 3 months generally

These are really good filters and the price is good for the quality

We've been using 3m Filters since buying our home 6 years ago. I think these are superior filters.

Have seen much improvement in house dust & air feels cleaner

We have been using these for over 2 years and they are very effective

Great filters for an even better value!

These are great quality to keep your house air comfortable.

I love these air filters and the fact that Sam's Club always has them in 14x20 size is a bonus.

Best quality around and excellent price

These filters are well made and effective
