We have been using these in our home for years. We change them about 2-3 times a year and appreciate this value at SAM's.

Have used both products for a number of years. They both do a great job for there intended use. Both are bought from Sam’s at a good price

Possibly the best whole-house air filter there is, the $10 discount is greatly appreciated in these difficult economic times!!!

Have not opened these yet but it is a product I use almost exclusively and is always a good performer.

Excellent filtration and price. I have confidence in the manufacturer and so happy that Sam's carries these products.

Every. Last. Particle. They fit well and seem to have quality construction. Nothing to complain about!

I have been buying these filters for many years, and they really do the job. Specially, if you have allergies, I would recommend them. Good buy

Excellent filters, I have 2 dogs and bad allergies, these filters make all the difference in how well I breath.

This price is great for 4 of this fillters. Typically pay $20 a piece at other big box store. Thank You Sams

I prefer these filters due to flair ups with allergies. They offer filtration of allergens so I think these are better.
