Always use them love them

Great product, works well.

Catches dust, molds and allergens before you breath

Great filters and cost much less then other stores

Good job of reducing dust

Best value with a excellent MERV rating

Nice to be able to get with my regular Sam's order, saves a stop at hardware store.

Very good quality. Four per package which reduces the need to purchase more frequently.

They are air conditioner filters, they work very well.

Does a good job for a family with pets. Pricey.
