They are air conditioner filters, they work very well.

Great price for a good filter!

Not the easiest sizes to find. Savings over home stores

Easy ordering and pickup.

These work great for our system.

I was curious how the filters would arrive, they were double boxed and not damaged

These are my go to filters and always buy at Sam’s. Great buy in 4 pack.

Excellent air duct filters

A bit pricey, but hard to find elsewhere.

They work fine and are a A lot less expensive than the hardware store.
