They work good. Happy to have gotten them.

I always used this product so far no problem

Used these for years with great success

good product but price wasn't that much of a saving.

These filters are the only ones we use.

They're fine, no better than others. They work fine

Great that I can get a 4 pack and continue regular maintenance on my A/C at home. Easy to install.

Great price for 4 filters

Great product shipped fast

Great value for four Ultra Allergen A/C filters
