Love it, don't have to worry about it for 4 months

This is a real deal for 4 filters!

Have used these many years & they work well.

I am happy because my daughter have allergies with this filter it works to recive fresh air.

These are very good filters

Very good filters for allergens at a great price

Good filters. Only 4 stars since of the filters had a manufacturing flaw that rendered it unusable.

The four pack of filters will last me a while.

Great price, that can’t be beat, great savings!

high filtration rate. Love it for my allergies
