It was a great offer for all of them

From the dirt on these filters they are removing a lot of allergens from our home.

Useful to keep your home's air as clean as possible, and improves the operation of HVAC units.

Great value and I like buying in ‘bulk’

Great value for four Ultra Allergen A/C filters

Great to remove pet hair and dust

Not used this product yet, but have used previously and was pleased .

Perfectly constructed & better in bulk!

Always buy these on sale at Sam’s Club. Good value.

Probably overkill rating unless you have hairy pets that shed & dusty environment.
