I have tried cheaper brands but I always come back to filtrete. They have different merv ratings for different situations. I have Saint Bernards and lots of dog hair and dander and it takes care of it all.yes they are expensive but worth every penny.

I have allergies and this works for me in our house.

These are very good filters

Great buy! Fraction of the price from other stores and keeps my air clean

Really good filters and a great price

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

Good price on good filter.

Love this brand I have pets and this does the job

Great filters, good price, and they filter allergen bacteria and virus in the air!

high filtration rate. Love it for my allergies
