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

I've always used Filtrete furnance filters and had no issues

Great product at a awesome price

helps remove a lot of dust particles

Filtrete had the smallest size particle capture. One of us has severe allergies. No brainer.

These filters are the best for our system and at a great price

Works great. It filters dust very well. Feels less allergy.

Great price and delivery.

This size filter is often difficult to find in local stores. This was a good price for them as well

I suffer with Rhinosinusitis and this helps keep the symptoms down
