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

change mine out every month - these are fabulous

Filter are great and a very good price

Filters do a great job of filtering the air in our home and keeping it cleaner.

Purchased because of the cost which was lower than buying separately.

Very good quality. Four per package which reduces the need to purchase more frequently.

Great product, good price.

These filters are excellent, no comparison to the regular ones.

Good filter at a reduced price

Helps so much since my son refuses to clean up after his cat
