[This review was collected as part of a promotion.] Replaced a very dirty filter that was more than 2 years old, yikes! We don't use the heater very often. No matter, the filter was full of dust. Going to change out earlier next year.

[This review was collected as part of a promotion.] I have bad allergies, an old dusty house and two cats. This product works really well and helps me fight my allergies.

Online order for card cash back. In store pickup while doing other shopping. This is a quality filter that outperforms the old fiberglass. With the quantity package and discount, this is a value.

The Allergen Defense line provides you with a high quality filter without breaking the bank. I have used them for years and it never ceases to amaze me how much dirt and debris it can hold.

I have always used Filtrete Filters. Why? Because they do exactly as they claim. I did read the reviews before purchasing this particular filter. I purchased these from Sams online. Arrived quickly. Free shipping. I recommend!

[This review was collected as part of a promotion.] I've tried other brands of filters, but have not found any that work as well as Filtrete. I is the only brand I buy now.

[This review was collected as part of a promotion.] I use these all the time, and it traps so much of the allergens, that our son breaths so much better now.. We have several cats, and wow what a difference in our home. wonderful product....

[This review was collected as part of a promotion.] Let this filter go 6 months and got a good layer. Proof it works well and I should stick w every 3. We have a cat and two allergy prone kids. This product makes a difference!

They are 13.5 x 19.5 x1. Now I have to tape them in the vent.

[This review was collected as part of a promotion.] This filter cleans the air better than most! We used to have allergy problems but don't now!
