This filter has some many things it can do for a more healthier environment, not to mention the air quality it provides by the features it possesses.

I've used this filter for the last 6 months and it's really made a difference in air quality. Highly recommend if you have an indoor pet.

This is the only air filter we purchase for our current home. Our old home required the thinner filters, but all are always Filtrete.

I have used these filters for years now. The price is a little high but it works out since the filters work well for three months.

Im glad i bought this product we just move into our house and need to clean the air and get rid of the dust and it has really help it out

[This review was collected as part of a promotion.] Makes my house so clean and fresh. Air Conditioner guy said I have the cleanest unit he has seen.

This item measures 4-3/8", not 4" and will not fit into my furnace. I am very disappointed because I trust this to be a great filter.

[This review was collected as part of a promotion.] I have been using these for the last 10 years and love them during alergy season here in Texas.

Since using this product, the air in my home seems to be so much cleaner. Thanks for a great product.

I get these because of my allergies. These really help. They don't make allergies go away but it sure does lessen the severity of the problems.
