[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.

We've been using this air filter for over three years! It's an excellent product. I would not hesitate to recommend it to anyone.

I only buy this filter...well I want the best for my family and right price point and the name 3m behind it.

I have terrible allergies and I feel this really help keep the indoor allergens at a tolerable level.

I trust these air filters to help protect.our family and have confidence that it's taking out all the germs!

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.] Love the Air !!! Love this Fiter and No More Allergies !!

Always buy these and always change them every 90 days. They trap a multitude of particles!

I by this because it's easy to install and works for all of our needs.

I feel confident that this filter does a great job.
