We use to buy the "cheap" drug store air filters and thought they were doing a decent job of filtering. Since we changed to Filtretes our house is cleaner and my furnace internals stay cleaner.

[This review was collected as part of a promotion.] I have been using these filters for a few years now & I notice that (this may sound strange) but not only are we sneezing less, but my cat is also.

I've used various filters and found this model to be very effective. Amazed at what it actually catches from the normal air. Noticeably helps during the allergy seasons (severe hayfever).

I love the idea of cleaner air, but my furnace company told me I needed to change the setting on my furnace when I use a higher quality filter such as this one. This was unexpected news.

[This review was collected as part of a promotion.] I've been using these filters for several yrs and they are great. I originally bought them because my son has asthma.

I know this filter works because when I change it, within the 90 day recommended time, with its fine filter capabilities, it really does its job as the filter is grey with particles.

So far so good. I can't really tell a difference after a week. We recently moved into the house and I am not sure how old the other filter was. I've never bought such a large filter either. No complaints about it.

For the second time in a row, when the air flows to the air conditioning unit, this product literally falls apart. It separates from the flimsy cardboard border.

I have used the Filtrete air filters for many years. They have definitely helped with allergies in our home. I can actually tell from how fresh the air is when it is time to replace.

Our HVAC was installed over 8 years ago. We change the filter every 6 months at during our spring/fall checkups. During a recent home inspection for our refinancing. The inspector asked did we recently change the airvents and ducts?
