Review of 3M Filtrete Air Conditioner Filter, 15-Inch by 24-Inch (9808-12)

Customer Ratings:

I have been using the Filtrete Room Air Conditioner filters for three years and these are great. I cut the filters to fit with the inner AC filter-screen. Tape down and that is it. The amount of dust, dirt and pollution it collects so that it is not re-circulated inside is amazing. I had always suspected that there was dust and pollution circulating, but I had no idea. I could actually feel a difference. Now, I change them out every summer although the instructions say every two months. This is a must have so I stock up on them to save on shipping. I think the Filtera web-site is slightly cheaper if you buy in bulk and it has a $1 shipping promiotion on orders. Highly encourage you to buy once you see how much dirt it collects and how much cleaner your air-conditioned air is after a summer.

I knew the screen filter on my window unit was not adequate filteration for dust, etc so I decided to give Filtrete Room Filter a try. It works great! I've noticed a difference in the dust in the house. (No central air.) It has been three weeks and the filter looks pretty gross so I guess I'll be changing it fairly frequent. Also, I was able to cut one filter to fit two units: 5K BTU + 12K BTU.

I owns 3 Sharp Plasma cluster air purifiers. These purifiers have leaky HEPA filters reducing the air filtration efficiency. To increase the filtration, I used a piece of the 3M filter and wrapped around the original HEPA filter. It increases the lifespan of the more expensive HEPA while improves filtration capabilities. Excellent product!

they allow max, air flow (which uses less eletricity) and move everything from the air. It's like turning your air conditoner into an air purifier as well!

I have fairly bad respiratory problems as well as allergies and bought this product for the first time about a year ago hoping it could possibly help alleviate some of my symptoms . I figured for the price they were asking it was at least worth a try.

My in window air conditioner has one of those washable filters with pores so big it speculate it could only be filtering out the largest particles. I cut the 3M filter to the size needed and taped it onto the inside of the air conditioners normal filter (so the air first passes thrugh the washable filter and the through the 3M filter).

I'm not going to make any outragous claims that somehow my allegies or breathing problems are now cured, but after about two months the 3m filter is just filthy: while it was once white it is now a very dark grey. Common sense tells me that this filter must be picking up alot of things my normal air conditioners filter is missing.

I would have to recommend this filter to anyone. I may be wrong, but again, I just have to assume from what I see that the massive amout of dirt the filter picks up is something that otherwise woud have ended up in my lungs. Overall a great product.
