Filtrete 24x24x1 Air Filter, MPR 1200 MERV 11, Allergen Plus Odor Reduction, 1 Filter

This definitely helps with odors and dust in my house. Cooking odors used to last all day, over a day... I'd smell it the next morning! Not anymore. I also have 2 dogs and some old carpet that just smells. I can't afford to pull it up and replace it at this time, but this does the trick pretty well for the time being. I highly recommend. I wish these weren't so hard to come by. My 2 local Walmarts are frequently out of stock, Amazon doesn't carry my specific size and Lowe's/Home Depot don't carry them at all or at least around here. I had it shipped (since my local Walmart was out of stock) and it came in good condition. There was slight bending and some of the charcoal had fallen off, but not that big of a deal. It'll still be effective. With ordering something of this nature online and having it shipped, I was fully prepared for it not to be in great condition. I will say it looks like they did their best on packaging it, so no complaints here. I do replace these at least once a month or so, not unusual for any filter I purchase. I have an older unit I'd like to keep in tip top shape and....they just get dirty! You may certainly find these last longer for you. These are worth every penny and again, highly recommended!
