[This review was collected as part of a promotion.] I have been using Filtrete filters for 20+ years. I feel that they work extremely well to reduce the dust and allergens in my home. I replace them every 3 months as suggested.

Product size states 20x25x4. Inconspicuously designated as slim fit. Actual size is 19.5x24.5x3.25. This is new. I have purchased this product for many years. This is the first time I have encountered this.

I purchase the normally 3M 1000 'red color' wrapped filter that I used quarterly. I think it works wonderfully. It is the best product for me for my house, quality wise and price wise.

Am very satisfied with the effectiveness of the Filtrete 16x25x4 filter. I have a variable speed fan on my HVAC unit, and run it 24 hrs. 365 days. My house stays fairly dust-free. I am happy to let the filter do the work for me!

I have brought several of these filters after Katina we had a lot of dust in our home from replacing the sheetrock and these filters have made a big difference.

My furnace technician usually has a less expensive filter to leave with me when visiting for my annual furnace check but when he sees I have a Filtrete Healthy Living Air Filter he says that is a much better filter and I should stick with it.

I absolutely love using Filtrete filters. I choose the Healthy Living product because it does and takes care of it all. They work so well I do not even have to dust the furniture anymore. Filtrete is worth every penny and is a time saver to boot.

I've been using the Filtrete Healthy Living Air Filters for many years now and have been extremely happy with the results. Having 2 dogs, this filter catches a lot of the extra "fluff" in the air.

bEEN BUYING THIS PRODUCT FOR YEARS NOW AND I'M NEVER DISAPPOINTED. THE AIR IN THE HOUSE ALWAYS SMELLS CLEAN. I HAVE ALLERGIES BUT THEY DON'T PERSIST WHILE I'M IN MY HOUSE. THEY ARE NOT CHEAP BUT WELL WORTH IT

I've been buying the Filtrete filters for at least 15 years, and as they've increased the quality of the product, I've moved with them. So far, at 75, with a couple of dogs, and candle burninf, and wood stove, I'm still well. Thank you Filtrete!
