Filtrete 20x24x1 HVAC Furnace Air Filter, MPR 800 MERV 10, Micro Particle Reduction, 4 Pack

Good air filter. Really absorbs much more than any of the air filters that I've used before such as the cheaper brands that you might find elsewhere. I was surprised at how much this air filter picked up in my home within 30 days . I would definitely recommend it, and I felt a difference in the air quality.

Works great but needs frequent replacement. This filter works very well and noticeably improves air quality, but I have to replace it more than once a month. It's not a bad product at all; it just gets used up quickly where I live because we deal with heavy allergens. For anyone with serious allergy concerns, this is a solid choice, but expect to change it often to keep performance high.

We purchase these filters to tape onto a box fan for our bedroom. It absolutely makes a difference in not only keeping the fan very clean, but we don't have to deal with sneezing and coughing as much during allergy season. It works out very well. They usually last about 3 months. Each time we change them out, there is a lot of dust, particles and pet hair that has collected. Well worth the money to stay healthier and cleaner. It gives us piece of mind. We live near a national forest where they do controlled burning, and local neighbors burn bon fires occasionally. This filter is a lifesaver during those times, because I have asthma. This works just as well as the two air purifiers that we have in the rest of the house. Highly recommend.

I have lots of allergies and this filter is worth the price! It really collects the dust. I usually change my filter 6 weeks. This filter really helps control my allergies. Don't bother with the cheap—buy Filtrete—filters.

Great filter! Cleans HVAC units return air. In summer, I change air filters about every month. Seems to be more dust in summer. The price of these filters is why I can change more frequently!!

Very good brand, it absorbs a significant amount of the dust/debris, like it should… Size fits well like it should (As usual) safe for the pets and the ease of installation is so easy for anyone. Particles is also very good

3M makes great AC/furnace filters, they do a great job of removing dust and particles from your AC/furnace intakes. And when you change your filters monthly, buying multiples is just common sense.

It certainly picks up dyst and dirt particles really well and is more reasonably priced than most. i don't like all of the companies saying they last 90 days or 3 months. They darn well know that isn't true. I vacuum constantly, have 2 air purifiers and a $900 wave -r in my air conditioner. I got over a month , maybe 2, not sure because when I changed it I didn't know how long it was that dirty. I will label it with date next time and check more often and hope it goes 2 months.

This is by far the most confusing filter for my return vent. Previous brand filters show the metal on the filter should face the inside of your return vent but arrow says something else on these filters. Read that people said they just changed the arrow on them and others are confused too.

This is not the item I ordered, I ordered a 3 pack that was much less expensive than this one filter. I also had no substitutions marked but was charged for the highest price single item
