Filtrete 16x20x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 6-Pack (exact dimensions 15.69 x 19.69 x 0.78)

It fits tight inside the air intake filter housing. I don’t need to tape it in around the edges.

Good quality. Fast shipping. High level of filtering.

I have learned that best A/C - furnace filters are those with the most surface area. This can be easily measured by counting the number of pleats. Also, it is important to keep your air ducts clean which also is a plus. When I change filters every 3 months I marvel at the amount of residue that was retained that I did not have to breathe.

When 3M states these filters last 6 months, they truly mean it! These filters fit snug which prevents whistling and slop in the register like Amazon Basic filters. The filtration rating is equivalent to a MERV 13 filter in a 1” depth. Tons of particulate is captured and come 6 months the filters are absolutely full and need to be changed.

Ok. So, these are so expensive. BUT it’s worth every penny. They last 3 months and after pulling them out you can see all the particulates they’ve cleared from the air. I would definitely recommend these.

I bought these 14x14x1 in March 2022, and they do not accurately fit the spaces where they go, being slightly too large. They have to be smooshed and/or bent to get them into the same spaces where other quality air filters have easily and correctly fit with no issue for over 10 years. Perhaps this was a manufacturing error at that time, dunno. Since the cardboard frame around the filter material is stiff, smashing in the ends is less effective than bending them slightly in half, putting both ends in, and then pushing on the center to smoosh it flat. I suggest if you buy them that you try them soon after purchase to make sure they fit your space correctly, especially during any applicable return window, of smooshing and bending might affect your decision to use them. Attached is a pic of the label that came on mine. Knocked one star off for this issue, which is more troublesome for me because I have to get on a ladder and reach above my head to try to smoosh these into the spaces, including into a space right next to my stairs down, which scares me when I do them alone.

I like knowing the air circulating at home is filtered as much as I can get it. I change my filter monthly now. We moved from a more rural area to a metro location with heavy traffic. In one month of filtering here, it’s brown. It took a solid 3 months to get that way where we used to live. So I’m sure we’re breathing more pollution here when we’re outside. I like knowing inside our bodies can get a break from it because of the high quality 3M filter.

3m Quality doesnt disappoint

Works well but wish they were sold individually as they are very pricey and large to store.

The MPR 1900 MERV filters are designed to effectively filter out airborne particles and contaminants that can irritate the respiratory system. The high MPR rating means that these filters have a high efficiency in capturing particles as small as 0.3 microns, including dust, pollen, mold spores, and pet dander. By using these filters in my air conditioning and heating system, I have noticed that my air quality has improved significantly. I no longer experience allergy symptoms or difficulty breathing in my home, even during high pollen seasons. In addition to improving the air quality in my home, the MPR 1900 MERV filters also help to extend the life of my HVAC system. The filters trap contaminants and prevent them from clogging the system, allowing it to operate at peak efficiency. I am extremely satisfied with the performance of the MPR 1900 MERV filters. They have greatly improved my breathing and overall air quality in my home. I highly recommend these filters to anyone looking to improve their indoor air quality.
