Simply 20x20x1 Air Filter, Merv 8, MPR 600, 6 Pack, Furnace Air Filter for HVAC (Actual Size: 19.75"x19.75"x0.75") DUST, Pet, & Allergy Control

What a great value! The filters work and function great and the size was spot on for (what I think) is an odd sized filter. They do a great job and seem to hold up just as well as any of those more expensive ones you may get at a big box store.

I’ve been using the Simply 20x24x1 Air Filters (MERV 8, MPR 600) for a while now, and they’ve exceeded my expectations for a mid-range filter. With pets in the house and some seasonal allergies, I needed something that could handle more than just basic dust—and this filter delivers.The actual size (19.75" x 23.75" x 0.75") fits snugly in my system, and installation was quick. The MERV 8 rating is a noticeable upgrade from lower-rated filters—it's able to trap dust, pollen, pet dander, and even some smaller particles that often make it past cheaper options. Since switching, I’ve noticed less dust on surfaces and a subtle but real improvement in air freshness.Each filter lasts about 2–3 months depending on air quality and usage, and with six in a pack, it’s a cost-effective way to stay on top of filter changes without constantly restocking.For anyone needing solid filtration without jumping to premium prices, this is a great choice—especially for households with pets or mild allergies.Pros:Effectively captures dust, pet hair, and pollenGood fit and easy to install6-pack is convenient and budget-friendlyNoticeable improvement in air qualityCons:May need more frequent changes in homes with multiple petsNot suitable for ultra-fine particles

These filters are a good replacement for my air ducts. They collect a few different microparticles to keep the air cleaner. I do replace them every 3 months and they do need that. But all filters should be replaced every three months. These fit perfectly in the vent. Some filters do not fit as well as these do. There is a spot to mark the date you put them in which i like as a reminder to replace. The cardboard around the filter is a decent thickness so it does not get crunched when installing. The price is better than local brick and mortar stores. very happy with these.

This is my first order of these filters and they seem good enough. Not as strongly reinforced as the brand I was using, but adequate, and some savings in price. They are a little too large for my air return, and I really had to squash the filter in. After I use these I will go back Nordic because of the fit.

These are convenient to have since there are multiple in the pack. It's a good value for the price. I have this on my subscribe and save. Fits great in my furnace and the quality is good too.

Great quality for a cheap price. We've been using these for a few months now and they work well for our home. They're sturdy and really help with our dusty old house. Super easy to install and fit perfectly!

The filter gets the job done. It was a good deal compared to others; however, the quality good, but not the best. I had that in mind when buying the filters.

These filters are awesome! They fit my HVAC system perfectly and were super easy to install. I could tell the air felt cleaner in the house within a day or two. Love that it comes as a 6-pack so I don’t have to run out and grab one every few months. Great quality for the price — I’ll definitely be buying these again.
