14x20x1 Air Filter, MERV 13, MPR 1900, 2 HVAC Filters

My oldest son having issues with dust and pollen during summer so I have to have best option for air filters and these are great. They thick, catch so much dust and truly been helpful because his nose is improving significantly they true to size and fit great, no issues at all and it just been great to catch all those things and breathe a bit easier at home. Effective and great quality, definitely perfect for summer time!

Extremely good product. Very effective. Great for us allergy and sinus sufferers

These are the best filters available, according to my HVAC service guy. Never had a problem in all the years I've been using them. Best changed four times a year for best results.

The right size, good airflow, easy to install and great pets. No issue with noise and found that they last longer than other brands.

Didn't fit like other 14x25x1. Was a bit longer so I had to rip the the bottom side a bit and force it to fit. We'll how it turns out once I need to replace.

I just installed these filters so I don't know how they will perform in the next couple of months, but super happy with the quality of them right off the bat. They are the closest to a true 24x24x1 that I have found, with a high MERV rate, and quality cardboard housing, filter material, and wire support. I have been on a mission to find something that meets all of these parameters and have been let down by other brands that were just cheap and too small, which allowed air to bypass right around the filter or had no support, so the air would suck the filter in the middle creating openings for air to go around the filter. It seems like many products nowadays are so cheap in quality, so I am very pleased with this product thus far. No pun intended, but it's a breath of fresh air.

Perfect fit and easy to install. It made a significant difference in our indoor air quality during the Canadian wildfire smoke that reached Michigan. Stay safe, Canada. 🍁

I’m using this filters only even I stored a few of other brand I bought last year I feel the air quality is different But price is high

Received the wrong product but got it swapped swiftly. The product itself does a good job.

I use these as a cheap emergency replacement for HEPA filters: when stacked in series two of these 1" filters reduce the 0.3 micron particles 50-fold (98% arrest, verified with a calibrated particle counter). The 12" size is relatively standard , and fits into standard housings. These Filtretes are odour-free, unlike costly HEPA filters from certain supplies (e.g. IQAir). Now, I wish they costed less (hence 4 stars).

good hvac air filter

After a few weeks these are almost black. I can only assume this means all of that "was" in the air. Great filters.
