14x14x1 Air Filter MERV 11 Superior Pet & Allergy Defense (4-Pack), Electrostatic Pleated HVAC AC Furnace Filters Replacement, Made in USA (Actual Size: 13.75 x 13.75 x 0.75)

These air filters are "correct" for the sizing on factory air handlers from Carrier. No problems with the fit or function of these filters whatsoever, and my HVAC tech even took the name/company to refer to all his clients. Great product and a great price!

These filters are very good,, work as there made to do!! The quality is good!

These are good solid quality filters and a perfect fit

Good filters for the money. I wish Amazon was more careful in packaging. Two of the four filters arrived slightly crushed. Still useable and work well.

Good value

This furnace filter works well and was recommended by our HVAC company. It is the exact size for our furnace since it is not exactly 16x20x1 perfect fit

Edit: there is a difference between a 16x20 and a 20x16. Measure and look for the closest actual size. This ended up being the wrong size size. I don't know why but my hvac is a strange normal size. 16 is too small and will fall the 17 is just barely too big. I'm leaving a 5 star review because the return was handled right away and easily. They either ate the cost or Amazon did but I wanted to do this at the very least.

Great filters great tec support

Filters work as they should. Unfortunately 2 of them were crushed when I received them

If you want to clear the air in your home, these Filterbuy MERV 11s are the way to go. I used to feel like my house was a bit stuffy, but after popping one of these in, everything feels much more light and airy. It’s a breeze to install, and honestly, the results are nothing to sneeze at. The "Purr-fectly" Clean Pros Don't "Pollen" My Leg: The MERV 11 rating is no joke. It traps 95% of airborne particles, making it an a-maize-ing defense against dust, pet dander, and pollen. A "Pleat" for Help: With 14 pleats per foot, there's more surface area to catch the gunk. It’s a very well-rounded approach to filtration. USA! USA!: Being 100% made in the USA is a huge plus. You can tell they didn't cut corners on the industrial-grade beverage board frame. Stay "Charged": The electrostatically charged media acts like a magnet for microscopic irritants. It’s truly attractive technology. The "Drafty" Cons A "Tight" Squeeze: The actual size is 19.50" x 22.50", so make sure you’ve measured up to your expectations before buying. You don't want a gap in your defenses. The "Pressure" is On: Because it’s so efficient, it can increase air resistance. If your HVAC system is a bit long in the tooth, it might have to work a little harder to keep its cool. Changing Times: If you have five dogs like a real party animal, you might have to swap these out more often than the 90-day recommendation. Don't let your maintenance schedule go up in smoke. Final Verdict: "Fan"-tastic Performance! This 4-pack is a solid investment in your health. It’s time to filter out the bad vibes (and the dust) and let your HVAC system blow you away with its efficiency. Don't be a slug—give your lungs the upgrade they deserve!

Filters are good but very tight fit

Works perfect for my Geothermal furnace unit which only fits this particular filter. I’m so happy that I can get this on Amazon because it’s not available in regular stores.

Although they seem to work fine the shipment came crushed on one side.
