Choosing the Correct Filter Size
Nominal Size vs. Actual Size
The nominal size is a shorthand number rounded to the nearest whole or half inch, normally in a larger font (ex: 16 x 20 x 1). Whereas the actual size is an exact measurement, normally in a smaller font, that depicts the filter's precise dimensions (ex: 15.50 x 19.50 x 0.75). All filters have both.
Measuring Your Air Filter
If your current air filter does not have a dimension listed on the frame, use a tape measure to record the width x length x depth to find the actual size. Then round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online.

Now I have a years supply of filters at a reasonable price but they are also thick and do a great job. So glad I got them and I’ll do it again when they run out.

Purchased after a local H. De*** misship. Not only were they cheaper, I got them in record time! Storing them in shipping box in garage. Perfect fit, as good as any I have ever purchased.

I have used many different brands and models throughout the past 15 years for this specific HVAC unit. This one does the job as expected and is a perfect fit. Hard to compare from one brand to the other, as they all do something to attract dust, but this one seems to the perfect balance between air flow and air cleaning!

A well-made filter that is actually is the correct size (many I've bought from other companies were undersized).

There a many filters claiming all sorts of filtration capabilities, and I am sure some actually achieve great things. Unfortunately, most furnaces (like my Carrier) don't fit the filters tightly enough to block the flow fully and some air will just blow past ... making better filters questionable.Coupled with this, a furnace expert that installed a new unit in my home explained to me that unless your furnace is specifically sized for special filters and has the right mounting box, these better filters will reduce the airflow and hence circulation in your home, and in the worst case, can damage your furnace/AC due to overheating or freezing from the reduced air flow. Their recommendation: go with a MERV 8 (like these) or at the most a MERV 11. Their recommendation for extra filtration: install whole-house floor mounted HEPA filters rated for the space, or a more expensive electrostatic unit on the furnace that doesn't restrict the flow.These are solid MERV 8s that I have been using in my furnace for 3 years now (changing out about every 3 months) without issue. FYI - I did try a MERV 11 that actually pulled out of the box mount and ended up in the bottom of the plenum below it. I don't know for sure, but I guess that moisture built up on it (it was slightly damp) and cut down the airflow causing it to be unseated somehow.I will continue to buy these filters for my home system.

Nothing exciting about the product, they work like they are supposed to. I wanted to take time to give a positive review because I received the wrong order and they were able to fix it quickly. With a rush FedEx charge I am sure that they lost money on this order. I appreciate that they put my needs above theirs. I recommend.
