Choosing the Correct Filter Size

stack of green frame 16x20x1 filters showing nominal and actual size being organized by employee

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.

  • To maintain a healthy lifestyle, as breathing dirty air can put you at risk to develop asthma, allergies, and other respiratory ailments. Plus, old filters can cause system defects which may lead to unwanted expenses via energy costs and repairs.

  • We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. But this is subject to change based on filter size and variable factors for pet owners, allergy sufferers, homes with children, etc.

  • Most of our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system as long as you choose the proper size. But if you see a specific brand name on a listing, make sure it matches your unit model.

  • This varies for every customer depending on specific needs such as the number of vents in your home. However, our selection includes package quantities that range from 1 to 12 filters, so no matter what your situation may be, we've got you covered.

  • After finding the right size, turn off the power supply and remove the cover from your intake vent before taking out the old filter. Then just insert your new filter to match the direction of air flow, replace the cover, and turn the power back on.

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!

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.

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.

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.
