16x20x1 Air Filters – FAQ & Buyer’s Guide!

If you consider how much money goes into clearing your utility bill, owing to heating and cooling consumptions, you would see how important it is for your central heating and cooling system to be efficient. With an active air filter, you enable your heating and cooling system to run free of contaminants, allowing airflow to take place with ease.

Where the air filter in place is dirty and in need of replacement, you will find that it works as a deterrent against airflow and the system has to work almost twice as hard as it should, thereby driving up the utility bill. You can also find yourself dealing with a breakdown in the end.

Also, where you feel that the airflow is not as much as you would like, it would do you good to check if the filter is clogged as this can also lead to a breakdown. Seeing the above scenarios will have you thinking that you do, indeed need a high-quality air filter. But how should you go about it with so many promising products on the market?

The Selection Process

All the products that we list below have undergone various tests to check their suitability for use in the home, office, and other areas where an effective central heating and cooling system is of the essence. The one thing that is common in all of them is that they work without preventing the flow of air, as they get rid of smoke, dust, pollen, and other contaminants in the atmosphere.

The filters come in the same size, which is thick enough to ensure that the replacement intervals are far-spaced and that the filters work for longer and with enhanced efficiency. You can start waving goodbye to those exaggerated utility bills at this point.

What do you need to know?

One, a good air filter will help you clean the air in your space without getting in the way of air movement. Do you know those allergens that keep triggering reactions with every season? For some people it is dust, for others it is smoke, and for some people, it is every pollutant that dares to come near them. Well, with an air filter, you can keep these contaminants out of your space and away from your loved ones.

Also, maintaining an air filter is a breeze. For most of such products, such as the ones on our list, all you need to do is to remove the old one and slip in the new one and just like that; you can enjoy clean air. This simplicity works great, and you get to save tons of money which you could have used to get a professional to do something which you can do without breaking a sweat.

You also get to have a variety of options from which you can choose. From electrically charged filters to pleated choices, there is so much in store for you. In this list, you will find that we have focused on a few alternatives which meet the market demands, but that is not to say that there aren’t tons of other options out there.

Other than filtration options, you also have many sizes to work with, in this case, being the 16*20*1. Now, here is the thing with air filter sizes. The box may read what you want, but you have to pay extra attention to the actual dimensions which could differ from that. Very many people end up with a size that is a tad too small or too big. Be sure of what you need before parting with money as companies will not refund you for a mistake on your part.

The prices range based on the filtration methods, and you can expect to part with anything from twenty dollars going up for a high-quality filter. Replacement costs also vary. With these few pointers in mind, let us take a quick look at the winners in this category:

How to pick a 16x20x1 air filter

Before making that purchase, you need to think about the minimum efficiency reporting value, abbreviated as MERV, which is something that we will mention a lot in our guide. The higher this number is, the more the filtration efficiency will be. However, you should know that though air filters should not work against airflow, those with higher ratings tend to restrict the flow of air to some extent. As you go higher, you will find that you will come across such limitations. For household uses, anything from 8 will work just fine. Where your house is quite large, you can go with something in the ranges of 10. Also, check the compatibility of the filter with what you have in mind such that you don’t end up getting a low rated filter for commercial use.

You also need to think about the micro-particle performance rating, and anything between 1500 and 1900 will work for your home. This rating concerns the ability of the filter to capture particles that are smaller than 1 micron.


As long as you follow the instructions given by the manufacturer, you will not go wrong. Of course, you can err by getting the wrong size or placing the filter in backward so be sure to exercise caution in this process. Usually, replacements are necessary every other month, but again, that will depend on the manufacturer. Always refer to the manufacturer where you are in doubt.
