Additionally, having an efficient filter in place will reduce the strain on your HVAC system as it will no longer have to deal with contaminants. As a result, you will find that the system will last longer than those without filters. For you to get this advantage, it is necessary that you replace the filter as often as needed as a dirty filter will only pose a challenge to the efficiency of your system.
You can see that all these benefits stem from the use of a good filter and thus, the best place to start in this guide would be the selection process, to help you find something that is a good fit for your space.
When getting the filter, be sure to check the MERV ratings as this will affect how well they work and whether they will restrict airflow. MERV ratings of 4-12 should be okay for residential use. Anything less than this will be less useful and anything higher than this will limit the flow of air. Let’s check out some of the best 14x20x1 filters on the market as of now:

How to pick a 14x20x1 air filter
Measurements
The one thing that you can do wrong when selecting a filter is getting one with dimensions that do not work for your space. Thus, you should start by getting your furnace manual and reading through to see what filters will work for it. You can then go through the various filter options to see which ones meet those dimensions. Where you cannot get hold of the manual, you can opt to measure the size using a tape measure.
Where you already have a filter in place and are in search of a replacement, it helps to use the dimensions of the old one in your quest as you will not go wrong with this approach. You should remember that though a filter states that it is 14x20x1, this may not be the real size.
Take time to go through the actual and nominal figures as the disparity may have you getting something that will end up in your store. The nominal dimensions are what manufacturers write down after rounding off the actual figures, so be sure to keep this in mind.
Type
Your system’s manual will give you pointers as to the kind of filter that you should use, and where you are unsure of what to purchase, this is an excellent place to start. As you go through the option on the market, look for those suited for the use that you have in mind.
Most of the filters that we will cover in this guide work for both residential and commercial spaces. Where the filters are for commercial use, and you use them in your home, you may find that the filtration efficiency is straining your system and it is thus not advisable to use a filter for its unintended purpose.
The aim in this process is to get a highly efficient filter that can get rid of contaminants in the air without posing restrictions in airflow and it is thus best to aim for a balance in the two. The types available are quite many on the market, and they feature different materials and styles. The most common types are the disposables made of paper, fiberglass, cotton, and other materials.
You can also get the adjustable types which work for filter sizes that aren’t standard. You can also get the washable filters which call for added maintenance practices or the electrostatic models which can either be disposable or reusable.
When buying a 14x20x1, remember to take note of the actual dimensions as this will help you know if you are getting the right fit. With this in mind, your purchase should result in a worthy investment. All the best!
