Furnace filters come in various sizes to fit different furnaces including 16x20x1, 20x20x1, 20x25x1 inches and so many others. Even though they may not seem like the most important items or the most interesting when shopping, they play an essential role and are thoroughly recommended for use in most furnace types.
The aim of such filters is to protect the furnace itself. This means shielding it from anything such as dust, hair, and all the other gunk that a return duct tends to pull in.
Though such filters aren’t predominantly designed for cleaning the air as such, what they do is to help the quality of the air in your home as they actively work to remove those pollutants present. Therefore you are less likely to suffer from such contaminated air being redistributed and recirculated around you.
Some people believe that furnace filters aren’t essential and therefore forgo them. However, while they essentially do a good job and greatly reduce any associated costs with running a furnace, the increased costs and long term effects of not using one can be problematic.
Without a filter in place, you will not only be prone to contaminants and therefore upset many allergy sufferers in the home, but ultimately you run the risk of getting debris stuck and lodged into your blower. This inevitably will lead to an accumulation of buildup, wear and tear and more than likely a breakdown – costing you much more to replace the entire filter than it would do to insert a simple filter!
Here we look at a good selection of high quality furnace filters all sized at 16x20x1. These are some of the best rated and popular products currently retailing online and therefore can all be purchased swiftly, thus ensuring your furnace works to its full capacity and best performance for many more years to come.
When looking for any filter type to fit your furnace, we recommend you keep an eye out for those displaying the MERV rating.
Otherwise known as the Minimum Efficiency Reporting Value, MERV refers to the overall effectiveness of the air filter.
Thus, those filters displaying a higher MERV rating will be able to offer a finer filtration process. This means that fewer articles of dust and other airborne contaminants can pass through these filter types.
As a guide, we recommend a MERV rating of between eight and 11, when it comes to purchasing a filter for the furnace. But, we also recommend double-checking with your manufacturer for the MERV rating on your model before purchasing these products. This is because some may suggest a maximum MERV rating for safety reasons.

Final thoughts on Best Furnace Filters 16x20x1 In Size
To ensure the improved air quality, and that these filters do their very best job, experts recommend replacing them as and when is necessary.
Look to the maker of your filters for when you should need to replace them. But, as a general guide, for best performance, we recommend changing them every month to three months – if you have no other manufacturer literature suggesting otherwise.
It’s also worth bearing in mind that there are some months, such as during summer and winter, when your furnace will be working at its peak. Therefore, you may find you have to increase the frequency of your filter changes to accommodate such times.
It’s worth noting that even though this article is on 16x20x1 inch furnace filters, each of these also has several other size variations for you to choose from.
