Are you looking for the most suitable air filter for your home? If so, you've come to the right place. In this article, we'll discuss the standard sizes of furnace filters, where to buy them, and how to make sure they fit properly. Most air conditioning and HVAC systems use standard-sized filters, but some require the purchase and installation of a custom-sized air filter. The MERV rating of a filter indicates its ability to capture airborne particles, with a higher rating meaning better performance.
Additionally, the FPR (Filter Performance Rating) indicates what type of air contaminants are ideal for capturing each filter. To ensure that your filter fits properly, take out your current air filter and check the size printed on the frame. It should fit snugly into the air filter compartment with a little space around the edges. If the filter is too large, it will wrinkle and reduce airflow, compromising longevity.
On the other hand, if it is too small, it will leave room for debris and particles to enter. Moreover, if there is any resistance to airflow caused by the use of a filter of the correct size, unnecessary strain can be created on the air conditioning unit itself, potentially damaging system equipment and increasing energy bills. For those looking for an even better option than standard filters, there are high-efficiency filters. These are seven times better than a standard filter at removing dust and other particles and have a longer lifespan than other filters (up to two more years).
Now that you know more about furnace filters and how to make sure they fit properly, you can make an informed decision when it comes time to buy one. Be sure to measure your current filter before purchasing a new one so you can get one that fits perfectly.
