If you have ever taken a trip to the store to get a replacement HVAC air filter, you already know about the hundreds of choices that are available. And when you do not know what to look for, selecting the right one can be overwhelming.
To make it easier, we have broken the process down into three easy steps.
Get the Right Size
Knowing the size of your air filter is step number one. Contrary to most people’s belief, HVAC air filters are not one-size-fits-all. For reference, look at your old air filter. There may be a size printed on the side of it. Or, if all else fails, you can take the filter into the store with you to compare it to the new filters.
Know Your MERV
Once you know the size of your replacement air filter, you will need to understand MERV ratings. Air filters are rated on a scale known as MERV (minimum efficiency reporting value.) The higher the MERV, the more efficient the filter is at removing small airborne particles.
You want an HVAC air filter that is efficient enough to improve your home’s indoor air quality by removing many of your indoor air contaminants but that does not restrict airflow to your heating and air conditioning system.
Understand Air Filter Types
Even after understanding the size and MERV air filter you are looking for, there may still be several options to choose from. Home HVAC air filters are broken down into several main categories. Here are a few of the most popular and the differences between them.
And that is all there is to it. Next time you go to the store for a replacement HVAC air filter, you will not feel overwhelmed because you will know exactly what to look for.
