Many hvac units come with a washable type of filter. These will usually be made of foam, aluminum or anti-microbial layers. These have a merv rating of 1 to 4.
You can also use a disposable type which is normally made of fiberglass. These have a merv rating of 1 to 4.
Usually you can hold those types of filters up and see through them. If that is the case, you know they are not doing their job.
Another disposable type is the
pleated filter. These have a
merv rating of 5 to 8. These products have more surface area to catch the dirt.
They also distribute the airflow more evenly. This means the fan is less likely
to pull the dirt through the filter. This is the type of filter that we
recommend for most applications. They are the best value in terms of price for
the filter and keeping your hvac system clean.
Air filters with the higher MERV ratings are sometimes called allergy filters
