A media filter is about 5 inches thick, as opposed to the regular filter which is about 1 inch thick. This increased thickness allows for more surface area in the folds of the filter, and allows for greater air filtration as well as increasing the air quality in your house. The media filter also has pleated media inside that catches particles in your air.
There are many pros to having a Media Filter instead of a regular filter:
Media filters last longer than normal filters
They catch more and keep your system cleaner
They keep your home air quality cleaner and healthier
They are disposable- instead of cleaning it every time, you buy a new one.
They are as effective as HEOA filters by removing up to 99% of particles from the air!
