With oversized 15 prefilters set in on a V pattern for a 200 fpm face velocitywell worth it if you have alergies or live in LA etc.

For the most part filters are able to get high MERV ratings by using denser material. However a denser filter can make it harder for your furnace to push air through which can decrease your systems efficiency. Likewise the mid-MERV filters also showed decreased air flow relative to the low-MERV filters this time 3 and.

They are similar to fiberglass filters but have a higher resistance to airflow and better dust-stopping ability. It comes with a disposable expanded surface that has a blended media-thickened with cotton-polyester so you are ensured that it wont wear down easily. When it comes to air filters affecting airflow there are three factors at play.

Ideally filter pressure drop should not exceed 20 of the fans rated maximum static pressure. Normally this airflow uses a 2-inch pleated air filter. However a denser filter can make it harder for your furnace to push air through which can decrease your systems efficiency.

Proven to be 60 times more effective than typical one-inch fiberglass filters Honeywell Air Cleaning Filters set an elite standard in. For near zero pressure drop though you can go to a pure electronic filter wires and plates. Lets look at a few examples.

The more efficient filters in this category have a 9 through 12 MERV rating. The amount of the HVACs air flow slowed by the filter is equivalent to the filters pressure drop. A 4-5 filter is usually best for.

To see if the filter is too restrictive you can use a rule of thumb NCI teaches based on the fans rated static pressure. Considered minimum protection fiberglasssynthetic filters prevent dust and dirt from building up on heat exchangers fan motors and other surfaces. Though this is the case with any furnace filter that removes pollutants and dust from the atmosphere within your property as its continuously going to be filtering the air.

A dirty filter will slow down air flow and make the system work harder to keep you warm or coolwasting energy. A clean filter will also prevent dust and dirt from building up in the system leading to expensive maintenance andor early system failure. The size of the air filter.
