A BETTER HVAC FILTER

Your HVAC system needs an air filter to keep central air conditioner (and furnace) to enable it, to protect the mechanicals from dust and debris.

The best filters also trap indoor pollutants, dust, pet dander, and pollen. Helping to clean the air in your home.

Thicker filters perform best but not every HVAC system can accommodate the thickness, most common size is 1“ thick.

Attention needs to be given to the filtering grade given by the manufacturer.

Most commonly used system applies a MERV number (minimum efficiency reporting value) to each filter.

Some vendors have developed their own systems called MPR (microparticle performance rating) and FPR (filter performance rating.  

No matter the grading system, the higher the number, the better the filter should be, at getting rid of the air pollutants.
