Things to consider when buying an air filter 

  • Filtration efficiency 

Air filters modify the air quality of your house, and their main goal is to safeguard the HVAC tool from dust particles. It would help if you considered getting an air filter that has coils, as it improves your air filter performance. Most MERV air filters range from one to sixteen, and they can remove particles from 0.3 to 10 microns in size. The higher the rating, the higher the filtration capability. 

  • Resistance to airflow 

MERV air filters have one rule, which is; the greater the filter’s MERV rating, the higher the airflow abrasion and the greater the airflow resistance, the limited air moved by the HVAC fan. You need to make sure you check your air filter as often as you can so that you can know if it is working well or if it has been damaged. The best air filters to use are the ones that are less than 0.01 IWC.
