Filtrete 319-4 Air Filter, 20 in L, 12 in W, 5 MERV, 300 MPR PACK OF: 4

You run a tight ship at home, from floor to ceiling and everywhere in between. Unfortunately, ordinary home non-electrostatic air filters aren't super effective at capturing unwanted particles. The unique design of the electrostatically charged Filtrete™ basic dust air filter attracts and trap more particles from your air through your heating and cooling system, making quality control a breeze. With each cycle through the filter, your indoor air becomes a little bit cleaner.

Features

• Outperforms fiberglass, washable and non-electrostatic 3 month pleated 1 in air filters for your furnace, air conditioner or HVAC system
• Attracts and captures large particles such as lint, household dust, dust mite debris and mold spores
• Designed with exclusive Filtrete™ Brand three-in-one technology from 3M to trap unwanted air particles while letting cleaner air flow through
• The higher the MPR, the more micro particles such as pollen, pet dander, smoke, bacteria and viruses your filter will capture from the air passing through it
• Change filter at least every 90 days for optimal performance of your heating and cooling system or HVAC system
• A dirty filter will slow down air flow and make the system work harder to keep you warm or cool, wasting energy
• For residential use
• Create a change countdown in the Filtrete™ Smart app, simply use the app to scan the barcode on your filter's packaging, then choose 30, 60 or 90 days for your replacement countdown

Application: For basic dust and lint
