Best Air Filters Review

Best Air Filters Overview

The best air filters for the home should do a thorough job of removing as many pollutants and allergens from the air as possible. This means that they should have a very high MERV rating, preferably between 8 and 13. MERV means Minimum Efficiency Reporting Value and is a measurement of how effective the filter is at removing particulate from the air. MERV ratings go from 1 to 20 with the higher numbers filtering out the most particulates.

You may be wondering why you should not go any higher than 13. The reason is that any filter rated higher than 13 has pores small enough to restrict the airflow of the HVAC system. This will result in the fan having to work harder to push air through the filter, which in turn results in a higher energy bill. If you want the best air filter for the home, then you should get a MERV 13 filter and nothing higher.

Key Features of the Best Air Filters

The best air filters will prevent the following particulates from circulating and improve the home’s indoor air quality (IAQ):

  • MERV 8 - Pollen
  • MERV 8 - Dust

  • MERV 8 to 11 - Mold spores
  • MERV 8 to 11 - Exhaust fumes
  • MERV 8 to 13 - Tobacco smoke
  • MERV 8 to 13 - Smoke
  • MERV 8 to 13 - Some bacteria

How the Best Air Filters Should Perform

The IAQ should be good enough that anyone with severe allergies or asthma will never have to worry about an attack caused by harmful particulates floating through the air.

So, if anyone has an airborne infection like a cold, it will not spread through the air to everyone else provided the sick individual remains quarantined.
