What is the Best Air Filter for Your Needs?

The efficiency rating of HEPA filters is 99.995%. ULPA filters trap more and smaller particles than HEPA filters, with an efficiency rating of 99.999% for particles 0.12 microns in diameter or greater, while HEPA filters are 99.97% efficient at removing particles 0.3 microns in diameter or greater. HEPA filters can be combined with pre-filters to trap larger particles before they come into contact with the main filter. Filters labeled HEPA Type or HEPA Like are not absolutely reliable and should be avoided.

This is a marketing term used by manufacturers, and there's no way to know for sure if they will work at the same level as HEPA filters. HEPA filters are at the highest MERV (Minimum Efficiency Report Values) level and work best with protection against air pollutants. They are designed for most industrial, military and government applications, especially in types of manufacturing where particulate matter in the air is constant. ULPA filters typically allow 20 to 50% less air to pass through than HEPA filters, which results in fewer air changes per hour in the room.

It is also difficult for many existing HVAC (HVAC) systems to adopt a MERV 13 because of the greater fan load of finer filter media, which can actually cause more harm than good and reduce airflow if your system is not designed to handle that type of filter. To provide the cleanest and safest air, you want to get the best filter for your business, office space, school, health center, organization, or home. Understanding your application requirements and the level of efficiency required will help you choose the right air filter for your needs. HEPA filters can be used in any environment, including industrial ones, commercial, health and consumer services.

And if you need to reopen your business during the COVID pandemic, you need to trust that the filter inside your air filtration system will clean the air efficiently. There aren't many filters better than a HEPA one, as these filters offer a way to reduce larger particles.
