What Type of Air Pollutants Can't a MERV 11 Filter Remove?

A MERV 11 air filter has a higher efficiency rating than most other filters and can capture finer particles and remove more pollutants from the air. Learn what type of pollutants it can't remove.

What Type of Air Pollutants Can't a MERV 11 Filter Remove?

A MERV 11 air filter is known for its high efficiency rating, which allows it to capture finer particles and remove more pollutants from the air. This is especially beneficial for those who suffer from frequent allergic reactions, as it can reduce common allergy symptoms such as headaches, rashes, runny nose, eye irritation, sore throats, and persistent sneezing. Additionally, updating the filter serves as protection against damage caused by bacteria and dust, leading to fewer periods of illness and prevention of infections. However, a MERV 8 air filter cannot filter out the same amount of pollutants as a MERV 11 filter.

The MERV 13 filter is even more effective at removing airborne bacteria and viruses that spread through air droplets. Air filters with a higher MERV rating may filter more, but the thickness of the filter material may restrict airflow. Meanwhile, air filters with a MERV 14 rating or higher are designed for commercial air conditioning systems that can withstand the coarser filter material. MERV 8 air filters are almost as affordable as the least efficient products, so they offer good value for money. If you're trying to choose between a MERV 8 air filter and a MERV 11 air filter, here's what you need to know: according to the EPA, a MERV 8 filter means that it is capable of capturing 20% or more of particles from 1.0 to 3.0 microns in size and 70% or more of particles from 3.0 to 10.0 microns in size.

On a scale of 1 to 16, the higher the MERV rating, the better the filter captures contaminants and contaminants. If you're concerned about the effects of inhaling fine air particles, that's another reason to choose a MERV 11 air filter over a MERV 8 air filter. This comparison chart helps highlight the differences between the two filters to make it easier to decide which one works best. One thing to keep in mind is that a MERV 11 air filter may need to be changed a little more frequently than a MERV 8 air filter. Strict building codes and increased foot traffic generally mean that commercial properties should opt for a filter with a higher MERV rating. If someone has an allergy or respiratory problem, it's recommended to choose a MERV 11 air filter or even a MERV 13 air filter.

For example, the most demanding structures, such as hospitals, clean rooms, and nuclear power plants, often require air filters with a MERV rating of 16 to 20.
