Components Of Air Filtration Systems

You’ve probably heard about MERV, but do you know what it stands for? It stands for Minimum Efficiency Rating, and MERV refers to filter efficiency. You’ve also likely read about EPA particulate matter regulations and Fabric filters. These are all important components of air filtration systems.

MERV

The MERV rating is a useful metric to consider when selecting the best home air filter. A MERV rating indicates how effective your filter is in capturing particles, from 0.3 microns to several microns. The higher the value, the better. A filter with a MERV 13-16 captures almost 90% of identical particles.

The MERV rating indicates the effectiveness of the filter at trapping E3 particle. These particles are between three and ten microns in size. The best 16x25x1 air filter captures the most of these particles. A filter with a higher MERV rating is more effective than other filters.

EPA particulate matter regulations

Particulate matter regulations of the EPA for air filtering are designed in order to protect people against dangerous air pollutants. The agency sets national ambient quality standards (NAAQS), for particulate material (PM), which includes fine particles (PM2.5), as well as coarse particles (10). The standards are reviewed periodically by the EPA and updated if necessary to ensure they still provide the protection Americans require. According to EPA, PM2.5 concentrations decreased 39 percent between 2000 and 2018, and the average PM10 level fell 31 percent.

Health-based criteria are used to measure PM2.5 emissions. The primary standard protects people’s health and the second protects property and the natural environment. These standards establish acceptable levels of air pollution for each geographic region. Areas that meet the primary standards are considered attainment areas. Areas that don’t meet them will be considered nonattainment. A geographic area can have different attainment or nonattainment levels for different pollutants.

Fabric filters

Fabric filters can be used in many industrial and power generation applications. They can reduce particulate emissions, improve bag life, and lower capital- and operating costs. Fabric filters can be used alone or in combination with multipollutant control equipment. These filters come in both high- and low-ratio options.

Fabric filters are designed to remove particulate matter from a gas stream through a physical barrier mechanism. The fabric traps particles in the gas stream. The accumulated dust cake acts like a secondary filter. The filter is usually a cylindrical fabric bag but can also be a cartridge. These filters are very efficient at collecting dust, with some filters reaching 99 percent.
