carbon Air Purifier pleated Pre-Filter

A pre-filter is an air filter that removes large particles like dust, dirt, and hair. Pre-filters are the first step in the air filtration process on an air purifier. A pre-filter protects the main air filters from getting clogged up with debris so they can trap microscopic pollutants.

Primary filtration of air conditioning system, coarse filtration of clean returning air system.most used in air purifying equipment that is installed in homes, commercial buildings, transports, and public areas.

A pre-filter is an essential part of an air purifier because it sieves large particles that can impede or shorten the life of the filtration system. A pre-filter is good to have because it protects the main internal filters from damage.It works by collecting large particles before they enter the air purifier unit. Pre-filter air filters work in a similar manner to a sieve. Air flows through the small pores or netting of the pre-filter while dust, dirt, and hair get trapped on the surface of the pre-filter.
There are two types of pre-filters: mesh and carbon. A mesh pre-filter only traps solid particles. A carbon filter traps both solid particles and gaseous pollutants. The type of pre-filter used in an air purifier will depend on the other types of internal filters.

A mesh pre-filter air filter is similar to a sieve. It is made up of small pores or netting that allow air to flow through but stops large particles like dust, dirt, hair, and other debris. The sole purpose of a mesh pre-filter is to trap large contaminants before they enter the air purifier unit.
A carbon filter air filter is a more advanced type of pre-filter. It is made up of activated carbon material that is in either powered, granular, or honeycomb form. An activated carbon air filter will do two things: stop large particles from entering the air purifier and trap gaseous pollutants like chemical vapors, volatile organic compounds (VOCs), and odor molecules. This leads to cleaner air that has fewer toxins and smells fresher.
