What is a pocket filter?

The pocket filter is an air filter with pockets used with filtering devices for heating, ventilation and air conditioning (HVAC). Continued to reduce dust in the air, a pocket filter can also take in many other types of particles and must be able to reduce the number of particles by at least 90 percent to sell legally. Two types of material are used for pocket filters: glass fiber and synthetic fiber. The electric charge applied to filter materials helps to collect particles and some are made to avert bacterial growth. In hospitals, the existence of particles may be a problem as they can cause respiratory problems or make it difficult to breathe some sensitive people. Paint cabins and inner areas where they work with paint with paint. For every sensitive person and for business, where particles growing, air filters are used to help people breathe.

There are many types of airH filters and one of them is a pocket filter. This filter is not made to fit into your pocket; Instead, several pockets have added to the metal filter lining. The number of pockets varies according to the size of the manufacturer and the filter, but there are generally three to 12 pockets. USA (EPA) US (EPA) regulations require that pocket filters be able to reduce particles by 90 percent to 95 percent, but many high quality filters decrease even more than this.

For the production of pocket filters, two materials are used: glass fiber or synthetic fiber. The glass fiber was the first used and although the synthetic fiber is considered to be progress, the glass fiber lasts about four times longer than the synthetic. It also has a better efficiency of time, but may be prone to growing and collecting bacteria. Synthetic material has no efficiency or the same longevity over time as glass, but is resistant to bacterial growth, which makes it ideal for hospitals and scientific devices that cannot risk bacteria problemsEMI.

Most pocket filter units have an electric charge. This charge is applied to the material to attract dust and other particles with higher efficiency. The problem of charging synthetic material is that it loses its efficiency faster than if no charge was applied to the handker filter.
