Other Different Types of Air Filters/Purifiers for Home Use

​The quality of the air produced from an air purifier is completely based on the quality of the air filter used in it.

They help in reducing the allergens that are airborne and ensure that pure, clean and fresh air is produced from it all the time. There are in general six different types of air filters that can be used in an air purifier. These are as below:

HEGA Filters: HEGA are the High Efficiency Gas Absorber filters. HEGA filters should exhibit the minimum of 99.9% efficiency. They use the “absorber” filtration for filtering out the gases, chemicals and odors.

The method of the absorber filtration should be adhering to the specific standards in the designing, building, filling and packaging phases. It must remove even irritants like the dust, mold spores, pollen, pet dander and bacteria.

Activated Carbon Filters: These do remove the odors, gases, and the chemical toxins. In this, the carbon or the activated charcoal gets treated with the oxygen for opening up millions of the tiny pores present between carbon atoms.

This activated charcoal does adsorb the odorous substances present in the gases or liquids. Term “adsorbing” refers the way pollutants get attached to charcoal by the process of chemical attraction. Large surface area present on the activated charcoal provides it with thousands of pores that aids in trapping more pollutants.

Electrostatic Filters: These filters do attract pollutants using electrostatic charges for cleaning the air. The electrostatic charges get created by the air pushing through one maze of the prone fibers that are static.

The airborne particles get attracted to static charge and thus get captured in filter while passing through the prone fibers. Only vacuum cleaner for HEPA or hand wash can help in removing the particles from the filter that got captured in it.

Charged Media Filters: These utilize the electrostatic energy. The media filter that is made from the synthetic fibers and it is charged through manufacturing process. It retains charge while the time of usage.

The charge attracts the airborne particles and gives them one electrostatic charge and traps them within fibers of the conventional filter. These filters costs less, are efficient but gets prevents passage of air when it gets soiled. Then the filter has to be replaced.

Systems of Hybrid Air Filtration: The system of Hybrid air filtration maximizes the effectiveness using multiple technologies.

The hybrid air purifiers utilize one combination of the filtration methods (mostly those mentioned above) and each filter used add the overall effectiveness and the quality of air purifier.
