Hepa Air Filter Description

Hepa Air Filter Quick Details

Ultra-HEPA filters or ULPA filters. These can trap up to 99.999 percent of particles 0.3 microns or smaller.
Electrostatic filters. These trap particles using a small static charge, which help the particles stick to the filter.
Electrostatic precipitators. These filters use metal plates or wires to attract particles with an opposite charge. They can often be washed and reused.
Ionization. These filters rely on a small charge that emit a magnetic-like attraction to particles in the air. This type of filtration may release ozone gases and could cause irritation for people with respiratory diseases.

Q:Is air purifier effective?

A:Air Purifiers are proven to be effective in removing up to 99.97% of PM 2.5 particles from the air.Air Purifiers use HEPA filters to remove airborne particles that can trigger allergies and respiratory conditions.

Q:How often do you change the filter of air purifier?

A:every 3-6 months.

Most manufacturer's recommend changing your filter every 3-6 months for optimal performance. It is recommended for allergy and asthma sufferers as well as those who want cleaner air to change their filter every 30-60 days.

Q:What does a HEPA air filter do?
A:It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).

Q:Do HEPA air purifiers help with Covid?
A:When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from COVID-19.

Activated carbon filters are small pieces of carbon, typically in granular or powdered block form, that have been treated to be extremely porous. It is so cavernous, in fact, that just one gram of activated carbon can easily have a surface area of 500m2 or higher. Vast surface area enables these carbon filters to adsorb exponentially more contaminants and allergens than traditional carbon.
Adsorption is a distinct process where organic compounds in the air or water react chemically with the activated carbon, which causes them to stick to the filter. The more porous the activated carbon is, the more contaminants it will capture. These filters are most notably used to remove hazardous compounds in home air purification systems.
