What kind of air purifier filters are there?
Air purifier filters are an essential component of
air purifiers.
They are the part of the air purifier that sieve unwanted air pollutants
and harmful materials in the air. As indoor air pollution belongs to the
top 5 environmental health risks, it is wise to have solutions to this
problem.
Best Solutions for Air Pollutants
The best way to solve the air pollutants issue is to control or reduce the sources of pollutants, and to ventilate a home with clean outdoor air. However, the ventilation is not at all time efficient for two reasons: the changing weather conditions and the extremely high level of air pollutants.
Room Air purifiers and air cleaners are devices designed
for the reduction of harmful air pollutants regardless of the weather
conditions. There are air purifiers that are mounted on the ductwork of
a home’s central heating, air-conditioning and ventilating systems.
Types of Air Filters
Air cleaners come in variety. There are room air purifiers that use filter in cleaning the air. There are also non-filter types. Air Purifier filters come in several types depending on the type of pollutants removed.
When it comes to air particles, there are two types
of air filters. These are the mechanical air filters and electronic air
filters. A mechanical air filter removes particles by catching them on
filter materials. To this type belong the High Efficiency Particulate
Air filters or HEPA.
HEPA
HEPA filters are known for proven filtration. They
continue to be improved by most manufacturers. HEPA filtration guarantees
that air purifier traps 99.9% of particles larger than 0.3 microns. This
type of Air purifier filters are needed to capture smaller particles such
as smoke, dust, chemicals, asbestos and more.
Electronic Air Cleaners
The electronic air cleaners like the electrostatic
precipitators use electrostatic attraction, a procedure to trap charged
particles. The charged particles accumulate on a series of flat plates
labeled as a collector, and is oppositely charged.
Gas-phase Air Filters
There are Air purifier filters designed to remove gaseous air pollutants. Gas-phase air filters remove odors and gases with a sorbent—like the activated carbon—which absorbs the air pollutants. This type of air purifier filters are exclusive to specific pollutants and do not remove those which are not assigned to them.
For example, carbon monoxide, a dangerous gaseous
pollutant produced whenever charcoal, wood, oil, gas or kerosene is burned,
is not readily caught by gas-phase air filters. Gas-phase may remove some
of air pollutants; however, it is not on regular basis.
