Air Purifier


Air purifiers remove contaminants from the air. It is a generic term for a machine that can remove pollutants from air, and includes air filters and clean air machines.

Polluted air contains solids, liquids, and gases which can affect human health and negatively affect quality of life. Air cleaning systems use a variety of methods to purify the air.

Removing Impurities


An air purifier selectively removes material from the air. This can be achieved with filtering methods, electrostatic means, ultraviolet light, or other procedures. Physically filtering the air is very straightforward. How air filters work is by trapping particles—as air passes between the filter fibers, the particles get stuck in the filter.

Electrostatic air cleaners impart an electric or static charge to the particles in the air. This causes them to be attracted to surfaces which carry the opposite charge, and the charged solid and liquid particles fall out of the air. Ultraviolet light can kill pathogens in the air, but may leave suspended particles in the air.

Combined Power


Removing gaseous contaminants from the air may require special chemical methods. A carbon filter uses activated carbon that is specifically engineered to capture passing pollutants. Simple molecules that make up pure air aren’t as attracted to the surface of the carbon as the longer and more complex chemical pollutants are. This means the pollutants get tangled on the activated carbon while the nitrogen and oxygen molecules easily move along.

An air purifier with carbon filter will pair some method of removing solid pollutants with a carbon filter to remove gaseous and liquid contaminants. For example, the SoClean 3-Stage Air Purifier includes and an activated carbon filter to capture particles and volatile organic compounds

FAQs

HEPA and ULPA rated air purifiers really work, and they work very well. A HEPA filter must remove at least 99.97% of particulate matter 0.3 microns in diameter, and an ULPA filter removes at least 99.999% of particles 0.1 microns in diameter. This means that for every 100,000 particles that enters an ULPA filter unit, only one makes it through.

Air purifiers with HEPA or ULPA filters absolutely reduce dust. The standards for HEPA filters require that at least 99.97% of particulate matter 0.3 microns in diameter is removed from the air by the filter. HEPA filters are actually more effective at removing particulate matter that is both larger and smaller than 0.3 microns. Dust is generally larger than 1 micron, which means an air purifier with a HEPA filter removes over 99.97% of dust in the air.

Air purifiers should be placed either where humans or pets are spending the most time, or near a source of air contaminants. Air filtering works on the air that passes through the filter, so an air filter in a room that is unoccupied isn’t as beneficial as having it next to where occupants are. In situations where there is a steady source of indoor air pollution--for example, from construction or renovations--placing an air purifier near the sources of dust and particles can help to clear them from the air before they circulate to the remainder of the home.

Air purifiers and air filtration systems in general process a certain amount of cubic feet per minute. Manufacturers will often publish recommended room areas for their products. You can find out the volume of air in your room by multiplying the length, width, and height of the room. For example, if a room is ten feet by ten feet with ten-foot ceilings, there are 1,000 cubic feet of air in the room. An air filtration system that can process 100 cubic feet per minute will take ten minutes to process all the air in the room. This means that every hour, the air will pass through the air purifier six times.

No. Air purifiers do not cool the room. The air circulation created by the air purifier may offer the same type of comfort that a fan does. Fans and air purifiers do not cool rooms, but by providing a steady stream of air that evaporates moisture from skin, a person will be cooled by moving air.
