Air Purifier Filters - What Are the Types and Why Are They Important?

An air purifier is a portable device that removes impurities from the air within a room to enhance indoor air quality, thus improving indoor air health. These portable devices are also commonly sold as being helpful to asthma and allergy sufferers and also in reducing or removing second hand cigarette smoke. These purifiers work by forcing cool, dry air through a filter that filters out dust, pollen, mold spores, bacteria, viruses, smog, and more particles from the air. The filter is usually made of activated carbon, ionic, or photo electrostatic filters. Purifiers come in many forms and types such as single room portable, whole house, high output filter stack, or even whole house humidifiers. Each of these designs has its own unique advantages and features.

Single room portable air purifiers are quite effective in removing particles such as dust, pollen, mold, mites, dirt, and smoke particles from the air. It can remove up to 99% of the particles that smaller HEPA filter cannot. With a single room portable air purifier, there is no need to clean the room very often. They can be used to filter the air indoors for up to six months straight. These portable units have filters that are easily changed by simply removing the cover plate, replacing with new one, and replacing the filter again.

Air purifier consists of a high efficiency particulate air filter, and an air flow sensor. When air particles are breathed in by the person with an allergy or asthma, the sensor will trigger the filter to release a filter cloud. The cloud is then collected by the ionic/photo electrostatic filters that are found in each purifier. A purifier's EPA ratings are determined by the HAPs (High Efficiency Particulate Air) and the MTBS (MOisture Gas Behavior).

An air purifier can clean the air inside your home, office or other enclosed space by using one or more of its many filtering systems. There are three main types of purifiers. Filters are considered to be the best type of air purifier because of their ability to trap more particles than any other kind of air purifier. Air purifier works by allowing only a fraction of pollutants into the air, thus keeping allergens and bacteria from being circulated through the home or workplace.

A third option is a multi-stage air purifier, which is a bit more expensive but produces better overall air quality. A multi-stage system uses a combination of technologies to achieve higher efficiencies in filtering. The most commonly used technology by manufacturers of the triple combination air purifiers is called the ozone chamber. Ozone chambers are equipped with an activated carbon filter, a high efficiency ion exchange filter and a high temperature anti-ultraviolet lamp. This combination allows for the most efficient filtration possible without having to sacrifice the high output of purified ozone.

An air purifier that is specifically designed to remove petrochemicals, herbicides and pesticides can also be considered to meet your purification needs. A complete system that meets your specific needs should be purchased. A good way to start searching is by looking for a list of the most common chemicals that need to be removed in an air purifier and an analysis of the technologies needed for each type of purification. Purchasing the right purification technology will ensure that you enjoy excellent indoor air quality as well as protect your health and the environment.
