An air purifier is an apparatus that eliminates the contaminants from the air in a room. The machine is sold for those who are allergic to dust and also those who suffer from asthmatic attacks. The apparatus is also used in removing second-hand tobacco smoke. The air purifiers that are commercially graded are made are a small stand-alone unit, or they could be formed in a way that it is large and can be fixed to an air handler unit. It can also be affixed to an HVAC unit that is mainly found in the medical and commercial industries. An air purifier could also be used in an industry to clear the impurities such as the carbon dioxide from the air before it is processed. The pressure swing absorbers technique is mainly used in this process.
There is a benefit that is acquired due to this process. One is that the dust, pollen, and mold spore that acts as allergens and causes allergy to sensitive people are eliminated. This creates good condition for that kind of individuals to live. There is also some smoke particles and other highly dangerous organic compounds that are removed using this process. This prevents the threat of some diseases to the human beings. Air purifiers are also capable of capturing a great number of bacteria, virus and DNA particulates that are destructive.

There are several ways of purifying the air. Thermodynamic sterilization is a technology that utilizes heat sterilization through a ceramic core with microcapillaries. It is heated to 200 degrees Celsius. The majority of microbiological particles are eliminated by burning. They include bacteria, virus, mold, and fungus. The air is passed via a ceramic core by a natural process of air convection. It is then cooled by use of heat transfer plates and eventually released. This method is not a way of filtering air because it does not eliminate particles.
Another way of purifying air is by filtering. The process uses filters the airborne particles depending on their sizes. The air is forced through a filter, and the particles are captured by the filter. The HEPA filters eliminate at about 99.97% of the particles, and it works better when the particles are larger.
Ionizer purifiers use charged electrical surfaces so as to produce electrical gas ions from the air. The gas ions are connected to airborne particles that are then electrostatically attached to a charged plate that is meant for collecting them. Read here for air purifier reviews!
