What You Should Know About Purifiers This Year

The Usefulness of Air Purifiers It is a shocking fact that the air inside a home is dirtier than the air outside because of the presence of the following pollutants: mold and mold spores, which were created from the existing moisture inside the home; dust particles and bacteria coming from forced-heating and cooling systems; pet fur and dander; if there are smokers in the family, the toxins are into the air; pollen and outdoor allergens can be blown in from outside through the doors and windows and can land on the carpet and upholstery. Now it is clear why people who stay more at home are more prone to allergy or have frequent respiratory difficulties due to the concentration of contaminants inside the home, therefore, the homeowner must find measures to reduce the level of contaminants using an air purifier. Filters, such as air cleaners and HEPA filters; ionizing purifiers; ozone generators; with adsorbents; with UV light – all these are the types of air purifiers. Air purifiers with filters are usually installed into two areas in the house: as part of the heating or cooling system of the home or they are installed between the air return duct and the furnace or placed into the air return vents in every room of the house. Foam, cotton, fiberglass or synthetic fibers are some of the examples of filter materials and choosing among them a denser type of material is effective in catching smaller size air particles. Another type of filter is the High Efficiency Particulate Air (HEPA) filter which is designed for filtering air particles of 0.3 micrometers in size, helpful in filtering out allergens and dust particles. Ionizing purifiers make use of a method called corona discharge which convert air molecules into ions and since the air is neutrally charged, when it passes through the ionizing filter there will be an ionization of air molecules, such that large particles in the air, like dust and contaminants, are more prone to be ionized and will be separated from the rest of the components in the air.

Although similar in principle tot that of the ionizing purifiers, ozone generators differ in the sense that instead of ionizing air molecules, it converts them into ozone, which is a molecule made up of three oxygen atoms, and this, in effect, eliminates some of the oxygen components in the air which may be considered as contaminants; at the same time, manufacturers claim that ozone generators deodorizes and disinfects the air.

Activated charcoal is a common adsorbent material which is installed together with the air purifier to take care of odors, fumes and chemicals, contaminants that are present in the air and because activated charcoal is extremely porous, it is effective in trapping passing air molecules so that large size particles of contaminants are stuck into the adsorbent pores, working effectively into two ways, filtering the contaminants and adsorbing them into the filter at the same time.
