What is the air cleaner?
Air cleaner is any device used to remove molds, cigarette smoke, dust, pet and other pollutants and allergens from the air. The most popular type of air purifier for home use is high -efficiency filters (HEPA). HEPA is first used during World War II to capture radioactive dust and physically cleanse air by "catching" bacteria and pollutants when air passes through them. To make HEPA filters efficient, all air inside the room or building must enter the filter.
In the US, HEPA filters are regulated by the US Department of Energy. Any products marked as "hepa-type" or "99% hepa" do not meet this requirement and should be purchased carefully if at all. HEPA filters
cannot remove gases, odors or viruses from the air, but there are other types of cleaners that can remove these smaller molecules. For example, ionizing cleaners release electrically charged ions that connect toWe pollute the magnets. Depending on the device, these ions may be loosening liquid or gas. Liquid ions simply absorb pollutors, while the gas ions remove pollutants by taking them on a charged board inside the air purifier to "destroy" them. In this type of cleaner, there are no cost to replace the filter, as most can simply be erased with soapy water or cleaned with a vacuum connection.
activated carbon filters can also be used to filter harmful gases or odors. These air cleaning filters are made of coal treated with oxygen. This process creates millions of small pores that absorb gases and odors like a sponge. This is because of this absorption that the replacement of the filter is necessary to maintain efficiency.
There is also a process called photocatalytic oxidation that can be used next to the HEPA filter for betteru steriluize air. In this process, ultraviolet (UV) beams are used to kill all viruses or bacteria that have not been captured.
One last type of air purifier is the ozone generator. Ozone generators release very high oxygen levels to sterilize space from harmful toxins caused by serious problems with mold, mold and bacteria. This is considered to be a "shock treatment" and is usually carried out commercially and in uninhabited spaces.
Several things that need to be considered when buying air purifiers include space, cost, noise and ozone. The larger the room, the larger the filter surface. As a result, you will have to give a larger area of the cleaner.
Of course, costs will be the main problem when buying air purifier. Installing the air purifier HEPA in the HVAC system can be for some expenses, but not for others. In addition to installing or initial purchase, consider the persistent filter replacement costs.
M factor is noise. Air cleaners are available both for fans and without. Choosing a quieter model without fans will mean giving up some efficiency, as fans will cause air to circulate and filter faster.
In the end, ozone should be considered. Ozone is three oxygen molecules (o 3 ) and is a harmful pollutant. It can be toxic when it is produced in large quantities, and while most air purifiers only produce trace quantities, it can only be checked in case.
