An air purifier can be termed as an air cleaner. It is equipment that removes the contaminants from the room air. These devices are marketed extensively and they are considered highly beneficial to people suffering from allergies and asthma. Air purifiers reduce or eliminate smoke from cigarettes too. It is manufactured as a large unit and can be combined with air handler and it is also available as a small standalone piece. Air purifiers are also used in industries to remove impurities prior to the beginning of processing. For this purpose, various absorption techniques are used.
Pollen, dust, pet dander, and mold spores are allergens. They cause allergies, especially in people who are sensitive. Smoke particles and volatile organic compounds pose a huge risk to humans too. Exposure to several components makes a person sick. A Levoit air purifier helps to remove these elements and this way reduces the occurrence of diseases. Active and passive technologies are used in these air purifiers. In an active technology, the ionization technique is used to clean the air and on the other hand in a passive unit, filters are used to remove pollutants. These techniques are highly effective as the dust matter and particulate are removed from the air completely.
There are various processes used to purify the air. Some of them are as follows:
- Thermodynamic Sterilization- In this technology, heat sterilization technology is used via a ceramic core having micro capillaries. It removes unwanted materials from the air.
- Ultraviolet Germicidal Irradiation- It is used for sterilization of the air. It is passed through a fan and then through the UV lamps to force the air passing UV light.
- Filter based purification- Here; airborne particles are trapped according to size and thereafter, excluded. Air is forced and particles get captured physically.
- High-efficiency particulate arrest- Almost 99% of dust particles is removed. The filter is installed in a manner so that no air enters into a room without passing via it.
Rating of an air purifier is dependent on several factors. It includes the rate of delivering clean air. This determines how properly air is purified. It is based on the changes of air on an hourly basis and the efficiency at which the area is covered. Costs of replacing filters and energy uses are the other methods to rate a Levoir air purifier. Other factors such as the years the filters will last, the nose produced are considered too.
