Air purifier tips

Air purifiers are basically classified due to the method used to eliminate various sized particles and/or gases from the air. The types of techniques available for use in air purifiers include mechanical filters, electronic air cleaners, and hybrid filters for the elimination of particles, and gas phase filters to control odors. There are also air purifiers which produce ozone in order to remove various airborne pollutants. The selection of a type of an air filter depends on the intended use of the air purifier. There are wide applications of an air filter. Air filters are applied in order to protect the HVAC equipment and components, to protect the furnishings decor of inhabited spaces, to reduce housekeeping and building maintenance, to decrease heating equipment fire hazards, and protect the general well-being of residents. The low effective filters in central HVAC systems can be used in order to accomplish most of these requirements. However, to improve the health of residents higher efficiency filters are needed.

Air purifiers mainly consist of an air filter and a fan or a motor. An air filter is used to clean the air from various airborne particles, such as mold, bacteria, viruses, dust, cigarette smoke, pollen and many others. It also helps to neutralize odors and gases in the indoor areas, whereas a fan or a motor makes the air flow into a filter, which can then capture dangerous pollutants and clean the air. Even more, a fan or a motor returns a cleaned, healthy air into the environment and hence is an important part of an air purifier.

However, a loaded fan produces noise. The noise level is one of the characteristics that describe a certain air purifier. Generally, the noise level of an air cleaning device depends upon the type and size of an air purifier. In addition, the noise level depends also on the quality of an air purifier and an air filter.

An air purifier is a device used to clean the air from airborne particles, such as dust, mold, pollen, bacteria and viruses, as well as to neutralize indoor odors and gases. The effectiveness of air purifiers depends on the cleaning method used in a device and the size of an air filter. The most effective air cleaners have a high filtration surface area, low resistance to airflow and a reduced pressure drop.

However, this type of an air purifier cannot be installed into residential HVAC devices due to its large size but is available to customers in a portable form. Different manufacturers offer a various range of air purifiers, from simple flat mechanical filters to HEPA air purifiers . Most of these devices are available in both portable and non-portable forms. If an air purifier is a non-portable one, it should be installed into a residential HVAC system. They can be also placed in the ceilings, walls or floors of the buildings. These non-portable air cleaners are mostly used for commercial purposes to clean up the indoor air in medical, pharmaceutical, military, food industry and other objects.

The effectiveness of an air purifier depends on a filtration surface area, resistance to airflow and a reduced pressure drop as well as on the volume of air being filtered. The volume of air filtered depends on the size of an air purifier. The size of a room should match a purifier‘s capacity to clean the amount of air in the room. Therefore the size of a coverage area should match the capacity of an air cleaning device. The most effective air filters , called HEPA, come in a non-portable form. They are very large in size and hence cannot be installed into residential HVAC systems. Since they are so big in size, they have a great capacity in cleaning the indoor air and hence can be used in large commercial areas. However, this type of air filters is also available in a portable form and then their size should be considered before choosing them.
