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.
Air purifier purpose
Customers who suffer from asthma, allergies and other respiratory system disorders choose air purifiers which are installed into residential HVAC systems and are non-portable. This allows a higher efficiency in cleaning the indoor air from various pollutants and keep the air quality up to the one recommended by official health organizations. People, who are aware of how polluted the indoor air is and who care about their health, also choose air purifiers in order to improve the quality of indoor air in private houses. This is usually accomplished by portable air purifying facilities. When one has a portable air purifier at home there is a major question: „Where should be a portable air purifier placed in a room?” Most manufacturers recommend the best places for air purifiers in a room in the instructions attached to an air purifier. This makes life of a customer a lot easier. Nonetheless, it is important for a person, who is about to buy an air purifier, to find out a proper placement for an air cleaning device.
Where to place an air purifier
A proper placement provides a higher efficiency of an air purifier and hence the quality of the indoor air increases. If a specific pollutant source exists, an air purifier should be placed near to it to assure the best filtration of the most polluted air. A close placement of an air purifier to the existing pollutant source assures best control of its emissions and nearly removes the source. If there is no such source, an air purifier can be placed wherever it is convenient to a customer. There are only a few directions that a customer should follow in order to achieve best results in air cleaning. An air purifier should be placed across the room from an air conditioning or heating device. It should be also placed further from the vent if one exists. Airflow should not be blocked by any obstacles such as walls or furniture. Therefore one should not place furniture or any other objects directly in front of an air purifier.
Additionally, an air purifier should not be placed directly at the wall. The distance between the wall and the air purifier should be at least 8 inches. If one intends to use an air cleaning device in a bedroom, then such an air purifier should be placed more than a meter of distance away from a bedside. This should be done to avoid health problems. In addition, air purifiers also emit a certain noise level ; therefore it is better to place them away from the bedside for a customer’s silent sleep. Finally, air purifiers should not be placed by an open window since doing so may reduce their cleaning efficiency. Customers should know that an air purifier is needed in every room to reach a high quality of indoor air inside the house. It is recommended that people follow the instructions provided by manufacturers since a proper placement of an air purifier may vary with a type and model of an air cleaning device.
