Air ionisers have been used to eliminate the occurrence of air-borne bacterial infections and to reduce static electricity buildup in electronics. Air ionisers are used in air purifiers to remove particles from air. Airborne particles are attracted to the electrode in an effect similar to static electricity. These ions are de-ionised by seeking earthed conductors, such as walls and ceilings.
Ionisers are distinct from ozone generators, although both devices operate in a similar way. At concentrations that do not exceed public health standards, ozone has been found to have little potential to remove indoor air contaminants. At high concentrations ozone can be toxic to air-borne bacteria, and may destroy or kill these sometimes infectious organisms. A number of studies have been carried out on negative ion generators. A study shows that the ozone generated can exceed guidelines in small, non ventilated areas.
Consumer Reports, a non-profit US-based product-testing magazine, reported in October 2003 that air ionisers do not perform to high enough standards compared to conventional HEPA filters. The exception was a combination unit that used a fan to move air while ionizing it. The United States District Court for the Northern District of California dismissed the case, reasoning that The Sharper Image had failed to demonstrate that it could prove any of the statements made by Consumer Reports were false. Air ionisers are often used in places where work is done involving static-electricity-sensitive electronic components, to eliminate the build-up of static charges on non-conductors.

Although there is no clear-cut medical proof that the use of an air purifier alone can relieve respiratory symptoms, some consumers believe they are still a worthwhile purchase. Air purifiers are designed to filter the air inside a room by removing any dust, pet dander, mold, pollen or other harmful pollutants that can cause respiratory problems. However, there are few scientific tests that objectively evaluate the effectiveness of air purifiers and the claims made in marketing such products.
Consumer Reports is one organization that has sought to objectively test the effectiveness of select air purifier models. However, some of their test procedures have come under fire from a few companies in the air purifier industry, an industry expert, and a subscriber who had poor results with CR recommended air purifiers. This Air Purifier Guide Special Report seeks to help you understand the pros and cons of Consumer Reports’ air purification rating system. By providing non-biased reviews, they hope to guide buyers to the best products available in the market. Inside this controlled environment, usually a room or chamber, a tester introduces different outside variables that will eventually interact with the selected air purifier. A special system is also installed inside this room that will inject dust into the air, as well as smoke produced by a cigarette. Consumer Reports video on buying an air purifier and a few brief comments on testing.
400 mobile hospital air purifier is a modular self contained filter housing, the breadth of Biological Controls’ product line provides many products that effectively address these issues. UV has proven to be effective in reducing and eliminating microorganisms; the 254 nm wavelength has proven effective in killing most types of airborne bacteria and viruses. If the air is discharged into the room, tB of the lungs or airways can spread the disease by coughing and sneezing.
