Unlike air purifiers, which filter or otherwise trap particles within an air circulator, air sanitizers act on airborne microorganisms in open interior air space. A sneeze - or cough -generated pathogenic aerosol will take significant time to be treated by a circulating air purifier simply because air circulators are unable to treat all air in ...
An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics , and at reducing or eliminating second-hand tobacco smoke .
VHP is produced from a solution of liquid H 2 O 2 and water, by generators specifically designed for the purpose. These generators initially dehumidify the ambient air, then produce VHP by passing aqueous hydrogen peroxide over a vaporizer, and circulate the vapor at a programmed concentration in the air, typically from 140 ppm to 1400 ppm, depending on the infectious agent to be cleared.

One of tallest (nearly 24 inches) and heaviest (17.5 pounds) air purifiers tested, the Winix 5500-2 Air Purifier is ideal for small-to-medium rooms (up to 360 square feet), with a True HEPA filter ...
Dosages for a 90% kill rate of most bacteria and viruses range between 2,000 and 8,000 μJ/cm 2. Larger parasites such as Cryptosporidium require a lower dose for inactivation. As a result, US EPA has accepted UV disinfection as a method for drinking water plants to obtain Cryptosporidium , Giardia or virus inactivation credits.
Air ioniser and purifier with its dust collection plates removed. Air ionisers are used in air purifiers to remove particles from air. [3] Airborne particles become charged as they attract charged ions from the ioniser by electrostatic attraction. The particles in turn are then attracted to any nearby earthed (grounded) conductors, either ...
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.

Subsequent to this, the anthelmintic activity was isolated and identified as a family of closely related compounds. The compounds were finally characterized and the novel species that produced them were described by a team at Merck in 1978, and named Streptomyces avermitilis (with the adjective probably intended to mean that it kills worms).
