Many dangerous substances can be present in and around a room. They may include microbes such as viruses or bacteria. Certain odors of cigarette smoke, pets, and others might be present in a room. Some other particulate materials include dust, pollen, allergens, and smoke particles. All these may cause some health problems. Air purifiers are used to trap these materials. Various types of air purifiers are in use including ozone air purifiers, HEPA filter air purifiers, carbon air purifiers, ionic air purifiers, and ultraviolet air purifiers. Many advantages are associated with the use of air purifiers.
Any allergens in the room can be trapped by air purifiers which improves the health of an individual. The number of dust particles and other lung irritants are also trapped by air purifiers. So it is also beneficial for asthma patients to use air purifiers in their room.
