Air is a free component that can be inhaled from the atmosphere. But with rising pollution, the atmosphere is filled with harmful components that affect normal living. Allergens like dust, pollen and smoke cause various diseases infecting the respiratory system, the lungs and the heart. Bad odor and chemicals are other pollutants that keep the air infected. That is why man is constantly on the lookout for some clean, fresh air. It is also the reason for the emergence of air purifier as an important home appliance.
Common Types of Purifiers
Purifiers come in different types of sizes and shapes as well as in various colors. Each type of purifier works with different technology to help supply fresh air into the atmosphere. With needs being many, you have to choose the right type of purifier that will suit each individual.
HEPA is High Efficiency Particulate Air, which uses various filters to clean the air. HEPA uses technology that traps all particles less than 0.3 microns. This includes all particles like chemicals, viruses and bacteria. This HEPA filter has a large surface area which the air has to pass through. This helps to purify the air. As it uses surface area to clean the air passing through it, it does not create any side effects that may harm human beings.
UV Technology helps to kill germs like virus and bacteria. However it does not rid the atmosphere of airborne particles. Hence it is used as the last filter in the multi filter purifier. The UV lamp used in this filter should be carefully monitored as well as replaced whenever necessary.
Activated Carbon or charcoal technology provides porous and huge surface area to absorb dust, smoke from tobacco, bad odor and other chemical bonding. It removes all components that pass through this filter.
Negative Ion uses chemical injections to purify the air. It works on the principle of magnetically attracting micro pollutants like dust and pollen. But this technology cannot absorb harmful components present in the air.
Ozone Purifier helps to prevent growth of viruses and bacteria, but it does not clean the air from dust and pollen. However ozone purifiers do not confine to standards of public health.
Choosing an Apt Purifier
Air purifiers have various special characteristics. The speed setter helps to control the speed of the home air purifier. Choosing a purifier that fits aptly into the room should be chosen. A small room requires a small capacity purifier while a large room can use a larger purifier. As these purifiers are portable and used anywhere as they are handy, choose a purifier that can fit into all rooms. The electronic filters are monitored by special monitors which gives a signal when the filter has to be changed.
The automatic operating control helps to control the purifier automatically. The and remote control can also be made used of to help regulate the purifier. The ultraviolet bulb and ion generators will have to be maintained properly and changed regularly.
