Air purifiers are a great way to improve the air quality in your home or office. They use a variety of technologies to remove impurities from the air, such as HEPA, UV, negative ion, ozone, and electrostatic filters. HEPA technology is the most effective at removing particles from the air, while UV technology is best for killing germs. Negative ion air purifiers use chemical injections to clean the air, but they are not as effective as other technologies.
Ozone air purifiers can inhibit the growth of some biological agents, but they are not as effective as HEPA filters. Electrostatic filters use static electricity to filter the air and remove particles. HEPA technology has been proven to be the most effective tool for removing impurities from the air. HEPA filters are accordion-shaped and have a very large surface area for air to be pushed by the air purifying fan.
They trap particles in the air and remove odors, chemicals, and gases that other technologies cannot. In 2000, Hammes produced the first compact air purifier that was proven to reduce allergies and asthma in the home. UV technology is most often used in conjunction with particulate filter systems because it doesn't actually remove particles in the air. Air purifiers using this technology have a UV lamp installed and, as microorganisms pass through the UV rays irradiated by the lamp, cellular or genetic damage occurs, destroying the microorganism.
Without a filter system, too many microorganisms are shaded from light by particles, so most air purifiers that use UV start by filtering the air with HEPA and activated carbon and use UV as the final stage of filtration. Negative ion air purifiers use chemical injections to clean the air. An ion is a naturally occurring particle with a positive or negative charge. They receive this charge by gaining or losing an electron. Negative ions are simply oxygen atoms that have gained an electron.
They magnetically attract airborne particles such as pollen and dust, until the newly formed particle is too heavy to remain in the air. This causes the particle to fall and adhere to another solid element in the room, such as a window or wall. Ozone air purifiers emit ozone into the air which reacts with chemicals found in indoor environments. Many of these chemicals take months or years to react to ozone, making them virtually ineffective. Ozone does not remove particles such as dust and pollen, so most ozone air purifiers also include negative ion technology. Electrostatic filters filter the air using static electricity and have a static charge on the filter to allow particles in the air to adhere to the filter, in the same way that statically charged clothing sticks.
As air quality worsens or worsens in metropolitan cities, electrostatic filters are becoming a necessity for middle-class urban families. Air purifiers using different technologies can help improve your indoor air quality and reduce allergens and hazardous particles. HEPA technology is still considered to be one of the most effective tools for removing impurities from the air, while UV technology is best for killing germs. Negative ion and ozone technologies can help mask polluted air but are not as effective as other technologies. Electrostatic filters use static electricity to filter out particles from the air.
