What is an air purifier?
An air purifier helps to take all the pollutants and allergens out of the air you breathe wither at home or in your workplace to make it easier for you to breathe. An air purifier filters out dust, smoke, pollen, pet dander, mold spores and other airborne pollutants as small as 0.3 microns. Through one of these devices, the dirty air is drawn into the device through the inlet grill. Some of the devices have a washable filter that traps the larger particles. Air passes through the filter and helps to reduce the odors along with the particles. Air purifiers come in all shapes and sizes and there are several technologies that they use to clean the air in homes and offices, such as electrostatic precipitation, HEPA filters, ionizers and ultra-violet light.
What are the benefits of using an air purifier?
Having clean air in your home has many benefits:
- You sleep better
- You are more alert
- You don’t have as many allergies
- You have better digestion
- Your immune system will improve
- You will have more energy
- You will be able to breathe easier
- Your skin will be less irritated
What is a HEPA air filter?
A HEPA filter is used in an air purifier to help filter harmful pollutants and allergens out of the air you breathe. This technology was developed by the U.S. Atomic Energy Commission to remove the airborne radioactive particles from the air. In order for a filter to be considered a true HEPA, it has to be able to remove 99.7% of the particles as small as 0.3 microns from the air. HEPA is an acronym for High Efficiency Particulate Air and the filter works by circulating the air to purify it.
How does an air purifier work?
An explanation of how air purifiers work depends on the type of air purifier that you have. Electrostatic, ionizing and ozone air purifiers are all intended for the purpose of cleaning the air, but the process used in each one of them is different. Some air purifiers use ozone to purify the air. Ozone is converted from oxygen through electricity. One oxygen atom splits to oxidize the pollutants and remove them from the air.
What are the different types of air purifiers?
There are different types of air purifiers and each one of works in a different manner. The end result is the same for all of them – clean air for your home or office. Some of the choices include:
HEPA filters. HEPA stands for High Efficiency Particulate Air and it causes air to pass through a specially designed filter. These filters have been proven to be very effective at removing dust, pollen, mold, dust mites, bacteria, and other allergens with a 99% efficiency rate.
Ionic Air Purifiers. These types of air purifiers use three types of technologies to clean the air. They attempt to charge the particles and deposit them either on metal plates or on surfaces in the room. They can be very effective when they are combines with other air-cleaning technologies.
UV Air Purifiers. These devices pass air through intense UV radiation that damages the DNA of most of the particles so they cannot reproduce more particles.
