5 Common Types of Air Purifiers

5 Common Types of Air Purifiers   Shopping for an air purifier? Below are 5 common types of filters and purifiers that can be used in varying combinations.
  1. HEPA Filter
High Efficiency Particulate Air (HEPA) filter is the most common air purifier. It filters particles as small as 0.3 microns, such as bacteria, chemicals and some viruses. HEPA filters create healthier indoor air since they can trap small organism and do not produce harmful byproducts such as ozone. The more air moves through it, the more it is cleaned and filtered. When it is already filled with blocked particles, air can longer pass through. This is the time that you need to purchase a new one.
  1. Activated Carbon Filter
While HEPA filters are great purifiers of particles, they cannot remove odor and harmful gases off your indoor air. With these gases available, you cannot guarantee a healthy breathable air inside your home.  Activated carbon filter comes with chemically bonded molecular pores which catch pollutants including gases and prevent them from being distributed in the air. However, it also has its limitations including failure to catch very far contaminants and is low efficiency in removing allergens and other airborne particles.
  1. UV Air Purifier
UV air purifiers are low efficient in removing dusts and other airborne particles but perform best in screening viruses and bacteria in the air. As air flows in the air purifier with installed UV lamp, cellular damages kill the microorganisms completely. UV Air purifiers work best with HEPA and activated carbon purifiers.
  1. Negative Ion
Negative ion air purifiers are more modern way of filtering the air. The negative ions attract airborne particles and drop them to a solid object in your home such as your windows and walls. As time passes, these particles are losing hold of the object and eventually circulate back into the air. Basically, negative ions do not purify the air inside.
  1. Ozone Purifiers
Ozone purifiers produce ozone gas which can trigger respiratory issues such as asthma and lung problems. Health professionals do not recommend the use of these purifiers because aside from low purifying performance, it is dangerous to your family’s health. Air purifiers are smart ways to clean your indoor air. However, it also takes smart decisions to choose the right one for your home.
