One thing that a lot of people are concerned about is the quality of the air in their home. That’s why air filters are such a big seller. Unfortunately, there are a lot to choose from. So how do you choose which one is best for you? Below are the four main types of air filters and their pros and cons.
The technology for these air filters was developed originally during WWII for removing the dust particles that were radioactive from air to protect the respiratory systems of soldiers. These days they’re often used for filtering air in a house and they can trap 99.97% of those airborne particles as the size of 0.3 microns as well as 95% of those particles as small as 0.1 microns.
When someone inhales air contaminants, the natural defense of the human body is a lot more vulnerable to the particles under 0.5 microns. That’s the reason why these types of filters are recommended by doctors and allergists – they can remove most air contaminants even when they are extremely tiny.
Some common contaminants in the air and their micron size:
