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.

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:
