HEPA Air Purifiers

The HEPA (High Efficiency Particulate Air) air purifiers trap about 99.97% of particles that are even 0.3 microns in size. With this air purifier, what you are not supposed to breathe in is caught by the air purifier. So make sure that the air purifier is original and not a fake and can indeed trap such fine particles as there are many false air purifiers around making false claims of their capabilities.
