HEPA (High Efficiency Particulate Air) air filters are the most powerful air filters for your home. These purifiers were originally designed to filter radioactive contaminants from the air of Manhattan which should tell you how powerful these machines are. Modern HEPA filters are smaller in size and are easy to install and use.
Apart from the standard filtration, they also often have pre-filters that capture and filter larger dust and dirt particles that can damage the HEPA filters. Then the air is rid of different pathogens, contaminants, gaseous materials, odor or other particulate impurities. As per the US law, a HEPA filter must be able to remove at least 99.7 percent of all
particles that are greater than 0.3 mm in size.
If you live in an industrial or polluted area where clean air is scarce then HEPA filters are highly recommended. They can also be used in homes where people suffer from airborne diseases or allergies regularly. If you are ready to buy one, always buy a device with larger filter as those can remove more pollutants than their compatriots. Visit http://www.airreflect.com/hepa-air-purifiers/ now to learn more.
