About HEPA Filters

hepa filtersIf you need an air purifier for the members of your household or home, then it behooves you to know the different features and types of products that are available on the market. They are not all manufactured the same way. Conversely, the methods in which these appliances perform their functions vary as well. There are about a handful of styles and designs to choose from when it comes to picking the right unit for a room or the entire house. Depending on the individual or collective needs and preferences, one or more units may be needed to reach the desired comfort level while breathing from air purity and cleanliness.

Air purifiers fall into the categories of filters, ionizing purifiers, ozone generators, adsorbents and UV light. Even though one or more types of these machines may sound better and more functional than any of the other systems, each one performs according to an intended design. The science that goes into each design and construction uses incredibly precise engineering and minute units of measure. Filters use a pass and grab process that works by placing a filter next to a venting duct or apparatus. As long as the house in question has air flow, these filters collect a lot of microscopic particles. However, they need to be cleaned fairly regularly. HEPA (high efficient Particulate Air) and UPLA (Ultra-Low Penetration) are the two types of filters.

Ionizing Purifiers, as the names suggests, create ionized particulates and then use a magnetic charge of negative or positive to attract the unsuspecting air pollutants. Employing similar uses of technology as the ionizing purifier, Ozone generators change the molecular makeup of the air. It works around a method of gathering Oxygen atoms together and thereby changing their properties to increase air breathability. Adsorbents may use a number of materials to achieve a reversed osmosis effect when it comes to purifying the air of particulates.

For anyone thinking of choosing either ionizing or ozone generating purifier, a word of caution is in order. More than one reputable government agencies have scientific results from independent studies that say ionizing is an ineffective method for cleaning the air and generating ozone may be actually harmful depending on the inhabitants of an environment. The other three methods of filters, adsorbents and UV light have anecdotal and scientific evidence that supports their functionality.
