How does the three stage filter work?
First, incoming air encounters a pre-filter that strips away large particles like fuzz, hair, and dust. The prefilter also incorporates activated charcoal to help eliminate odors. Whether it’s pet odor, tobacco smoke, or even not-so-appetizing smells from cooking.
Next, the air leaving the prefilter comes in contact with the purifier’s HEPA filter. This filter is able to stop anything larger than .3 microns. That means nasty stuff like mold spores, pet dander, and pollen are eliminated from the air you will eventually breathe. HEPA filters are so good that more than 99 percent of the pollutants you will find in the air are too large to pass through the filter media. There aren’t many things left to filter after the second stage.
The things that can make it through the first two stages are very limited. If HEPA filters remove 99.97 percent of airborne pollutants; there’s hardly anything left in the air as is enters the filter’s third stage. In the final stage the purifier tackles contaminants smaller than .3 microns like viruses (flu, common cold, etc.) and bacteria (for example E.coli). A UV-C light blasts these airborne pathogens, killing them on contact.
Cleaning and Filter Replacement
This unit is pretty low maintenance thanks to its filter design. According to its owner’s manual a single air filter can last up to six months, but you should take a quick look every two weeks. It also helps to give the filter a quick cleaning with a vacuum during that inspection. Doing so will remove larger particles, but could also reintroduce contaminants into the air if your vacuum does not have an adequate filter.
Circulation and Room Size
The recommended room size for this unit is approximately 155 square feet. However, it is able to cycle just over 100 CFM (cubic feet per minute). If you see the specifications for this air purifier’ that is what the 100+CADR rating is referring to. And, that rating is pretty impressive when you consider that this unit is only 22 inches tall and surprisingly quiet. Set to the fan’s lowest setting the machine barely makes a sound. When you consider these performance metrics and the 4825’s low price, it’s easy to see why this could be the best value air purifier on the market.
