Regardless of whether you are plagued by dust, dog or cat hair, pollen, or dander they are all particles. Any air cleaner that is to be effective has to be able to effectively eliminate a wide range of sizes. Here are 4 filters it should have to be able to get the job done.
Large Particle----This is a money saving filter for any air purifier. It stops big particles with a relatively inexpensive filter. They range in price from $24 to $30 and can be replaced every couple of years to avoid replacing the bigger and more expensive filter, mainly the HEPA.
This type of filter can remove the big particulates you can see such as dust, human and animal hair, as well as pet dander. This allows the HEPA to remain unclogged so that it can remove microscopic particles effectively.
Medium Particle---Designed to remove particulates such as mold and mildew spores and pollen, it can really make a difference in how well those who are allergic or asthmatic feel indoors. Reducing these potent allergens can reduce flare-ups and drastically increase quality of life.
HEPA---Any air cleaner that has any chance of successfully removing airborne particles should use this type of technology. High efficiency particle arresting (HEPA) filters are designated as such because they can remove 99,997 out of every 10,000 airborne particulates that are .3 microns or larger. A micron is defined as one millionth of a meter so it's clear to understand the depth of filtration that this filter makes possible.
Carbon Cloth---This type of filtration was originally developed by the British Military to combat chemical warfare, and its make-up allows it to serve a dual purpose. Because it is made of carbon it is able to remove gaseous pollutants such as smoke, odors, and noxious chemicals. But because it is woven like a cloth, it gives additional protection against particles as well.
Since particles come in all sizes, a purifier should contain a canister of filters that can address the wide range of particles size. Pre-filters are an excellent indication that a purifier will address particles of many sizes and the presence of a HEPA in the canister confirms that it is a serious and effective solution for particle removal.
The last thing to look for is a guarantee on the filter's ability. Any manufacturer who is able to stand behind their filter for years rather than months is an indication of the effectiveness that you can expect from the cleaner.
