Air purifier reviews: what you need to know


Are you in need of an air purifier for pollen, allergen, smoke, gas or dander? Determine the contaminant you want the air purifier to remove and which meet your health worries. This will assist you in selecting the right system since manufacturers make certain air filters to remove certain contaminants. So read our review and you will know what you need).

The filter efficiency

You can use the particle size that the air purifier captures to measure its efficiency. For example, sizes below 0.3 microns are a better capture sizes for air purifiers. Mold, pollen, dust mites, pet dander and bacteria are usually within the range of 0.5 and 0.3 microns and the best air purifiers can trap the contaminants or things with a size above 0.3 microns.

Air filters with a size of 0.3 microns cannot filter air contaminants like chemical fumes, viruses and cigarette smoke. And if your aim is to remove such contaminants, you should purchase an activated carbon filter, an ultraviolent air cleaner or an ionizer.

Clean air delivery rate

Clean Air Delivery Rate (CADR) is a standardized measurement for the total air volume an air purification system will clean of a particular pollutant within an hour. More efficient units will have a higher number. Another measurement you should possibly consider is Cubic Feet per Minute (CFM). The unit of measurement represents the amount of air that flows through the unit within a minute. Considering the measurement is important because you won’t get the air purifier’s full value if the air purifier unit filters a very small amount of air in a minute. A 350-400 CPM is a very powerful air cleaner.

The noise level

Comprehensive air purifier reviews will help you if you need purifier that will run for 24 hours in a day, the noise consideration is very important since it can become an issue. Manufacturers of air purifiers will list each purifier’s fan speed decibel rating. The following shows the sound air purifiers make depending on the decibel measurement.
