The Environmental Protection Agency (EPA) has declared that indoor levels of pollution are significantly higher than the air outside. While they recommend the use of air purifiers to improve air quality levels indoors, you know you have a problem if your air purifier can be heard more easily than you.
While most air purifiers claim to be quiet while operating, the fact is that their decibel levels are usually low only at the lowest settings. Therefore, if you use your air purifier at the optimal setting, you might need to find a quieter model.
The best varieties of quiet air purifiers will operate at 15-25 decibels; the noisiest ones at the highest settings will register 65-75 decibels while the average air purifiers at the lowest speeds will register 30-40 decibels.… [ Read More ]
While its ability to purify air is unparalleled, HEPA air filters need to draw air in, filter it and then push it back into circulation. This process produces the noise, which is a byproduct of the speed of the fan.
Ionizers utilize negative ions to attract airborne particles and do not have in-built fans or motors, which keeps them quiet when operational. However, while these purifiers cleanse the air, the pollutants remain on the surface of the room.
Air purifiers that use thermodynamic sterilization systems use heat for incinerating the air pollutants. Hence, they are among the quietest air purifiers. Some of the popular models in this category include BlueAir, Airfree, Honeywell and Whirlpool. [ Minimize ]
