Noise in Air Purifiers
Jason Uvios
The sale of air purifiers across the United States has skyrocketed over
the past few years. With research showing that indoor air pollution is
2 to 10 times more than outdoor pollution, there are valid reasons for
people to get worried. The only option they now have to deal with the
pollution is to install air purifiers in their homes.
Air purifiers are mainly of two variants - the ionic air purifier and
the HEPA air purifier. The technology in the two are different and so
is the method they work. An ionic air purifier just draws the neutrally
charged particulates to the charged plates inside the purifier. This
technology ensures that there is little or no sound during the
cleansing process.
A HEPA air purifier works on a completely different principle where a
filter is used to collect pollutants from the air. To do so a fan
revolves at high speed to draw in the air form the room and the
pollutants floating in the air gets deposited on the filter. The HEPA
filters are effective for particulates as small as 0.3 microns. It
would make sense here to pint out that the width of human hair is about
100 microns.
However there is a drawback to the HEPA air purifier. While at work the
HEPA ones actually produce some sound which can be annoying for many.
The sound is produced because of the fan inside revolving at high
speed. While for some it would not be too much of a bother, and some
even may actually like the white noise produced, there would be
individuals who will hate a constant buzzing sound.
When you are buying an air purifier you expecting some clean air, and
not a gadget which produces inconsistent noise. You can obviously do
something to tackle this problem. When we buy air purifiers we take a
note of our room size. Now, if we buy a purifier which just has the
capacity to clean our room then we must have it working to its utmost.
This means that fan will always be revolving at the highest speed. The
result would be the noise.
However, if we take a purifier with the capacity of cleaning a 800
square feet room for a room of size 200 square feet, then we can always
have the fan inside the purifier work at low or medium levels. This
will result in less noise. The purifier, all of a sudden will sound
quieter. The only thing that would be of concern is the size of the
purifier might be too big for the room.
