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 outmost. 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.
