Air filters
are becoming common in every household with the increase in air pollution
everywhere around the globe. However, sometimes there are some air filters
which cause problems instead of resolving them. Some air cleaners emit toxic gases
which can impair your memory, damage your lungs and respiratory system, and
also cause cardiac diseases.
In such
cases it is a dilemma to understand which air cleaner would suit your needs and
your home. But, now you do not have to worry. All you have to do is take care
of these few things when you are about to buy a purifier and you will be in
safe hands.
So let us go
ahead and check the characteristics that will bring out the best in the money
that you invest in buying an air cleaner.
Check for
certification
Air cleaners
are supposed to be certified and approved by the Association of Home Appliance
Manufacturers also known as AHAM in short. These certified air cleaners are
then rated between a range of 0- 450 according to the Clean Air Delivery Rate
(CADR) , which indicates the cleaner’s capacity to clean contaminants. The
better the rating, the better the cleaner. This is something to look out for.
Check for ozone
Ionized air
cleaners that use electrically charged plates known as electrostatic
precipitators usually emit ozone gas which can cause irritation to the lungs
and respiratory organs. Hence, it is better not to purchase these air
purifiers.
Check HEPA
HEPA air
filters or High Efficiency Particulate Air filters are highly effective for
cleaning the air of dust particles, pollens, smoke and other contaminants.
These cleaners do not emit ozone and use a filter which needs to be replaced
every once in a year.
Check for size
You need to
know the size of the air filter which will fit the room in which you intend to
keep it. Just carry along with you the dimensions of the room where you want
the air filter kept and match it to the
AHAM certification on the appliance which gives the room size which matches the
air filter.
Check for efficiency
Air filters
are meant to be kept running. Hence they need to be durable and efficient to work
for a longer period of time and to be able to clean more dust and dirt in the
air. An air cleaner’s certification from AHAM will determine the same.
