Air Filters
Q1. Do installation of air filters help in
asthma?
Ans. Some health organizations and associations recommend air
filtration. According to them, controlling the sources of allergy-causing
pollution and ventilation can help in asthma. Researches don't agree on
whether or not air filters give added relief from asthma in well ventilated
and clean home. However air filters can help in controlling the causes of
asthma, but they can't be a solution to your allergy problems. A lot of
allergenic particles reside on surfaces like rugs, furniture and counter
tops than suspended in household air. In that case the air filters can't
help in any way.Q. What points should be kept in mind before buying an air
filter?
Q2. What points should be kept in mind before
buying an air filter?
Ans. Before purchasing an air filter, there are certain points which
should be seriously considered so that you may get the efficient and
appropriate filters suiting your requirements.
- The most important point is that you should know what substances the
filter removes and what it doesn't. It helps you in selecting filter of
your choice.
- You should also know the efficiency rating of the purifier.
- The choice of the filter should be according to the size of your
room.
- Another important thing is that the filter is easily replaceable or
not. How much the filter cost and how frequent does it have to be
changed?
- You should also check out that how much noise it creates during the
operation? Is the sound quiet enough to sleep comfortably?
Q3. What are the common causes that create
indoor air quality-related problems?
Ans. The common problems that are responsible for poor indoor air
quality are:
- Inappropriate ventilation
- Maintenance
- Irregular cleaning of surrounding
- Chemical contaminants from indoor and outdoor sources
- Biological contaminants
Q4. What type of contaminants Ozone
Air Purifier remove?
Ans. Ozone air purifiers remove indoor pollution, mold sources,
allergens, and other substances creating respiratory problems. They also
effectively control air contaminants like pathogens, bacteria, viruses,
germs, bad odor, and formaldehyde
Q5. Is it safe to use ozone air purifiers for
filtering indoor air?
Ans. Ozone is a highly reactive form of oxygen and cause irritation
in eyes, nose, throat, and lungs. It is a primary constituent of smog. The
use of ozone purifiers at residential level is not safe if its use exceeds a
certain level. The maximum safe residential level is 0.05 parts per million
(PPM) and occupational exposure at 0.10 PPM for short periods. Its use can
create serious threats for asthma sufferers. Apart from that, infants,
children, and older people are more sensitive to ozone.
Q6. What are electrostatic precipitators?
Ans. Electrostatic precipitators are also called electronic filters.
They create electrostatic charges to attract pollutants and trap them on
collector plates. Their main advantage is that the collector plates can be
easily washed in the dishwasher and never have to be replaced. However if
the collection plates are not cleaned regularly they quickly lose
efficiency.
