Most Common Questions About Air Purifiers



1. Do I really need an air purifier in my home?
Depends on several factors, including your own comfort level and what
indoor air quality in your home. There are several factors to
account, however.
First, many health organizations agree that indoor air quality
is often worse than the air quality outdoors. In fact, for many people, indoor
allergens and irritants such as dust, smoke and pet dander may be two to five
bad times at home and outdoors!
There are several signs that may benefit from an air purifier
home. Reasons to get an air purifier include:

Symptoms of allergies such as watery eyes and runny nose
Itchy, dry skin or frequent skin rashes
Asthma or other respiratory problems
Being or living with a smoker
Owning indoor pets
The appearance of mold in your home
2. Do all air purifiers clean the same types of air pollutants?
No. Although all air cleaners clean certain particulates from the air, there
differences in what and how to clean. Some remove dust and particles such
as pet dander and smoke very effectively, while others actually deleted
bacteria, viruses and fungi and mold. But very few do all these
things, so be sure to read the article Understanding Air Purifiers for a more
detailed description of what each type can and can not be done to improve air quality
at home.
3. How I can know what size air purifier to get to my house?
In reality, most air purifiers are designed for individual room use rather than
for the entire home. Unless you have an air purifier or air filtration system
is installed in your furnace or air conditioner, you should get
separate units for each room or living space.
The reason you need separate units for each room is because effectiveness is
affected by air flow, and walls mean no air circulation. Each room will have its
unit itself.
To determine the size you need, look for the CADR number. This number indicates
Clean Air Delivery Rate, which must always be equal to at least 2 / 3 of total
square meter room that will use the air purifier in. For example, a
10 'X 12' room has 120 'square feet, and needs a purifier with a CADR number of
at least 80.
4. What is ozone and is safe for indoors?
Ozone gas is a tasteless, colorless, composed of three oxygen atoms. Can be
found in the upper atmosphere and is naturally produced by thunderstorms over
electric shock.
It is perfectly safe if kept within acceptable levels (between 0.02 and 0.05
parts per million), like many other naturally occurring gases
are not detrimental to us at certain levels. Ozone air purifiers have been developed
to produce the right amount of ozone to purify the air without ever
harmful levels.
5. How often do I have to change or clean the filter in my air purifier?
Depends on several factors, including how big the room and what type and
size of air purifier you have. Some will have to be changed or cleaned monthly
others more often.
It is very important to check the filter regularly and follow the recommended
program the manufacturer suggests, since the efficiency of the air purifier
is based on proper maintenance.
6. What exactly is a Micron?
A micron is a measure of the size of particles in the air. A micron is
1 / 25, 400 inches (about 100 times smaller than a single strand of hair).
Obviously, a micron is too small to be seen. For the purpose of choosing a
Air Purifier, most types are considered very effective if you can filter
pollutants in the air to 0.3 microns.
7. How much should I pay for an air purifier?
It is very difficult to determine what to spend on an air purifier because
The price does not always guarantee quality. No doubt, you must be willing to spend
sufficient to obtain a high quality product, but protect your investment, ensuring
your air purifier comes with a warranty.
When buying an air purifier, also take into account the cost of replacement
filters and the electricity to operate.
8. A noisy air purifier?
An air purifier with a fan to be a bit of noise. HEPA filters by
example, have fans to move air through the filter itself, although improved
covered and quieter fans have been developed to reduce noise.
Ionic and units of the ozone layer may not have a fan because they use an electrostatic
charge or ozone, so they are completely silent. If you combine their technology
with a filtration system or a fan to boost air circulation over the plates,
their willingness to be a sound, but this will be minimal and these fans may be closed
when you want.
In general, the noise level up to an air purifier with a fan is low enough
that is not intrusive.
9. What rooms should I put an air purifier?
The rooms you use most often are the most important rooms for the use of air purifier.
Your living room as a living room or hall, you must have an air filter,
especially if you have allergies or pets that are in the room regularly, or if
Someone in your household smoke.
The rooms are also a good idea, and that allergies and irritants can disturb our
sleep. Clean, fresh air has been shown to produce a more restful sleep and reduce
breathing problems during sleep at night as congestion, post-nasal drip
nocturnal cough.
Finally, consider getting an air purifier in the bathroom, where odors, mold and
mildew are likely to stay. An air filter here can not only make it cooler
and more pleasant, but reducing the amount of mold in the air for
your bathroom will be less of a breeding ground for germs.
10. Where in each room should have my air purifier is?
For any air purifier, is more important for its location near the most activity
or the flow of traffic so there is plenty of air space around
filter. This will increase the rate of exchange of air and air cleaning
efficient.
With a HEPA filter, it is best to place it near an open area to ensure air
moving around. For an ozone air purifier, you should try to locate the drive
higher rather than lower, since ozone molecules are heavier than oxygen and
tend to move downward. The same logic applies to ionic air purifiers, which
the release of charged particles in the air.
If your air purifier unit is relatively portable and you have someone in
room is a heavy smoker, move the air cleaner a little more about him if
this practical (and death if not offended!). You may also want, in
opportunity to move the air purifier in a specific room when you have a special
get rid of the smell (recorded dinner, etc.).
