7 Tips for Buying the Best Air Purifier


Respiratory problems such as asthma and allergy are in a rise all over America. Some of the problems are due to personal physical condition, while others may result from the severe air pollutions in some areas. Under this circumstances, people begin to use and trust air purifiers, hoping to get an improved air condition in their households. However, there are too many air purifying products, which makes it difficult to choose the best one for your family. Today we prepare some tips to help you make your decision on which is the best air purifier to buy.


1.  The first thing to consider is which room you are going to place the air purifier as well as the type of traffic and activities in the room.

This is important because you need to know how powerful the purifier should be to effectively accomplish the job. Take five minutes to measure the length and width of the room or figure out the area from the blueprint of your house. After you decide which room to purify, you should also know the kind of traffic and what activities happen inside. This gives you an idea about the capacity of the air purifier. You should buy one that has a little more extra capacity than your room demands, but no less.


2.  The next thing you should know is the kind of use for the room.

This is important because you will need to decide what kind of filter is needed. For example, if there are people smoking in the room, then you should buy a purifier with activated carbon filter so that the cigarette smoke can be absorbed. Also, if you have a pet in your house, then the dander from the pet will be effectively tackled with a HEPA filter.


3.  Figure out the CADR value of the air purifier.

CADR is short for clean air delivery rate, which indicates the maximum square footage recommended in which to use the filter and how quickly if can remove the pollutants. The higher the value, the faster it can filters the air (not necessarily the more thoroughly). You can compare the values with the size of your room and get a basic idea.

4.  You should also consider the noise level of the purifier.

Different types of air purifier may behave differently in terms of noise. For instance, a HEPA purifier is normally annoying and noisy and not good when you plan to place it in the living room or bedroom. On the contrary, the ionizer models are quite quiet.


5.  If you are considering an ionizer air purifier, you should know that it is a must to use it in conjunction with a vacuum cleaner.

This is because sometimes bigger particles can remain suspended in the air and the air purifier is not effective all the time.


6.  Look at the time duration of replacing the filter.

You should check out how often you should replace the filter that comes with the air purifier. The filters can be costly, and replacing it for every 6 months may not be the thing you want to do. Ionizers don’t require filter replacement; instead, you need to clean them on a regular basis.


7.  Look for “Asthma and Allergy Friendly” certificate and avoid ozone.

“Asthma and Allergy Friendly” is a relatively new certification from Asthma and Allergy Foundation. Only a few models have earned this by far and they can reduce allergens. In addition, you should avoid the air purifiers that generate ozone, which is a well-known lung irritant.
