How to choose an air purifier ?

    How to choose an air purifier? I believe It is not a small problem to the people who plan to buy one, as choosing an air purifier is a tough and huge project indeed. With the development of the new air cleaning technologies, countless air purifiers or other air cleaning machines are flooding to the market. Various technologies, covering different price range, different shapes and sizes, makes the choosing process is very complicated and difficult to make decision. Well, as a housewife who has used 3 air purifiers with 8 years history, I would like to share some tips that in my mind which is deserved to be called “tips”.

    1. “HEPA” air purifier is better. HEPA is short for High Efficiency Particulate Air, which is a standard made by Energy department of United States of America. To be labeled with HEPA, the air cleaning device need to be able to remove over 99.97 percent of indoor airborne contaminants at a size as small as 0.3 microns.

    2. Ozone kind is not recommended if you have other options. Ozone has a great effect as an oxidant, which is often used in air purifier to remove odors and chemical pollutants. Well, on the other way, the Ozone has some potential effect on human health, it is severer to some asthma suffers and allergy suffers.

     3. Read some air purifier reviews. Why we need to check some air purifier reviews? The reviews are from the previous buyers directly, so they are mostly much more detailed and practical. Well, of course, at the same time it is much too subjective to a certain degree. Try to read more reviews of air purifiers, good reviews, bad reviews, persona reviews, professional reviews from some reviews website.

     4. Warranty is a stuff you need to consider. We often overlook the warranty issue as we take it for granted that our air cleaning machines could be used for many years. To be sad, not matter how good the air purifier works at the beginning, no one could promise it will suddenly goes wrong without any notice. And different manufacturer of air cleaning machine have various warranty policy, some support as long as 5 years after-sale service, meanwhile, some brands support warranty of only 1 year. As to the detailed warranty items, there are also many limitations, Pay attention to it. Recently, I am gathering some air purifier guides websites, and some best air purifier models information, I have got some really useful marketing information. The best air purifier list in the views of warranty is recommended if you could like to know more.

    5. Ignore the air purifiers under 50$. Well, one thing is definite, no manufacturer will produce a produce with a too cheap devices with a unbelievable cheap price. I am not saying the more expensive the better, but, just try to choose one in a reasonable price range.

    Nowadays, more and more people begin to know that air pollution is a main issue related with allergies and some respiratory diseases.

Beyond your thinking, the household environment much more contaminants. Dusts and hairs are the among the common pollutants, if you have pets, then you have danders and mold inside without a doubt.

    As the indoor pollutants are in varied forms, the room air purifiers have different technologies to target the pollutants. But they are effective to some kinds air pollutants, to others, may not.

On todays’ market, there exists 5 main technologies to clean air, namely, Activated Carbon Filter, HEPA Filter, Ionic technology, Ultraviolet technology and Ozone technology.

    Activated Carbon Filter has effect in removing Odors, kitchen smoke, gases and fumes, it has good performance to help you filtering the unpleasant smells.

But then, coming to dust, micro-organisms and allergens, Activated Carbon Filter does not work well. And you need to replace or wash the filter when it is full.

    HEPA filter works very well in capturing pollen, spores, mold, dust, hair and some bacteria. The real HEPA filter could remove 99.97% of all pollutants as tiny as 0.3 microns in size.

The disadvantages are this technology not effective to odors, gases and viruses. In addition, HEPA filter is a little expensive and you need to replace it after around 12 to 18 months. Some HEPA filters could be vacuumed and be used again and some are not.

    The ionic technology air purifiers are good at removing viruses, bacteria and smoke, causing them clump together and fall to the collecting plate or the ground. The weak side is that they do not work to odors, chemicals, and they could not kill germs, and common viruses.

    The Ultraviolet is the most effect method in killing micro-organisms, such as viruses, Bacteria, pathogens. While on the other hand, it does not work on gases or odors, and allergens. And the bulb need to be replaced annually.

    Ozone air purifier has strong function in filtering odors, cigarette smoke, and destroying some kinds of chemicals and bacteria. But, on the opposite side, Ozone is smelly to some people. And according to some experts, Ozone has bad influence in peoples’ throat and respiratory diseases patients.

    So, as you can see, we have so many air cleaning technologies, but none of them solve all the air polluting problems in one stop.

When we choosing air purifiers we need to do some research and get clear which air pollutants rank the first place that we need to handle with.
