Have you ever wondered why air purifiers are becoming so popular these days? A quick search will show you hundreds of articles that swear by this contraption.

But, do they really work?

Air purifiers, also known as air cleaners, are one of the most marketed household products in the market today. They claim to “cleanse” the air around you, providing you with clean and pollutant free air to breathe.

Most of the times, advertisements over hype a products’ uses and when you buy them, you end up getting disappointed. This is not true in the case of air purifiers – they actually do what they are advertised to do (more on that in a while)!

But first, you need to understand what an air purifier is. An air purifier is an electronic device that can remove the contaminants, such as dust, pollen, smoke from cigarettes, pet dander, etc., from the air in an enclosed space. Thus, this device is ideal for people prone to illnesses like asthma or breathing problems, people with allergies and infants.

Today, there are hundreds of air purifiers in the market and the number of companies manufacturing them has steadily risen in the past decade or so. But, you need to understand that only a specific kind of air purifier is helpful – the others are just a sham or just work in limited conditions that cannot be always met.

The air purifiers known as the HEPA purifiers (high energy particle air purifiers) are the best in the market and actually remove the major contaminants from the air. These are some of the most expensive air purifiers available but are worth every penny you spend.

These HEPA purifiers are proven to remove contaminants that are larger than 0.3 microns from the air, with an almost perfect success rate of 99.9 percent. Air contaminants that are usually larger than 0.3 microns are asbestos, pollen, dust, pert dander and cigarette smoke. So, for people with allergies or breathing disorders or for infants, the aforementioned contaminants can be extremely dangerous, resulting in reactions, diseases, or in certain cases, may even be fatal!

Air purifiers are a boon for such a household, even if they can cost a lot, need to be installed by a professional (in some cases) and use up a lot of electricity – the cost really is worth your health! Check out this best air purifier.
