You’ve probably heard of air purifiers being talked about in offices, homes, and other establishments, and how people claim it to be effective. So you Google “are air purifiers a waste of money” to satisfy you with an answer. Well, you’ve come to the right article!

Air purifiers can vary in price, but do they really work? The short answer is yes, they do work. The long answer, well, we’ll explain it in this short article.

As we mentioned above, yes, air purifiers actually work. The way they do this is through a series of layered technologies such as filters and sometimes even UV light. These filters are usually in the form of true HEPA (high-efficiency particulate air) filters, which are common in most air purifiers.

The job of this filter is to clean up the air in your home. An air purifier uses this filter like how you would put one of those refills in your plug-in scent in your bedroom or car. The filter gets dirty after some time and you have to either clean it up or replace it.

If you’re looking for which air purifiers work best for sneezes and wheezes, you’re in luck because we previously wrote a review of some of the best air filters for asthma and allergies.
