Best Air Purifiers To Buy For Dust-Free, Clean Air At Home — And Tips For Choosing The Right One For Your Space

Who doesn't want to breathe in clean air at home? And with the National Environment Agency predicting  severe hazy conditions in Singapore soon, ensuring that you have clean air at home should be a priority. Consider looking into getting an air purifier for the home.

What to look out for in an air purifier

As the name suggests, air purifiers clean the air but a legit one should at least be fitted with a HEPA filter. Before you click out due to the technical jargon, HEPA just refers to high-efficiency particulate absorbing and it is the gold standard in assessing the efficacy of air filters down to the size of airborne particles it can screen out in microns.  

Another consideration is the size of the space you’re looking to manage. If you rent a room or are just looking to create a better sleeping environment in the bedroom, a smaller, less powerful, less expensive model is sufficient. On the other hand, if you’re looking to purify the air of your entire house, a larger, standalone machine is the way forward.  

There are also other functionalities that air purifiers are built with these days. There are traditional single-purpose air purifiers that do just one thing and there are also those that are built with fans, dehumidifiers, mosquito catchers and some that even double as furniture.    

With these points in mind, here are the best air purifiers to buy in Singapore.
