The right air purifier can help safeguard your health. Here are our 8 picks and tips on how to pick a good air purifier.
So you’ve been religiously washing your hands and using hand sanitiser, masking up as much as possible, and trying to steer clear of crowds, strangers and crowds of strangers. Is there anything more you can do to keep you and the people around you safe and healthy in these trying COVID-19 times?
Why, yes there is. Considering that we spend hours of our day in our bedrooms, homes and offices — and sometimes sharing the space with others — it might be a good idea to pay attention to the air quality at these locations.
Health benefits of air purifiers
Using an air purifier is a convenient and effective way to ensure clean, fresh air in your bedroom, homes or office.
Thanks to advances in technology, consumer grade air purifiers are capable of filtering the air we breathe to remove fine micron-sized particles, such as dust mites, pet dander, pollen, dust, smoke, gases, fungi, bacteria and viruses.
Air purifiers clean the air by using multiple layers of filtration — with HEPA (high-efficiency particulate air) filters as the gold standard. Some models also include additional features such as air humidification, UV light steriliser, ion technology or biochemicals to destroy harmful microbes.
Using an air purifier with HEPA (or equivalent) filter results in sanitised, fresh-smelling air free of irritants, toxins, or odours, and may also safeguard against airborne viruses such as COVID-19.
It can also lessen or prevent allergy flare-up among sufferers by reducing or eliminating allergens in the environment. At the same time, the constant filtering and removing of dust and fine particles reduce dust build-up and helps keep your space clean.

Things to note before you buy an air purifier
When in doubt, go with the big brands
While air purifiers come in many brands and makes, it is worthwhile to go with trusted big name brands, even if you have to spend slightly more. The last thing you want is to spend money on an untested brand, only to receive a substandard product that is noisy, runs hot, of poor quality or doesn’t work as advertised.
Consider filter lifespans
All air purifiers will need to have their filters replaced with use — typically after 24 to 36 months of usage — in order to continue functioning well. You should take the cost of replacement filters into account when choosing an air purifier, as some brands may be more expensive than others, while others may last longer. Also, choose the right type of filter according to your needs; there’s no point paying extra for premium filters if you or your family have been doing ok with a regular one installed.
Buy only genuine replacement parts
Resist the temptation to buy counterfeit filters or replacement parts, even though they may be cheaper and claim to have the same capabilities. Using fake filters generic replacements may affect the effectiveness of your air purifier. In the long run, they may also cause damage or other problems which could shorten the lifespan of your air purifier.
Choose according to room size
Be sure to pick an air purifier with an effective coverage that is close to the size of the room you plan to use it in. A purifier that is too small won’t be able to properly do the job, while picking one that is too large won’t make your room ultra clean, well not beyond the capacity of the device anyway. You may want to consider getting a mix of large and small air purifiers for the best fit.
Be sure to shop around
For simplicity, we have linked the best deal we found for each of our 8 picks at the time of writing. However, you should know that air purifiers are sold by a great number of vendors that include big box electronics stores to independent agents online. If you’re interested in a model, be sure to spend some time shopping around. You just may score a sale, or be offered a newer model for the same price range.
Don’t forget your credit card perks
As air purifiers fall under electronics, you can get more bang from your buck if you charge them to the right credit cards. For example, the OCBC Titanium Rewards Credit Card – Blue Card FaceOCBC Titanium Rewards card offers 10x points (equivalent to 4 miles per dollar) when you spend at electronics stores. Another great credit card is the American Express CapitaCard, which gives you bonus points when you shop at CapitaLand Malls.
