6 Best Air Purifier options to Clear the Air in every Singaporean Home (2021)

Even before those reports (in May 2021) about the COVID-19 virus being airborne, air purifiers had already been seeing a steady uptick in sales. Add to this earlier studies showing that indoor air can be two to five times more polluted than outdoor air, and it’s no surprise that air purifiers have become household staples in Singapore.

One company even saw a 76% increase in air purifier sales from 2019 to 2020. It’s because “we spend a large proportion of our time indoors every day, more so during these challenging times as a result of the pandemic,” reckons Nicholas Lee, VP and Market Leader, Asia Pacific, Philips Domestic Appliances.

If you are planning to join in the quest for clean air at home, take note of what to look for when choosing your device.

Choosing an air purifier: the HEPA factor

It is “extremely important” to select an air purifier that features filtration technology and a High-Efficiency Particulate Air (HEPA) filter, Mr Lee advises.

“This filtration technology is used in many environments such as operating theatres, bio-safety labs, and healthcare facilities where clean air is crucial. It is effective in capturing and removing pollutants, bacteria, and viruses,” he adds.

But doctors say that there is no proof that these can fully protect you from the virus.

“HEPA Filters can filter airborne viruses. However, their efficacy depends on the viral load in the air, and the size of the viral particles,” says Dr Benjamin Loh from the DTAP Clinic.

“The HEPA standard was not designed to handle airborne viruses specifically, so expecting complete protection from airborne viruses may be overly ambitious,” he adds.

But air purifiers are still useful

Still, air purifiers can be beneficial, especially in enclosed spaces where there is poor ventilation. And of course, masks, and personal hygiene remain crucial in helping to prevent infection. Furthermore, there may be other reasons why you may want to have an air purifier at home.

The risk of lower respiratory tract infections increases when there is exposure to particle pollutants. It is believed that pollution damages the airways, increasing the risk of infection. It may also have adverse effects on the immune system, affecting its ability to fight off respiratory infections. Hence it is still an excellent decision to use an air purifier as there are huge health benefits to breathing cleaner air, Dr Loh assures.

This is especially so if your child (or anyone in the household) has a pre-existing condition like asthma, allergic rhinitis, chronic lung diseases, or eczema. All these can be exacerbated by pollution.

Statistics also show that outdoor air pollution is associated with low birth weight, and can adversely affect foetal growth, says Dr Loh.

“Everyone can benefit from less exposure to air pollutants. Babies, young children who tend to have more allergies, the chronically-ill with weak immune systems, and the elderly stand to benefit the most from air purifiers,” he confirms.
