Thinking of investing in an air purifier for your home? Here’s what you need to know about choosing the best air purifier for your needs
If you are researching how to ensure your home has clean air, an air purifier is what you’ll need. Many modern air purifiers can kill up to 99.9% of viruses, such as COVID-19 not to mention remove cigarette smoke and dust. If your family suffers from allergies (dust, pet dander, mites), then a good quality air purifier may help! And while we are grateful that the haze situation in Singapore is under control at present, when the air quality was at its lowest, having an air purifier was key to ensuring good-quality air for the family to breathe! These handy devices offer plenty of benefits, and we’ve got a quick guide below to get you started. Plus, we share a few best air purifiers in Singapore that you can invest in.
How does an air purifier work?
An air purifier is a portable device that uses an internal fan and filter to remove unwanted particles, dust and other nasties from the air in the room – remember when haze in Singapore was a thing? Air purifiers to the rescue! Once purified, the air is then circulated back into the room. This process repeats itself multiple times, boosting and keeping your indoor air quality at optimum levels. It’s important to note that no purifier can capture every single pollutant or harmful particle in your room. However, many air purifiers use HEPA filters to eradicate as many allergens and unwanted substances as possible – these include dust, pollen and even mould spores. Wondering what a HEPA filter is? An acronym for “high-efficiency particulate air (HEPA)” filter, it, in theory, removes up to 99.997% of airborne particles that contaminate the air.
Air purifier benefits
Wondering how an air purifier can benefit your family? Not only do these devices help rid your home of dust and mites, but air purifiers can also help remove unpleasant odours, allergens and lots of other harmful substances that affect your health. It keeps the air in your home cleaner, reduces dust collecting around the house, and has even been said to help reduce the effects of asthma. Air purifiers also keep pet fur from spreading everywhere, and are a great way to minimise airborne diseases, which works great if you’d like to reduce your risks of a Covid reinfection.
Dehumidifier vs an air purifier: Which is better?
An air purifier and a dehumidifier work in different ways. The dehumidifier helps remove trapped water in a room, which then lowers humidity to create a drier environment. An air purifier cleans the air, keeping it free from anything harmful that you may inhale. However, both devices are useful in battling dust mites, as the dehumidifier reduces humidity levels so dust mites can’t thrive and the air purifier removes dust, which is the food source these mites feed on.
Choosing an air purifier
The NEA recommends air purifiers with High-Efficiency Particulate Air (HEPA) filters which remove fine particles more effectively. It’s recommended to buy air purifiers with a cleaning capacity (“floor area and flow rate”) that matches the size of the room being cleaned. The NEA provides a list of air purifier models and suppliers on its website, though they do not endorse any of these air purifiers or companies.
