There might not be earthquakes or volcanic eruptions in Singapore, but thanks to the annual haze from our neighbours down South, we have our very own environmental disaster.
Unless you’re planning to get an N95 mask implanted in your face or are happy breathing in the sweet, sweet smog each year, it could be a good idea to purchase an air purifier.
How to choose an air purifier in Singapore
Not all air purifiers are going to be that useful in the haze. The best filters for getting rid of that pesky particulate matter are HEPA filters. Here’s a run-down of what the various filters do.
- HEPA filters – These can filter particulate matter that are as small as 0.3 microns. These are the filters that get rid of the dangerous tiny particles that can make their way into your bloodstream.
- Ultraviolet (UV) filters – These filters are meant to get rid of bacteria, viruses, moulds and other biological contaminants.
- Photo-catalytic filters – These filters get rid of dangerous gases, and are mostly used to get rid of bacteria, viruses and the like.
- Activated carbon filters – These get rid of odours, so they’re perfect if there is someone in your home with very smelly farts….
While nobody can tell you definitively which air purifier is the best for you, here are some factors to bear in mind.
- Air flow – The air purifier can only clean the air that flows through it, so higher air flow levels mean the machine is more efficient.
- Air changes – A higher number of air changes per hour means the machine is cleaning your air more efficiently. Asthma suffers are advised to get purifiers that make at least 4-8 changes an hour.
- Noise levels – Air purifiers that contain fans tend to have higher air flow and better cleaning capabilities, but also make more noise.
- Area coverage – If you’ve got big rooms, you’ll need greater area coverage. Check the CADR number to see how wide an area the air purifer can cover
