Best Air Purifier in Singapore

Best Air Purifier in Singapore (2021 Ranked & Reviewed)

In Home tech by Kenny LeeLeave a Comment

Wait, aren’t all air purifiers just ventilator fans fitted with fancy enclosures?

Apparently not. That’s what I’ve concluded after going through dozens of reviews and using one for a couple of years.

If you’ve had enough of the perennial haze problems or trying to cope with indoor allergies, getting an air purifier helps.

The question is, which air purifier is best for budget-conscious Singaporeans.

Read on, and you’ll have all the answers you seek.

Hottest pick

An improvement from its predecessor with true HEPA class 13 filter that captures tiny airborne particles. Great price, sleek design and clean air.

It seems that Xiaomi is having success not only on smartphones but also in its venture into house appliances.

The Xiaomi Mi Home Smart 3H boasts an attractive design that fits easily into modern homes. It’s upgraded OLED panel, and the convenience of app control makes it attractive for tech-savvy users.

Xiaomi made some bold claims on its performance, which includes:

  • Effectively filters particles as small as 0.3 microns
  • Delivers 6330 litres of purified air per minute
  • Compact, quiet, non-intrusive

You’ll want to compliment Xiaomi for keeping the winning features of its predecessor, which boasts a slimmer design, yet powerful airflow. Its airflow coverage is only rivalled by the top-of-the-class Xiaomi Air Purifier Pro

There are grouses of the old 2S model, which uses an inefficient EPA filter. The introduction of the true HEPA filter in this iteration is a significant change that makes it the best air purifier in every area.

Also hot

It's a quiet yet efficient air purifier that removes airborne particles with the proprietary Plasmacluster technology. It’s both economical and reliable. 

It turns out that I’m not the only one loving the Sharp FP-J30E Plasmacluster air purifier. A quick check at online retailers also showed that it’s one of the best-sellers. 

I have to admit that I was attracted to its budget-friendly price, but I later found that it is a good catch in terms of a functional air purifier. It can be operated in a few modes, which alter the fan speed and the Plasmacuster effect. 

I’m a light sleeper, and I’m thankful that Sharp’s air purifier is quiet enough in its regular cleansing mode. You wouldn’t realize that it’s powered on until you’re just a step away from it. Nothing fancy on the controls as the buttons are pretty much self-explanatory. 

What’s decisive in choosing this air purifier is that it’s fitted with a HEPA filter, which is essential to trap microparticles safely within it.

Why you can trust our advice

I spent the past 4-years dealing with dust mite allergies. That was how I started exploring air purifiers, dehumidifiers and robot vacuums to reduce the allergies.

I was also an electronics engineer, which means I go beyond marketing jargons when I’m researching for the best air purifier in Singapore. I look into terms like CADR and how it affects the performance of the air purifier.

Of course, I was looking for an air purifier that isn’t too expensive. That’s how I ended up with a Sharp air purifier. After 4 years, it’s still working beautifully in my room. 

And guess what? I’m no longer sneezing as frequently as I used to.

Why We Picked Out Xiaomi Mi Home Smart 3H And Sharp PlasmaCluster FP-J30E

I’m not one who goes nuts over Xiaomi’s products, but I have to admit that the Xiaomi Mi Home Smart 3H is quite flawless. 

You can’t argue that it’s space-saving and minimalist design fits into almost any modern homes. It’s also smart-home ready, as you can connect it to Mi Home app along with other smart appliances from the company.

What really convinces me is that the Xiaomi Mi Home Smart 3H is not just a pretty-looking air purifier. With the introduction of the true HEPA filter, it has proved to be effective in removing microparticles from the air and in a relatively short period.

Besides, it’s low price tag makes it all the more worthwhile.

I remain steadfast in choosing the Sharp FP-J30E Plasmacluster as the runner up. While it lacks many advanced features, the simplicity of the unit is perfect for a minimalist like me.

Coming from an established regional brand, it’s reliable and does seem to help in reducing allergies. I could keep it running for days without any issues.

How To Choose An Air Purifier

Promotions and rave reviews are not solid reasons to buy an air purifier. Instead, you ought to consider the following factors when choosing an air purifier.

  • Coverage - Some air purifiers are built for smaller rooms, and it will not be effective if you place them at living rooms. 
  • CADR rating - It stands for Clean Air Delivery Rate, which is a standard for measuring the air purifier’s efficiency in cleaning the air. CADR is rated in m3 /hour, and a larger value means a more powerful air purifier. 
  • Noise-level - Fan-based air purifier produces a certain amount of noise (although not as loud as air conditioners), which is inevitable. What’s important is that the noise is tolerable at its highest speed and barely noticeable when operating at night mode. 
  • HEPA-filtration - An air purifier needs to be equipped with a HEPA filter or equivalent if you’re using it to remove microparticles from the air. For a filter to meet the HEPA standard, it has to trap 99.97% of 0.3micron particles from the air that passes through.
  • Energy-efficient - Usually, you’ll run the air purifier for long hours, and that means you’ll need to get one that consumes minimum power. 
  • Replacement filter - The air purifier is as good as the condition of its filter. Usually, the filter will last between 6 months to 1 year, depending on the environment. Ensure that replacement filters are easily available, or you’ll end up with a dysfunctional air purifier.

What does an air purifier do?

An air purifier cleans the air by trapping allergens, pollutants, VOCs, and dust mites with the filter. It uses a fan or vacuum to circulate the air in the room, where dirty air is gradually replaced with filtered, clean air. 

Where to buy Honeywell air purifier in Singapore?

Honeywell may not be a household name in Singapore, but it does have a range of decent air purifiers.

You can check out some of the options here at Lazada or Shopee. The Honeywell HPA710 is particularly effective in removing allergens from the air.

Can I wash the air purifier filter?

Unless the filter is labelled explicitly as washable, you shouldn’t attempt to wash it with water or cleaning agents.

It is strictly NOT recommended to wash HEPA filters, even if you’ve read otherwise. Washing HEPA filters are known to decrease its efficiency significantly.

Does an air purifier remove odours?

An air purifier is capable of removing odours only when it’s fitted with an Activated Carbon Filter or equivalent.
