Sterra Air Purifier

Description of Sterra Air Purifier

The Sterra Breeze Air Purifier is a device that claims to clean and purify the air in your home. This product is made in Singapore and the manufacturers claim it can remove harmful airborne particles like viruses, smoke, and allergens.

Cleaning this air purifier is easy, Just pull out the air filter and vacuum it or wipe it with a dry cloth. Also, remember to put the filter under sunlight regularly to sterilize it.

I was looking for a new air purifier for my home. I do have a small air purifier that I previously owned, but it was not working well and I was casually browsing through Tiktok, I stumbled upon this intriguing air purifier – Sterra Air Purifier. With numerous options available, I decided to do some research and take a chance on it and ordered for 2.

When my Sterra purifiers arrived. They were slightly smaller than I anticipated, but they arrived well-packaged and in good condition. I must give credit to Sterra for their excellent packaging.

Regarding the purifiers themselves, they operate quietly, which is a pleasant surprise. I’ve had them running for about 3 days now, and according to the instructions, it may take up to 2 weeks to notice any results. Therefore, I’m patiently waiting to see if they deliver on their promises. Since it’s only been a few days, I’m reserving judgment on their claimed benefits for now.


  • Operates silently
  • Has child lock features
  • Ideal for individuals with allergies


  • It’s too pricey
  • There are lots of customer complaints
  • Requires regular maintenance

Does The Sterra Air Purifier Work?

It works but there is no strong evidence to prove they make you healthier or help with allergies and breathing problems. But if you have allergies or asthma, using one with a HEPA filter could be helpful because it’s good at removing tiny particles from the air.

Why People Feel It’s A Scam

The truth is Sterra keep getting local tiktokers to promote their products, There are lots of customers reports on Reddit and top review websites that confirm this. Also the customer reviews are suspiciously all 4 and 5 star only on their official website.

Also Sterra website keeps advertising their product to be on sale ($229 from original price of $479), don’t fall for that trap. We checked out a popular website Futur Living and discovered that they sell the exact same thing for $199 which includes the UV feature without the additional $50 cost. Alibaba and some other China sites sells them for $50, ridiculously overcharged.

Refund policy is crazy and unfair.

  • “Refunds and cancellations are strictly before delivery and within 3 days of purchase.”
  • “Refunds and cancellations are strictly before delivery. After 3 days of purchase, will be subjected to a cancellation fee of $200”

I feel that more people should be aware, and shouldn’t fall into the traps of all this marketing on Facebook and “influencer” crap.

Customer Reviews And Feedback

Yet another “support local” rebranded overseas manufactured schtick just like PRISM+. Overpriced af, and if it isn’t from the base unit itself, it’s from the filters. I have 4x of the Breeze purifier, and the filters only last for 60 days! WTF. The purifier change indicator is programmed to countdown the days instead of actually measuring the filter, as you can easily reset it by holding the button down. So who is to say if the filters really do last only for 60 days, or the units are programmed to indicate a change based on a preset value like 60 days… Definitely one of the worst purchases made in my household the last few years, and it’s even more infuriating as it was bought by my parents on an impulse without my advice.

And guess what? These companies also do deceptive marketing. “ON SALE” but been on sale at that price for years. Pretty baffling that singapore got no consumer protection against this kind of business strategy

Comparison with other air purifiers in terms of pros and cons

When you compare Dyson, Sterra, Cosmo, and Xiaomi air purifiers, each brand has its own special features and performance.

Dyson air purifiers are known for their stylish look and effective cleaning with filters and fans. Sterra, a local brand, focuses on purification, removing nearly all airborne particles. Cosmo puts a lot of effort into thorough air cleaning. Dyson is the quietest, then Sterra, and then Cosmo. They’re all quieter than the noise of the street.

All four brands use special filters to catch tiny particles, with Cosmo having extra layers to handle odors and kill germs.

When picking an Air Purifier, think about:

  1. Room Size and Air Needs: Make sure it can clean the air in your room. If you have allergies or asthma, you might need a stronger one.
  2. Noise and Energy: Check how loud it is, especially if you’re using it in a quiet room. Also, see if it’s energy-efficient to save money on electricity.
  3. Price and Warranty: Look at the cost and what warranty options are available. It’s important to find one that fits your budget and offers good protection.


Finally, the Sterra air purifier offers effective air purification with its smart features and germ-killing capabilities. However, you should know that Sterra frequently teams up with local TikTok personalities to promote their products. This is something many customers have noticed and talked about on platforms like Reddit and other review sites.
