Which Purifier Should I Buy?
Choosing the right air purifier can be difficult for first-time buyers. Here are some important things to consider:
Do you have any particular needs? E12 filters are enough for allergies and asthma, but recent renovation may require a carbon filter.
The Sqair purifier is ideal for bedrooms, but larger spaces like offices or hospitals may require the more powerful Blasts.
The main cost of air purifiers is filter replacements. Different purifiers have different lifespans and costs.

The Sqair Chemical Warfare FAQs
Are Smart Air purifiers better than other air purifiers?
Smart Air purifiers use the same cleaning principle as most other air purifiers. The technology behind air purifiers is not complex, and readily available.
However, Smart Air is the only air purifier company committed to transparent communication through open data. We avoid overcomplicating our air purifiers with high markups and marketing gimmicks. Smart Air purifiers are honest, data-backed, and streamlined to do one thing: clean air.
What room size is suitable for the Sqair?
The Sqair is recommended for rooms 36 m² (387 ft²) in area or smaller.
For larger areas, consider multiple Sqairs or one of Smart Air’s professional air purifiers (the Blast or Blast Mini), which have a higher Clean Air Delivery Rate (CADR).
Why does the Sqair not have a pre-filter?
After conducting tests, we found that adding a pre-filter will reduce the CADR. Additionally, if the pre-filter is not replaced in time, it will cause the purifier to be louder and its effectiveness to lower. Since the pre-filter will add trouble to the user, we decided not to add a pre-filter in the Sqair.
What is the difference between the Sqair and Sqair Chemical Warfare?
Smart Air’s both models of the Sqair include a EPA filter, which is extremely effective at removing particles (allergens, viruses, dust, PM2.5, etc) from our air. The Chemical Warfare version also includes an activated carbon filter (in addition to the EPA filter) which helps reduce odors and dangerous VOCs gas in the air.
Smart Air’s range of carbon filters absorb VOCs (Volatile Organic Compounds) such as formaldehyde, paint thinners, petroleum fuels, or dry cleaning agents. Carbon filters also remove odors.
Learn which filters you need in our in-depth guide on air purifier filters.
How Long Can a Sqair Last?
The Sqair is incredibly simple. This simple design means it’s built to last. When designing The Sqair, we stress-tested multiple Sqair’s by running them continuously for 10,000 hours on ‘high’. We’re confident The Sqair can last at least 10,000 hours, and normally even longer.
How to know when it is time to replace the Sqair’s Air filter?
We recommend replacing the EPA filter every 4 months. But the truth is the exact time depends on many factors such as the amount of hours used and local pollution levels. The most accurate way to determine when to replace an EPA filter is to use an air quality monitor.

Very good value on the unit; I have recommended it to friends. Higher than expected shipping costs and import taxes erased a good portion of that in my case, but if you are, e.g., in the US where the shipping is straightforward and cheap, then this is a no-brainer.

I have many air purifiers at home – this one by far is the most quiet. It has a big fan and wide surface area. The construction is fairly solid. Would recommend.

I am very happy with this air filter. I purchased two Sqairs, one for my home-based Pilates studio and one for a bedroom. Very easy to assemble and operate, love the size and style, and I love the mission of the company.
Roman (verified owner) –
So effective. Have cleared the air after burning some food when cooking and monitored the air quality improvements with my Purple Air monitor (significant improvements with SQAIR). Quickly cleans the air on the highest setting and the fan sound is not too disruptive (though certainly audible on the top setting).

Just got the air purifier a few days ago and so far it seems to be working well and it looks and feels like a well-manufactured product. One thing that slightly bothers me is the plug doesn’t seem to follow and modern polarization, it seems like something you would find on a very old appliance. I also expected the carbon filter to be bigger, otherwise, I think it has been a great purifier so far and has been working well!

Great product very happy. Good quality and the design is lovely. Plug isnt a UK plug (it’s usa) but no problem as the filter uses a ‘figure 8’ lead so easy to get a UK figure 8 lead.
I use a laser egg sensor to check the air pollution and then automatically turn the air filter on when air pollution is high (it’s in the kitchen so fluctuates when cooking). A free IFTT account makes this very simple to setup.
Only downside – had to pay import duty to import into the UK. Annoying but still cheaper than rival devices. UK import duty was approx £30.

Very happy with our SQAIR. Bought online and arrived in days to HK. On lowest setting which is enough for house if leave on during the day, is almost silent. Great airflow due to the simply and elegant design. Charcoal and HEPA filters easily accessible for changing. Apart from filtering virus particles with the HEPA filter it has also noticeably helped my daughter’s allergy to dustmites for which we did have to run the (loud) dehumidifier in her room every night. Now we just leave the SQAIR running overnight and she has no coughing since.
One super happy customer.

Overall, I’m very pleased with this air purifier (my Chinese wife bought two units for our home in China) and want to thank the ‘Smart Air’ team for all the very useful and important work they do and help they provide regarding improving the quality of the air we breathe. 😀
Don –
I have a low tolerance for noise, but I don’t notice the sound of the lowest setting at all! Number two is also fine for me. I live in a very polluted area and the Squair cleans the air well. Thanks

Got the SQAIR last week. It’s a great product to have. With this we are at peace knowing that we are breathing clean air indoors. It is worth every paisa (penny).
