The Sqair

Treat your body right, experience the cleanest air in the world.



What Makes The Sqair Special?

As a B-corp social enterprise helping the world breathe clean air, we designed the Sqair because we were tired of the gimmicks and BS from current air purifier companies. The Sqair gives you far more clean air at a fraction of the cost of the purifiers from those “big guys”.

How did we do this? We cut out the fancy marketing gimmicks such as ionizers and photocatalytic filters that science shows can actually make your air worse. We designed the Sqair for performance, not marketing ploys. The Sqair is data-backed and is excellent at one thing: cleaning air. And it does that better than its competition.

The Most Powerful Purifier In Its Class

Packing a powerful clean air delivery rate (CADR) of 315m³/hr, the Sqair generates more clean air than its competition. The Sqair is suitable for spaces up to 40 m² (430 sqft), the space of two large bedrooms.

Cleans a 40m2 room in just 25 minutes.

One of the Quietest Purifiers on the Market

On high, it sounds like soft rainfall. This is up to 13 decibels quieter than the hugely popular Xiaomi purifier, yet provides more clean air and costs less.

Blows the Competition Out of the Water on Both Price and Effectiveness

The Sqair gives you the most clean air per dollar of any purifier in the world. And it’s not really close.

More Clean Air, at a Fraction of the Price.

Captures over 99.5% of Viruses, Bacteria, PM2.5 and Other Dangerous Pollutants

Watch the pollution collect in your filter (instead of your lungs) and enjoy experiencing the cleanest air in the world.

Which Purifier Should I Buy?

Choosing the right air purifier can be difficult for first-time buyers. Here’re some important things to consider:

1. Know Your Purpose

Do you have any particular needs? HEPAs are enough for allergies and asthma, but recent renovation may require a carbon filter.

2. Know Your Size

The Sqair purifier is ideal for bedrooms, but larger spaces like offices or hospitals may require the more powerful Blasts.

3. Know the Costs

The main costs of air purifiers are filter replacements. Different purifiers have different HEPA lifespans and costs.

The Sqair 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 40 square meters (430 sq ft) in area or smaller. Even in a 40 square meter room, the Sqair is able to clean all the air in the room over 3 times in just 1 hour on high.

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 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?
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 HEPA filter?

We recommend replacing the HEPA filter every 6 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 a HEPA filter is to use an air quality monitor. Learn More: How to use an air quality monitor to test a HEPA filter

    Investment for our health. My friends had one of these in China, but I was given a bigger, more expensive air filter. Sqair works better, is quieter, takes up less space, and looks better. When I came back to Australia I ordered a Sqair for my new place. It helps when there are fires around, from fireplaces in winter to next door neighbour’s huge bbqs. It helps the persistent cough that I usually have during winter. And, now they say it will reduce the risk of Covid which will be great when I have visitors again.

    Arrived quickly, works and looks great in my home. I like that it’s quiet and really easy to assemble and use. I found the information on the website helpful. I bought it because of the wildfire smoke in Canada and I’m sure it will help us breathe better.

    Bought one Sqair for our bedroom…..Ordered another one for the livingroom whilst getting more filters…Looks good and cleans the air, love it!
    Only downer was it was a little dirty out of the box but nothing that wouldn´t come off with a cloth and water.

    Overall it works very well. It looks good, is easy to assembly, easy to use (only 4 settings including “off”), and is easy to take apart. I usually run it on level 2/3 and it has replaced my noise machine in my room (which I had used when sleeping before getting the Sqair.

    The Sqair works. One of the best investments I’ve made. Easily pays for itself many times over in terms of tangible benefit to my health and reduced sick days and medicine. Will get one for my office as well, probably.

    I’ve got cat allergies. My daughter has cats. As you can imagine, this poses a challenge. The SQAir has made a noticeable difference. I’m still stuffy all the time, but over the past two weeks, things have gotten noticeably better. The air in my pandemic office also “tastes” better from the rest of the house. Since my filter was being borrowed by family members, we bought one more. It now lingers over the outofsight kitty litter box, noticeably reducing emissions. Yet, borrowing still happened — so we ordered even one more. Once the “mini-blast” is available in 120v, we will probably order it for the main floor of our apartment, and gift the 3rd SQAir to a nearby sibling.

    What I like the most about this filter is that it is… simple. No shiny LEDs or complex dials or beeping panels. It has 3 fan speeds. I use “1” when I am in the room (working or sleeping), and “3” when I am absent. The lowest setting is relatively quiet, at least with the ambient noise of the city: sitting next to it, I hear a faint electric hum; across the room, it is barely audible. The highest setting circulates air in the room better, on this setting the white noise of the air being expelled drowns out the motor humm. We have it on “2” over the cat litter box, this seems like a nice compromise between noise vs air flow. Having 3 levels, and no more, is excellent user interface design.

    The build is attractive and solid. It seems kinda “Apple” feel: white with clean external design. It is light enough to be moved around the house. The 4 wood feet (needed for space for fan intake) are removed for shipping, but putting them on is trivial. I understand that every 3 months we will need replacement HEPA filters. I’m looking forward to the US distributor so that this does not become prohibitively expensive.

    Its amazing the amount of data these people have put out on their blogs and on their website. If you understand that an air purifier does not need to be complicated and is an extremely simple device, you will see no reason to spend any more money on any other brand. All Their data is verified by 3rd party labs btw, no joke. The other companies might be good also, but this is hands down the most bang for buck, Sexiest looking air purifier. Build quality is great for the money and this thing is built to last. I don’t want bells and whistles, fancy leds, just an air purifier that works. This one does the job and does it quieter than the competition.

    I’ve been using this filter in Ho Chi Minh City, Vietnam, and it works great (I purchased a laser egg air monitor with it, and found that the sqair cleans the air in our bedroom within a few minutes on the medium setting). The design with the filter on the bottom of the unit and the air coming out the top is really thoughtful– The top of the unit stays clean and dust-free, and the filter media stays safely out of reach of curious hands and fingers. It’s effective, no-nonsense, and gimmick-free. The filters last a long time and are much cheaper than competitors, even with shipping. The only thing missing that I would like to see is pre-filters for the sqair.
    Planning to purchase another sqair for another room. I highly recommend!

    Have had The Sqair since it’s launch. It’s the best air purifier I have come across in the last 15 years (and I had them all!). Quiet, effective, and a great design. Well done!

    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 Sqair cleans the air well. Thanks

    I have Sqair since November, it has been a very pleasing experience. The USP of this product is its simplicity and efficiency. I recommend to everyone.

    Buy this, breathe deep, and never look back. A no nonsense quality product that is super effective, quiet and stylish (because we do all actually need to show off to the neighbours). I’ve been buying from SmartAir since they launched. This is the best product to date and the affordability of the unit and new filters is unquestionably the best offer on the market.

    Been using the Sqair for a couple of months now and I am extremely satisfied – it’s an excellent air purifier for smaller spaces (it works great in my bedroom!) and the price is lower than any other comparable product from bigger brands. Sleek, stylish and compact – so it goes well with your interior decor in any household.

    We are happy to get such a Stylish, Compact & Noise free product for our office.

    Have been using the sqair for the last week. its beautifully designed, works silently in the background even on the highest fan speed and brings down particulate counts in my bedroom very quickly.

    Super happy with The Sqair! It’s an excellent air purifier and is very reasonably priced, unlike most other air purifiers that are either not up to the mark or are very heavily priced.
