Description

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 ionisers 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.

One of the most POWERFUL purifiers in its class

Packing a powerful clean air delivery rate (CADR) of 315m³/hr, the Sqair generates more clean air than most of the competition. The Sqair is suitable for spaces up to 40 m² (430 sqft), the size of a one bedroom apartment

One of the QUIETEST purifiers in the market

On high, it sounds like soft rainfall. It is up to 12 decibels quieter than the hugely popular Dyson 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 pound than most of the purifiers in the UK

Like all HEPAs, captures virtually 100% of viruses, bacteria, PM2.5 and other dangerous pollutants

Watch the pollution collect in your filter (instead of your lungs) and enjoy the experience of breathing clean air

Why do we recommend a HEPA E12 grade filter for the Sqair?

We ran tests for different grades of HEPA filters when designing the Sqair, and we found that the HEPA E12 filter actually produced the best clean air result for the Sqair. If you'd really prefer a higher grade filter, we offer the Sqair with H13 HEPA but we highly recommend the Sqair with a HEPA E12 filter across its full use of applications

* All Smart Air filters are certified to GB13554-2008 (now updated to GB13554-2020) & GBT6165-2008 standards. This is the Chinese equivalent of EN1822 / ISO29463 and is independently tested.

Smart Air Sqair air purifier specifications

† The standard Sqair filter is a HEPA E12 (99.5%). We selected this grade HEPA as it outperformed the higher grades. We offer optional variations of HEPA H13 (99.97%) filter and/or carbon filter in our Chemical Warfare version but note the airflow and CADR will be different:

H13 filter: Top CADR 225m³/h, Airflow 520m³/h
Carbon filter: Top CADR 190m³/h, Airflow 480m³/h (note if you choose not to replace the carbon filter as you no longer have a need for it, the spec will be as shown in the main table for the HEPA version)

Frequently Asked Questions

What’s the difference between the E11, E12 and H13 filters?

Filters are graded on their ability to trap particle PM0.3 as this is the smallest particle size that travels in a straight line, not the smallest size that can be trapped. In fact, smaller particles travel in a zig zag way (called the Brownian motion) making it next to impossible to pass through the HEPA fibres. This means that most filters will trap virtually 100% of smaller / nano-particles (including the virus). If a company is saying their purifiers can trap particles smaller than PM0.3 they either haven’t done their research or, worse still, they are using this as marketing tactics to push sales. In terms of the different options for the Sqair, the different grades will capture the following percentages of PM0.3: HEPA E11 – 95% HEPA E12 – 99.5% HEPA H13 – 99.97%

Why does the Sqair not have a pre-filter?

Pre-filters add an extra layer of resistance to your air purifier by reducing airflow and increasing noise. For all our other air purifiers, the cost of efficiency was small while the gain was an increase in filter lifespan. We ran multiple tests with the Sqair and found that the costs far outweighed the gain so we decided not to include a pre-filter.

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 (9 months in the UK). 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.

What is the difference between the Sqair and Sqair Chemical Warfare?

Smart Air’s Both models of the Sqair include a HEPA filter, which is extremely effective at removing particles (allergens, viruses, dust, PM2.5, etc) from our air. The Chemical Warefare version also includes an activated carbon filter (in addition to the HEPA filter) which helps reduce odors and dangerous VOCs gas in the air. Smart Air’s range of carbon filters absorb VOC’s (Volatile Organic Compounds) such as formaldehyde, paint thinners, petroleum fuels, or dry cleaning agents. Carbon filters also remove odors.
