Uncompromising air quality, without the noise.

The Smart Air Sqair is a masterclass in purposeful design — a purifier stripped of gimmicks and engineered entirely around one goal: delivering the cleanest air possible. No ionisers, no photocatalytic filters, no questionable extras. Just genuine HEPA E12 filtration moving up to 315 m³/h of clean air through your home, quietly and efficiently.

With a CADR that outperforms purifiers at twice the price, the Sqair is suited to rooms up to 40 m² — from open-plan living spaces to generous bedrooms. Its understated, cubic form sits comfortably in any interior without demanding attention, while its mechanical three-speed dial keeps operation refreshingly simple.

Available with an optional activated carbon upgrade for odour and VOC control, or with an H13 HEPA filter for even finer particle capture.

Why the Sqair

True HEPA E12 Filtration
Captures 99.5% of airborne particles at PM0.3 — including fine dust, pollen, pet dander and mould spores — in a filter system free from performance-undermining additives.

315 m³/h CADR
One of the highest clean air delivery rates in its class. Designed to clean a 40 m² room multiple times per hour, even on a mid setting.

Optional Carbon Filtration
Add an activated carbon layer to neutralise cooking odours, VOCs, and household gases — available as a standalone or dual HEPA + Carbon configuration.

Whisper-Quiet Operation
From 23 dB on its lowest setting, the Sqair runs unobtrusively through the night, in a study, or alongside a sleeping child.

Simple by Design
Three mechanical speed settings. No app required. No complicated menus. Clean air, on your terms.

Performance without pretension. This is air, made honest.

Frequently asked questions

What size room is the Sqair suitable for?

The Sqair covers rooms from 15 to 40 m² (up to 430 sq ft), so it suits everything from bedrooms to open-plan living spaces. It delivers up to 315 m³/h of clean air, which is enough to clean a 40 m² room multiple times per hour.

How loud is it, and can I use it in a bedroom?

It runs at 23 dB on its lowest setting and up to 52 dB(A) at maximum, so the low setting is quiet enough to leave on overnight, in a study, or near a sleeping child. It has three mechanical speed settings controlled by a simple dial, with no app or menus.

What filter options are available, and how often do I need to replace the filter?

The standard filter is HEPA E12, which captures 99.5% of particles at 0.3 microns, including dust, pollen, pet dander and mould spores. You can also choose an H13 HEPA filter for finer particle capture, or add activated carbon for cooking odours and VOCs, as carbon only or dual HEPA + carbon. The HEPA filter lasts around 6 to 9 months when run 8 hours a day.

How much power does it use, and what warranty does it come with?

It draws between 6 W and 38 W depending on the speed setting, so it's inexpensive to run for long periods. It operates on 220 to 240V, has a 1.8 m detachable power cord, and comes with a 1-year warranty.
