Clean air that does the job, for less.

I really like this product. On low intensity, the fan is barely noticeable, which is great. It has definitely improved the air quality.

Needed an air purifier for the house as wife and daughter were constantly falling sick with congested nose. Did some research and ended up with the SqAir, and turned it on and could feel the difference in air quality immediately.

Wife’s and daughter’s symptoms also improved dramatically after the first night.

Effectively removes cooking smells from my caravan and have noticed my allergy reactions not so strong when entering caravan which seems to act like a pollen trap.
I blast level 3 when first turning on which is quite noisy then drop to level 1 which is quiet enough to live with. I sleep in a different space so do not have this one on at night.

Every morning my daughter would be in pain from sneezing all morning and eyes watering and red. This has overnight changed her symptoms, and after only a few days of it running in her bedroom she wakes with no more hayfever symptoms! Absolutely worth it's weight in gold!

Really been loving our SA600 Air purifier, and these HEPA Filter's are the perfect match.
You don't have to use the carbon filter if that doesn't suit your use case. We only use the HEPA Filters, and the fit is so tight against the machine, that there is no play or movement.

Love the multi stage filter design, it's all very smartly put together. On low settings for steady state operation it's super quiet, and if you need to filter things quickly you can kick it up to high. Very happy with it and I'd very much recommend it to others.

I no longer see fibres and dust floating around my lounge after folding washing, and I’ve stopped having to take antihistamines as often. Simple but really works, way better than our previous Dyson air purifier. I’m literally about to place an order for another identical one for our bedroom.

Was impressed with the build quality of this unit, solid metal which is rare these days. Makes it fairly heavy, but easy to wheel around. Can feel it pushing a lot of air around on high, and it's quieter than other air purifiers we've had before. Perfect for our office!

Simple and elegant. Does what is advertised with no fuss.

This air purifier was actually a lot bigger than I thought it was going to be. It looks great and the 3 different fan speed options should work for everyone.
Great device.

The lowest setting is so quiet, I forget it's on.

It is nice to open an air purifier and have so much less packaging to deal with. The packaging that is included is (seemingly) sustainable by being recyclable or compostable.

The unit is sturdy, fairly well designed, and works well. It is energy efficient particularly on the lower modes, and the large true carbon filters work considerably better than the typical cylinder designs with minimal carbon.

By having two large fans for airflow, the unit is very quiet on the 1 and 2 modes while moving a considerable amount of air. On mode 3 the noise is tolerable but definitely audible. Modes 4 and 5 are much louder and use considerably more power but moves a lot of air rapidly.

The lights to indicate the modes are a bit confusing - clearly retrofitted from the prior design while increasing the modes from 3 to 5 while keeping only 3 LEDs. I also like that the lights turn off by default. It has everything you need and nothing you don't.

My critiques would be that the design is made in a way that you can't really place it near a wall because the intakes are on both the front and back, thus blocking an intake if you place the purifier out of the way. It also blows air in strange directions - predominantly directly up, and slightly to the right, but nothing to the left. This is not adjustable and doesn't seem to be a conscious design choice but rather a side effect of the top grill designed to look stylish.

The fans are located toward the bottom of the unit, but the filters cover the entire sides. This means the bottom 2/3 of the filters take up most of the dust and get covered, while the top 1/3 remains relatively clear. It may be useful for me to flip the filters at some point during their lifetime if it's possible - I think they're designed in a way that would allow that.

The shipping tracking wasn't very good and the unit showed up by surprise, but otherwise the ordering experience was smooth.

I like the environmentally friendly design. My one final critique would be repairability. The ability to easily replace the fans or other components if they do break (and being able to buy or request these parts) would be an awesome bonus in an attempt to create a more circular and sustainable economy.

Customisability would be a nice added bonus - the white colour easily shows dust collected on the unit and is very boring (which, is intentional and allows it to fit in anywhere). But, it could be cool to have custom panels available for stylish looks given how easy they are to pop on and off or different colour options available. The holes in the grill could allow you to pop on little "charms" if you really wanted to make it feel a little more custom.

Overall, I say this unit "slaps".

As described, efficient. You should buy it!

Glad we stumbled upon this product and company, it’s been a good solution to our search for healthier air for our children. Looks good, can hardly be heard on #1 setting, and we appreciate the simplicity of the product. Would buy again.

The Smart Air SA600 arrived quickly and was easy to get set up. What stood out most is how quiet it is, especially at night, it runs so quietly you hardly notice it’s on. I got this to remove allergens and pollen, the air feels noticeably cleaner and easier to breathe. Overall, a simple, effective air purifier that does exactly what you want without any fuss.
