Blueair Blue Signature SP3i Air Purifier
:quality(90)/https://www.sleepsolutions.com.au/media//wysiwyg/Products/Blueair/SP3I/blueair-sp3i-group.jpg)
Serious air cleaning, in a footprint that actually fits
The Blue Signature SP3i is the medium model in Blueair's Signature range – and it is the one most Australian homes are looking for. It stands 49 cm tall on a footprint under 30 cm square, so it slips in beside a bedside table, a reading chair or a desk where the larger SP4i simply won't go.
Inside, it runs Blueair's 7-stage HEPASilent™ filtration, capturing 99.97%² of airborne particles down to 0.1 microns. OdorFence™ adds bio-based enzymes and minerals that break odour and gas molecules apart at a molecular level rather than just trapping them – up to 10x³ the odour removal of a standard carbon filter.
What sets the SP3i apart from the rest of the range is its smart VOC sensor. Alongside PM2.5 particle monitoring, it tracks the gases and chemical pollutants you can't see or smell, and adjusts automatically as conditions change.

A motion-activated dot matrix display wakes as you walk past, so air quality is something you glance at rather than something you go looking for. The flat top surface doubles as a side table, and the whole unit is finished in Swedish-designed Nordic Fog fabric that you can swap for another colourway whenever you feel like it.
- Cleans 46 m² in 12.5 minutes, and up to 209 m² in an hour
- Smart VOC sensor detects gases and chemical pollutants, not just particles
- 7 stages of filtration removes 99.97%² of airborne particles down to 0.1 microns
- 10x³ more odour removal with OdorFence™ Technology

- Wi-Fi connected, with scheduling and filter tracking in the Blueair app
- Doubles as a side table, with optional leg and ring bases
- 3-year warranty when you register your product

Why choose the SP3i?
The SP3i sits in the sweet spot of the Signature range. You get the same 7-stage HEPASilent™ filtration, OdorFence™ odour breakdown and smart app control as the larger SP4i, plus a VOC sensor the SP4i doesn't have – in a body that's taller and narrower, and 1.7 kg lighter to move between rooms.
At 19 dB on its lowest setting it's quieter than a whisper, which matters if it's running in a bedroom overnight. Night Mode dims the display and drops the fan so nothing wakes you.
Who this is best for
Best suited to bedrooms, nurseries, home offices, studies and medium living areas up to around 46 m² – anywhere you want genuine filtration performance without a bulky appliance dominating the room.
Particularly worth considering if you're managing hay fever or asthma triggers, sharing a home with pets, cooking in an open-plan space, or dealing with bushfire smoke through summer.

Sees what you can't
✔SMART VOC SENSING
Most air purifiers only measure particles. The SP3i also tracks total volatile organic compounds – the gases released by cleaning products, paint, new furniture, cooking and adhesives. You get a real picture of your air, not half of one.
✔AUTO MODE THAT ACTUALLY REACTS
Built-in PM2.5 and gas sensors feed Auto Mode continuously, so fan speed rises when you start cooking and settles again once the air clears. No dial-watching required.
✔GLANCEABLE AIR QUALITY
An indicator built into the air outlet shows current pollution levels across five colours, from blue for excellent through to red for poor, with a subtle animation while it's actively cleaning.
Superior filtration
:quality(90)/https://www.sleepsolutions.com.au/media//wysiwyg/Products/Blueair/SP3I/feature-5.jpg)
✔7-STAGE HEPASILENT™ FILTRATION
HEPASilent™ pairs mechanical filtration with an electrostatic charge, so particles are drawn to the filter rather than forced through it. That means 99.97%² capture down to 0.1 microns – smoke, dust, pollen, pet dander, mould and dust mite allergen – at lower noise and lower power draw than conventional HEPA.
✔ODOURS BROKEN DOWN, NOT MASKED
OdorFence™ uses bio-based enzymes and minerals to break odour and gas molecules apart, removing up to 10x³ more odour than a standard carbon layer. Useful for cooking smells, pets, smoke and damp.
✔EFFICIENT BY DESIGN
36 W at full tilt, and a fraction of that on lower speeds – comparable to a household light bulb, so it's affordable to leave running.
:quality(90)/https://www.sleepsolutions.com.au/media//wysiwyg/Products/Blueair/SP3I/feature-2.jpg)
Smartest display
✔WAKES AS YOU APPROACH
A dot matrix screen with top-facing controls detects motion and lights up as you walk past – wave a hand above it and the panel illuminates. No stooping, no hunting for a button.
✔ANIMATIONS THAT MEAN SOMETHING
Settings are shown through small animations rather than cryptic icons, so the current mode is obvious at a glance.
✔DISPLAY LOCK
Lock the panel to stop settings being changed by curious kids, pets or a stray elbow.
A little maintenance, a lot of comfort
:quality(90)/https://www.sleepsolutions.com.au/media//wysiwyg/Products/Blueair/SP3I/feature-6.jpg)
✔ONE FILTER, UP TO 12 MONTHS
A single quick-swap filter, no tools needed. The patent-pending design doubles the usable life compared with the previous generation, so you're replacing it roughly once a year.
✔REALTRACK TECHNOLOGY®
Rather than counting down from a fixed date, RealTrack® calculates remaining filter life from actual fan speed, run time and pollution levels. The indicator turns red when it's genuinely time, and the app will tell you too.
✔WASHABLE PRE-FILTER
The fabric pre-filter catches dust, hair and pet dander before it reaches the main filter, extending its life. Vacuum it or rinse it and put it back.
Smart control in the Blueair app
Take control of your air
Set a fan speed, hand over to Auto or Night Mode, and lock the display to keep your settings put.
Schedules that fit your routine
Wake up to fresh air, run harder through peak hours, and ease off while you're out.
Filter lifetime tracking
Track remaining filter life against real pollutant levels, and get an alert when it needs replacing.

Good quality, price and service.

Purchased a IONMAX ION632 Desiccant Dehumidifier from Sleep Solutions a month ago. I’m very happy to report that the unit is performing well above our expectations. We live on the East Coast in Tasmania where the humidity is quite high even in winter . We had issues with puddles of water on the window ledges and we glass on the windows, but running the Dehumidifier overnight completely solved this ! Dries out the bathroom quickly including the towels. Another bonus it gently warms the room as it works . The unit has worked faultless . Sleep Solutions were easy to deal with online , unit arrived quickly and well packaged. Thanks , Alan .

I bought a Sheridan Deluxe Dream medium profile pillow from Sleep Solutions. The service was outstanding. I placed the order online and it arrived the following day. The price was extremely competitive, too. Very impressive! I would not hesitate to recommend Sleep Solutions.

I later found the product I purchased 1/3 cheaper after looking elsewhere. Lost $80

Nifty little device that has helped me get off to sleep & block out other house & street noise. I love the thunderstorms sound. Quite compact & lightweight so I hope to take it travelling. Lots of different sound options which is great. Has rain sounds which I love but it they're more like a trickle sound rather than rain per se. Just an observation!
