Blueair Blue Max 3350i (Stockholm Fog, 86m²)

What room size is the Blue Max 3350i suitable for?

The Blue Max 3350i effectively covers up to 86m² on high speed, cleaning the entire space in 30 minutes. For medium rooms of 36m², it completes a full clean cycle in approximately 12.5 minutes. This makes it ideal for large bedrooms, open-plan living areas, or office spaces. The unit's powerful airflow ensures multiple air changes per hour even in larger spaces.

How quiet is this air purifier during operation?

The unit operates at just 23dB on low fan speed, which is quieter than a whisper and holds official Quiet Mark certification. This makes it perfect for bedroom use without disturbing sleep. Even on higher speeds, the advanced motor design and aerodynamic engineering keep noise levels minimal - 50% quieter than previous Blue models whilst maintaining powerful cleaning performance.

What particles and pollutants does the HEPASilent filter remove?

The HEPASilent dual filtration system removes at least 99.97% of airborne particles down to 0.1 microns. This includes viruses, bacteria, smoke, pet dander, pollen, mould allergens and dust. The integrated carbon filter also traps light household odours from smoking, pets and cooking. The 4-stage filtration process ensures comprehensive air cleaning for healthier indoor environments.

How do I control the air purifier remotely?

The Blueair app provides complete remote control via WiFi connection. You can monitor real-time air quality, adjust fan speeds, set custom schedules and use geofencing to automatically activate when you arrive home. The app also features RealTrack filter monitoring for accurate replacement timing. Voice control works with Alexa and Google Assistant for hands-free operation.

How often do I need to replace the filters?

The HEPASilent combination filter typically lasts 6-9 months depending on usage and air quality conditions. The RealTrack feature in the Blueair app monitors actual filter condition and provides accurate replacement notifications based on real usage rather than just time elapsed. This ensures optimal performance whilst avoiding premature filter changes, saving money and reducing waste.

What's the difference between this and previous Blue models?

The upgraded Blue Max series delivers 83% faster cleaning and 50% less noise compared to previous Blue models. The enhanced HEPASilent technology provides more efficient particle capture whilst the improved motor design reduces energy consumption. Smart features like app connectivity, geofencing and voice control are new additions that weren't available in earlier versions.

How much energy does the air purifier consume?

The Blue Max 3350i uses just 32W on high fan speed - less than a standard lightbulb. This efficient design means you can run it continuously without significant impact on electricity bills. The optimised motor and airflow system deliver powerful cleaning performance whilst minimising energy consumption, making it an economical choice for 24/7 operation.

Can I change the appearance to match my home décor?

The unit comes with a Stockholm Fog (light grey) pre-filter cover designed to complement modern interiors. Additional decorative covers in different colours and patterns are available separately, allowing you to customise the appearance to match your home's style. The Swedish-inspired design features clean lines and minimalist aesthetics that blend seamlessly with contemporary décor.
