Sans True HEPA Air Purifier (Midnight, Large)

How often do I need to replace the filters?

Filter replacement depends on usage and air quality conditions. The onboard indicator alerts you when replacement is needed, typically every 6-12 months for the HEPA filter and pre-filter. The activated carbon layer may need replacement more frequently in homes with heavy cooking odours or smoke exposure. Genuine replacement filters can be swapped in under 60 seconds using the simple access panel.

Will this purifier work effectively in my 1,500 square foot flat?

Yes, this unit covers up to 1,854 square feet, so it will effectively purify air throughout your entire flat. The powerful 45-watt motor ensures proper air circulation even in open-plan layouts. Smart sensors will automatically adjust fan speeds based on your specific air quality conditions, maintaining optimal performance without wasting energy.

How loud is the purifier during normal operation?

Normal operation produces minimal noise, with sleep mode reducing levels to just 35dB - quieter than a whisper. Even at higher fan speeds, the unit remains considerably quieter than most air purifiers. The advanced motor design and sound-dampening materials ensure you can run it continuously without disrupting conversations, sleep, or daily activities.

Does the UV-C light produce harmful ozone?

No, this purifier is CARB certified for zero-ozone emissions. The UV-C light operates in an enclosed chamber within the unit, sterilising the filter area without releasing ozone into your living space. This internal design meets California Air Resources Board standards for electrical safety and air quality, ensuring safe operation in homes with children and pets.

Can I control the purifier remotely or through an app?

This model uses touch controls on the unit itself rather than app connectivity. The simple button interface allows you to adjust fan speeds, activate sleep mode and monitor the colour-coded air quality indicator. The auto-mode feature means the unit largely manages itself, automatically adjusting performance based on real-time air quality readings.

What types of odours will the activated carbon filter remove?

The heavy-duty activated carbon layer effectively absorbs cooking smells, cigarette smoke, pet odours and volatile organic compounds (VOCs) from household products. It's particularly effective against lingering odours from frying, strong spices and smoke from wildfires or nearby sources. The carbon layer works continuously to neutralise odour molecules as air passes through the filtration system.

Is the child lock feature reliable for homes with toddlers?

Yes, the electronic child lock prevents accidental changes to settings by curious toddlers or pets. Once activated, the lock disables all touch controls whilst maintaining current operation settings. This safety feature ensures consistent air purification without interruption from small hands, whilst still allowing you to easily unlock and adjust settings when needed.

What warranty coverage comes with this air purifier?

The unit includes a comprehensive 5-year manufacturer warranty covering defects and performance issues. Additionally, you receive a 30-day risk-free trial period to test the purifier in your home environment. This extended warranty coverage demonstrates the manufacturer's confidence in build quality and provides long-term peace of mind for your investment.
