Sans True HEPA Air Purifier (White, Large)

How often do I need to replace the filters?

Filter replacement depends on usage and air quality conditions. The built-in indicator will alert you when replacement is needed, typically every 6-12 months for the HEPA filter and pre-filter. The activated carbon layer may need replacement every 3-6 months in homes with heavy cooking or smoking. Replacement takes under 60 seconds using genuine Sans filters.

Is this air purifier suitable for people with severe allergies?

Yes, the medical-grade True HEPA H13 filter captures 99.9% of particles down to 0.1 microns, including common allergens like pollen, dust mites, pet dander and mould spores. The UV-C sterilisation provides additional protection against airborne pathogens. Many users with seasonal sensitivities report significant improvement in air quality and reduced allergy symptoms.

How loud is the unit during normal operation?

The Sans air purifier operates at different noise levels depending on fan speed. Sleep mode runs at whisper-quiet 35dB, comparable to a library. Normal operation ranges from 35-55dB depending on auto-mode settings. The advanced motor design eliminates vibration and mechanical noise, making it suitable for bedrooms and quiet spaces.

Can this handle pet odours and cigarette smoke effectively?

The heavy-duty activated carbon layer specifically targets molecular-level odours including pet smells, cooking odours, cigarette smoke and VOCs. The pre-filter captures pet hair and larger particles before they reach the HEPA filter. Many pet owners report significant reduction in airborne dander and household odours within hours of operation.

What room size is this air purifier designed for?

This unit effectively covers up to 1,854 square feet, making it suitable for large living rooms, open-plan areas, master bedrooms or small offices. The powerful 45-watt motor ensures complete air circulation every hour. For optimal performance in larger spaces, position the unit centrally with adequate clearance around all sides.

Does the UV-C light produce harmful ozone?

No, this unit is CARB certified for zero ozone emissions. The UV-C light operates within an enclosed chamber inside the filtration system, preventing ozone production whilst maintaining filter hygiene. The design meets California Air Resources Board standards, ensuring safe operation in homes with children and pets.

How does the smart auto-mode actually work?

Built-in air quality sensors continuously monitor particulate levels and automatically adjust fan speeds based on real-time conditions. The colour-coded AQI indicator provides visual feedback: blue for good air quality, orange for moderate and red for poor. This intelligent system conserves energy whilst maintaining optimal air quality without manual intervention.
