Windmill Air Purifier (White, 30cm x 50cm x 54cm)

How often do I need to replace the HEPA filter?

The True HEPA filter typically requires replacement every 6-12 months depending on usage and air quality conditions. The Windmill Air app monitors filter life and sends notifications when replacement is needed. Heavy use in polluted environments or homes with pets may require more frequent changes, whilst cleaner environments can extend filter life. Regular filter replacement maintains the 99.97% particle capture efficiency.

Can this air purifier handle cigarette smoke and cooking odours?

Yes, the 3-in-1 filtration system effectively removes smoke particles and cooking odours. The activated carbon layer specifically targets volatile organic compounds (VOCs) and odours, whilst the HEPA filter captures smoke particles. The Boost mode provides enhanced cleaning power for heavy smoke or strong cooking smells. Users report significant improvement in air freshness within hours of operation.

How loud is the air purifier during normal operation?

The Windmill operates extremely quietly, with users reporting it's barely noticeable even on higher settings. Sleep modes are specifically designed for night-time use, with Whisper mode operating at near-silent levels. The white noise mode provides gentle background sound that many find soothing. The advanced fan design minimises noise whilst maintaining effective air circulation throughout the room.

Does the app require a subscription or ongoing fees?

No, the Windmill Air app is completely free with no subscription fees or ongoing costs. Once downloaded, you have full access to all features including real-time air quality monitoring, scheduling, remote control and filter life tracking. The app connects directly to your purifier via Wi-Fi and provides comprehensive control without any additional charges.

What's the difference between Eco mode and Boost mode?

Eco mode automatically adjusts operation based on current air quality readings, reducing power consumption when air is clean and increasing intensity when needed. This provides efficient, hands-off operation. Boost mode runs at maximum power for rapid air cleaning when dealing with heavy pollution, smoke or strong odours. Boost mode consumes more energy but delivers faster results for challenging air quality situations.

Can I use this in a bedroom without disturbing sleep?

Absolutely. The purifier features two dedicated sleep modes designed specifically for bedroom use. Whisper mode operates virtually silently whilst maintaining air purification. White noise mode provides gentle background sound that can actually improve sleep quality. The display automatically dims during sleep modes and the unit continues effective air cleaning throughout the night without disruption.

How do I know if the air purifier is actually working?

The built-in laser sensor provides real-time air quality readings displayed through the app, showing AQI levels and particle concentrations. You can track improvements in air quality over time and see immediate responses when the purifier detects pollution. Many users notice reduced dust accumulation, fewer allergy symptoms and fresher-smelling air within days of use.

Is this suitable for people with severe allergies or asthma?

Yes, the True HEPA filtration captures 99.97% of particles including common allergens like pollen, dust mites, pet dander and mould spores. The medical-grade filtration meets strict standards for air purification. Users with respiratory conditions report significant improvement in symptoms. However, whilst highly effective for air cleaning, it's always best to consult healthcare professionals for specific medical conditions and treatment plans.
