Green Air Classic Air Purifier (Green, SFA 2.2)

How often should I replace the filters in this air purifier?

The activated carbon filter typically needs replacement every 6-12 months depending on usage and air quality conditions. HEPA filters can last 12-18 months with regular cleaning. Monitor the app for filter status indicators and replace when performance drops. Heavy use in polluted environments may require more frequent changes whilst light residential use can extend filter life.

Is the ozone generator safe for continuous use around people and pets?

Ozone generators should be used with caution as ozone can irritate respiratory systems at high concentrations. This unit allows you to control ozone output through the app. Use ozone mode when rooms are unoccupied then switch to standard HEPA filtration when people return. Always ensure adequate ventilation and follow manufacturer guidelines for safe ozone levels.

What maintenance is required to keep this purifier running efficiently?

Regular maintenance includes cleaning the pre-filter monthly, checking and cleaning the HEPA filter every 3 months and replacing the activated carbon filter as needed. Wipe down the exterior weekly and ensure air intake and outlet vents remain unobstructed. The app provides maintenance reminders and tracks filter life to help you maintain optimal performance.

Can this purifier handle cigarette smoke and cooking odours effectively?

Yes, the activated carbon filter excels at removing smoke particles and cooking odours. The ozone generator provides additional odour elimination by breaking down odour molecules at source. For heavy smoking environments, consider more frequent carbon filter replacement. The large coverage area ensures smoke and cooking smells are quickly processed and neutralised.

How loud is this air purifier during operation?

Noise levels vary by fan speed setting which you can control through the app. Lower speeds operate quietly for bedroom use whilst higher speeds generate more noise but provide faster air cleaning. The app allows you to schedule quiet operation during sleep hours and boost cleaning when noise isn't a concern. Most users find the noise acceptable for the cleaning performance provided.

What room sizes work best with this 4500 square foot coverage?

This purifier works effectively in rooms up to 4500 square feet but performs best when sized appropriately. For maximum efficiency, use in spaces around 2000-3000 square feet. Larger spaces benefit from the high air circulation rate whilst smaller rooms get multiple air changes per hour. Open floor plans and high ceilings may require positioning for optimal air flow patterns.

Does the app work with both Android and iOS devices?

The Green Air app supports both Android and iOS platforms allowing smartphone and tablet control. Download from Google Play Store or Apple App Store then connect via your home WiFi network. The app provides real-time air quality monitoring, scheduling functions, filter status updates and remote control capabilities. Ensure your router supports 2.4GHz WiFi for reliable connectivity.

What warranty coverage comes with this air purifier?

Green Air typically provides manufacturer warranty coverage for defects in materials and workmanship. Warranty terms vary by region and purchase date so check your documentation for specific coverage details. Register your product through the app or manufacturer website to activate warranty protection. Keep purchase receipts and follow maintenance guidelines to ensure warranty validity.
