Sterra Moon

The Sterra Moon True HEPA-13 Air Purifier is a powerful yet stylish solution for cleaner indoor air.

With its advanced 3-in-1 True HEPA-13 filtration system, it eliminates up to 99.97% of airborne pollutants, including pet fur, dust, smoke, bacteria, and allergens.

This medical-grade filter is the same standard used in hospitals for decontamination, ensuring top-tier air purification in your home.

Key Features:

• Triple-layer Medical-Grade HEPA-13 Filter: Sterra Moon uses a 3-in-1 filtration system consisting of a pre-filter, a True HEPA-13 filter, and an activated carbon layer. This setup effectively eliminates up to 99.97% of airborne particles as small as 0.3 microns, including allergens, dust, pet fur, mold spores, bacteria, viruses, and volatile organic compounds (VOCs) such as smoke and odors. The incorporation of activated charcoal helps neutralize odors from pets, cooking, and smoke, giving it an edge in odor control.
• Advanced UV-C Technology: Unique among many purifiers in its class, the Sterra Moon includes UV-C light to inactivate microorganisms, which further reduces indoor allergen levels and microbial contaminants. This adds a layer of microbial disinfection beyond just filtration.
• Real-time Air Quality Monitoring and Smart Controls: The device features a built-in air quality sensor with LED color indicators that reflect real-time air cleanliness. It also supports connectivity with a mobile app for remote control, timer settings, and filter lifespan monitoring. The purifier can integrate with smart home assistants like Google Assistant and Alexa for voice control and scheduling.

Performance and Coverage

• Coverage Area: It covers up to 615 square feet, making it suitable for master bedrooms, living rooms, home offices, and studio apartments. This coverage is competitive for a single-unit air purifier, capable of servicing medium to large rooms comfortably.
• CADR and Power Efficiency: The Clean Air Delivery Rate (CADR) is 280 m³/h, which is strong for its size and price segment. Energy consumption ranges from 2 to 45 watts, featuring low power usage without sacrificing performance. Noise levels vary between a whisper-quiet 20 dB at the lowest setting to a maximum of about 64 dB, remaining relatively quiet for household use.

Design and Usability

• Aesthetic and Controls: Sterra Moon boasts a sleek, modern, and cylindrical design available in multiple colors to fit various home décors. Controls are simple — one-touch operation and a tilt-sensitive eye-like control for fan speed adjustment. The smart app further enhances usability with remote operation and scheduling.
• Maintenance and Filter Life: Filters last between 6 to 12 months depending on air quality and usage, and the device notifies users when it’s time to replace the filter. Filters are easy to maintain and replace, making the device convenient to own.
