Verdict

The Greenote Air Purifier (AP10) features a 3-in-1 Japanese Toray H13 True HEPA filtration system and a 360-degree aerodynamic design, capturing 99.97% of airborne microparticles, allergens, and kitchen odours down to 0.3 microns. It efficiently covers spaces up to 430 square feet (40 m²), refreshing the air up to five times per hour with an energy-efficient power consumption of just 0.24 kWh per day. Prominent pros include an ultra-quiet 22dB sleep mode powered by advanced Nidec turbocharging technology, user-friendly touch controls with 4 fan speeds, a 2/4/8-hour timer, and a built-in filter replacement indicator. However, its notable cons include a complete lack of modern smart features or companion mobile app compatibility, and its smaller footprint means it experiences a noticeable drop in purification efficiency if operated in rooms exceeding its 430 sq. ft. rating.
