Description

The YESIDO EC39 4-in-1 Filter Air Purifier is a compact desktop air-cleaning device designed to improve indoor air quality in homes, offices, bedrooms, and other spaces of up to approximately 20 square meters. Featuring a comprehensive four-stage filtration system, the purifier combines a pre-filter, pet hair filter, H13 HEPA filter, and activated carbon filter to help capture airborne particles, pet hair, allergens, and unwanted odors, providing a more comfortable indoor environment. The built-in smart PM2.5 air-quality sensor continuously monitors particulate levels and provides easy-to-understand color alerts, with green indicating 0–75, yellow 76–150, and red above 150, allowing users to quickly understand the current air conditions. For added convenience, the EC39 supports dual aromatherapy, allowing compatible essential oils to add fragrance while the purifier operates. Its dual ball-bearing fans provide strong suction and airflow, with a rated speed of approximately 2400 RPM ±10%, helping circulate and purify air efficiently within the recommended coverage area. The purifier offers several operating options, including Sleep, Auto, Turbo, Child Lock, and Timer modes, allowing users to adjust operation according to their environment and preferences. Sleep mode is designed for ultra-low-noise operation, making it suitable for nighttime use while continuing air purification. An intuitive OLED touchscreen control panel provides clear information about PM2.5 levels, fan speed, and operating modes, making the device simple to monitor and operate. Constructed from durable ABS + PP material, the EC39 has a maximum output power of 10W and uses an AC 100–240V, 50/60Hz, 0.3A maximum input, with a DC 12V-1A maximum output. The composite filter measures approximately 152 × 100 × 148mm, allowing the purifier to maintain a relatively compact desktop footprint. Overall, the YESIDO EC39 combines four-stage filtration, real-time PM2.5 monitoring, aromatherapy, powerful airflow, multiple operating modes, touchscreen controls, and quiet sleep operation in a compact design, making it a practical choice for bedrooms, home offices, workspaces, and other indoor areas up to approximately 20 m².
