Xiaomi Smart Air Purifier 4 Lite (Global Version)

Breathe cleaner, quieter air—minus the bulk—with the Xiaomi Smart Air Purifier 4 Lite (Global Version, model AC‑M17‑SC / BHR5274GL). Optimized for small to medium rooms (25–43 m²) with a compact footprint (~24 × 24 × 53 cm), it delivers a powerful 360 m³/h Particle CADR, circulating over 6,000 L of purified air per minute for rapid air turnover—perfect for bedrooms, offices, or nurseries.

At its core is Xiaomi’s proprietary High‑Efficiency Filter, combining mechanical melt‑blown fibers with electrostatic charge. Tested to remove 99.97% of particles ≥ 0.3 µm, it relies on less-dense fiber spacing to reduce airflow resistance—offering lower noise and power usage compared to standard HEPA filters.

Filtered air is intaken in 360°, pushed through a triple-layer cartridge (mesh pre-filter + high-efficiency media + ~450 g activated carbon), and expelled upward in a sleek tower airflow design. The filter surface area is approximately 20,000 cm², with activated carbon content 1.8× greater than the Mi Air Purifier 3C—boosting VOC and odor control.

Operation is flexible and modern: a touch-enabled LED panel displays PM2.5, temperature, humidity, Wi‑Fi and mode status, with a color-coded ambient light strip for real-time air quality indication. Noise ranges from a quiet 33.4 dB(A) in Night mode to ≤ 61 dB(A) at maximum speed—efficient yet unobtrusive.

With smart control via Mi Home / Xiaomi Home app, set schedules, monitor air quality, receive filter maintenance alerts, and trigger remotely. Also supports voice assistants like Google Assistant and Amazon Alexa, depending on region. ** **

This “Lite” model does not include the negative‑ion generator found in the Xiaomi 4/4 Pro, aligning it more closely with allergy-friendly preferences—and every unit is TÜV Rheinland Allergy Care certified for safe, effective filtration.
