The two largest evaporative coolers in this family, one with a stated airflow figure
SereneLife appears in one family here: evaporative air coolers.
A stated 2,900 m³/h airflow, on the SLACL25WHGY — the only evaporative cooler in this family with a published volume figure, alongside coverage up to 84 m².
A genuine mid-size option, the SLACL5LWH, at 5 L and 1,000 m³/h, sitting between the compact Cecotec and the large SLACL25WHGY.
Neither model is a substitute for a compressor air conditioner in a humid room — both cool by evaporation, which loses effectiveness as ambient humidity rises.
Portable 4-in-1 AC with heat, 8,000 BTU ASHRAE / 5,000 BTU DOE, 350 sq ft, 880 W, 270 m (886 ft)³/h, R32, castors, window kit
A portable four-in-one air conditioner with a heater mode, rated 8,000 BTU ASHRAE and 5,000 BTU DOE for 350 square feet.
Best for: A room that needs cooling in summer and some warmth in spring, where a window is available for the hose

25 L tank · 2,900 m (9514 ft)³/h airflow · up to 84 m (276 ft)²
The largest tank in SereneLife's evaporative range: a 25 L reservoir with four included ice packs, rated for rooms up to about 84 m (276 ft)². SereneLife publishes 80 W power draw, roughly 2,900 m (9514 ft)³/h airflow, three speeds, two modes, 60/120° oscillation, a 1–12 hour timer, and 65 dB or lower noise, on 360° casters with a carry handle.
Best for: A living room or larger space in a dry climate, for buyers who'd rather refill a tank every few days than every few hours.
≈ $120
5 L tank · 80 W · 1,000 m (3281 ft)³/h airflow
A tower-style evaporative cooler with a 5 L dual-fill tank, four reusable ice boxes, and a washable dust filter. SereneLife publishes 80 W power draw, 1,000 m (3281 ft)³/h airflow, three speeds, three modes (Normal, Natural, Sleep), 60° oscillation, and under-60 dB operation, controlled by remote or a top touch panel.
Best for: A bedroom or home-office desk in a dry or moderate climate, where the tower's small footprint matters more than long runtime.
