Verdict

The Olimpia Splendid 02064 Aquaria S1 20 P is a high-capacity portable dehumidifier capable of extracting up to 20 liters of moisture per 24 hours from large spaces up to 90 cubic meters. It stands out with a triple filtration air purification system—featuring an anti-dust pre-filter, an activated carbon filter for odors, and a HEPA filter effective down to 0.3 microns—alongside a large 5-liter semi-transparent water tank, a 24-hour timer, 3 fan speeds, and a motorized oscillation flap for flexible airflow. Key advantages include modern smart integration via built-in Wi-Fi (using the OS Home app), a sleek touchscreen control panel, a convenient laundry drying mode, an eco-friendly R290 refrigerant, and integrated transport wheels. However, notable drawbacks include real-world noise levels that some users find significantly louder than the advertised 38 dB, an app configuration process that feels unnecessary or complex to some, and the inherent operational heat output that can noticeably warm smaller rooms during prolonged use.
