Blueair DreamWell H38i Humidifier 3.8 L 48 h Run Time

Bedroom humidifier by Blueair, model DreamWell H38i, with 360-degree InvisibleMist technology: water evaporates through a wick, so there is no visible mist and no white deposits. The 3.8-litre tank allows up to 48 hours of operation in automatic mode and can be filled from the top or with a bucket. It includes three mood-light tones and a stone for aromas.

When choosing a humidifier it is worth comparing the humidification output in ml/h or litres per day and the declared room size, the tank volume and the run time it allows, the technology (ultrasonic, evaporative or steam) and the maintenance it requires: ultrasonic units need soft water or a demineralisation cartridge to avoid white dust, while evaporative units use a wick filter that is replaced periodically. The appliance needs a stable surface, clearance from walls and furniture and a 220-240 V socket; relative humidity is best monitored with a hygrometer and kept between 40 and 60 %.

The data shown comes from the documentation published by the manufacturer; in case of divergence the official product datasheet prevails. The appliance is covered by the two-year statutory warranty for defects under German law (§§ 434 ff. BGB).
