How it works

  1. 1Base = 40 m² × 0.6 = 24 L/day (standard condition)
  2. 2Normal room: no scenario uplift
  3. 3Pick the next retail tier → 25 L/day (buy bigger, not smaller)

The rated capacity on the nameplate is measured at 30°C / 80% RH. Data quoted at 27°C / 60% RH can be roughly half the real output — always compare the standard condition figure.

Multi-floor homes should use one unit per floor; a basement or a room storing books/instruments needs the 0.8-1.0 L/m² range. For laundry drying, place the unit below the clothes.

Target humidity is 45-60%: too low dries wood and skin. Prefer continuous drainage (hose to a floor drain) for basements; a water tank needs emptying several times a day in the rainy season.
