Frequently asked questions
What capacity dehumidifier do I need for a bedroom in Mumbai during monsoon?
For a bedroom of 10–20 m² in a high-humidity coastal city like Mumbai, a 15 L/day compressor dehumidifier is the baseline. Increase to roughly 20 L/day if you are on the ground floor, because rising damp adds about 30% to the moisture load.
Is a Peltier dehumidifier enough for an Indian home?
No. Peltier units sold under ₹5,000 extract less than 500 ml of water per day, which is insufficient for any real room in Indian monsoon conditions. Use a compressor-type dehumidifier rated in litres per day at 30°C and 80% RH.
Should I run an air conditioner in dry mode instead of buying a dehumidifier?
AC dry mode helps when the room is also warm, but it cools the air at the same time and is less efficient at humidity removal during cool, rainy weather. A standalone dehumidifier removes moisture without lowering the temperature, which matters in cool monsoon spells below 26°C.
Does ground-floor living change the dehumidifier capacity I need?
Yes. Ground-floor flats face higher moisture from rising damp through walls and floors, so the recommended capacity is increased by about 30%. Flats on the 4th floor or higher can use slightly smaller capacity, around 10% less than the base figure.
What humidity level should I target indoors during the monsoon?
Aim for 40–60% relative humidity, measured with an inexpensive hygrometer. Below 40% is too dry for comfort and respiratory health; above 60% encourages dust mites and mould growth, which are the main reasons to run a dehumidifier in Indian homes.
