Home appliances
If walls sweat, clothes take two days to dry, or a cupboard smells musty, a dehumidifier often solves it faster than any paint or spray. But capacity numbers are quoted under lab conditions that overstate real-world performance, and compressor vs desiccant models behave very differently in cool rooms. This guide keeps the numbers honest.
Quick answer
For most homes, a compressor dehumidifier rated 10–20 litres a day.
Look for a humidistat, a continuous-drain option and a 2L or bigger tank.
Choose desiccant only if the room regularly drops below about 15°C.
Ignore lab-condition capacity claims; real output is lower.

The sticker price is one part of owning a dehumidifier. Adjust the numbers to your own usage and tariff to see the electricity cost a star rating actually translates to.
Units per year

Cost per year

Cost over 5 years
₹14,400 (≈$170)
Often more than the price difference between two models.
A humidistat cuts this sharply by cycling off once the room hits target humidity. Estimates only — actual consumption varies with ambient temperature, settings and unit condition. USD values are approximate.
Every new appliance already carries a brand warranty. An extended plan or AMC only adds value where it covers the parts that actually fail, with on-site service in your city — so read the cover, not the discount.

Usually not covered
Rule of thumb: a plan is rarely worth it if it costs more than ~15% of the product price, if the item is cheap to repair locally, or if the brand's own service network in your city is already strong.

Buy it locally
Sometimes the local dealer beats online on price, installation or the exchange offer. Tell us where you are and we'll list nearby stores. We don't rank or take money from any shop; results come from Google Maps.
The area you enter, or coordinates rounded to about 1 km if you use your location, are sent to Google Maps through Lovable to find places. Lookups are temporarily cached for up to 30 minutes.
Water removed per day, measured at 30°C / 80% humidity in a lab.
Why it matters
Real homes are cooler and drier than the lab — expect 50–70% of the rated figure.
What to check
A 10L/day unit suits one damp room; whole-floor damp needs 20L/day or more.
Compressor units condense moisture like an AC; desiccant units absorb it into a rotor.
Why it matters
Compressors are efficient in warm rooms but stall below ~15°C; desiccants work in the cold but use more power.
What to check
Cold, unheated room in winter? Compressor models barely extract anything there.
Sets a target humidity, usually 40–60%.
Why it matters
Stops the unit running all day; 50–55% is the comfort sweet spot.
What to check
Models without one run constantly and over-dry the air.
Collection tank capacity, and a hose outlet for non-stop draining.
Why it matters
A 2L tank on a 12L/day unit means emptying it six times a day — the hose matters more than the tank.
What to check
Check the drain outlet height; it drains by gravity, not a pump.
Typically 35–48 — like a quiet fan to a loud conversation.
Why it matters
Bedrooms and living rooms need the quieter end; check the lowest fan speed rating.
What to check
Compressor hum carries through floors at night; desiccants are often quieter.
A basic dust filter and a high-fan mode aimed at drying clothes indoors.
Why it matters
Laundry mode genuinely cuts indoor drying time in half in humid weather.
What to check
Filters need monthly washing — check it's easy to remove.
