By Bikram Nath · Updated 2026-10-03 · How we pick · Affiliate disclosure: links earn a small commission
What's the best humidifier to buy in India?
The Reffair Caligo 500 is our top humidifier for a bedroom. Its listing states cool and warm mist, a 4 L top-fill tank, an LED display of room humidity, an auto mode that stops and restarts misting on its own, two mist levels, a 12-hour timer and a 1-year warranty.
The other six do not list warm mist. They range from an 800 ml USB-powered desk unit (Excacia) to a 6-litre tank (Costar), and differ on runtime, stated noise, whether you can add essential oils, and warranty.

Editor's read
Five of the seven list a 1-year warranty, and the Reffair's can be extended by registering on the brand's website. The Costar listing states no warranty term, and the Dr Trust listing says "No Warranty".
— Bikram, editor
Editor's take
Match the tank to how long you want it to run unattended: the Costar for the fewest refills, the raydrop or AGARO for a standard bedroom, the Excacia only for a desk. If you want warm mist or automatic humidity control, the Reffair is the only one here with either.

How we picked these humidifiers
Every pick on this page is matched to its exact Amazon India listing, and the specifications, warranty terms and features on each card come from that listing; a brand's own claims are attributed to the brand. We don't physically test the products in our guides, and we don't link to Amazon search results. Prices shown come from Amazon's data with the time they were fetched; the price at checkout can differ.
Our editorial process is one person — Bikram, based in Pune. The order of products on this page reflects our editorial ranking only. No brand paid for a place in this ranking. Each ranked pick earns us money only through its Amazon affiliate link — clicking through earns a small commission, your price stays identical.
Buying humidifiers in India — what to check
- Warranty:check that the listing states an Indian warranty and what it covers. Imported (grey-market) units may not be serviced by the brand's Indian service centres.
- Delivery and returns: Amazon shows the delivery date for your pincode and the return policy on each product page. Check both before ordering, especially if the humidifier is a gift or needed by a date.
- Keep the invoice: some brands ask you to register the product after purchase. Keep the Amazon invoice and read the warranty card that comes in the box.
What to Look For
- 1.Cool or warm mist: only the Reffair Caligo 500 offers warm mist as well as cool. Reffair's own listing says warm mist helps keep a room comfortable in winter but is not a space heater. Warm mist means heated water, so keep such a unit out of children's reach.
- 2.Tank and runtime: the Costar holds 6 L (up to 100 hours on its lowest setting), the Dr Trust 4.5 L (12-22 hours), the Reffair 4 L, the AGARO and raydrop 2.5 L (raydrop: up to 30 hours on low), the ROSEKM 2 L (its listing says one fill lasts overnight) and the Excacia 800 ml.
- 3.Filling: the Reffair, Costar and raydrop list top-fill designs, which you fill from above without carrying the unit to a tap. The other four listings do not say.
- 4.Noise: only two listings give a figure — under 28 dB for the raydrop, whose indicator light also auto-dims, and up to 38 dB for the Dr Trust. The AGARO, Costar and Reffair describe themselves as quiet without a number.
- 5.Essential oils: the Reffair, raydrop and Dr Trust are built to take essential oils; the Costar listing says not to add essential oils or fragrance to its tank.
- 6.Water: an ultrasonic humidifier turns whatever is dissolved in the water into mist, so hard tap water can leave white dust on furniture. Distilled or RO water reduces it.
