Rank #6 in Best Humidifiers for Bedroom & Home 2026: 10 Ranked on Output
ROSEKM 2L Cool Mist Humidifier, 200ml/h, 4 Mist Levels
Price and rating as shown on Amazon when we collected them. Both change.
The ROSEKM is filterless, and that is its selling point: no cartridge to buy and replace, with a 2 litre tank, a quoted 200 millilitres per hour output, four mist levels, adjustable humidity control, a water level window and auto shut-off, at 950 grams in a 13 by 13 by 25.8 centimetre body.
Filterless matters because replacement filters are the recurring cost of most humidifiers and one more thing to run out of. A 24 hour runtime is named. At the time of collection it carried 10,258 ratings at 4.1 stars. Everything here comes from the Amazon listing rather than our own testing.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Absolutely incredible. Whilst it cannot cure really bad coughs, it certainly has made a huge difference. Humidity is what is required. Its quiet, effective, easy to use, easy to fill. A full tank can last at least 9 hours on the highest setting. The directional diffuser is effective. What incredible value and a really thoughtful company providing. We thought warm air might be better but realising as soon as the warm mist hits the air it will cool immediately. Having cool air is and has been a huge comfort. Cannot praise this item highly enough. Thank you RoseKM.”
Verified purchase“Bought this to help with dry eyes, as recommended by the hospital. I was surprised by the difference it made!It is very quiet while it’s running, I have it on all night every night. I notice the difference in the morning if I stay away from home. Easy to use, fill up from the tap. It has a setting where it decides itself what level it needs to be on (?) so all I have to do is press the on button once to turn it on and twice to turn it off. Idiot proof.Should also add that it’s so quiet I have to put my hand over it to see if it’s running as it’s so quiet I can’t hear it and the lights on it turn off after a few minutes so they don’t light up the bedroom. If you press the on/ off button once it shows the humidity level in the room.”
