Old carpet, a kitchen that has cooked a thousand other dinners, a bathroom with no window. You cannot replace any of it, so the realistic move is to add something you do want to smell. A 100 ml tank putting out roughly 20 ml an hour is enough to change how a bedroom or a small lounge actually smells, rather than just scenting the air directly above it.
It is about 15 cm tall and runs off USB, so it works from a laptop, a power bank or a plug adapter. That makes it as useful on a desk at work or in a car as it is at home.
A seven-colour LED underneath can be left on a single colour or cycled, and turned off entirely if you only want the mist. At night on a low setting it works as a very soft night light, which is a gentler way to find the bathroom than the overhead.
The auto shut-off when the water runs low is the feature that lets you leave it running without thinking about it, and it is the one that cheap diffusers skip. Two modes let you choose constant or intermittent mist depending on how strong you want it.
This suits students, share houses, first apartments, desks at work and anyone who finds their place stuffy. It is also a kind gift for someone sleeping badly, especially alongside the white noise machine elsewhere in this guide.
Add a small set of oils and it is complete rather than a device they have to go shopping for. Worth mentioning when you give it: use water and a few drops of oil only, never oil on its own, and rinse the tank occasionally or the scents start to blend into something odd.
