The Vitruvi Stone turns up in seven of our eight sources, and three of them rank it first. HGTV's Theresa Holland named it Best Overall in September 2026. Good Housekeeping's Wellness Lab gave it the same title after it 'scored the highest marks across every category' of the lab's tests, and Healthline put it at the top of its list too. Even Wirecutter, which has backed a $20 URPOWER since 2017, names the Stone as its upgrade pick.
Scent output beats what the size suggests. In HGTV's testing the scent was noticeable beside the unit right away and across a large room within about an hour, and the tank ran the full 8 hours on the intermittent setting. Vitruvi rates it for 500 square feet. Homes & Gardens gave it 4 out of 5 for scent strength and found it quiet enough to run in a home office.
At bedtime, the cheaper picks can't match it. Wirecutter calls it 'one of the few diffusers with a truly subtle indicator light' and its choice for running while you sleep. It shuts itself off when the timer ends or the water runs out, so a forgotten diffuser never sits there running dry.
The hand-molded ceramic cover is why people buy it as decor. HGTV praises the 'sturdy, well-made design', and TechGearLab says the cover 'looks fantastic'. Left on a shelf, it passes for a piece of pottery. Vitruvi lists it at $129.99, and the white version was on sale for $103.99 on vitruvi.com in October 2026.
What It Won't Do
The tank is small. Vitruvi rates its 70 ml for 4 hours of continuous mist, and Wirecutter found that two layers of lids make refilling more annoying than it should be. The Spruce found crevices inside the tank that are hard to clean, and Homes & Gardens notes the controls sit on the back where they're tricky to reach. You get two run settings, no remote and no mist control. For $129.99 list, that's a lot less tank than the ASAKUKI gives you for $35.99.
Two separate 2026 roundups chose the ASAKUKI 500ml. Homes & Gardens' Ottilie Blackhall named it the best all-rounder in August 2026 and scored its value 5 out of 5. A month later, HGTV picked it as Best for Large Rooms. ASAKUKI models also turn up in Good Housekeeping, TechGearLab and Reviewed, which makes it the most recommended budget brand in our research.
The tank sells it. It holds 500 ml, about seven times the Vitruvi's water, and ASAKUKI rates it for up to 16 hours, enough for a full night and the next morning. HGTV added 20 drops and could smell it across a large room after about an hour. Homes & Gardens found it 'completely silent', and ASAKUKI rates it under 23 decibels.
Its controls beat the Vitruvi's, too. A remote with a 16.5-foot range sets 1, 2 or 3-hour timers, and the seven-colour light switches off without stopping the mist. ASAKUKI lists it at $35.99 on its own store, and its Amazon listing averages 4.3 stars from 72,771 ratings.
What It Won't Do
It looks like what it is, a plastic diffuser, and no reviewer praised its design. HGTV found the mist shoots out at a diagonal instead of straight up, so give it room away from walls and wood furniture. Homes & Gardens found condensation collects around the base and needs wiping. The warranty is 1 year unless you register the diffuser for a second.
