Which is better for a large living room?

The Stone Diffuser. It covers up to 500 sq. ft. versus 400 for the Now, and its 1 fl. oz. per hour output is strong for an open room. The Now's larger tank suits smaller rooms where you want long, low-output runs.

Which runs longer on one fill?

The Now. Its 150 ml tank runs up to 7 hours continuous or 14 hours intermittent. The Stone's 70 ml tank runs 4 hours continuous or 8 hours intermittent.

Is the Stone Diffuser worth stepping up to?

If looks and scent strength matter, yes. The ceramic body, wider coverage and much larger review base make it the safer pick. If you mainly want long run time on a budget, the Now does that job.

Both are ultrasonic and described as quiet. The Now's listing calls it extremely quiet; the Stone's reviews mention a soft, subtle sound. Neither uses heat, so neither has a fan loud enough to disturb sleep.

Do either include essential oils?

No. Both need tap water and your own essential oils. The Stone's reviews specifically note that scents must be bought separately.

Which has better build quality?

The Stone's matte ceramic cover draws consistent praise for quality, though some newer units feel lighter. The Now uses a bamboo cover and base and carries a 1-year warranty.

Vitruvi Stone Diffuser vs Now Ultrasonic Real Bamboo Diffuser

The Vitruvi Stone Diffuser is the better buy for most people. It has a larger tank, longer continuous runs, a wider coverage area, and a matte ceramic body that owners describe as decor-quality. The Now Real Bamboo costs far less and runs longer per fill, but its 3.9 rating from 39 reviews is thin, and the bamboo cover looks more like an appliance than a piece of pottery. Buy the Stone if scent output and looks matter; buy the Now if you want a cheap, long-running diffuser for a bedroom or office.

Choose the Stone Diffuser if you want a sculptural ceramic diffuser with strong scent output, a 500 sq. ft. reach, and an optional soft glow light.
Choose the Now Ultrasonic Real Bamboo if you want a low-cost, long-running diffuser with rotating colored LED lights and a 1-year warranty.
