EQUSUPRO 150ml Black Metal Essential Oil Diffuser

4.6

3 sources2 derived$16.99as of Aug 1

The EQUSUPRO is a 150ml ultrasonic diffuser in a black metal shell, priced at the bottom of the category. It mists continuously or on a 30-seconds-on, 30-off cycle, runs whisper quiet, and adds a seven-colour LED nightlight. There is no app, no scheduling and no smart timer; the controls are buttons on the unit. TechGearLab's aromatherapy diffuser roundup ranks it eighth, praising its vivid light patterns but faulting its inconsistent, underwhelming diffusing performance, and the two video reviews in its citation list both land at 4.5.

Strengths

— Compact design suitable for small spaces
— Black metal aesthetic with modern appearance
— Easy to use with simple controls and LED lighting

Watch-outs

— Limited water capacity at 150ml
— No smart connectivity or app control features

Ranked #2 in Best Essential Oil Diffusers

Ultimate Aromatherapy Diffuser & Essential Oil Set

4.5

1 sourceall derived$19.95as of Aug 1

EUCATAPE's Ultimate Aromatherapy Diffuser & Essential Oil Set is a modern ultrasonic diffuser that atomizes essential oils through wave diffusion technology, with no heat involved. Wirecutter reviewers praised the strong mist output and the 10 therapeutic grade oils included in 10ml amber jars. The unit runs 7 ambient light modes across 14 combinations, plus 4 timer settings and auto shutoff. The body is BPA-free plastic with a printed wood grain design that some will find unappealing, and those 10ml bottles run out fast.

Strengths

— Produces strong mist using ultrasonic wave diffusion technology
— Includes 10 therapeutic grade essential oils in 10ml amber jars
— Features 7 ambient light modes with two intensity settings for 14 light combinations

Watch-outs

How they stack up

EQUSUPRO 150ml Black Metal Essential Oil Diffuser

The EQUSUPRO diffuser's compact design and black metal aesthetic distinguish it from the larger ASAKUKI and LEVOIT models, though its 150ml tank capacity is significantly smaller than ASAKUKI's 500ml. Unlike the Ultimate Aromatherapy Diffuser, it doesn't include essential oils, and compared to the Art Glass Diffuser, it lacks the premium glass construction and more advanced timer options. It's best suited for those who prefer a sleek, basic model without smart features.

Ultimate Aromatherapy Diffuser & Essential Oil Set

The Ultimate Aromatherapy Diffuser sets itself apart by including 10 therapeutic-grade essential oils in 10ml amber jars, a feature not found in the ASAKUKI or EQUSUPRO models. While it offers strong mist output and 14 light combinations, it's made of BPA-free plastic with a wood grain design that some find unappealing, unlike the ceramic or glass options from Earnest Living and Art Glass Diffuser. Its timer and auto-shutoff features are also more advanced than the basic models like Homeweeks.
