How they stack up

Air Wick Essential Mist Starter Kit, Diffuser + 1 Refill, Lavender and Almond Bl

The Air Wick Starter Kit is unique in its cordless, battery-powered operation, making it more portable than the ASAKUKI and LEVOIT models. However, it's limited to 1 refill and offers only 3 fragrance intensity settings, unlike the Ultimate Aromatherapy Diffuser's 10ml oil bottles or the EQUSUPRO's 150ml tank. While it's simple to use and has a long-lasting refill, it lacks the timer and lighting features of the more feature-rich competitors like Homeweeks and Earnest Living.

ASAKUKI Essential Oil Diffuser for Home, 500ML Aromatherapy Diffuser Humidifier

The ASAKUKI Essential Oil Diffuser stands out with its large 500ml tank offering up to 16 hours of runtime, far exceeding the 150ml to 300ml capacities of competitors like EQUSUPRO and Homeweeks. While it lacks adjustable mist intensity without the remote, it surpasses the LEVOIT in runtime and offers a more comprehensive lighting system with 7 LED settings compared to the LEVOIT's absence of lighting features. Its remote control functionality also gives it an edge over the basic models like Earnest Living and Air Wick.
