ASAKUKI Dew Plus review

The ASAKUKI Dew Plus is the value pick on this list. ASAKUKI lists it at $28.99, with the light wood color on sale at $23.19 when we checked, and the product page shows free shipping, 30-day returns and a warranty of 1 year that you can extend to 2 years through an online form. The 300 ml tank is more than four times the Vitruvi Stone's 70 ml, and the unit has a 1H, 3H and 6H timer, seven LED colors and an auto shut-off when the water runs out. ASAKUKI rates it at 23 dB and for bedrooms and living spaces of up to 250 square feet. The trade-offs are materials and consistency: the shell is PP plastic with a wood-grain finish, and the spec sheet lists a 10-hour run time while the feature list says 12 hours. For a bedroom or office it does the job at a fraction of the price of the ceramic units. Larger rooms need the Vitruvi, Saje or a nebulizer.
