## Why we chose it

At under 0, the Classic300S is the most accessible pick here: a BPA-free food-grade polypropylene tank with a top-fill design that prevents growth from residual standing water at the bottom. App control lets you set a precise humidity target rather than running continuously. Levoit discloses the plastic grade on the product page. No essential oil slot on the 300S model.
