A large-tank budget diffuser that does the whole job, with long runtime, scent, glow and a safe shutoff, plus the plastic build and simple controls the price implies.
Best for: Bedroom and office users who want set-it-at-night aromatherapy with runtime to spare, plus a soft night-light, without spending boutique-brand money.

Legitimate large-room HEPA cleaning with a strong owner track record. The open questions are price against equal-coverage rivals and the long-term filter bill.
Best for: Allergy and asthma households, pet owners, wildfire-smoke regions, and anyone who wants one purifier serving a big living area instead of several small units.
