What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Coway AP-1512HH Mighty
HouseFresh's chamber test rates the Coway AP-1512HH Mighty a strong cleaner — clearing incense smoke in a 728 cu ft lab in 26 minutes at top speed with a 247.7 CFM dust CADR — but flags it as unusually power-hungry (75.3W) and now dated, with better-value rivals available. (1 sourced review, 1 lab-tested.)
Praised: Strong, fast air-cleaning performance (26 min to clear room at top speed) with decent value when the ionizer runs at full speed; Very cheap and widely available OEM/generic replacement filters.
Flagged: Much more power-hungry than similarly performing purifiers (75.3W at Speed 3), raising long-term running cost; Design is dated versus modern units; performance-per-dollar drops sharply without the ionizer and at lower speeds.
Levoit Core 300S
Two whitelisted hands-on testers reviewed this exact model: TechRadar (2023) and Tom's Guide (2025). Both measured it as genuinely quiet (60dB max at high speed) and praised its compact, low-cost, easy-to-set-up design. Both flagged sluggish, sometimes absent sensor response to sudden air-quality changes, making it better for steady background use than reactive cleanup. (2 sourced reviews, 2 lab-tested.)
Praised: Quiet operation overall; both measured 60dB max at high speed; Compact, lightweight, unobtrusive design that sets up in about 5 minutes; Strong value and smart features for a budget/mid-range price.
Flagged: Slow or missing sensor response to sudden air-quality changes; No replacement filters included; filters must be bought separately; App is basic and adds little beyond the on-unit controls.
