5 guides in Home & living
The Core 300-P moves 143-167 CFM through a $29.99 filter in a 7.9-pound cylinder sized for 222 square feet — the bedroom-budget answer, with anything bigger left to the $200 class.
A $329.99 monitor that measures radon plus six other things, reaches its rated 5% radon accuracy only after two months, and cannot replace a certified radon test.
Frigidaire's 50-pint nameplate reads 49.71 pints a day under DOE's colder 2019 test, and ENERGY STAR counts 521 kWh a year. The real decision is drainage: a 21.6-pint bucket hauled by hand or a gravity hose — no pump.
Levoit lists the Classic 300S at $71.99: a 6 L top-fill tank, up to 60 hours on low mist, and auto shut-off when the tank runs dry. The recurring cost is labor, not filters — a weekly clean with a vinegar soak — and every mist level runs from the buttons without the app.
Coway's $239.99 Airmega Mighty lists CADR of 233 to 246 and a coverage table whose 1,748 ft² headline assumes one air change per hour. The row that matches steady single-room cleaning is 361 ft², and the replacement filter set costs $64.99.
