Coway is the more straightforward candidate.
Shark's screen design deserves attention.
Compare actual carbon media and replacement cost.
Price genuine filters rather than relying on a headline interval.
Spend more when odor, hair, or monitoring is a repeated apartment problem that affects daily comfort.
Spend less when a manual routine, washable cover, or basic camera solves the same issue without subscriptions.

No. Litter, bedding, fabrics, and cleaning remain the primary source-control steps.
No. Screens, sensors, placement, and eventual filter replacement still require attention.
Compare room size, tolerated noise, light controls, and placement clearance rather than brand alone.
