Our take
If your cat sleeps in your room and your allergies are suffering for it, the Core 300 is the no-brainer bedroom fix — quiet enough to sleep through and effective enough to actually make a difference.
Coway gets more hype, but if your dog or litter box is the main problem, Winix's carbon filtration and PlasmaWave tech make it the better odor fighter — and it's built to last.
