Our take
If you have an open living area where pets roam freely and budget isn't the constraint, the Blue Pure 211i Max is the most powerful option that won't spike your electricity bill.
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.
