One big air purifier vs two smaller ones, which cleans air faster? If the total CADR is the same, one big purifier and two smaller purifiers clean at about the same speed in a well-mixed single room—because clean-air delivery is essentially additive. The real reason to choose two units is better coverage and circulation in … Read more
Should you run an air purifier 24/7? For most homes, yes—running an air purifier 24/7 is worth it if it’s correctly sized for the room and you run it at a quiet “baseline” speed. Continuous operation keeps particles from building up again between sessions. The best approach is low/auto all day + short “boost” runs … Read more

But it’s not a universal “smell/VOC vacuum.” Carbon works best when you have enough carbon (not a thin sheet), enough contact time, and you’re targeting the right gases—and it always has finite capacity (it fills up). … Read more

Every one of those is fixable in under 15 minutes. This guide walks you through 7 … Read more
If you want an air purifier that actually feels effective, shop by CADR first. It’s the closest thing to a “speed rating” for how much clean air a purifier can deliver in a real room.
