It seems plausible that CADR is becoming just a bigger number without improving effectiveness, like megapixels.
It also seems plausible that Dyson is just struggling to avoid commoditization because it's a losing battle for them. And it's possible some of that has merit, because running a noisy fan when the air is already clean seems annoying.
- sdljfjafsd 6y agoCADR is an important metric for determining if a purifier is correct for your room. You can use it to calculate how many air changes it does per hour. If that number is too low, the air purifier is not going to work well in your room. Basically there's a minimum CADR for each room in your house, but of course, exceeding that gives you little benefit. Most people search for devices that are ~4 air changes per hour.
