What’s the Smart Air DIY 1.1 Air Purifier?

We’ve made a simple improvement to the design of the DIY, and it simply works better! We’re calling it the DIY 1.1. It makes the DIY easier, safer, and stronger. Here’s how.

More Effective

We added a side-guard, which focuses more air through the HEPA and creates a higher pressure differential. What does that mean? It means more clean air!

We tested the new design in a 15m2 Beijing apartment and found the DIY 1.1 removed 8% more 0.5-micron particles and 3% more 2.5 micron particles.

We also had a third-party testing lab run CADR tests. In these shorter tests (20 minutes), the difference was even larger—a 15% improvement!

The new side guard also helps keep the strap in place. You’re so awesome, you probably didn’t need it anyway, but for dummies like us, it saves us some time fumbling around fitting the strap-on, and avoids the HEPA being knocked off!

We added a safety mesh to the front. That helps protects sneaky fingers and paws from touching the fan blades.
