What’s the Smart Air DIY 1.1?
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!
Easier
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!

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

Nice service, good product at this price. In just 3 days my filter looks black as it’s hazardous AQI. Seems to be workingv great.

Great product. Exactly as advertised. Highly recommended! Keeps the air clean at a super low cost without taking up much space or waking me up while I sleep. Perfect if you have a small apartment or a bedroom.

Great to see a company who really care and deliver a product that beats the 9k peso air filters for only 2.4k. I would have preferred the diy 1.0 since the metal guard is not needed and also the rear shrouding makes this utterly hopeless as a regular fan for emergencies (the air goes out instead of forward). I removed the metal guard easily.
My filter is getting blacker so it must be working. Like all air filters, the effective speeds are too noisy so i use this on level 1. Happy that the filter will last months. Low cost.
