Is the air coming out of the Smart Air DIY air purifier clean?

This is the easiest question to answer, and we do it by holding a Dylos DC1100 Pro particle counter in front of the purifier and watching the numbers drop. Here’s a video of Smart Air Founder Thomas doing just that:

Conclusion: Yes, air coming out of the Smart Air DIY Air Purifier is clean.

Is the Smart Air DIY air purifier able to actually clean the air in the entire room?

Answering this question is more difficult because you need a controlled environment (for example, you don’t want to walk in and out of the room during the test), and you need to test the air for a longer period of time. But fortunately for you, Thomas is a huge nerd and does this kind of thing for fun.

To answer this, Thomas set up the particle counter on one side of his 13.5 m2 bedroom and put the DIY filter on the opposite side of the room. Here’s what our filter did in one hour:

And over the course of eight hours:

The particle counter also gives data on .5 micron particles — even smaller than the 2.5 micron reading. Here’s what that looks like over eight hours:

Conclusion: Yes, the clean air from the DIY filter is cleaning the entire room.
