On another page on this website, it says that the DIY 1.1 was tested in a room size of 15 sqm with 92-95.5% effectiveness. The description for the Cannon says “From our testing, we’ve seen that the Cannon is 96 – 97% effective against PM2.5 in a room size of 15sqm. So the Cannon works in a room about twice as large as the Original DIY.” So does this mean, that with the new improvements, now the DIY 1.1 can be used in a room of 15 sqm just like the Cannon? Can the DIY 1.1 be used for a… Read more »
