Looking to build out the directory of clean air businesses at http://cleanairstars.com. These are businesses that have either assessed adequacy of ventilation with engineering assessments or ongoing CO2 monitoring, or have installed mitigations like portable air filters or UVGI. Canada has a few (https://cleanairstars.com/directory) but we need more. Anyone can add one at the following link cleanairstars.com/add. #cleanairstars #canadacovid
An option for Australian #corsirosenthalbox is this one below. 4x 3M filtrete 1900 20 X 20 x1 ($150) and a Dimplex 50cm DCBOX50MBK ($90) plus tape for a total of $250. At low speed (48dBA) it’s CADR Smoke ~600-850m3/hr.
$0.20-30 per CADR vs closest commercial competitor at $0.90 at <50dBA.
3-6mthly filter replacement costs if used daily may eat into upfront cost savings however (Starkvind HEPA filters for equivalent total CADR = 3x$20)

So @dfisman, now that I’m here, what’s a good way to find interesting accounts to follow?
