A peek inside our 6XL, the adjustable tension cord makes for a tape-free design! We normally use 20x20x1 filters, but 2' filters will also work with this! This is a one-off in glossy black acrylic, if there is enough interest I'll make more. #CovidIsAirborne #WildfireSmoke

Get ready!

when a #CleanAir revolution begins, everyone will get on board, including municipalities . Kudos to City of Kelowna !

The first production NorthBox 6XL is finally ready after many last minute design changes and back ordered parts. CADR 290cfm! Huge thank you to everyone who preordered, my son and I will try and get these out ASAP! #IAQ #CovidIsAirborne #WildfireSmoke

Wow, great to see some victories happening around providing kids in school with safe air to breathe! Come on Ontario!

This is a great initiative. Not only do these boxes provide clean air against wildfire smoke, they also protect people against airborne viruses, like COVID19, flu, RSV, Measles, etc. BC Lung Foundation Could you please get this campaign going in every school district? #CleanAirMatters

Thanks to some great advice I now have a very sturdy 9-fan array for my 9-for-4 prototype!

During wildfire season I'd recommend setting your car's climate controls to 'recirculate' as the smoke particles will clog up your car's HEPA filter pretty quickly. Keep one of our MINIs in your car to scrub out whatever particles get inside!

Another North Box 5X chugging away, keeping the air clean!

This enrages me to no end, they don’t care as long as they’re safe.

In the company of some fine people!

These look fantastic, definitely going to try them out!

Finished the first prototype of the '9for4', I didn't have any 2' filters to test fit it but used what I had on hand to ensure all the cables were nice and neat. It uses nine Arctic P14s.

Working on this one-off 9 x 140mm fan monster that will use four 20x20x2' filters. Maybe something I'll make available if it works as well as I'm hoping.
