A look inside the Polaris ULTRA, this version comes with a PWM control board so you can use multi-speed fans. Pre-built systems and Deluxe kits come with Arctic's new P14 Pro fans but experimenters can use any 12volt PWM fans.

Checking out some nifty digital timers to add automation control to an air purifier. Up to 15Amps so you can have multiple units controlled. Great for classrooms where you can just hit the 8-hour button and you are good!

COVID Isn’t a Cold. It’s Cigarettes All Over Again.
5 years into this experiment: we let COVID rip and pretended it was fine. Damage piled up—unlike smoking’s slow toll, we’re seeing it in real time. Every infection leaves a mark; even “mild.” The bill comes due. We chose denial

We'd only been in BC a month or so when a wildfire rained ash on our car and smogged up our apartment. Worked with the folks @northboxsystems.bsky.social (thanks to a rec from @cleanairkits.bsky.social) and got a custom air purifier together with adjustable speed fans. No more proprietary filters!

Realizing the original 8 x 80mm fan was misguided, here is the redesigned Guardian. My goal was to make the cheapest, quietest and most portable solution. Aiming for chemo patients going into hospital, it can be a great solution for any smaller space.

Always encouraging to hear great feedback from people using our stuff!
Feeling especially grateful that I am able-bodied enough to work full-time to afford this.
A huge improvement over my CR box! So quiet! 😀
This was ordered through NorthBox systems and I just installed the filters today.

I should have grabbed a photo but wanted to be sure to post a quick "Thank you!" to @northboxsystems.bsky.social and my pair of North Box 5X Classics for keeping my TAs safer during our training workshop yesterday.
These beasts are so quiet no one has ever noticed them until they actually see them.

This is an important potential treatment for Long Covid:
I still have not been able to find a GTA doctor willing to help Openwater with the 150 kHz ultrasound treatment of Long COVID microclots.
Openwater will provide all the materials. Literally just need a PHD candidate or doctor to administer.
Interested or know of anyone? Pls DM🙏

The more we can diagnose & treat Long COVID issues (like microclots), the better life will be for everyone.
