After some finagling to get the assembly procedure just right we are finally releasing the aluminum bodied POLARIS air purifier, made-in-Canada and based on the open-source design by Zack Deis. 1/3 #airpurifier #indoorairquality #covidisairborne

After a few different prototypes, the Guardian, our most affordable air purifier, is finally ready. #IndoorAirQuality #CovidIsAirborne #AirPurifier 1/2

Our MINI-SC is entirely built by hand and takes quite a while to make but it's just so much fun to put together! #airpurifier #indoorairquality #covidisairborne

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! #indoorairquality #covidisnotover

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 archive.md/Jyi7k

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!

Whole bunch of different stuff on the bench today, including some prototypes we are working on! #IndoorAirQuality #COVIDisAirborne #airpurifier

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. 1/2

I really should get the bench better organized!

Always encouraging to hear great feedback from people using our stuff!

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.

The truth about Sweden, Covid is a portal, Lower life expectancy baseline, and more johndupuis.substack.com/p/we-havent-...

This is an important potential treatment for Long Covid:

Our first shipment of fans has finally made it in! Over the next several days we will be getting as many of our air purifier kits and units out to everyone who placed an order...thanks for your patience! #IndoorAirQuality #CovidIsNotOver #AirPurifier

Here's a video outlining the assembly procedure for the Guardian portable air purifier kit: youtu.be/OpsFtNsCGp0?...

Here is a very small, quiet and easy to assemble air purifier that can be given to cancer patients upon entering hospital for treatment while their immune system will be suppressed. I'm hoping a charity might be interested in distributing it. It's called the Guardian: youtu.be/OpsFtNsCGp0 1/2

Some elements of our supply chain rely on US warehouses and all the tariff uncertainty led to a month long delay for the PC fans we use. Thankfully we are expecting a big shipment this week. We have prepared a lot of panels so we will be ready to ship asap!

Air Quality in Toronto not so great today. If you need to be outside, quality respirators are available at donatemask.ca at no cost if you can't afford them. #CleanAir #WildfireSmoke #MaskUp

We've just posted the updated kit assembly video for our North Box MINI-SC portable air purifier, now with electronic speed control! youtu.be/FvwPNqbxTV8?...

Amazing deal on Ikea's cute little air quality monitor, not big on detailed analysis but does a good job at giving you a general sense of your IAQ, only $5.99! www.ikea.com/ca/en/p/vind...

On #CleanAirDay, it's crucial to share how important it is to also think about air quality indoors. Using a HEPA air purifier, North Box PC-fan air purifier, or CR box can help! 🏠💨 #CleanAir #AirQuality

Air quality very poor in Toronto today, an N95 mask outdoors and air purifiers indoors would be a good idea. #wildfires #airquality

Vaccines are one of the most important tools we have to control the spread of Covid: youtu.be/oZBeepHwTtQ?... #Covidisnotover

First batch of a total of six 6XL air purifiers on their way to BC to help treat the air for firefighting crews who will be spending time in mobile facilities close to the wildfires. #wildfire #indoorairquality

Though our air purifiers can help keep your indoor air safe during wildfire season, filters should be changed after a major smoke event as their electrostatic properties can be compromised. #wildfiresmoke #wildfires #cleantheair #COVIDisAirborne

Buying one of our kits through Donate A Mask helps provide high quality N95 respirators to those who can't afford them!

Heart breaking story and a wake up call for those who think Covid is "just a cold": youtu.be/vqeIeIcDHD0?... #CovidIsAirborne #CleanAir #CovidisnotOver

DYK how many masks has Donate A Mask shipped through our Free Request Program? 😷 Any guesses? The answer's in the comments--but while we have your attention, make a donation to help us keep up this work! 🙏🏻 donatemask.ca/fundraiser #YallMasking #CommunityHealth #Mask #MaskUp

Our air purifiers can help mitigate the risk of wildfire smoke particles. It's a good idea to have plenty of extra filters as a serious wildfire event can adversely affect their electrostatic properties. #WildfireSmoke #CleanTheAir #IndoorAirQuality

Picking a wellness influencer as Surgeon General of the United States speaks to the deep connections between "natural health" and the extreme right. The conspirituality hustle will have serious impacts on public health. My latest. charlieangus.substack.com/p/maga-measl...

"For me, the answer now lies in refusal, the withdrawal of participation from systems that require dishonesty as the price of belonging." Today I am resigning from the National Science Board and the Library of Congress Scholars Council. I wrote about my decision in TIME. time.com/7285045/resi...

The MINI, our portable air purifier, is now the MINI-SC with built-in speed control. Throttle between an insane 5000 rpm to whisper quiet operation. Great when you need to clear a hotel room fast and then settle in for the night! youtu.be/yM8Je_6yw_E?... #IndoorAirQuality

Meanwhile, this study emphasises the vital role of strategic air purifiers in reducing airborne infection risks & enhancing patient safety in healthcare environments: 'Their optimal placement in hospital wards can significantly improve air quality.' www.journalofhospitalinfection.com/article/S019...

Speed control tests for our POLARIS air purifier, a metal version of our 6XL but with more powerful fans that can be controlled for quiet operation when needed. youtu.be/XUh_YNT0pUk #CleanAirForKids #COVIDisAirborne

Working on an update to our MINI portable air purifier which uses the very powerful but loud Arctic P8 Max fans. Instead of purchasing a variable external power supply we are going to install a built in speed controller. youtu.be/rnBHnVbQDJk #AirQuality #CovidIsAirborne

I'm hoping this will be the year we can get some of our silent air purifiers into Canadian classrooms!

More confirmation that air purifiers are effective at removing airborne virus particles. A PC-fan based air purifier will give you excellent performance without the noise of a HEPA cleaner: www.sciencedirect.com/science/arti...

The good ol' CR Box still kicking ass!

Check out the House Fresh review of our 6XL PC-fan based air purifier! housefresh.com/northbox-6xl...

We've managed to bypass Amazon by ordering our electrical components directly from China. It's slowing us down quite a bit but we should have a big delivery of parts coming in the next few weeks. We are still recommending 3M Filtrete 1900/2200 for 1" MERV13 filters. northboxsystems.ca

A little tape can do a lot to spice up your air purifier. I call this FACT001 Hacienda Edition in honour of the legendary Manchester club where New Order and The Birthday Party performed in the early 80's. #IndoorAirQuality #NewOrder #FactoryRecords

With the Tariff threat between Canada and the US poised to cause increases in shipping costs and general supply chain issues we encourage our American customers to shop locally and support the fine folks at Clean Air Kits. @cleanairkits.bsky.social www.cleanairkits.com

I can't find this post on BluSky so sharing link to that other site: #N95 respirator masks are available for free to some groups and organizations through GCDonate. Check your eligibility: ow.ly/3oqF50V0krz

Buying our kits through Donate A Mask Canada helps provide quality respirators to those who can't afford them!

Thanks to everyone that contributed to this project. We almost hit 10% of our funding target and there's a lot we can do towards our ultimate goal of a mass produced PC-fan based air purifier. Our next steps: 1/5

Final 10 hours! Can we make it to 10%? Thanks to everyone who supported our goal to design a silent, powerful and easy to maintain air purifier that can be deployed in classrooms or any place air is shared. igg.me/at/n8zLwkwyT... #COVIDisAirborne
