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.

Thanks for the suggestions. The interesting thing is that testing by Rob Wissman shows you can get away with having filters very close to a wall before you see a significant drop in performance. We don't use USB power, a 12v / 2amp supply is included.

It uses four Arctic P14 fans and two Ikea Starkvind filters. With an integrated handle, rubber feet and a wide footprint to prevent tipping.
Ideal for smaller spaces or for hospital stays. I'll have it up on our website soon.

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!

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!

Oh yes, we already have our MINI-SC which uses 4 x P8 Max fans and has PWM speed control. I'm working on something called the "Guardian" which I'm hoping will be the cheapest machine we will make, 4 x 140mm fans and 2 x Ikea Starkvind.
This is an early version with 120mm fans:

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.

We've got a little kit we're hoping can be given to patients before they go into hospital to help mitigate the risks from airborne viruses, I'm hoping a charity would be interested in working with us on this, particularly for cancer:

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:

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.

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.

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.

Not sure for that study, but we use MERV13 furnace filters. Instead of using a small dense HEPA filter and a very strong but loud fan we use a two very large, less dense filters and a bank of very quiet fans to achieve the same CADR.

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.
