It's not always easy to explain how we simplified CPC's, but I think this image really makes the case on how we re-invisioned what the optical counter within the CPC could be.

OpenAeros @openaeros.bsky.social · 1d

Reducing complexity ➡️ reduced cost ➡️ reduced price.

Optical counters are the heart of high-performing CPCs. By using the latest in manufacturing technology and some ingenuity to simplify and modernize our optical counter, resulting in a 10x reduction in associated manufacturing costs.

A graphic features a flatlay comparison photo of machine component parts of various shapes and sizes on a cool grey woodgrain tabletop, a black line divides the graphic in half vertically: on the left, the title "Traditional" sits above the photo and the following specs are displated below the photo: "9 machined components, 4 lenses, 48 total components"; on the right, the title reads "openCPC" and below the specs read "1 machined component, 0 lenses, 17 components"

@mfrumholtz.bsky.social just listened to you on the Wedge Live podcast. There were a few misstatements about air pollution that I think are relevant to the discussion. If you would like to chat about them and connect just let me know.

The @saferairproject.bsky.social is hosting an amazing event on why IAQ matters, IAQ performance standards and policy discussions. If you are in AUS a must attend. Livestream option (hybrid) and recording afterwords.

Just registered myself, should be great!

This year, we’ve been working with a team of passionate, creative makers to put our open source respirator prototype manufacturing methods to the test. We’re so excited to be introducing you to a couple of them this week. In the meantime, here’s some background on what we’ve been up to: (1/4)

The momentum for clean indoor air continues to build. I attended the inaugural High-Level Side Event on indoor air quality at the UN General Assembly yesterday. Short remarks by Lidia Morawska @joeallenjoe.bsky.social @isiaq.bsky.social Pres. Kerry Kinney, ASHRAE, WHO, UNEP, many others.

Aaron (and our little CPC! 🥹) are taking their places on the floor of the UN! This year is the inaugural General Assembly High Level Side Event on Indoor Air Quality and we're so excited to participate.

The panel will open soon, watch along here: webtv.un.org/en/asset/k1v...

Glad to bring the "little CPC that could" to the Healthy Indoor Air event at the UN today. The conversation in clean air are moving in the right directions.

Open source hardware will be part of the solutions and proud to show off the OpenCPC as part of tools that can help us measure it.

An early AM flight to NYC to join the Healthy Indoor Air event at the UN tomorrow. This is an important step in the process of helping get clean air legislation. You can watch it live tomorrow between 3:30 - 5:30PM ET.

We are limited by budget, so these units will add about 1.5-2.5 eACH to the space, or effectively mitigate about 7 kids worth per classroom. It isn't perfect and with double the budget I think we could hit close to ASHREA 241 levels with current HVAC system.

Clean air is not complicated, and costs less than $10 per kid per year to do. This is the 4th year of managing this for my son's school. What happens when he moves to the next school, who will keep doing this for the other kids? We need clean air standards and legislation.

I couldn't think of a better way to have spent the last 2.5 years of my life. I am incredibly proud of what the team at @openaeros.bsky.social was able to accomplish. There were many who said this was impossible, but we did the impossible and this is just the start. 😁

We believe that clean air researchers and proponents are doing critical work for our health and future. Too few have had access to the tools to investigate the next frontier of airborne pollutants: ultrafine particles. But we have big news... (1/4)

Have not tested them, but in general in 2025 if it's not tested against a respirator standard (N95, FFP2, KN95) then likely device can't meet those performance specs. Their website doesn't list any mask standards it complies to but claims a general "95%" which to me is a red flag.
