www.communityairsensor.orgCommunity Air Sensor Workshop 2025The Community Air Sensor Workshop was created to continue the critical discussions and knowledge-sharing around emerging air sensor technology, especially in light of the cancellation of the U.S. EPA Sensor Workshop 2025. While that event will no longer take place, our virtual workshop provides a collaborative space for experts, organizations, and community members to exchange best practices, explore innovations, and advance air quality monitoring. Through interactive sessions, hands-on workshops, and open discussions, we aim to empower communities with accurate, accessible air quality data—driving innovation and informed decision-making for a cleaner, healthier future. This event is completely free and organized entirely by volunteers who are passionate about advancing air quality monitoring and making sensor technology more accessible. Our goal is to ensure that knowledge and collaboration remain open to all, without financial barriers. We appreciate the dedication of our organizers and contributors, whose efforts make this workshop possible.

Hi all, I've just setup my own #Akkoma instance, so it's time for an updated #introduction
I promise I won't move accounts again and I'll keep @kedara as a backup.
I'm very much into #yoga and #meditation and everything related to that. I'm trying to learn #Sanskrit because its a beautiful language and also in order to be able to read text like the #BhagavadGita #Upanishads #YogaSutras which greatly inspire me.
I'm from the #Netherlands and work in #science in the field of #AirQuality I may occasionally share something about that, but this is not a work account (and any opinions are my own).
I love #photography , mostly related to #nature #weather #clouds #trees
I try to make a trip to the #forest at least every weekend, I'm lucky to live at the edge of the #Veluwe nature area.
I love growing food in my #garden using #organic #permaculture and #RegenerativeAgriculture inspired methods, I'm dreaming of tending my own #FoodForest some day.
Unfortunately I'm operating at half power thanks to #LongCovid since Feb. '22.
I'll mainly post in English with some posts in Dutch as well. Unpinned toots will be deleted after 3 months, I only boost photos with alt text (feel free to let me know if I've forgotten to add it!).
Let me know if you have similar interests and I'll be happy to chat!

Air Quality Advisory
A fire has been reported at Martinez Refining Company. Air District inspectors are investigating. There is potential for smoke impacts in the immediate area and downwind neighborhoods. Avoid exposure if smoke is impacting your area by remaining indoors with windows and doors closed. Follow instructions from local health officials and check back for updates. See current air quality at fire.airnow.gov. #airquality #MartinezRefineryFire

AQI marginal this morning, worse earlier. Probably stuff smoldering in Santa Clarita due to the Hughes Fire. #aqi #airquality #smoke #HughesFire
If you use an air purifier that does not indicate when the filters need replacing, how do you (you specifically) tell when you need to replace them?
*I'm asking what you do, not for random men to yell at me. lol
I'd love to know how people handle this.
Although I suspect supplies will be hard to find, here's instructions on building a HEPA purifier (Corsi Rosenthal Box). A good chunk of Ventura County is unhealthy air tonight, and it would be useful to have one or two of these running to protect your lungs. #airquality #AQI #CorsiRosenthalBox

The device was created to provide significant reduction in the amount of virus-laden, aerosol particles that are in the air. Follow along as Dean Richard L. Corsi, co-inventor, shows you the major components of this device, and how to build one.
It's alive! I'll properly solder and box it up later this week #homeassistant #esphome #airquality #co2
Air quality in Ventura and LA County, except near Altadena, has improved significantly since this morning (per purpleair).

If you're also considering a filter, a CR box is a great DIY option that has been proven to be just has effective or better than some of the fancy $400 ones. https://cleanaircrew.org/ufaq/does-the-corsi-rosenthal-box-work/
For outdoors, there are a variety of open data maps you can use from local air quality monitors regarding fires and quality.

Always check local ordinances around whether you can start a fire before burning anything on your property or when camping and hiking. Some grounds may require that you keep a fire extinguisher on you. Make sure you are familiar with how to report a fire and have a plan to evacuate during no burn periods.

For folx considering air quality monitors following the LA fires. A few months ago I purchased an Air Gradient One for indoors due to fires near my hometown. You can use the code "SABP13ET" for 10% off (SmartHomeJunkie). It's open source, homekit compatible, and hackable, but also works well out of the box. You can view historical data from web view on your phone or laptop. Having a monitor allowed me to determine if an air filter was necessary from the fires and on the day to day reminds me to air out the room from CO2 build up or from running my stove, even when out of the house. The discounted DIY model was as easy to build as three pieces of legos and a few screws. https://www.airgradient.com/indoor/
Other monitors I considered from reviews on reddit where the HotKrem 5-in-1 and TemTop M2000c on the more affordable end. I also considered mainstream competitors like Air Things, Purple Air, and Govee. I decided that the price was not worth the performance, though there are plenty of people who are satisfied with their purchase.
