Hey Achim and team,
It is really hard these days to find companies that are genuinely trying to do a great job and are trying to create the highest quality while balancing the challenges of business life. Integrity is key and is usually the first thing that goes out the window when corners need to be cut. I highly appreciate that you chose the high road ad you are committed to build quality and protect the integrity of both of your product and your team.
I have just run into AirGradient relative recently. Read 2 newsletters and have been to one of your webinars, but I have to say it really feels nice to run into some great company in the process of learning about safeguarding clean air and helping others understand why this topic is important.
Keep up the great work.
Also the blog posts. I have saved about 80% of the links I got from you so far, for further reference later or to be able to send to other people easy to consume resources on this highly complicated topic.
The work you are doing with schools, the UN, LA and all across the board is very inspiring.
This reply turned into a general acknowledgement. It had to be said.
However, I do feel the struggle of buying the right monitors and how to address sensor quality as an end user.
Not only buying but maintenance is also in question.
I have 2 PM2.5 sensors like the ones you use and just got an Atmo tube. I was considering buying all kits available on the market (there are a few these days) to see the distribution of data I get, but it feels like an uphill battle without lab level equipment to test them.
I would love to know if you have some recommendation on sensor maintenance or if you considered something along these lines for your product too.
Even if I buy the assembled kit from you, I am not sure how and when that should be looked at to make sure the readings stay accurate.
Would love to hear your thoughts on this.
Keep up the great work,
Timea
