I mostly use mine just for monitoring humidity (I use a humidifier, but don’t want the humidity going up past 60% or bad things can start to grow) and CO2 which I try to keep below 800-ish PPM by keeping the window slightly open (except during pollen season, which is now)
There was an initial effort of doing things and seeing the effects and eventually finding a nice equilibrium. I now have a feel for what’s needed and it’s not something I put any thought into. I basically check it when the seasons change. Rather than contributing to anxiety, I am now relieved of unknowns.
I’m quite allergic to pollen, and very sensitive to things like smoke, so I’ve already someone more focused on managing my environment than a normal person. A wick based humidifier (don’t use ultrasonic, those breed bacteria and launch them into the air) and large air filter with a big but quiet fan are the most important things in my room. Yes, even the bed.
These devices can also be a good way to catch localized air pollution that exceeds safety limits, though where I live that’s not an issue. Citizens capable of checking air and water quality is a positive in my opinion.
>I use a humidifier, but don’t want the humidity going up past 60%
out of curiosity, what part of the globe do you live (or when was your home built) that you need a humidifier? I have a dehumidifier as it is quite often > 50% humidity in my home, easily as much as 65%, but that's due to the high humidity outside where it can easily be 85%. Just looked at my sensor, it is currently 81% outside and 55% inside. That 55% is where it really starts to become uncomfortable. I struggle to keep it <50% inside. At these indoor humidity levels, it limits some of the things that I can do indoors as it has a negative affect on things I make/do. So adding humidity is just one of those things that makes me tilt my head sideways and go huh? like a dog because it is so out of my experience.
The Pacific Northwest, where today’s humidity is 70%.
However that’s basically irrelevant because the place I rent has a 20+ year old central heating and cooling system, so inside the humidity can drop below 40% and I’ll get painfully dry sinuses and nose bleeds.
55-60% is my own comfort zone
In cold climates the humidity can drop to uncomfortable levels during the winter (sub 30% where I live). Especially when combined with wood fired stoves.
