I recently bought a PMSA003 sensor and started logging the results indoors in a capital city. Three big discoveries were that opening the windows made the air quality way worse, sometimes the air quality is bad indoors and out without any clear coloration with other weather events and finally deodorant is absolutely awful.
We're about to start messing around with filters, I built a home brew one with a duct fan and an inline activated carbon filter, but we've bought a retail filter that will be here soon so that will be interesting.
I do think more people should be aware of their air quality.
- jackvalentine 4y agoI bought an air purifier a few years ago and if you use spray type deodorant in the same room as it the thing kicks in to hyper mode for a while. We’ve taken to saying ‘you made it angry’. Even farting directly in to it doesn’t make it do that.
- nannal 4y agoYeah, either I move to roll on or the world learns to live with my musk.
- graeme 4y agoYeah if you live in a place with pollution outdoors and no indoor HVAC there is a real severe trade off between co2 and aqi If a place is sub say 70-100 in AQI then usually indoors will be 4-13 AQI with windows open but above that you’ll see indoor increases with open windows.
- dzhiurgis 4y agoCold climates also suck for co2. There are very cheap hrv’s but I think they are noisy.
- graeme 4y agoThat one’s actually easier. Air circulates much better when there is a temperature difference. A single window opened a crack will generally ventilate most homes or apartments. There will be somewhat higher heating costs but usually not excessive. Less than a lot of non-essential things people already spend money on
- graeme 4y agoTo manage high AQI and high CO2 and you need the windows open enough to ventilate and enough hepa to lower the AQI pollutants that comes in
