Somewhat tangential: I met the founder of this https://www.atalantaclimate.co/ at new york climate week yesterday, it does all the regular air purification stuff, but it also removes carbon from the air, they claim this helps with sleep and work focus in your space (not sure), their demo was impressive (off the shelf co2 monitor in 2 spaces) - I wonder if this is going to be a thing?
Starting at around thousand bucks, with a subscription for their pods, requiring constant maintenance, with a huge footprint - I'd say this is targeted for someone with more money than sense. There aren't any clear numbers of what this device can do. The negative effects of CO2 are also quite overstated, and I say this as someone with two CO2 monitors in their home.
Yeah, for sure not cheap - founder was saying they think they can get them down to $300 and half the size, they're a Canadian team so they did the first batch in Canada, I guess they plan to move manufacturing to China. I was more wondering if this is a feature we can expect to see more generally, seems like an interesting idea anyways. :)
I sleep in what would be considered a relatively large master bedroom with ensuite. Recently got an AirGradient One sensor and was shocked at the overnight co2 levels.
When sleeping with window and door closed and just by myself, co2 levels exceeded 2,000ppm by morning and only fell once I was awake and opening doors.
With the window slightly open and the door slightly open, levels were at a much better 700ppm or so.
If this thing works as advertised, that would be great. There are a lot of situations where it’s difficult to sleep with the window or the door open.
I configured my furnace to always recirculate air in the house even when burner itself is off - helps to avoid rooms with stale air and evens temperature through the house.
Your HVAC is supposed to recirculate the air using the fan feature. And you don't even need to run it 24/7; I find that running it for a few minutes each hour is enough to get CO2 levels down.
