         | Search the HN archive. There are lots of debates and
         | discussions about air quality sensors, especially around the
         | time of the West Coast US fires.
         | 
         | But from right now, every time you turn on your gas stove or
         | oven, open a window and set your stove extractor fan to
         | maximum, even if it briefly makes your house cold.

           | general though folks here discussed AirGradient kits.
           | https://www.airgradient.com/open-airgradient/kits/ I bought a
           | stack of them, and I recommend them. The Pro kit at least has
           | extra I2C module spots on the board (one for 3V3 modules, one
           | for 5V modules). They sell a SGP41 module for VOC, and (I
           | didn't know this until I looked at the spec sheet [1] just
           | now) it also supports NO2. The output's apparently an "index"
           | rather than calibrated physical units that you could compare
           | to the threshold/graph in the post though.
           | 
           | (btw: iiuc the "special" thing about the SGP41 module sold by
           | AirGradient as opposed to some Alibaba vendor is that the
           | AirGradient one doesn't come with surface-mounted terminating
           | resistors installed. If you buy one from somewhere else and
           | want to plug it into the AirGradient board, you need to
           | desolder those because the AirGradient's I2C bus is already
           | terminated elsewhere.)
           | 
           | I have an older SGP30. Less luck there; it does VOC and CO2,
           | no NO2.

         | There is no such thing as a clean burning gas stove. Even when
         | not in use, they leak methane, and the majority of methane they
         | leak is when they are not in use.
         | 
         | All gas stoves and ovens, regardless of cost or age, put levels
         | of pollutants into indoor air that are greater than what is
         | safe [1]. A $15k Wolf range is no better than a $1500 range.
         | 
         | The solutions are to either introduce a lot of ventilation, or
         | switch to non combustion cooking.

       | be part of the solution, so here are few things that alternatives
       | need to figure out before I move off gas:
       | 
       |  _Easy problems_ :
       | 
       | 1. No more cycling-induction/electric stoves. I do not want my
       | food alternating between burning & sitting around.
       | 
       | 2. A power setting where low-to-medium aren't only kind of
       | burning your food.
       | 
       | 3. Off means off. I don't want my food cooking for 5 more minutes
       | after I turn the stove off.
       | 
       | 4. Kitchen ranges having high quality broilers to make up for the
       | lack of a charring mechanism on alternative ranges.
       | 
       |  _Hard problems_ :
       | 
       | 1. Being able to change the shape of the surface element to trace
       | the shape of the pan. I cook with a wok, and all non-gas-ranges
       | only heat the very center. If I can use a wok to fix the shape of
       | the coil into a bowl, then I can ensure even heating even in a
       | wok. (It's a spring coil, the shape should be mechanically
       | adjustable).
       | 
       | 2. Can the good ones be competitive on prices with top gas ranges
       | ?
       | 
       | I really dislike electric stoves, they have the worst of all
       | worlds. Induction stoves: I could live with, but the good ones
       | are too expensive to be a reasonable alternative for most people.
       | There are additional good reasons to switch as seen from this[1]

       | Final caveat for tropical countries. Here, windows are always
       | open. Houses often lack a gas connection, and instead have a gas-
       | cylinder supplied to the house. So the pollution & removal-of-gas
       | benefits do not apply. The cooking culture often relies on
       | instantaneous fire to give certain staple flavors. They rely on
       | curved pot shapes for cooking techniques & and the price
       | differentials hurt a lot more when you're a poor country.

       | If anyone is curious I have a Qingping Air Monitor Lite which I
       | love. It's probably sucking up my data but I don't mind too much
       | because it has a great physical interface, natively connects to
       | HomeKit so I can see the current status and trigger events when
       | levels get too high, and has a decent app that shows charts over
       | time.
       | 
       | It's nice to be able to remotely see that particulate levels are
       | rising and turn on my air filter for a bit so everything's back
       | to normal by the time I get home.

       | New building codes call for mechanical ventilation, but not
       | nearly enough to compensate for the byproducts of combustion

       | 
       | The best solution (an airtight house with 24/7 whole house

         | I have a new house (built in 2020) and it did come with an
         | inefficient, underpowered mechanical ventilation intake that
         | just pulled outside air directly into the home. Given the house
         | is in Austin, Texas where the weather outside rarely matches
         | the conditions inside, this results in a lot of cooling or
         | heating loss, as well as losing the humidity conditioning of
         | the indoor air. It's no wonder that I regularly hear locals
         | advising folks to simply turn off the mechanical ventilator;
         | bringing in hot, humid summer air or cold, dry winter air is
         | not good, even if the fresh air is.
         | 
         | That's why shortly after moving in, I had the garbage
         | ventilator replaced with an ERV. Based on my research I
         | selected a Renewaire EV-Premium L, a variable speed unit which
         | does up to 280 CFM. That's a ton of fresh air, even for a 4300
         | sqft house. But importantly it preserves some of the
         | temperature and humidity when exchanging the air, so it's a lot
         | more efficient than a plain mechanical ventilator.
         | 
         | I have it wired into my Ecobee thermostat. It runs at its
         | configurable low speed 24/7, and the Ecobee puts it in boost
         | mode (full output) for 10-15 minutes per hour.
         | 
         | This setup did cost some money of course, but the $2000 cost
         | was pretty minor in the context of a new home. With this setup,
         | we never see a buildup of CO2, VOCs, etc indoors. Definitely
         | worth it when we're both working from home and spending most of
         | our time there. And although we have a gas cooktop, I never see
         | any indoor air quality issues so long as we're running the hood
         | while cooking.
         | 
         | I hope indoor air quality becomes a bigger priority for homes,
         | offices, and schools. The building codes in this area haven't
         | yet caught up to the need for improved ventilation to account
         | for how much better sealed up modern buildings are.
