That's really interesting! I switched from electric to gas (I regret not doing induction) and I found the pm10 and 2.5 are very similar for both. It is Co2 and No2 and vocs that surprise me about the gas stove. I'm no expert, just a lay person trying to make sense of it all but maybe the PM is from the food and therefore pretty consistent for all types of cooking?

Convection just means "An oven with an internal fan to circulate hot air" (so actually not convection in the sense of a temperature difference driven air current).

>did you mean induction

I did! Thank you, don't know how convection ovens got in my head.

> gas emits many times the amount of PM2.5 as electric

You are right. Gas stoves are worse on all air quality metrics, and the actual food cooking is only a tiny source of PM.

In your experience is cooking on induction still the #1 poor air quality cause in your house?

Off topic: how do you measure pm2.5 and pm10?

I have three air monitors I got used. It's a really niche market so I get them cheap. I have a uhoo, laseregg, and airthings. None of them are super accurate and I bet I am measure a lot more than I want but I can see trends enough to make some good guesses.

Last time I spoke with a doctor about sinus issues they just told me to grab some OTC remedy and that was mostly it

The more doctors I see, the more I just feel like a ticket in a queue that needs to be closed out and billed ASAP.

Thank you for saying that, I thought maybe I was just bad at choosing doctors.

The contrast indicates that regularly replacing the HEPA filters of APs could represent an effective method of avoiding increased endotoxins in the filtered air. That's a pretty clickbaity paper title. The lede was buried. A better title would have been: Regularly replacing HEPA filters may reduce endotoxins in filtered air I'm a high school drop out so what do I know.

"Dirty filters can release bacteria poop" wouldn't get as much interest.

"Your house is full of invisible poop" would definitely get my attention

Life is better if you can dust and vacuum on days when you can open the windows. I don't think people understand how much dust the vacuum cleaner doesn't pick up, not because it goes through the filter, but because it gets kicked up by the brush and never enters the fan at all. If you don't believe me, try vacuuming a particularly dirty carpet while barefoot. Exchanging the air before the dust settles out is a lot be…

What's the evidence that bacteria smeared around on an otherwise visibly "clean" kitchen counter, or dust kicked up from your carpet (which is largely human skin cells anyway) is actually harmful or "unsafe"? A relative of mine is a 70 year old widower. He's a huge slob and after his wife died 10 years ago, he really doesn't bother to ever clean his house or his kitchen. It's not depression, he's just never been a pa…

Sorry, that's my fault. I said 'bacteria' but the studies were on food-borne pathogens on surfaces. So spreading, for instance, a little e-coli from the pork chop you cooked properly, killing everything, to the asparagus you steamed by touching the same surfaces after 'cleaning' them and not accomplishing your goal.

The older I get, the more doctors I see, the less each doctor individually does, the more evident that the rapacious copay of my job-provided health insurance will drive me to less health care, perhaps obviating the need for any health care at all, though my executor will be left holding the bag of paying off outstanding bills.

I have been monitoring my indoor house air for two years now, and attempting to keep my air as healthy as possible. I have found that: 1) If you are lucky enough to live in an area with clean air, opening a window is orders of magnitude quicker and more effective way to clean air. 2) Gas stoves are the worst thing you can do to your house air (a fume Hood can partially mitigate this) 3) You should be weary of using a…

Can you give some reqs on what your monitoring system looks like?

I've been wanting to monitor our house's air quality for a while, but usually get put off looking at how poorly most affordable air quality monitors are reviewed.

Also, what metrics are most important? There's monitoring out there for pm2.5, pm10, HCHO, CO2, AQI, TVOC, etc, it's a bit of an alphabet soup.

Iq air or purple has some nice stuff

Yes, but there isn't much competition anymore now that I've removed all combustion appliances, so only in the comparative sense. Nowadays the biggest air quality issues come from outdoors (pollen, smoke, NOx from nearby freeway).

I’ve read that the rubbing alcohol is preferable to vinegar for disinfecting because vinegar can damage countertops.
