I have a random question for those who survived the smoke in 2020 california: California homes have horrible insulation.. did having an air filter indoors make a difference?

#272EVs reduce tailpipe exhaust near roads but it's worth noting that brake abrasion dust isn't going away anytime soon and it's considered very bad to breathe, possibly in the same league as diesel emission particles.[1] I guess regenerative braking on an EV reduces this somewhat. Tire dust is also concerning.[2] [1] https://academic.oup.com/metallomics/article/12/3/371/595624... [2] https://pubmed.ncbi.nlm.nih.gov/2264…
Actually EVs are much worse than ICEs for tire dust and road abrasion, as they tend to be much heavier than an equivalent ICE car, with much more torque.

I'm no way an expert on the matter but by pure logic it's still amazes me how we survived (and evolved!) as a species for thousand of years without almost no shelter from direct sunlight and yet now (too much) sunlight exposure is seen as a cause of death. I know we lost almost all the body hair we used to have but still, we usually wear clothes when under the sun.
comparing average lifespan of 30 to 80?
That's actually a valid point, thanks. Although I don't know what's the age distribution for skin cancers.

> I have discovered that when I make this case, even to highly intelligent and health-conscious men and women, a psychological truth quickly becomes as visible as a pair of clenched fists: They do not want to believe any of it. LOL this happens whenever I talk about this issue with people here in Poland. Part of it is their family is here, it's hard to immigrate, deep down they know it is a problem. It was upsetting…
I think some people are so afraid of dangers to their health that they are even afraid to acknowledge them. I think I've seen a lot of this during the pandemic. When you try make people acknowledge the dangers they are facing they are going to panick and defend their peace of mind furiously. Anyways, good luck in the US. Avoid getting shot, having a pool, drinking sugared water instead of water, any medical issue and…
You realize your risk of death of air pollution in polish cities is 160/10,000 people? In the US the risk is 5 in 100,000 people.
sugar water will be a problem, I did not like this about the USA.
medical issue - with FAANG you're fine
bad side of the law: in the communities we live in faang, again, not a problem, you're on the right side of the law. Unless you're black, then that is quite a problem unfortunately.

Extinguish candles with a lid. If you are worrying about the method by which you extinguish a candle, worrying is what's going to shorten your life, not the candle.
I have a cheap pm10 meter and ran it continuously for a few weeks. Next too cooking meat the other activity that stood out was blowing out the birthday candles. The pm10 rose to 300 and only was backs to healthy levels (below 50) several hours later. I was as surprised as you are. Next time I'll definitely open a window
Not all particles are equally toxic. If I had to guess, the smoke from a recently-extinguished candle is probably condensed wax vapor rather than PAHs and heavy metals.

The question is how much CO2 can I fix with a reasonably sized apparatus and really I would prefer a continuous system (which is why electrolysis) rather than a batch system. Also I would prefer levels lower than outside, obviously air exchangers will necessarily be worse than just being outside.
You might try using oxygen conentrator with high throughput to concentrate oxygen from outside and pump it into your home. With small device I could drop CO2 levels to zero in volume of a gargabe bag in few minutes. But that would give you oxygen rich atmosphere. You'd probably want to add some inert gas to that. Nitrogen preferably. Are there nitrogen concentrators? Also all of that is probably really dangerous beca…
We are still talking about home... on planet Earth, right?

My first thought on the candles was: If you're worried about paritculate emissions and air quality in your flat then maybe just don't burn anything in your flat. I haven't researched that, but it always seemed entirely obvious to me that candles aren't exactly healthy in terms of air quality.
One big thing is natural gas combustion producing nitrogen oxides. Gas burners used for cooking make a LOT of it, right inside the home.

Depends on how much your drive. Drive only now and then and brake only the bare minimum, you can get really rusty brakes. I ended up having to get towed with brakes being seized due to rust and lack of use.
I didn't notice any more rusting with a hybrid with regerative breaking than I did with normal car. Rusting is for me more associated with the weather and lack of use of the whole car than with how much do you use breaks when you use the car.
Well yes, weather will cause rust. Good use of brakes can clean it up and keep the mechanism from seizing. Lack of braking = lack of use as far as the brakes are concerned.
I could run my errands without braking at all (except when stopping at a parking lot). Anticipate lights and traffic flow, downshift to slow down.. that's how I used to drive. At home I could even park without braking to slow down, thanks to a small incline at my parking spot.
My previous car, which had automatic transmission, didn't have really show any issues with rust because I actually had to brake when driving around town. Same weather, same locale.

Very interesting to me that gas is considered the 'high end'-option, I presume in the U.S? Where I live, the high end-option is to get an induction stove. I have one, and it's extremely pleasant to cook on. Granted, I've never cooked on gas because that alternative is mostly not used, in my experience.
Depends on what you’re cooking, but there are many types of cuisine that simply need gas burners to be properly cooked.
When I need flame to cook, a $20 butane canister stove works surprisingly well
