Nice hack. But my xiaomi air purifier works just fine with a non-xiaomi filter - only thing it will do extra is show a warning at power on.
True for the older models but the new ones switch off after a certain time

Mine is a 3H.
Strange that some models are affected but others not.

I was so skeptical. Living in SF in 2018(?) during the wildfires, my apartment was drafty and I’d come home from work to a hazy indoor environment. I’d wake up with a sore throat and that’s what got me to take action (can’t sleep with an n95 on) I got the cheapest air purifier from Amazon and just put it on my bedside table. After one night my sore throat was gone. As simple as these machines are, they do work.
I can see how an air purifier makes sense in that 2018 scenario. I guessing that the benefits are less certain in more typical cases.
I've built dynomight's DIY filter[^1], and I love it. No DRM issues either. [^1]: https://dynomight.net/better-DIY-air-purifier.html
Can someone explain what's the result of filter utilization / capacity. Is it efficiency? Does it start spilling out particles? I feel like a 100% used filter will still do a pretty good job, so unclear how much of the utilization % has commercial reasoning?
I've never experienced an air purifier, what's the general consensus? Do they make a difference? Perhaps a placebo? A must have? Genuinely interested if I'm missing out - For what it's worth I do live right on a main road in the UK, so I expect there is some level of pollution in the air.
If you have central air heating/AC and a vacuum cleaner that has a hepa bag, you likely don't need one; just buy filters that aren't the blue spiderweb kind and vacuum regularly.

Ancedotally they work 100%. Not only do they remove noticeable odors, they suck up tons of allergenic dust and invisible particulates that can mess with your breathing (if you have a sensitive respiratory system). Non-anecdotally, I've heard it claimed that indoor air pollution is the #1 factor in reducing the lifespans of otherwise healthy people. No idea if this is the case or what the evidence is, but I don't find…
In developing countries they have poor stoves at home which give of smoke/CO which is harmful aka indoor air pollution. A good easy way to prevents deaths/harm from these is to provide them with quality stoves. So depending on where you heard it, air pollution could mean these stoves which typical don't exist in the developed world

Efficiency in terms of airflow goes down, and static pressure difference goes up - but the filters trap more of the particles going through them. Changing filters on furnaces and AC units is really important, since lack of airflow hurts efficiency. Wirecutter (which is usually trash) confirmed this in testing; versions of units that had been running for months or longer (ie one they bought a year ago and used in some…
curious - why is Wirecutter trash? I’ve been sorta feeling iffy about them for no real reasons but they seem highly recommended
In my case I bought a couple Coway air purifiers only to find that Coway doesn't honor their warranty. I hit all the common complaints from the comments section – comments Wirecutter staff refuse to acknowledge.

Oh ok, I heard some of them switch off for sure (after a few hours). I read this on an online forum discussing integration with Home Assistant, some users got around it by just setting an automation in Home Assistant to switch it back on again :) Which is what I would have done if my 3S had had the same problem. But it doesn't. Strange that some models are affected but others not.

They almost always conveniently only recommend products that allow for referral fees.
The product manufacturers don’t pay referral fees, it’s the retailer. So your entire argument against them is you’re mad they make money by linking to Amazon or target?
That's not my entire problem with them, but it's a problem. Because they're reliant on referral fees their motivation is purely to get you to buy random crap whether or not it's any good. So long as their reputation holds up that's good, but once they start promoting crap there's going to be a long tail of folks who think "oh it's on wirecutter, it must be good".
Take a look at their reviews. It's not that they promote stuff that they might get a kickback on, Wirecutter only promotes stuff they can generate a referral link to.
