Not really "for life" (in that sense), but I missed the first thread so I'll put it here.

After a lot of research, I got some Airpro masks[1] ($40-50) for Christmas 2020. My original unit is still going strong today. In short, it's a wearable HEPA filter that pumps highly filtered air into any standard N95 or KN95 mask.

In theory it gives better filtration (from higher filter efficiency and positive pressure), but mainly I love it because it eliminates hot mask face.

My usage tips after 2 years of use:

* I bring my own N95 masks that I like, the (now discontinued) Harbor Freight N95 masks. Choose one you like. I change it about once a month, after (gasp!) converting the head straps to ear loops. Easier to eat that way: open, shovel, close.

* The design is made to accommodate a carbon pre-filter, so I just cut rectangular prefilter a out of standard surgical masks. Changed monthly, I still haven't needed to replace the original HEPA filter.

* Be sure to check out the review from "TX gadget nut" for how to seal the internal leak paths.[1] I potted the entire board with food-grade caulk, since I noted small through-holes in the PCB.

* To protect the silicone hose from strain, I hang the unit sideways on the included lanyard.

* If you're really obsessive, you can use a small file to remove the mold lines inside the outlet port, slightly reducing the pressure drop.

Fingers crossed, but so far it's been very effective and comfortable. I estimate it's about 15¢/day.

(not exactly BIFL with all the consumables, but before I used an N95 a week so I'm way ahead)

Wozniak was just on Steve-O’s Wild Ride promoting this (it was one of his show and tell items)

Very interesting! If Woz likes it, I must be doing something right...

Found it: https://youtu.be/CRi8r0XQFHU?t=5402

I saw him speak shortly after the Intel Mac release, and I got him to sign my computer "Woz Inside." Inaccurate, but he had a great sense of humor about it.

when do you wear this?
Re:Ask HN: What are some of your “buy it for life” purchases? by schiffern on Saturday January 14, 2023 @04:38AM (#34378811)
Any indoor public space, and sometimes outdoors if the air's bad. With ~zero hedonic disincentive, it's easy to wear it all the time.

I get about one inquiry a month, usually at the store. People seem to like it, especially when I mention the comfort benefits.

Do you live somewhere where the air is particularily bad?
Re:Ask HN: What are some of your “buy it for life” purchases? by schiffern on Saturday January 14, 2023 @05:04AM (#34378944)
Mostly fine, except when neighbors fire up the woodstoves. AKA all winter.

Are you on constant immunosuppressants or why do you wear this all the time?

Do you plan on wearing a mask for the rest of your life?
Re:Ask HN: What are some of your “buy it for life” purchases? by schiffern on Saturday January 14, 2023 @07:28AM (#34379749)
By that, you mean in public indoor spaces? Maybe, maybe not! That's the great thing about personal choice. :)

That's like saying "Do you plan on wearing pants for the rest of your life?" To me, a mask isn't any more burdensome.

I find it’s actually pretty good to compare it to sun protection. Kids used to run around in the sun without sunscreen, still can in some places/times to a certain amount… but we collectively sort of realised the risks and so most people (at least in Australia) use sunscreen to avoid the easiest cancer to avoid, Melanoma. There are people who have a natural immunity of sorts due to darker skin and melanin concentrations, there are people that deliberately expose themselves for perceived benefits like “getting a tan” because “it looks healthy” and there are older people who got lucky and ran around unprotected who think it’s a rip off by big sunscreen and don’t see the point while also no longer needing it due to age and lifestyle changes out of lots of direct UV exposure.

I mean I very much understand the other commenter line of questioning but any questions related to mask wearing will be highly dependent of where you are from.

I’m from Western Europe and mask wearing both never was political, was well followed during the much more stringent restrictions we had at the peak of the epidemic and has virtually disappeared from the past two years.

It’s a very different attitude that what it seems to be in the state but our relationship with diseases is already culturally extremely different than what it is in the USA.

A mask cannot be more comfortable than no-mask unless you're in some very cold environment. Suggesting that a mask in 2022 has anywhere near the utility of pants is off by orders of magnitude.
Re:Ask HN: What are some of your “buy it for life” purchases? by blackshaw on Saturday January 14, 2023 @06:34PM (#34385190)
I'd honestly rather not wear pants for the rest of my life than go back to wearing a mask every day.

As you may note, that's not what I said.

> Suggesting that a mask in 2022 has anywhere near the utility of pants

Didn't say that either.

It's simply strange to me that people get so worked up over it, just like it would be strange if people got super worked up over wearing pants.

In my experience, absent of the 'hot/stuffy mask face' it's no big deal. YMMV

Its a political statement/dogtag for them.

Or maybe even, as they said quite plainly, "at-risk family members".

Personally I wouldn't wear a mask any more; as others have said I think there comes a time where unless there's a specific heightened risk you have to accept that you either stop at some point or wear one for the rest of your life.

That said, I have immediate family who are extremely immuno-suppressed. I either wear a mask, or every day I increase the risk of killing them. So I wear a mask.

Sometimes the argument is pointless. The "other side" may even agree with you. Yet life often makes a mockery of our choices and forces behaviours upon us.

Thanks! I won't need a mask anymore, because the irony is killing me.

Do your at-risk family members have the same strict mask adherence as you?

I ask because this very much applies to me. I have very at risk family members and if by wearing a mask daily I make them 1% less likely to die, that's worth it to me. But these family members themselves have stopped wearing masks... That doesn't mean my masking will do nothing, but when they're not even trying I find it hard to justify.

I had one, then switched to an Ultramasx, riding the bus for hours a day in peak covid without issues.

That company went out of business as far as I can tell though, so it will be back to the Airpro when I run out of filters, if I can find it.

Re:Ask HN: What are some of your “buy it for life” purchases? by GoldenMonkey on Saturday January 14, 2023 @06:08PM (#34385039)
You do know that masks do nothing. There are no studies proving it’s effectiveness. And there are studies w negative effects (teeth, jaw issues, sinus infections)

Well, in india the purple masks were more effective than the red ones;)

Good on you mate for keeping yourself and your loved ones safe !

I must say I admire your ability to keep cool when the minimizers creep out of the woodwork.
