Alrighty, don't a lot of people already do this? Sometimes I'll do both an air purifier white noise and some music or something from myNoise

The Austin Air HealthMate is great as a noise machine. Very loud. It’s a HEPA filter and lasts 5 years. Never seen any other that lasts that long, but you pay for it upfront. after-market replacements are $250-300 for another 5 years.

I have that machine. It seems better at filtering chemicals and VOCs but not great at filtering particulates. It gets rid of odors very well but my PM2.5 meter barely budges.

Yeah, it's a completely different kind of air purifier than the "tape a HEPA filter to a fan" ones, which is why it costs $1,000 instead of $150.

An air purifier is a good addition to a kids bedroom.

I got one during Santa Cruz wildfires in 2020 and now the kids have a pavlovian reflex to sleep once that gets turned on.

Ikea makes an air-purifier table, which is a end-run around it being a useless box in the room when switched off.

It's fairly expensive, not as good as a purpose built one, but it blends into the average room pretty well.

I've considered an air purifier for allergy reasons, but...

>removes smoke and infectious particles

Where do people live that they need to remove such things, 18th century London?

Anywhere in the US west of Texas and most of Canada.

Almost anywhere now in North America or Europe during the summer.

Doesn't even need to be during the summer.

Wind blows smoke around. There are currently fires in northern Michigan that are affecting the air quality in Chicago, which is 350+ miles away.

As an allergy enjoyer there is no air too pure.

My allergies became generally better at all hours just from sleeping in super cleaned air.

Why? Reducing baseline inflammation perhapse? Maybe decreased inflammation during sleep helps too, improved breathing? idk. Whatever it is this organism seems to prefer it.

Even when exposed to allergens during the day the run up to sneezing is much slower or doesn't happen.

I bought a large soldering iron air purifier and it turns out to be great; it has a continuious speed selector, easy to replace filters, and very pleasant spectrum. I like it better than the air conditioner, which cycles on and off noisily.

One of the best air purifiers you can get (linked in the above writeup) uses PC fans and a custom controller where you can control the speed/volume: https://housefresh.com/best-air-purifiers-we-tested/#2-best-...
LTL_FTC•18m ago
Those fans will not have sufficient static pressure to be useful. These makeshift purifiers may be great in a pinch (wildfire season and stores are all out), but far from the best.
turtlebits•32m ago
Does that mean your air doesn't get filtered if you stop or decide to turn down the white noise?

I prefer having quiet air filters that I can run all day (based on air quality) instead of noisy ones I only use at night.

kube-system•14m ago
Many air purifiers are silent on lower settings and louder on higher settings. If I want noise I turn mine up. If I want less noise I turn it down.
alistairSH•5m ago
If you turn it off, sure.

I have one in the bedroom. On low, I barely hear it during the day (extra ambient noise from outside) but at night the white-noise is subtle but effective. That said, I don't like "loud" white noise, just a quiet hum.

senderista•8m ago
An air purifier is the best noise machine for me, much better than the white noise machines with the tinny speakers. Even the brown noise setting on those isn't nearly deep enough to let me sleep.
