On a tangent note: don’t use ultrasonic humidifiers. Unless distilled water is used, they create a shit-ton of pm2.5 particles. Use evaporative humidifiers (just disks with myriads of small notches for water to cling on and a fan): https://us.smartmiglobal.com/pages/smartmi-evaporative-humid...

How did we survive the last 3.5 billion years?

Quite poorly in fact

A humidifier needs network capability incase someone discovers a new version of water, or for the manufacturer to be able to patch remote exploits. https://xkcd.com/3109/

I'm all for KISS.

But in a rare instance, xkcd is missing the point here. People do not live in their rooms 24/7, but they do want to be able to, e.g., turn stuff on or off remotely, or based on environmental conditions (turn on/off based on outside sensors or the current electricity price...) or to get status alerts ("tank empty, refill").

Now, I do that via Home Assistant and keep anything "smart" on a highly-restricted vnet ... but not everyone is a geek. While the standard implementation (some cloud service) comes with a bouquet of problems, it basically acts as a simplified Home Assistant, and ultimately as a necessary crutch. Preferably we'd be in IPv6-land, where ISPs would not NAT everything to death and we could talk to our devices remotely without an intermediary ... but well ... it cannot be helped.

"You're not going to need it" and "In my time, we just flipped a dumb switch" is paternalistic hogwash, not clever social commentary. Back in my days, we also didn't need satnav (just read a paper map), or cell phones (write them a note, leave it on the fridge, nothing is so important to demand imminence), or dishwashers (just do your dishes by hand)

I have had one running a few feet from the monitor for over a week and there hasn't been any notable increase in PM2.5 particles.

What's your PM2.5 baseline, and did you measure TDS in the water?

I found this too. I wonder why they don't just accept a PUR water filter on the input side. I also wonder why mini-split heating systems drip and pool water outdoors instead of pumping that distilled water back indoors for humidification.

It's funny in an ironic way because the original purpose of air conditioners was to remove humidity from the air, the mechanism used was to cool the air down thus forcing some of the moisture out. The general public quickly caught on that having cool air was nice in it's own right and that is the main purpose these days. however the dehumidifying function is still sometimes used, people are surprised when their air conditioner turns on at the same time as the heater (why are they fighting each other?) but that is because the system is trying to remove moisture from the air before it is heated. Mainly seen in cars so the windows don't fog up.

Probably something wrong with me but I just find it humorous trying to add moisture to a system designed to remove it. Really a reasonable request however, depending on where you live the air can get quite dry.

Since Nov it's been fluctuating between 5-7 ug/mg, with a few spikes hitting 9 and 10. At this moment its a 6.

I haven't checked the TDS but when I used a water test strip for an aquarium early this year it was in the hard water range.

They are referencing https://www.venta-air.com/en_us/product/lw45-original-humidi... I also have one and love how easy it is to clean.

For $500 it better clean itself

I bought two Ventas well over a decade ago, and they still work as well as the day I bought them. They're an expensive initial investment, but IMO worth it over the long run.

They are also mechanically simple, so I trust that if they ever break, I will be able to repair them.

Tangential rant: It’s becoming hard to buy dumb appliances.

I was looking at robot vacuums, and most need internet connection at least for setup - by which point it’s already uploaded your floor plan and who knows what to the cloud.

The project was recently discussed on HN as well. It has its issues but it works.

Obviously all these smart appliance are about remote management, but I have to question how much usage it's getting in real life. My parents got a few smart devices for their holiday home, as my dad didn't want to drive 45 minutes both ways to check up on things during the winter. I think he probably ended up spending more time managing the IoT stuff that he ever did driving.

It create to have the option to manage something remote, but when remote become the only option, the usability takes a dive. When I have to go find my phone, unlock it, find the app, possible update the app, find the right setting or menu, stare at "Failure to connect to device", and whatever else might go wrong, it's quicker and easier to just manage the device directly. We got rid of our robot vacuum clear, because it's literally quicker and better to go get our 20 year old regular vacuum, and the floor is done in 3 minutes, not the 20+ the Roomba needs (and I needed to clear the room for it). When we used the Roomba, 99% of the time I pushed the "Start" button on the device, because it's way quicker than using the app.

There's a place for smart devices, but they need to be much better and have local controls.
