#airpurifiers — Public Fediverse posts

If you have a Levoit Core 400s air purifier, you can flash it with ESPHome.

The guide says: To get to the microcontroller, it's necessary to open it from the bottom.
It's actually easier if you don't care too much about its aesthetics.

There is a gray ring at the top and black latches on the inside behind the gray ring. You can push these latches in by using 2 sharp & thin knives.

One knife to lift the ring and a second one to push in the latches. Parts of these latches will break! But don't worry, it will reassemble just fine.

If you take the bottom-up path, you will have to extend the internal cables. Otherwise, you won't be able to reconnect the PCB to the unit.

Please know, you will have to take the bottom-up path halfway, otherwise you cannot see the inside latches. You have to detach the upper part from the lower part.

What a dumb design choice by #Levoit!

Great job on this, @tuct.

get air filters. Don't like masks? Can't wear respirators? Filter your air!

Push your local school(s) to fundraise for air filters.

Remember the news article two weeks ago reporting on an air purifier study in Finnish daycare centers? The one that lasted 2 years and found an 18% reduction in children's illnesses.

The researchers have now published a preprint:

The DARK TRUTH about #AirPurifiers

#consumerknowledge

Any recommendations for reliable air purifiers for use in a school hall (hired, not school function) with 40-50 people?
Needs to be something available in NZ. Thanks!

🇫🇮 Finland: Air purifiers used at daycare centres cut kids' sick days by a third

"It would be a big savings if we could get rid of 30% of sick days spread by children, as well as the illnesses that go home to parents," Dr Sanmark said.

#covid #kids #airpurifiers
I have read that modern air purifiers are very effective at removing virus particles from the air, viruses like covid, flu and RSV. Cold weather is coming and your kids will be getting sick, and you will be getting sick because your kids are sick. If parents banded together and furnished every classroom in their child's school with an air purifier a lot of illness can be prevented. Fewer lost teaching moments. Fewer lost hours at work. My kids are grown, so you might say I have no dog in this fight. But it's a smart thing to do and I would have been all over making it happen when I had school age children. It's certainly worth a try.

Hear, hear.

Also, in the case you're looking for #airpurifiers, I actually recommend Blueair 311, they're simple in function but very effective and quiet on the lowest setting. Super light to carry and can easily be moved around.

The Mila is more expensive, visually good looking, and has all the gizmos because it has an app. It's cool to see AQI in your area and the state of the room it's working in. We put ours in the basement (long story) bc air isn't so fresh, but clearly outdoor air seeps in.

It seems like our new #HEPA #AirPurifiers are drying out the air, leaving us with sore throats when we wake up in the morning. This is making us worry we've got #COVID, which alas is possible because our daughter went on an outing last week with a woman who tested positive Jan. 1, and that woman's daughter slept over at our house Dec. 31. So of course I had a nightmare last night in which I tested positive for COVID. 😢 I tested negative this morning in real life. Let's hope that continues. 1/2

If people there need #AirPurifiers and cannot afford to buy them, building their own might be an option
