Ultrasonic humidifiers just disperse water as a fine mist. The \"humidification\" happens when this mist evaporates

Last October I installed an Aprilaire 500M whole house humidifier on our furnace and plumbed it in to the reverse osmosis water system.
Checked the water evaporator panel this spring and it still looked brand new.

WTF is a \"reverse osmosis water system\"? Do you live in a clean room?

It\'s a cheap way of getting a lower mineral content in your water. Some cities use big reverse osmosis plants to get drinking water from sea water. Sydney has one, but it costs money to run, and only gets turned on during droughts. With sea water, about half water going into the plant emerges as drinking water while the other half carries away the brine concentrated out of that water.

Gardening is central to my favorite book, Wodehouse\'s \"A Damsel In

I recent read \"Finding The Mother Tree\" which is about the fungus

Yes, plants love CO2. It\'s good for the planet and we need more.

Does it literally evaporate the water?

Yes

Is there any unused water
discharged?


Yes, approximately one drop per second exits the drain tube when the furnace blower is on and the humidistat is calling for more humidity.

Makes sense; that\'s where the minerals exit.

I seached EBay and found one that seems to be like it. The shipping

There are some for cheaper.


I found a steamer at Amazon. It has a small chamber with a heating
element

https://www.amazon.ca/gp/product/B07GQ2CF4T/

The calcium appears to stay in the water and attaches to the element,
just like in an electric kettle. Boiling vinegar for a few minutes
should clean it out. I\'ll try your trick of turning power off before
the chamber is empty.

The nice thing about the DeVilbiss 145 is that the water is heated by
passing AC through it (the electrodes are directly connected to the
mains), so that happens automatically.

Yes. That would make it easy to DIY, but impossible to pass UL.

I very rarely need to use it for more than a week at a time, so I\'ve
never had it crud up on me. Dunno what it\'s like in continual use.

As I think of it now, the output will drop since the current decreases as
the water level drops. This will make it impossible to maintain a constant
humidity level. Do you ever monitor the humidity? Digital hygrometers are
very cheap on EBay. For example:

https://www.ebay.com/itm/363794102205

I have a bunch that I use everywhere, and I have given a bunch away. I even
monitor the humidity in the vegetable bin in the fridges. (I have two) You
really need these in Canada when the temperature gets down to -30C.

The problem with this method is trying to control the output. It claims
to be able to adjust the output to give 24 hrs of run time. This would
make it identical to my ultrasonic mister, which keeps the humidity at
40%, which is perfect.

Thanks very much for your post and helpful reply. Hopefully this will
get rid of the fine coating all over everything.

Not to mention all the mould spores and Legionella.

The dash of bleach used to prevent slime buildup on the regulator valve
would eliminate any bacteria or viruses. I don\'t know where any mold spores
would come from. We get our water from an acquifer that filters lake water
through thousands of feet of silt and sand.

Incidentally, I caught Legionella on a trip to Singapore. Almost died

John Larkin has been reading Anthony Watts\' climate change denial propaganda.

Plant\'s appreciate CO2 but they are much more interested in water. Give them more CO2, and the number of stomata in the leaves go down - they don\'t need as many of them to let in the CO2 they actually need, and fewer holes for water to diffuse out of mean that they can hang onto more water (which is harder to get hold of).

John Larkin gets told about this from time to time, but he seems to forget it.

How long does it take to evaporate a gallon?

My ultrasonic mister takes about 24 hrs to evaporate 4 litres, which is
1.06 gallons. This raises the humidity from 20% to 40% and stops the
chapped lips and sore sinuses. The white film that covers everything is
harmless and is a small price to pay, but I wonder if a steamer could
do as
well.

It would increase the temperature, so you\'d then need to use AC which
would remove the humidity!

Not a big problem in the parts of Canada that are very dry in the winter.

No need to mess with borax. A simple incadescent light dimmer can adjust
the output to any level desired. This should give better repeatability of
the steam output and more predictable results.

The borax speeds it up, whereas the dimmer can only slow it down. A
variac could do both. You\'d also want to be careful to avoid any
residual DC from triac asymmetry.

Not usually. The vapourizer output is more nearly constant than you\'d

out of the water.

I find no such problems. All it does is make the air more humid. Why
the fuck would that cause deposits?

because it doesn\'t turn the water into vapor, it turns the water, and
what ever minerals in it, into tiny droplets and spread them in the air

I am 80 and live in Canada, a cold climate. When the temperature is low, there
is very little humidity in the air. This means the relative humidity indoors is
very low and gets down to 20% or below.

Low humidity causes chapped lips, sore sinuses, and greatly increased
vulnerability to virus and bacterial infections. 30% to 50% RH solves these
problems.

I got mine for the parrots.

I bought an Ultrasonic Top Fill Humidifier from Amazon Canada:
https://www.amazon.ca/gp/product/B09KRCS7R7

This has no problem maintaining the humidity at 40%, but I discovered some
issues.

1. Ordinary tap water contains calcium. This covers everything with a fine dust.
It looks awful but it is harmless and is easily wiped off. Obviously, you breath
this in.

I\'m in a soft water area, virtually none of that. I\'m surprised water companies aren\'t required to remove that shit so it doesn\'t scale up kettles., washing machines etc.

Our water company adds limestone or something to protect the pipes.
The water supply here is naturally a bit acidic.

Limestone is Calcium carbonate, CaCO3.

This leaves a white film all over everything in an ultrasonic humidifier.

A boiling water steamer leaves the calcium on the heating element.

The calcium is removed by boiling a small amount of vinegar in the chamber.

Calcium carbonate : CaCO3

The calcium appears to stay in the water and attaches to the element,
just like in an electric kettle. Boiling vinegar for a few minutes
should clean it out. I\'ll try your trick of turning power off before
the chamber is empty.

The nice thing about the DeVilbiss 145 is that the water is heated by
passing AC through it (the electrodes are directly connected to the
mains), so that happens automatically.

Yes. That would make it easy to DIY, but impossible to pass UL.

I very rarely need to use it for more than a week at a time, so I\'ve
never had it crud up on me. Dunno what it\'s like in continual use.

As I think of it now, the output will drop since the current decreases as
the water level drops. This will make it impossible to maintain a constant
humidity level. Do you ever monitor the humidity? Digital hygrometers are
very cheap on EBay. For example:

Not usually. The vapourizer output is more nearly constant than you\'d
think, because the concentration of dissolved solids goes up as the
water level goes down. It does decrease when the electrodes are nearly
out of the water.

I have a bunch that I use everywhere, and I have given a bunch away. I even
monitor the humidity in the vegetable bin in the fridges. (I have two) You
really need these in Canada when the temperature gets down to -30C.

The problem with this method is trying to control the output. It claims
to be able to adjust the output to give 24 hrs of run time. This would
make it identical to my ultrasonic mister, which keeps the humidity at
40%, which is perfect.

Thanks very much for your post and helpful reply. Hopefully this will
get rid of the fine coating all over everything.

Not to mention all the mould spores and Legionella.

The dash of bleach used to prevent slime buildup on the regulator valve
would eliminate any bacteria or viruses. I don\'t know where any mold spores
would come from. We get our water from an acquifer that filters lake water
through thousands of feet of silt and sand.

Incidentally, I caught Legionella on a trip to Singapore. Almost died
untill the doctor called and asked me to come into his office. Turns out he
had misread my chest X-ray and decided to check it again. If he had not, I
was a goner. Actually, it\'s not a bad way to go. Very peaceful, with
beautiful music on the way out.

What\'s wrong with posting to non-uk newsgroups? Do you think US

Are you really so stupid that you cannot grasp that he was referring

Yes, he\'s not that bright. Most people killfile him.

It is a rhetorical question. I am sure you are just a fucking joy to
