As usual dipshit (serendipity) you dont know what your talking about.....
To the original poster, "cold mist" humidifiers work with ultrasonic energy,
it literally "cracks" the minerals in the water. the use of distilled water
ONLY will stop the white powder.
"warm" type humidifiers WILL NOT produce the white powder at all. Distilled
is still preferred as you will get calcium and lime buildup in either
Serendipshit is giving you BAD info, adding vinegar WILL NOT stop the dust,
will make the house smell like a salad..., but to trailer
trash.(Serendipshit) thats a major plus.
Fraid not, it just creates a mist of the water ultrasonically and that
sees minerals that are in the water end up in the air as well, where
they deposit on surrounding surfaces as the water evaporates.
Use distilled water. I recall a high school experiment where a pot
of water was boiled down to 1/4", refilled, and boiled again down to
1/4". The remaining water was a filthy-looking sludge. That was in
Cleveland, Ohio where the water is very hard. The deposits on your
humidifier should be cleaned off per manufacturer's directions (or you
can use vinegar).

The dust is the salt in the water. Nothing you add to the water will remove
salts, including vinegar. There are two possible solutions to the
problem -- use distilled water or replace the humidifier with one that
evaporates the water rather than spraying it into the air. In the long
term, replacing the humidifier with an evaporative unit will probably be
cheaper. Large evaporative units cost about $100, room sized units about
$50 in the U.S. I use a larger unit for my 1200 sq. ft. house. It uses
from 3 to 5 gallons a day here in the desert southwest (mild, but dry,
winters). --- SJF
Yeh! I remember them now. Had one many years ago and it cost about $10.
Pretty sure you're referring to the boiler type -- gallon jug, two
electrodes and the resistance of the water heats it to generate steam. This
is the one that requires addition of salt if your water is too pure.
My reference to evaporative humidifiers was to the currently popular type
that draws air through wet filter pads. Guess the electric boilers are
still around but I overlooked them. --- SJF
The dust is from the mineral content of the water - it's probably calcium,
but I've never heard it referred to as "chalk" in this context. You can
either use distilled water which would be free of mineral content or switch
to a vaporizer-type humidifier, one which in essence boils the water and
emits steam. With this type, the mineral residue is left behind in the
That's what comes from using an ultrasonic humidifier. Dissolved
minerals, in my water its mainly calcium and magnesium sulphate, is
carried in the fine mist. When that mist water evaporates the mineral
content is deposited around the humidifier.
My solution for humidifying the house is to have a lot of house
plants. If they thrive it means their respiration had kept the air in
the correct humidity. I had disconnected the power humidifier in my
forced air furnace because of lime buildup and because the water in
the water tray was often slimy. That slime is probably mold and had
caused respiratory problems.
Yes, I believe so. You can keep a static, low-level algaecide in the
water. Such products are usually used (as slow dissolving tablets) in AC
condensate drip pans and are actually a quaternary ammonium chloride
When I die, I want to go where dogs go!
Not likely as the furnace draws air from the whole house to
recirculate. The sponge pad and the water tray make an excellent
growth medium. The nutirents were probably from all the dander and
other stuff picked up from the air. The humidifier disperses several
gallons of water a day so there is no effective way of neutralizing
the water tray contents either by adding chemicals. Who wants to
breath chemical vapours anyway. I am handy enough to put in a
home-made UV light source but thought better of it. The house plants
idea is a lot more satisfying. Plants give of as much water as is
required by them to thrive. If they thrive I do. They make the whole
hose look a lot better too.
