Question about Swiss Air-O- 7135 Warm Mist Antimicrobial Humidifier Humidifier

Noisy ultrasonic humidifire

My humidifier humidifies ok but makes a lot of noise. There is no lose parts anywhere. The little grey circle that makes mist seems to have some crust on it which doesn't come off even with vinegar or special solutions. I've changed the cartridges and filters but maybe the water is very harsh here...

The grey circle (diaphram) needs replacing. Try Maplin electronics.

Noisy start-up

If it is a vibrating motor noise, then some oil may help but make sureit doesn't drop into the tank. The little Motors used in these things have a limited lifetime and bearings and corrosion a of insulated iron plates that the copper wire of the motor coils wrap around do tend to corrode and lose their efficiency.

Otherwise, try a bit of foam padding to isolate the tank from the motor assembly - there might be some slight vibration there.

Humidifier will produce mist for a min then stop If you look you can see it producing mist within but it will not come out of the top Walgreens cool mist ultrasonic humidifier

I have had times where my Crane humidifier won't produce mist if I haven't turned it on for several days (4+) or more. The water that sits in the reservoir may develop a film on the ultrasonic element which inhibits the creation of the mist to come out the top of your humidifier. I would lift off the tank and empty the reservoir. Then VERY GENTLY with a piece of paper towel, wipe the ultrasonic element (looks like a disk the size of a quarter at the bottom of the reservoir) to clean off any film. Then replace the tank and let the reservoir fill up the tank and try it again.

If your humidifier runs properly for a minute and then makes a whirring noise and goes silent (like the motor stopping), then it's a motor problem. The humidifier motor may have gone out of alignment due to bumping or rough handling of the humidifier when cleaning or emptying it. If that is the case, you will have to empty the humidifier reservoir, unscrew the base, and find the screws holding down the motor and check for misalignment. Loosen them a little and put it back together and try again.

Best of luck

Crust of sediment in hot water pot

Hi, Go to your grocery store and buy some cream of tartar which you can find in the spice section, it is a white water soluble powder. Dissolve about a teaspoon full in a pot of your coffee water, put in a filter with nothing in it and cycle the water through the coffee maker, if it is really scaled up do this a couple of times, discard the filters which probably will have some little white and yellow chunks in it and this should clean up the inside, you may have to soak the pot in the warm water with a little stronger solution. Good Luck!

Humidifiter doesn't humidify

have you checked the misting nozzle? if its clogged place it in (CLR) and let soak, I would try to run a little diluted (CLR) through the unit as well, to remove any calcium build up, that is the most common problem with most humidifiers, also check to make sure the pump is working, if not you will need to replace the pump, hope that helped

Humidifier makes a huge noise and no mist

According to the Crane's Troubleshooting section:
The power light is green but there is no mist being emitted:
- Check that there is water in the tank.
- Check for possible lime deposits on the water level sensor or the nebulizer.
- Make sure that nothing blocks the vapor output slots.
- Check that the fan vent on bottom of humidifier is not blocked.
- Empty the humidifier and rinse the water basin with cool tap water and allow to dry for 15 to 30 min.

This next part may or may not be relevant.
Humidifier power light is staying red and not turning green. Or, Humidifier is working then stops:
- Ensure that water level sensor is assembled properly.
- Clean water float.
- Call service center and request replacement water float.

Barring that, here is the service center contact info:

I have the evenflo cool mist humidifier, model # 758100. There should be a model number on the unit. As far as replacement filters, you can buy the Holmes humidifier filter, model # HWF62. It's compatible with Evenflo. I bought a 2-pk at Target for $15.99. Hope this helps.

The humidifier doesn't make enough vapor

Soak it with vinegar for several hours then use a soft nylon bristled brush to scrape off the minerlized crust and rinse. You probably need to replace the silver stick & mineralization cartridge more often.
