General Humidifier Questions
Q.Why isn’t there enough moisture in my room?
A. Howoftendoyouruntheunit?Iftheunitisonlyrunat
night,thenduringthedaythemoisturelevelwilldropif
moistureisnotconstantlyaddedtotheair.
Q.Do you leave your door open or closed when the
unit is running?
A. a) Byleavingthedooropen,thisallowsmoistureto
leavetheroomandgointootherareasofthehouse.
If you would like the moisture to stay within one
specificroomyoushouldconsiderclosingthedoor
whiletheunitisrunning.
A. b) Wood,leather,carpet,curtains,andothertypesof
fabricsoakupalotofmoisture,thusnotleaving
enoughmoisturefortheair.Ifthewindowisleft
open,thenthisallowsmoisturetoescapetheroom.
Anotherfactorisalotoftimestheunitisplacednext
toaheatingdevice.Theideaisthattheairblowing
intotheroomwillquicklyplacemoisturearoundthe
room.Unfortunately,thisconceptdoesnotwork
becausethehotaircomingoutofaventwillsoak
upmostofthemoisture,andnoneoftheairwithin
theroomwillreceiveany.
Q.How much moisture do I need in my room?
A. Suggestedhumiditylevelsarebetween40–60%.
Q.What are the effects of too little or too much
humidity?
A. Dryaircancausedryskin,staticelectricity,outoftune
musicalinstruments,increasedlevelsofdust(dryair
causesdusttorise),damagetowoodenobjects(dry
outandeventuallycracksappear),discomfort,sick-
ness,anddriesoutnasalmembranes.
Over-humidifyingtheaircancausemoldandwallpaper
topeel.
Q.Why do I need a humidifier when I can just open
my window?
A. Themoisturelevelwithintheoutsideairisnothigh
enoughtohumidifyaroom.Thecoldertheairtheless
moistureitiscapabletohold,andthemoretheairis
heatedupthepercentageofrelativehumidityislower.
Relativehumiditymeanstheamountofwatervaporin
theair,comparedtotheamounttheaircouldholdifit
wastotallysaturated.Thedifferenceishigherbetween
outsideandinsidetemperatures;morehumidification
isneededbecauseofthedryairintheroom.
Q.Where should I place my humidifier?
A. Theunitshouldbefree-standingandnotclosetoa
wall,window,door,orthermalbridgesothatairmay
circulatearoundtheunit.
Ultrasonic Frequent Questions
Q.Why does it say open/close on the demineralization
cartridge cap?
A. Thosedirectionsarethereincaseyoudecidetouse
therefilloptiontoreplacethegranules;thepurposeis
forhowtoopenandclosethecap.Ifyoudidopenthe
capbeforeplacingitinthewatertank,youwillmost
likely notice that there are granules in the water tank
andthebaseoftheunit.Immediatelyturnofftheunit,
andemptythewateroutofthebaseandthewater
tank.Beginremovingallgranulesfrombaseandwater
tank.Usebrushtocleanaroundmembrane.
Caution:Donotdisposeofgranulesinsink!Used
granules must go in waste!
Q.I just replaced my cartridge, and the contents and
water in the base has turned a blue-green color.
A. Thissometimesoccurswhenthecartridge,oreven
thegranules,arereplaced.Thisdoesnotoccurwithall
replacementcartridgesorgranules,andisareactionof
watercontentandtheUltrasonicvibrations.Thisisnot
anindicatortoreplacethecartridge.
Q.There is no fill-line on the water tank, how far
may I fill it up?
A. Thereisnofilllineonthewatertank,anditmaybe
filledallthewaytothetop.
Q.What is the purpose of the demineralization
cartridge (DMC)?
A. TheDMCremovesmineralsfromthewatertoprevent
whitedust.Thecontentsofthecartridgeneedtobeso-
akedfor24hrspriortofirstusingtheunitsothatthey
mayfullyexpandandremovemineralsfromthewater.
ThecontentsoftheDMChavealifeof2–3months.
Thecartridgemayneedtobereplacedmoreoften
dependingonwaterhardnessandhowoftentheunit
isused.AnindicationofwhentheDMCneedstobe
changedcanbewhitedustorreducedamountofmist
output.
Q.Is it ok to use distilled water with the unit?
A. Forbestresultswithyourultrasonichumidifieruse
distilled or reverse-osmosis water and remove the
demineralizationcartridge.
Q.I just replaced the contents of the cartridge and
now have granules everywhere.
A. First,makesuretherearenogranulesinthemiddle
ofthecartridge.Placinggranulesinthemiddleofthe
DMCallowsthemtoescapeintheunit.Immediately
turnofftheunit,andemptythewateroutofthebase
andthewatertank.Beginremovingallgranules
frombaseandwatertank.Usebrushtocleanaround
membrane.
Caution:Donotdisposeofgranulesinsink!Used
granules must go in waste!
Q. The directions tell me not to place the unit directly
on the floor, why do I have to elevate the unit?
A.Theideawiththisunitistoallowonetoforcehumidity
intotheair.Becauseofthis,thecarpetingorwoodfloor
surroundingtheunitmaybecomedamp.Iftheunitis
18
en
placedatleast3feetoffthefloor,themistwillhavethe
opportunitytoevaporatebeforehittingthefloor.
Q. Water does not go into the tank.
A.Inordertofillthetank,itmustbeturnedupsidedown.
Thecartridgeisplacedonthewatertankcap.Donot
pourwaterinthetubewhichisthemistoutlet.
Q. White dust is emitted from the unit
A.Whitedustparticlesaremineralsthatarebrokenupin
tinypiecesbytheultrasonicprocess.
Solve the problem:
•Soakthedemineralizationcartridgeinabowlofwater
foraminimumof24hours.Ifthecartridgeissoaked
inthewatertank,thewaterinthetankandthebase

•Don’tusewaterfromapre-installedwatersoftener,

removethedemineralizationcartridge.
•UseReverse-Osmosiswater(R-Owater)insteadofdis-
tilledwaterandremovethedemineralizationcartridge.
•Cleaning light is flashing (digital models)
Switchofftheunitandunplugit.Emptythewaterin

weeks.Donotforgettoresetthecleanlightafterreset-
tingtheunit.
Q.Reset cleaning light (digital models)
A. Thecleaninglightdoesnotautomaticallyreset.Hold
downthepowerbutton(buttonAininstructionmanual)
untilthelightstopsflashing.Thelightautomatically
comesonapprox.after14daysofpluggingintheunit.
Q.The hygrometer on unit reads a different humidity
level than external hygrometer.
A. Notallhygrometersarecalibratedthesame,andmost
areoffby+/-5%.Plusthehumiditylevelisnotthe
sameinthewholeroom.Theaircirculationisdifferent

Q.Humidity level is not changing or does not reach
the desired humidity level.
A. Ifthewatertankneedsrefillingmorethanonceper
day,theunitisworkingproperlyandtheclimaticcon-
ditionintheroomhasaninfluenceonthehumidity.
Reasons for low humidity level:
•aircirculationisveryhigh(airisfullyexchangedse-
