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,
sickness,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
soaked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

19
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
needstobereplacedbeforeusingtheunit.
•Exchangethedemineralizationcartridgeafter1-2
monthswhenyouuseveryhardwater(forsofterwater
after2-3months).Nomatterhowhardyourwater
is,exchangethecartridgeattheverylatestafter6
months.
•Don’tusewaterfromapre-installedwatersoftener,
orsodiuminsteadofcalciumwillbeemittedfromthe
unit.Usedistilledwaterinsteadandremovethedemi-
neralizationcartridge.
•Forveryhardwaterareasuseonlydistilledwaterand
removethedemineralizationcartridge.
•UseReverse-Osmosiswater(R-Owater)insteadof
distilledwaterandremovethedemineralizationcart-
ridge.
•Cleaning light is illuminated (digital models)
 Switchofftheunitandunplugit.Emptythewaterin
thebase.Rinsethebasewithhot/cleanwater.Donot
submergethebase!Visuallyinspectthebasefordirt
ormineralbuildup.Ifsoftwaterisuseddecalcifying
theunitevery4weekswithECalissuggested.Ifhard
waterisusedtheunitshouldbedecalcifiedevery
2weeks.Donotforgettoresetthecleanlightafter
resetting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
ineverycorneroftheroom.Theunitshouldnotbe
placednearaheatingventoraradiatorastheheatwill
absorballofthemoisture.
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
conditionintheroomhasaninfluenceonthehumidity.
Reasons for low humidity level:
•aircirculationisveryhigh(airisfullyexchanged
severaltimesperday–thehumidifierneedstostarts
itsworkfromscratch)
•insulationofhome(seeaircirculation)
•openspacewithhighceilings(notonlythefootageof
theroomcountsbutalsotheheight)–high-risebuil-
dingsrequiremorehumidification.
•openwindows–workssimilartoaircirculation(ifitis
verycoldoutsidedon’topenthewindowmorethan
2timesperdayfor3minutes)
•bigdifferencebetweenoutsidetemperatureandinside
temperature–thecoldertheairthelessmoistureit
iscapabletoholdandthemoretheairisheatedup
theloweristhepercentageofrelativehumidity(=the
amountofwatervaporintheair,comparedtothe
amounttheaircouldholdifitwastotallysaturated)
•positionoftheunit-ifitisplacedclosetoadoor,
windoworairvent.Thisincreasestheaircirculation.
Q.Tank is leaking
A. Checkifthereareanyhairlinecracks.Droppedunitsor
watertanksthatarecrackedwillnotbecoveredunder
thewarranty.Pleasecontacttheretailertheunitwas
purchasedfromincaseyourunitarrivesdamaged.
Q.Placing the face in the mist
A. Itisnotrecommendedthatanybodyplacestheirface
inthemist.Itisanelectricalproductandshouldnotbe
playedwith.
Q.No mist / unit is not working / empty indicator
keeps flashing
A. Fillupthewatertank.Checkifwaterisflowingthrough
thedemineralizationcartridge(attachedtothewater
tankcap).Ifthewatertankisfullbutthereisonlylittle
waterinthebaseitindicatesthatthewaterisnow
flowingthroughthedemineralizationcartridge.
•Waitfor15minutestoallowthemisttocomeoutof
theunit.
•Iftheunitisnotworkingandtheemptylightisnot
flashingyoumighthavesetthedesiredhumiditytoo
lowandthecurrenthumiditylevelintheroomis
higher.Thatiswhytheunitswitchesoffautomatically.
•Iftheemptyindicatorkeepsflashingandthetankis
full,thewaterisnotflowingthroughthecartridge.
Exchangethecartridgeorthegranulesinthecartridge
after2-3months,inareaswithhardwaterexchange
thecartridgeafter1-2months.However,thedemi-
neralizationcartridgeandorthegranulesmustbe
exchangedatthelatestafter6monthsortheunitdoes
notreachitsfullperformanceanymore
•Ifthegranulesarenew,seethefollowinginstructions:
•Makesurethecartridgeand/orgranulesweresoaked
for24hours,drygranulestakeevenlongerforwater
tofilterthroughthecartridgeandintothebase.Next,
pleaseremove2tablespoonsofgranulesfromthe
cartridge,andthrowthemaway.Whentherearetoo
manygranulesinthecartridgeitdoesnotallowwater
toflowfromthetanktothebase.

Q.Water tank cap is too tight to unscrew
A. Thiscouldbeacauseoftheairpressurewithinthe
watertank.Depressthespringonthebottomofthe
watertankcaptoreleaseairfromthewatertank.
Continuetodothisuntilyouareabletounscrewthe
watertankcap.
Q.Unit is running intermittently.
A. Howlonghasitbeensincethecontentsofthecart-
ridgewerereplaced?If2-3monthshavepassed,itis
timetoreplacethecontentsofthecartridge.However
thedemineralizationcartridgeandorthegranules
mustbeexchangedatthelatestafter6monthsorthe
unitdoesnotreachitsfullperformanceanymore.
•Ifthecontentsofthecartridgewerejustreplacedthere
areprobablytoomanygranulesinthecartridge.Re-
