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 cart-

ridge (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

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EZCalissuggested.Ifhard

waterisusedtheunitshouldbedecalcifiedevery2

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

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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-

veral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
