FAQ

• Please rinse the lid on the bottom of the tank. After you rinse it with warm water, dry it and
then push the spring on the outside of the lid, it should move easily. Check the inside of the lid
and make sure the rubber gasket is securely in place. When twisting the lid onto the tank,
please make sure that it is not over-tightened.
• On the base of the humidifier to the side of the ultra-sonic disk is a small white plastic pole with
a washer-ring around it. This is the float, make sure it moves easily up and down the pole. Tap
the base of the machine on a hard surface. This will clear any air bubbles inside of the machine
should there be any.
• Reassemble the humidifier, use room temperature water in the tank and let run for 30-40
minutes. Please make sure the humidifier is on a flat level surface, no carpeting or towel
underneath.
Does my humidifier have a filter to replace?

clean or replace
What should I do before putting my humidifier in storage?
Prior to putting your PureGuardian® humidifier away be sure to pour out any excess water and
clean out/wipe down the surface with a soft, damp cloth. Be sure to let the entire unit air dry
completely (24-hours) before storing.
How often should I clean my humidifier?
PureGuardian® humidifiers should be cleaned every 1–2 weeks, depending on use. If you have
hard water or water with a high mineral count, you may need to clean your humidifier more
often.
How should I clean my humidifier?
Instructions for cleaning your humidifier: Wash the spray cap, spray spout and water tank lid
(the lid on the bottom of the blue tank) with a mild dish washing soap, rinsing well and drying
thoroughly. The blue water tank can be rinsed with warm water and dried.
Drain any excess water from the base area. The ultrasonic disk should be cleaned frequently,
using diluted white vinegar. Let the diluted vinegar soak in the disk area for 4–5 minutes, then
use the brush provided and gently clean the disk. Do NOT scrub. Drain any excess diluted
vinegar and dry with a soft cloth.
You can use diluted vinegar and wipe the rest of the base of the humidifier. We do not suggest
running anything through the humidifier.
Why is there white dust on my furniture?
If water is especially hard or has a high mineral content, you may notice white dust around the
unit. White dust is not a problem it is from the minerals in the water that form the dust. The
humidifier evaporates the water and then the white dust is left in the unit, not sent out into the
air. If bothersome, use distilled water or you can purchase one of our Decalcification Filters
(FLTDC) to help with the problem.
