Why is water accumulating around my Guardian Humidifier?
Water accumulation around your Guardian Humidifier can occur due to several reasons. It might be caused by humidity saturation, in which case you should lower the mist control setting. Another cause can be that the unit is not level; if so, unplug it and place it on a level surface. Also, ensure you point the spray away from objects and raise the unit on a water-resistant level surface 2-3 feet off the floor.
How to fix low humidity level in Guardian H500?
A low humidity level in your Guardian Humidifier may be due to a dirty ultrasonic disk. Another reason might be that the water in the unit is too cold; replace it with cool, but not cold water. If the ultrasonic disk is damaged, contact Customer Service at 1.866.603.5900.
How to stop white dust forming from Guardian Humidifier?
If white dust is forming on nearby furniture when using your Guardian Humidifier, this may be due to hard water depositing dust. If this becomes a nuisance, use distilled water instead.
Why is my Guardian H500 not producing vapor?
If your Guardian Humidifier is not producing water vapor and humidity, try the following: * Unplug the power plug and then try again. * If there was a power failure, try again once the power is restored. * Ensure the tank is correctly attached. * Check that the mist outlet is in the upright position. * If the surface of the ultrasonic disk is dirty, clean it.
Why does my Guardian H500 smell bad?
A bad smell from your Guardian Humidifier is often due to poor maintenance or dirty water. Clean the product thoroughly.
What to do if Guardian Humidifier blows air but no vapor?
If your Guardian Humidifier blows air but does not produce water vapor, it could be due to excessive water; remove some water from the tank. If the desired humidity is lower than the current temperature, increase the desired humidity. Detergent residue or oil ingredients may be in the tank, so wash out the tank and try again. If you use hard water, replace it with softer water. Also, a dirty ultrasonic disk may be the cause; clean it.
Why is my Guardian H500 so noisy?
An increased noise level in your Guardian Humidifier could be because the unit is not placed on a flat, level, hard surface. Also, ensure it is NOT placed on a soft or absorbent surface.
Why is my Guardian Humidifier dripping when refilling?
If your Guardian Humidifier is dripping when refilling, it's likely due to water remaining on the bottom of the unit. Wipe the tank or tilt it to drain before transporting.
