Mold is developing in drainage tubing - how do I prevent?

The manufacturer states you can use tap water in these devices, but then goes on the disclaim that if you have water with minerals or hard water then white "dust" deposits can occur. Theses deposits are supposed to be noted and if seem, you are to change to filtered or distilled water or purchase one of their filter cartridges. These devices use very tiny holes to produce the mist you get out of them. It takes almost nothing to clog them. You should always use distilled water in these devices to prevent clogging. They also require very regular cleaning to stay clean and thus prevent them from becoming mold fountains. White vinegar and water should be used for cleaning. Avoid detergents as they can gum up the inner workings of the unit.

You can purchase the tubing at most hardware stores or any HVAC supply store. They carry the vinyl plastic tubing and pvc pipe for drain lines.

One way of removing the gunk is to disconnect the tubing from the humidifier and use a flexible and thin rod that will fit in the tubing and try to dislodge it, or you can try using a shop vac and see if the suction pressure will remove it. If the tubing is really clogged then sometimes it's better to just replace the vinyl tubing with pvc pipe and drain it to the floor drain, I always prever pvc pipe over vinyl tubing when it comes to drain lines for humidifiers.

Mold and algea form in the tray and filter of drum style humidifiers because humidifiers are a warm damp place, perfect breeding grounds! I suggest updating to a drain through style humdifier, as it does not allow water to sit stagnent in a tray. Hope this helps

Use Citric acid mixed with hot water to remove the mold, it is found in the cooking Isle of most shopping center, EG Woolworths, IGA ect ect

i cant see why not. just make sure you have good ventilation to prevent mildew or mold growth

just replace the hose. its 1/2 vinyl tubing you can get the required length at any hardware store and a hose clamp to support to bottom of he humidifier

A small discharge of water coming out of the bottom of an April Aire drain spud is normal. This feature constantly tries to rinse the system. This helps to prevent the possibility of mold or bacteria accumulating in the unit from standing water. It may appear to be alot of water. But be reassured that you are breathing in cleaner air. Now if it continues to drain constantly even when it is turned off then you should repair the unit.

Most modern humidifiers use a constant drain to flush mineral deposits, and to keep the water fresh at all times. This keeps the unit from holding standing water. This keep the water fresh and prevents mold spores from infesting the air in your home.

Features: Low Maintenance:
* Regulated Release ™ System - eliminates stagnant water while preventing mineral build-up on the wick or filter, which can impede performance in ordinary evaporative humidifiers.
* Dishwasher-Safe, Easy-Clean Base and Tank - with antimicrobial agents molded into plastic parts to inhibit the growth of microorganisms.
* PermaWick ™ - permanent wick never needs to be replaced, saving up to $45 per year in replacement filter costs.
* Top Down Water Dispersion - evenly disperses water from the top over the entire wick to prevent mineral build up that can impede performance.
