Frequently Asked Questions (FAQs) -- Humidifiers

Question: ***All Humidifiers***-How do I register for my warranty?
Answer: We no longer have product registration. The terms of your warranty have not changed in any way. Simply hold on to your receipt and if you require service in the future please give us a call or send us an email.
 
Question: All Humidifiers-How does my humidifier prevent/trap mold and bacteria?
Answer: Different types of humidifiers prevent bacteria/mold growth in different ways. Find your humidifier type below to read more about your unit.

Cool-Mist (evaporative)
The filter pad filters out mold, bacteria, algae and minerals from the water. Since the water enters the air by evaporating from the filter pad any impurities will be left behind in the pad and will not be released into the air.

Warm-Mist/Vaporizer
These types of humidifiers remove bacteria and algae during the boiling process. Any bacteria or algae present in the water will be killed by the temperature of the water. Any minerals will settle to the bottom of the base and will not be released into the air. Never add DuraFree (AC817) or any other solution to the water in these types of humidifiers to try to prevent mineral deposits in the humidifier. Doing so can be very dangerous as the chemical solution will be boiled and released into the air.

Impeller
An Impeller distributes droplets of water by forcing water up a shaft and out into the air. As a result, an Impeller type humidifier has no way of filtering impurities or killing bacteria.
 
Question: All Humidifiers-How does my humidifier produce moisture?
Answer: Different types of humidifiers produce moisture in different ways. Find your humidifier type below to read more about how your unit produces water.

Cool-Mist (evaporative)
A Cool-Mist humidifier works on the process of evaporation, only sped up through the use of a fan and filter. The filter pad "wicks", or soaks, up the water from the humidifier base. A fan runs above the filter pad causing the water to evaporate from the pad into the air. Therefore, a Cool-Mist humidifier run without a filter does not produce moisture.

Warm-Mist
A Warm-mist humidifier produces moisture by boiling a small amount of water and releasing steam into the air. The minerals are boiled off and will settle to the bottom of the base. Any bacteria or mold in the water will be killed by the temperature of the water.

Vaporizer
A Vaporizer produces moisture by heating small amounts of the minerals in the water using tiny electrodes in the shaft of the unit. The minerals then heat the water to a boil and release steam into the air. The minerals will then settle to the bottom of the tank, possibly becoming small black flakes. These flakes are normal and should be rinsed out when you refill the tank. Any bacteria or mold in the water will be killed by the temperature of the water.

Impeller
Impeller type humidifiers produce moisture by spinning a small shaft, called an impeller, which pulls water up and forces it out of the base through centrifugal force. This type of humidifier does not have any way of removing minerals from the water.
 
Question: All Humidifiers-How often should I clean my humidifier?
Answer: The unit should be rinsed daily and thoroughly cleaned according to the manual weekly. The unit should also be emptied if not in use and filter should be dried(If Applicable).
 
Question: All Humidifiers-My humidifier has a Humidistat feature. How do I set it and what does it do?
Answer: The Humidistat helps you keep a comfortable humidity level. The unit will cycle on and off to maintain this level once the Humidistat has been correctly set.
 
Question: All Humidifiers-What is the average desired humidity level for homes?
Answer: Most people are comfortable with a humidity level between 40-50%. Humidity levels above 60% can leave water marks on the walls and furniture. Turn your humidifier off if you start to notice condensation on your walls or furnishings. If you would like to know what the specific humidity level in your room is you can purchase a hygrometer from a local hardware store or home center.
 
Question: Cool Mist- How long should my Cool-Mist humidifier filter last?
Answer: The filter can last up to three months, depending on the water quality and how the filter is cared for. Remember, the less time a filter spends wet, the longer it will last, so be sure to take it out when not in use (where applicable)
 
Question: Cool Mist-Can I run my humidifier without the filter?
Answer: A Cool-Mist humidifier(evaporative type with wicking filter) run without the filter does not produce any moisture. Remember, a Cool-Mist humidifier works on the process of evaporation, only sped up through the use of a fan and filter. The filter pad "wicks", or soaks, up the water from the humidifier base. A fan runs above the filter pad causing the water to evaporate from the pad into the air. Without the filter, water will evaporate no faster than if you left a bucket of water on the table.

If using an ultrasonic type without the demineralizing filter, you may notice an increase in the amount of dust in your home, this is because the minerals in your water are being put out with the moisture.

If using an impeller type unit without the dynafilter in place, you may notice dust and other airborne particles getting trapped in your unit which will make the unit more difficult to clean.

We always recommend using filters in units that have filters.
 
Question: Cool Mist-How long do the filters last?
Answer: Filters will generally last 1-3 months depending on the usage, air and water quality.
 
Question: Vaporizer- After running my Vaporizer I notice a black deposit in the base. Is this normal?
Answer: This is completely normal. The black deposits are the heated minerals that have separated from the water during the boiling process. Simply rinse them out of the tank when you refill the unit.
 
Question: Warm Mist-Is my humidifier safe to use around children?
Answer: Caution should be taken when using a Warm-Mist or Vaporizer type unit around a child because the unit is boiling small amounts of water. Children should never be left unattended around the humidifier. Also, the cord should be out of reach of children to prevent them from pulling the Warm-Mist or Vaporizer humidifier down onto themselves

*Studies have shown that keeping indoor air at an RH level of 40-60% reduces survival of flu viruses compared to lower RH levels. When used as directed, humidifiers can achieve and maintain 40-60% RH levels.
