Common Issues With Your Humidifier

October 05, 2023

Humidifiers provide relief during dry winter months by adding moisture to the air. Extra moisture in the air helps alleviate common winter issues like chapped skin, irritated eyes, allergies, and sinus headaches. However, the humidifier can stop working due to the following issues.

Clogged Orifice

The orifice is typically a small opening or nozzle that controls water flow into the humidifier's distribution system. When it becomes clogged, it restricts or even completely blocks the water flow. This can result in reduced or no moisture being released into the air.

A clogged orifice will lead to a decrease in the humidifier's efficiency. As a result, the humidity level in the room may remain lower than desired. A lower humidity level can lead to discomfort, especially during dry seasons or in climates with low humidity. 

In some cases, if the orifice remains clogged for an extended period, it can lead to increased pressure within the water supply system of the humidifier. This elevated pressure can cause damage to the device over time.

Using distilled water in your humidifier can help reduce mineral buildup and scale that can clog the orifice over time. Also, periodically descale your humidifier to remove mineral deposits and clear the orifice. You can use a vinegar and water solution or a commercial descaling product.

Dirty Water

If the water in the humidifier's tank is dirty or contaminated, it can enter the air as a fine mist along with the water vapor. This can happen if you don't regularly sanitize and clean the tank. Bacteria, mold, and other microorganisms can grow in the stagnant water, releasing these contaminants into the air when the humidifier is in use.

Many humidifiers use filters to trap impurities and minerals in the water before it is released into the air. If these filters are not replaced or cleaned regularly, they can become clogged with contaminants, allowing dirty water to pass through and be dispersed into the air. 

Also, suppose you fill your humidifier's tank with tap water that contains a high level of minerals or impurities. In that case, these substances can be released into the air as the water evaporates. This can lead to white dust or mineral deposits on surfaces in your home, and in some cases, it can affect indoor air quality.

Clean the humidifier's tank, water reservoir, and any removable parts according to the manufacturer's instructions. This typically involves using a mild detergent and warm water to clean and disinfect these components.

Lack of Steam or Mist

A humidifier may not produce steam or mist even when it turns on as it normally should. Check if the water tank is filled to the recommended level. 

The water quality you use can also affect the humidifier's performance. If your water is hard or has a high mineral content, it can lead to mineral deposits in the humidifier, clogging the nebulizer or ultrasonic element. Using distilled or demineralized water can help prevent this issue.

Additionally, mineral deposits, mold, or bacteria can build up in the humidifier over time, blocking the mist output. Regularly clean and maintain your humidifier according to the manufacturer's instructions.

Bad Odor

A bad odor coming from a humidifier can be unpleasant and concerning. One of the most common causes of unpleasant odors in a humidifier is bacteria or mold growth within the unit. Humidifiers create a moist environment that is conducive to developing these microorganisms, especially if the water used is not clean or if the unit is not properly maintained. The bacteria and mold can release foul-smelling compounds into the air.

Regularly clean the humidifier following the manufacturer's instructions. This includes cleaning the water tank, base, and any removable components.
