Dehumidifiers are essential for providing a comfortable and healthy indoor atmosphere as they eliminate moisture from the air. But if your dehumidifier suddenly stops collecting water, it can be quite frustrating, and you may not be sure about what exactly happened. Whether you’re trying to reduce high humidity in your home or protecting your possessions from mold and mildew, a malfunctioning dehumidifier can easily throw off the balance of your household. Fortunately, most of these problems can be fixed through some troubleshooting.
Understanding Your Dehumidifier
A dehumidifier operates by taking in humid air from a room, extracting the surplus moisture, and then pushing back dry air into the area. The air in the device goes through a cycle of passing over the cooling coils, where the moisture is turned into water and then collected in a tank or drained out through a hose. This procedure assists in lowering the humidity levels which, in turn, avoids the growth of fungi, mildew, and other issues associated with moisture in the house.
What is a Dehumidifier?
A dehumidifier is a powered appliance that has the purpose of decreasing and stabilizing the humidity level of the air, thus creating a more pleasant and safer indoor environment. It is typically employed in places with high humidity, like:
- Basements: Where moisture tends to accumulate
- Bathrooms: High-moisture environments
- Regions with moist climates: Areas prone to excessive humidity
Benefits of Dehumidifiers
Dehumidifiers not only lower air moisture content but also hinder the growth of mold, mildew, and dust mites, which are the main culprits of poor indoor air quality. High-end dehumidifiers usually feature adjustable humidity control, energy-efficient modes, and even smart sensors for effective moisture management.
How Does a Dehumidifier Collect Water?
Dehumidifiers obtain their water through a specific process:
- Air Intake: Humid air is pulled in with a fan
- Cooling Process: Air is cooled by blowing over cold coils or passing through an evaporator with refrigerant
- Condensation: Moisture in the air turns into liquid water
- Collection: Water either drips into an internal collection tank or is drained through a hose
💡 Desiccant vs. Refrigerant Dehumidifiers
Refrigerant Dehumidifiers: Use cooling coils to condense moisture
Desiccant Dehumidifiers: Absorb moisture through a special material, capturing water vapor directly from the air without any cooling involved
