Storm & Humidity Surge Forecast 2025-2026: Why Is a Dehumidifier a Must-Have Device?

Storm Season Forecast 2025-2026 is Complex: Proactively Protect Your Assets with a Dehumidifier

According to the National Centre for Hydro-Meteorological Forecasting (NCHMF), the storm and rain situation in the 2025-2026 period is trending towards being more complex. The number of storms and tropical depressions in the East Sea is likely to be above average, bringing prolonged periods of heavy rain over large areas.

This warns of a more dangerous "enemy" that follows: periods of saturated humidity and severe dampness. When air humidity consistently stays above 80-90%, passive moisture control methods become nearly useless. This is when a proactive dehumidifier (also known as a moisture separator) becomes a must-have device to protect the health and property of both families and businesses.

1. What is a "Dehumidifier"? (Decoding the Term)

"Moisture Separator" and "Dehumidifier" are the Same

Many customers ask if a "moisture separator" is different from a "dehumidifier." In reality, they are two names for the same device. "Moisture separator" is a more technical term for a "dehumidifier". Both refer to a device that actively removes excess water vapor from the air using technology (like condensation or desiccant rotor).

Why Do We Need Proactive Dehumidification?

During storms or humid seasons, the outside air is often saturated (above 80-90% humidity). Traditional methods like mopping floors or using an air conditioner's "Dry" mode become passive, ineffective, and extremely costly in terms of energy. A dedicated dehumidifier is the only proactive solution that precisely controls humidity down to the safe, comfortable level (50-60%) you desire.

2. The "Devastating" Impact of High Humidity (Analyzing 2 Target Groups)

For Families (During Humid & Rainy Seasons)

  • Health: According to the U.S. EPA, high humidity is the perfect environment for mold, bacteria, and dust mites to thrive. These are primary triggers for respiratory illnesses (asthma, allergies), skin conditions, and are especially dangerous for children and the elderly.
  • Property: Slippery floors; clothes that won't dry and smell musty; electronics (TVs, cameras) that malfunction; leather and wood furniture that mildews and warps.

For Businesses (Warehouses, Factories)

  • Financial Loss: Goods (garments, agricultural products, paper) become moldy, clump, and lose quality.
  • Production Disruption: Machinery rusts, electronic components in the production line corrode, leading to malfunctions and inaccurate readings.
  • Loss of Reputation: Goods fail to meet export standards and shipment deadlines are missed.

Safe & Dangerous Humidity Levels

TOO DRY (< 40%RH)

Causes dry skin, chapped lips, and respiratory irritation.

IDEAL (40% - 60%RH)

Safe for health, protects equipment and furniture.

DANGEROUS (> 70%RH)

Mold and bacteria begin to grow rapidly, causing illness.

EXTREME DANGER (> 85%RH)

Saturated air, condensation on floors, high risk of short circuits.

6. Frequently Asked Questions (FAQ)

1. Are "moisture separators" and "dehumidifiers" different?

No. They are two names for the same device. "Moisture separator" is a more technical term that emphasizes the action of separating water vapor from the air.

2. Can I just use my AC's "Dry" mode instead of a dehumidifier?

It's not recommended. The "Dry" mode on an AC is only mildly effective when humidity isn't too high and it will also cool the room. During heavy rain or humid seasons (humidity >80%), the "Dry" mode is not powerful enough to cope and wastes a lot of electricity. A dedicated dehumidifier is much more powerful at removing moisture without over-cooling the room.

3. What is a safe humidity level for health and property?

The ideal and safest humidity level for both human health and protecting property is between 40% and 60%RH. Below 40% is too dry. Above 60%, rust accelerates, and above 70% is when mold begins to thrive.
