What the Refrigerator Humidity Controls Actually Do.
Why Refrigerator Humidity Controls Matter
Refrigerator humidity controls are designed to regulate moisture levels inside crisper drawers. Using the wrong setting can cause food to spoil faster, wilt, or develop excess moisture. When set correctly, humidity controls help maintain freshness, reduce food waste, and support proper airflow inside the refrigerator.
Understanding how these controls work allows homeowners to store food more effectively and avoid unnecessary strain on the appliance.
How Refrigerator Humidity Controls Work
Most refrigerators include at least one crisper drawer with a humidity control slider labeled High or Low. This control adjusts airflow within the drawer.
High humidity closes the vent, trapping moisture inside
Low humidity opens the vent, allowing moisture and gases to escape
These settings help create the ideal environment for different types of food.
When to Use High Humidity
High humidity settings are best for foods that tend to lose moisture quickly. Trapping moisture helps prevent drying and wilting.
Foods commonly stored on high humidity include:
Leafy greens
Lettuce
Spinach
Broccoli
Carrots
Fresh herbs
These items stay crisp longer when moisture loss is minimized.
When to Use Low Humidity
Low humidity settings work best for foods that naturally release moisture and gases as they ripen. Allowing airflow helps prevent premature spoilage.
Foods commonly stored on low humidity include:
Apples
Berries
Grapes
Peaches
Pears
Using low humidity helps control excess moisture and slows decay.
Common Mistakes With Humidity Controls
Many homeowners overlook humidity settings or store mixed foods in the same drawer. Common issues include:
Using the same setting for all foods
Overfilling drawers, which restricts airflow
Storing fruits and vegetables together when they require different humidity levels
These habits can reduce food freshness and create unnecessary moisture buildup.
Tips for Using Refrigerator Humidity Drawers Effectively
Match the humidity setting to the food type
Avoid overpacking drawers
Clean drawers regularly to prevent moisture buildup
Keep refrigerator temperatures consistent
Check seals and vents for proper airflow
Small adjustments can make a noticeable difference in food longevity.
