This page covers types of products that help with humidity control in apartments. We focus on practical categories and what to look for, rather than specific brands—what's available varies by location, and products change over time.
Essential: Hygrometer
A hygrometer measures humidity levels. This is the most important purchase for anyone managing humidity because it removes guesswork.
Digital Hygrometer
Shows current humidity percentage. Basic models cost under $15. Look for ones that also show temperature. Some can track high/low readings.
Smart Hygrometer
Connects to your phone and tracks humidity over time. Useful for identifying patterns. More expensive but helpful for troubleshooting.
What to look for: Accuracy within 3-5% is typical for affordable units. Easy-to-read display. Some have mounting options for walls or shelves.
Passive Moisture Absorbers
These products absorb moisture without electricity. Good for closets, cabinets, and small enclosed spaces.
Calcium Chloride Absorbers
Crystals that absorb moisture and dissolve into liquid collected below. Disposable. Brand examples include DampRid. Effective for small spaces.
Rechargeable Desiccant Units
Contain silica gel or similar material. When saturated, you dry them in an oven or microwave to reuse. Better long-term value than disposables.
Silica Gel Packs
Small packets for drawers, boxes, and storage. Protect items in enclosed spaces. Buy bulk packs or save ones from product packaging.
What to look for: Match size to space—larger containers for bigger closets. Check coverage area ratings. Factor in replacement or recharging frequency.
Limitation: Passive absorbers work for small, enclosed spaces. They cannot dehumidify a whole room or apartment.
Portable Dehumidifiers
When passive methods aren't enough, dehumidifiers actively remove moisture from the air.
Mini Dehumidifiers
Small units for single rooms. Remove 10-20 ounces per day. Quiet, low power, affordable. Good for mild humidity in bedrooms or bathrooms.
Mid-Size Dehumidifiers
Remove 20-50 pints per day. Suitable for apartments up to 1,500 sq ft. Balance of effectiveness and energy use. Most common choice.
Large Capacity
50+ pints per day. For severe humidity or larger spaces. Higher energy consumption. May be overkill for most apartments.
Features to consider:
- Humidistat: Automatically turns on/off to maintain target humidity
- Auto shutoff: Stops when reservoir is full
- Continuous drain: Option to connect a hose for auto-draining
- Noise level: Check decibel ratings if using in bedrooms
- Energy Star: More efficient models save on electricity
- Portability: Wheels and handles for moving between rooms
Fans for Air Circulation
Fans don't remove humidity, but they improve air circulation, which helps moisture distribute rather than accumulate in stagnant areas.
Box Fans
Inexpensive, effective for moving air through windows. Can create cross-ventilation even with limited window placement.
Oscillating Fans
Distribute air across a wider area. Good for rooms without natural airflow. Tower styles are space-efficient.
USB/Small Fans
For closets or small enclosed areas. Low power, quiet. Helps prevent stagnant, humid air in tight spaces.
Bathroom Accessories
Products specifically helpful for the most humid room in your home.
Squeegee
Wipe down shower walls and doors after bathing. Removes water that would otherwise evaporate. Simple, effective, lasts for years.
Towel Warmer/Dryer
Heated racks dry towels faster, reducing how long they add humidity. Also keeps towels fresh between uses.
Bathroom Fan Timer
Replaces standard switch. Set fan to run for a specific time after showering. Ensures proper ventilation without remembering to turn it off.
Buying Considerations
Start Small
Begin with a hygrometer and basic moisture absorbers. See how much improvement you get from behavioral changes before investing in larger equipment.
Match Product to Problem
Closet humidity? Moisture absorbers. Bathroom humidity? Better fan use and a squeegee. Whole-apartment humidity despite good habits? Consider a dehumidifier.
Consider Ongoing Costs
Disposable absorbers need regular replacement. Dehumidifiers use electricity. Rechargeable desiccants cost more upfront but less over time. Factor in long-term costs.
Read Reviews
Before purchasing, check reviews from people in similar situations (apartments, specific humidity problems). Pay attention to reliability, noise levels, and actual effectiveness.
Renter Considerations
As a renter, focus on portable, non-permanent solutions. Avoid anything requiring installation or modification to the apartment. Everything listed here works without alterations.
