The best choice depends on the roomโs measured humidityโnot a model ranking. Martin and Taylor both recommend keeping guitars at 45โ55% relative humidity (RH). If a digital hygrometer shows the guitar room persistently above that range, a room dehumidifier is a sensible category of solution; keep checking readings so you do not over-dry the space.
What humidity should a guitar room be?
Martin recommends 45โ55% RH for guitars, and Taylor identifies the same range as ideal. Taylorโs troubleshooting guidance gives 40โ60% RH as acceptable, a wider band that can help put a brief reading outside the ideal range in context. These are manufacturer care recommendations, not a universal diagnostic standard. Martinโs care FAQ and Taylorโs humidity guidance explain their targets.
Wood responds to moisture in the air. Taylor support author Glen Wolff explains, โWood is hydroscopic, meaning that it absorbs moisture from the air.โ Because room conditions can change, the useful goal is a stable range, not making the room as dry as possible.
Measure the room before buying a dehumidifier
Use a digital hygrometer that records minimum and maximum RH readings. Taylor recommends this approach to assess the guitarโs storage environment before deciding whether it needs humidification or dehumidification. A single spot reading may not show whether high humidity is persistent.

- Place the hygrometer in the area where the guitar is stored and check its readings over time.
- Compare the observed RH with the 45โ55% target. If readings repeatedly exceed that range, consider reducing room humidity.
- After changing conditions, continue monitoring. Adjust if the room falls below the target rather than assuming lower humidity is always better.
Room dehumidifier or case humidity control?
Choose a solution based on the space that needs control. Taylor recommends a room dehumidifier for a humid guitar storage area. For one guitar kept in its case, case-level two-way humidity packets address a smaller space. Taylor says its DโAddario Two-Way Humidification System is formulated to maintain 45โ50% RH; that is Taylorโs description of the product, not an independent test result. See Taylorโs guidance on using a guitar humidifier.

How to choose a room dehumidifier
The manufacturer care sources cited here recommend room dehumidification when a guitar storage area is humid, but they do not compare current dehumidifier models. They establish no best-performing model, capacity, noise level, energy use, drainage method, or price. Check current manufacturer specifications against your room and priorities before choosing.

- Noise: Consider operating noise if the guitar room is also a living or working space.
- Drainage and maintenance: Compare how water is collected or removed and what routine upkeep the model requires.
- Energy use: Review the manufacturerโs current energy information for the model you are considering.
Are guitar symptoms enough to diagnose high humidity?
No. Changes in a guitar can be clues, but Taylor cautions that action changes can have causes other than humidity. Check measured RH and seek a setup or service assessment if symptoms persist rather than relying on appearance or feel alone.
Taylorโs over-humidification guidance gives a high-humidity alert threshold of above 60% RH for at least 72 hours. That is Taylorโs troubleshooting threshold, not a universal diagnostic rule. Its articles on over-humidified guitars and dry-guitar symptoms describe signs to consider alongside measured conditions.
