Unboxing and Initial Impressions
The Music Nomad MN300 Humitar arrived in its compact packaging. The first thing I noticed was the small, highly absorbent sponge – quite different from a standard dish sponge. It's designed specifically for holding and releasing moisture to humidify your instrument. The included case is a nice touch for storage and portability.

The instructions emphasized using distilled water, but honestly, who constantly buys distilled water? Tap water can be used, but be aware that this could potentially lead to mold growth in the sponge over time.

Preparing the Humitar Sponge
Before placing the Humitar in your guitar case, the sponge needs proper preparation. You'll need to soak it in water until it's fully saturated. It’s important to avoid overly saturating the sponge – the instructions suggest squeezing out excess water before placing it inside the case. I used a small bucket to ensure easy handling.

The video suggests that gently massaging the sponge helps it absorb the water faster. Once soaked, the sponge is incredibly soft and supple, indicating it is ready for use.

Optimal Placement and Usage
The Humitar should not be placed directly between the guitar strings, as this could cause unnecessary stress and damage. Instead, the best placement is on the side of the instrument's sound hole, inside the hard case. This keeps the sponge away from the strings and prevents any potential damage

Alternatively, you can place the Humitar in any available open space within your guitar case. The goal is to maintain optimal humidity, typically between 40-55%, for your instrument.

Monitoring and Maintenance
Regularly check the sponge for dryness. If it feels hard, it needs more water. Aim to check the sponge weekly to ensure it's maintaining the proper humidity levels inside the case. Using a hard-shell case is crucial, as soft cases allow for faster moisture evaporation.

Using a hygrometer (humidity monitor) inside the case provides an even more precise way to control humidity and prevent over-humidification or under-humidification of your instrument.

Conclusion
The Music Nomad MN300 Humitar is a simple yet effective solution for maintaining the proper humidity level in your acoustic guitar or ukulele case. Its compact size and ease of use make it ideal for traveling musicians and everyday players. Remember to check and replenish the sponge regularly and always use a hard-shell case to keep it fresh. Though using tap water might lead to mold, the low price makes replacement relatively inexpensive.

Overall, the Music Nomad MN300 Humitar is a valuable addition to any guitarist’s or ukulele player’s arsenal for protecting their instrument from the damaging effects of dry air.
