If although, you live in the desert and have had an acoustic for 10 years that hasn’t cracked, then you very likely won’t need a humidifier to protect it from cracking. You may be surprised though, what restoring a bit of moisture to the wood will do for the tone of the instrument.

If you store your instrument in its case this humidifier will be helpful. Submerse it in water for 5 minutes and wipe off excess, then store it in your case. Repeat twice a month. Works for guitars, violins, cellos, clarinets or any other fine wooden instrument.
