Recommended Replacement Once Every 1 to 2 Months:
Filter discoloration is natural and will vary depending on water. Replace filter about every 1-2 months (depending on use and local water quality), or when performance starts to deteriorate. If you see that the filter has a heavy build-up of impurities or notice the presence of persistent odors associated with poor water quality, change the filter more frequently.

Humidifier Wick Filter Tip:
Extend the life of your humidifier wick filter with the ProTec Humidifier Cleaning Cartridge. Simply drop in the water tank for a fresh, clean mist and continuous protection against slimy build-up in your humidifier. Works in all cool wick-based humidifiers to prevent the growth of bacteria and extend filter life.
