Description

This is the correct replacement filter for these Honeywell Cool Moisture Humidifier models:

  • DH4C
  • DH831

The ideal indoor humidity level is 30-40%. Although levels can vary slightly depending on outdoor temperatures, this range seems to be most ideal in providing the greatest level of comfort by lessening the feeling of dry, itchy skin and irritated or inflammation of nasal passages and airways. You can easily monitor your humidity levels with a simple and inexpensive device called a hygrometer which you can find at your local home improvement stores.
