  • Optional 6 GPM UV Water Sterilizer add-on

Determining Whole House Water Filter Size

If you have a high level of contaminants or a larger number of residences, you should consider a larger unit that offers more media for more contact time. We have provided a basic suggestion but keep in mind the contaminant level. If you would like to speak to a member of our team to discuss your specific water needs, please call us.
