Minnesota-Specific Considerations
When choosing a filter in Minnesota, consider these local water quality factors:
- PFAS contamination: Especially important in the east metro near Woodbury, Oakdale, and Lake Elmo
- Hard water: Minnesota has naturally hard water; consider a filter that handles minerals or pair with a softener
- Agricultural runoff: Rural areas may have elevated nitrates from farming
- Older infrastructure: Homes built before 1986 may have lead plumbing
