FAQ
Can moving to a new city cause skin or hair problems?
Yes — different cities have different water chemistry. Changes in chlorine levels, water hardness, or chloramine treatment can affect your skin and hair immediately after a move.
How do I find out what's in my city's tap water?
Check your city's annual Consumer Confidence Report (CCR), available from your local water utility. The EPA requires these reports to list contaminant levels.
Do shower filters work on hard water?
Standard carbon filters reduce chlorine effectively but have limited impact on hardness minerals. For hard water, look for filters with KDF media or consider a whole-house softener.
How quickly will I notice a difference with a shower filter?
Most people notice softer skin and less dryness within the first week. Hair texture improvements typically take 2-3 weeks as buildup gradually washes out.
