Water Pitcher & Shower Filters: Drinking Water Guide

Water pitcher filters (Brita, PUR, ZeroWater) use activated carbon and ion-exchange resin to reduce chlorine taste, zinc, copper, and mercury. ZeroWater adds a 5-stage system that achieves near-zero TDS (Total Dissolved Solids), removing virtually all dissolved minerals. The tradeoff is faster filter depletion — ZeroWater filters last 2-3 weeks vs. Brita's 2 months.

Shower filters reduce chlorine and chloramine, which strip natural oils from skin and hair, causing dryness, irritation, and color-treated hair fading. Most shower filters use KDF (Kinetic Degradation Fluxion) media combined with activated carbon. They install in minutes between your shower arm and showerhead — no plumber needed.

For pitcher filters, the key spec is gallon capacity before replacement. Brita Standard filters handle 40 gallons (about 2 months for a household of two). Brita Longlast handles 120 gallons (6 months). PUR filters handle 40 gallons with superior lead reduction. Match the filter type to your household's daily water consumption.
