✅ What You Can Do About It
Test Your Home's Water Quality
A comprehensive home water test can reveal specific contaminant levels in your tap water, especially those from your plumbing, giving you precise data to address.
Install a Quality Shower Filter
Shower filters effectively reduce chlorine, chloramines, and disinfection byproducts, protecting your skin, hair, and lungs from their drying and irritating effects.
Shorten Shower Times and Improve Ventilation
Less exposure time to hot, steamy water reduces inhalation and absorption of volatile contaminants, while good ventilation minimizes their concentration in the air.
Moisturize Immediately After Showering
Applying a moisturizer to damp skin helps lock in hydration and creates a protective barrier against environmental stressors, counteracting the drying effects of tap water.
Consider a Whole-House Water Filtration System
For comprehensive protection beyond the shower, a whole-house system treats all water entering your home, addressing concerns for every tap and appliance.

Is Tulsa tap water safe to shower in?
While Tulsa's water meets federal safety standards for drinking, showering exposes you to contaminants differently. Volatile chemicals like chloramine and disinfection byproducts can be inhaled in steam and absorbed through the skin, potentially causing dryness, irritation, and respiratory concerns for sensitive individuals.
Does Tulsa have hard water?
Yes, Tulsa's water sources typically result in moderately hard to hard water, rich in minerals like calcium and magnesium. This contributes to soap scum, dry skin, dull hair, and mineral buildup on fixtures, which can be a common pain point for residents.
How do shower filters help with Tulsa's water?
Shower filters are designed to reduce specific contaminants common in Tulsa's water, such as chloramines and disinfection byproducts, which are known skin and respiratory irritants. They can also help reduce the impact of hard water minerals, leading to softer skin and hair.
What are disinfection byproducts and why are they a concern in my shower?
Disinfection byproducts (DBPs) like TTHMs and HAA5s form when disinfectants like chloramine react with organic matter in water. In the shower, hot water causes these chemicals to volatilize, meaning they turn into gas and can be inhaled, posing potential long-term health risks beyond skin absorption.
Will a shower filter help my eczema in Tulsa?
Many individuals with eczema find relief by using a shower filter, as it reduces irritants like chloramine that can strip natural skin oils and exacerbate flare-ups. While not a cure, minimizing these chemical exposures can significantly improve skin comfort and health for eczema sufferers.
