Additionally, whole-house water filtration systems can help to improve the lifespan of appliances and plumbing, and even reduce the need for bottled water.
By investing in a water filtration system, homeowners can enjoy softer skin, healthier hair, and an overall better water experience. The convenience of having filtered water available throughout the home cannot be overstated, making daily activities like cooking, showering, and drinking more enjoyable and safer.
Understanding Your City Water: Start With Testing
Review Your Consumer Confidence Report (CCR)
Your local utility publishes a Consumer Confidence Report (CCR) every year. This document provides a detailed breakdown of the contaminants found in your water. Reading your CCR is essential before choosing a filtration system.
Consider At-Home Water Testing Kits
In addition to reviewing your CCR, it’s often a good idea to test your tap water using an at-home kit. These kits detect contaminants that might not appear in utility reports or accumulate between testing intervals.
Key City Water Contaminants to Remove
Chlorine and Chloramine
Chlorine and chloramine, common disinfectants used in municipal water supplies, can affect water taste and pose health risks over long-term exposure.
Heavy Metals (Lead, Iron, etc.)
Aging infrastructure can contribute to lead and iron contamination in your water. These are particularly hazardous and should be removed with a system tailored to metal removal.
PFAS (Forever Chemicals)
Some regions report high levels of PFAS, synthetic chemicals linked to adverse health effects. These are more difficult to remove and require advanced filtration systems.
Salts and Minerals
Excess calcium and magnesium can cause scaling in hard water areas and reduce appliance longevity.
Types of House Water Filters
Several types of house water filters are available, including whole-house water filters, under-sink filtration systems, and countertop filters. Whole-house water filters are installed at the main water line and provide filtered water to the entire home, ensuring that every faucet and appliance receives clean water.
Under-sink filtration systems are designed to filter water at specific faucets, making them ideal for drinking and cooking purposes. Countertop filters are portable and easy to install, providing a convenient solution for renters or those who need filtered water in specific areas.
Each type of filter has its own unique benefits and advantages, and the right choice will depend on the homeowner's specific needs and preferences.
Best Whole House Filter Systems for Chemical Removal
Activated Carbon Filtration with Catalytic Coconut Shell Carbon
For general chemical contaminants like chlorine, chloramine, pesticides, and some PFAS, whole-house activated carbon systems using catalytic coconut shell carbon offer excellent performance.
Benefits of Catalytic Carbon
- Removes a broader range of contaminants than standard carbon
- Particularly effective against chloramines
- Long filter life and high flow rate
When to Add a Water Softener or Conditioner
- Traditional Salt-Based Water Softeners: If you struggle with hard water, a salt-based softener helps by replacing calcium and magnesium ions with sodium.
- Salt-Free Water Conditioners: Ideal for homeowners who want scale prevention without sodium. These systems crystallize minerals instead of removing them.
Why Reverse Osmosis (RO) is Ideal for Drinking
An undersink or countertop RO system is one of the most effective ways to purify drinking water. It removes:
- Heavy metals
- Fluoride
- PFAS
- Nitrates
Combining RO with a Whole House System
For optimal results, use a whole-house catalytic carbon system for bathing and washing, then add an under-sink RO system for clean, filtered drinking and cooking water.
Eco-Friendly Options for House Water Filter Systems
Several house water filter systems are designed to be environmentally friendly. These systems use natural filtration methods, such as activated carbon or UV light, to remove contaminants and impurities from the water. Additionally, many whole-house water filtration systems are designed to be low-maintenance and energy-efficient, making them a great choice for homeowners who want to reduce their environmental impact.
By choosing an eco-friendly house water filter system, homeowners can enjoy clean and filtered water while also doing their part for the environment. These systems provide high-quality water and contribute to a sustainable lifestyle.
Health Benefits of Clean Water from a Filtration System
The health benefits of clean water from a filtration system are numerous. By removing harmful contaminants and impurities from the water, whole-house water filtration systems can help reduce the risk of waterborne illnesses and improve overall health and well-being. Clean water can also help to improve the taste and quality of food and drinks, and even reduce the risk of certain health problems, such as skin and hair issues.
Additionally, whole-house water filtration systems can help to remove harsh chemicals and contaminants that can damage skin and hair, leaving homeowners with softer skin and healthier hair. By investing in a water filtration system, homeowners can enjoy a healthier and happier lifestyle, with the peace of mind that comes from knowing their water is safe and clean.
How to Choose the Right Household Water Filter System
Base Your Choice on Water Chemistry
No single system works best for all situations. For example:
- If you have high chlorine or chloramines, go with catalytic carbon
- High hardness over 12 grains per gallon: consider a salt-efficient water softener
- Moderate hardness up to 12 grains per gallon: consider a no-salt water conditioner.
- PFAS: ensure your system includes advanced filtration like RO or activated carbon
- Are you concerned about boil orders or city-wide contamination with bacteria? Use an ultraviolet sterilizer with a nano-ceramic bacteria cyst filter.
Consider Maintenance and Filter Replacement Costs
Check how often the filters need replacing, the cost of replacement parts, and the unit's overall lifespan.
Professional Consultation and DIY Installation
Work with a water treatment expert to ensure your system is sized and installed correctly based on flow rates and household needs. If you have basic plumbing skills, consider installing yourself or hiring a handyman or plumber.
Common Questions About City Water
Is it Common for City Water to Contain Contaminants?
City water often contains trace contaminants, even when it meets federal safety standards. Some of the most common include:
- Chlorine or chloramine (used for disinfection)
- Trihalomethanes (disinfection byproducts)
- Lead (from plumbing)
- Nitrates (from agricultural runoff)
- PFAS (“forever chemicals”)
Does City Water Contain Chlorine?
Yes, most city water is disinfected with chlorine to kill bacteria and other pathogens before it reaches your home. While effective and inexpensive, chlorine can leave a noticeable taste or smell and form regulated disinfection byproducts (DBPs).
What are Chloramines, and are They Safe?
Chloramines are a combination of chlorine and ammonia used by some cities as an alternative disinfectant. They are more stable than chlorine, maintain disinfection longer, and produce fewer DBPs, but are harder to remove. Specialized filters like catalytic carbon are needed. Chloramines may irritate sensitive individuals and are toxic to fish.
What Does “Parts Per Million” or “Parts Per Billion” Mean?
These units describe contaminant concentration. 1 part per million (ppm) is one drop in 13 gallons of water; 1 part per billion (ppb) is one drop in an Olympic-size pool. Understanding this puts contamination levels in perspective.
What are Disinfection Byproducts, and are They Harmful?
DBPs are formed when disinfectants like chlorine react with organic matter. Common examples include trihalomethanes (THMs) and haloacetic acids (HAAs). They are linked to bladder cancer and reproductive issues. Utilities monitor DBPs, but many homeowners use carbon filters to reduce them further.
How Can I Tell If My Water Has Lead in It?
The CCR provides average lead levels from sample homes, but only testing your tap water confirms your household's risk. Lead usually enters through old plumbing rather than the municipal supply. We recommend using a certified kit or sending a sample to a lab.
What If My City Water Report Shows a Violation?
Utilities must notify you of violations and corrective actions. Violations can stem from:
- Exceeding contaminant limits
- Missing tests
- Treatment process failures
