Whole House Water Filtration System for Well Water: A Complete Guide for New Hampshire Homeowners
If your home relies on a private well for water, you already know that with independence comes responsibility. Unlike municipal systems that are treated, tested, and regulated, well water is your responsibility alone. While well water often tastes better and lacks chlorine, it can also contain contaminants like arsenic, radon, iron, manganese, and even harmful “forever chemicals” like PFOA and PFOS. That is why many homeowners are investing in a whole house water filtration system for well water to ensure clean, safe, and great-tasting water at every tap.
At Advanced Radon Mitigation & Water Treatment, we specialize in designing and installing whole-home systems customized to address the unique water chemistry found in homes throughout Southern, Central, and Coastal New Hampshire. This guide explains why these systems are essential, how they work, and what options are available.
Why Well Water Needs Special Attention
In New Hampshire, more than 40 percent of households rely on private wells. These wells tap into underground aquifers, which may be exposed to both natural minerals and man-made contaminants.
Common Issues Found in Well Water:
- Radon in water – Odorless and radioactive gas released during showering or cooking
- Arsenic – Naturally occurring carcinogen common in granite-rich regions
- Iron and manganese – Cause staining, metallic taste, and appliance damage
- Hard water – Leads to scale buildup and reduces soap effectiveness
- PFOA and PFOS – PFAS “forever chemicals” linked to cancer and endocrine disruption
- Bacteria and coliform – Indicate contamination from surface runoff or septic systems
- Uranium – Another radioactive element found in New Hampshire groundwater
Without treatment, these contaminants can harm your health, damage plumbing and appliances, and reduce the overall value of your home.
What Is a Whole House Water Filtration System for Well Water?
A whole house water filtration system for well water is installed at the point where water enters your home, treating all of the water used for drinking, cooking, bathing, and cleaning. Unlike point-of-use systems that only treat water at a single faucet, whole-house systems ensure that every fixture in your home delivers safe and filtered water.
These systems are highly customizable. Depending on your water test results, you may require one or more stages of filtration to address different issues. For example, a home with high iron and radon levels would need different equipment than one with arsenic and PFOA concerns.
Benefits of Installing a Whole House Water Filtration System
1. Health and Safety
Filtered water is free from harmful contaminants like radon, arsenic, uranium, and bacteria. You and your family will enjoy safer water for drinking, showering, and cooking.
2. Appliance Protection
Hard minerals and sediment can wear down dishwashers, water heaters, and washing machines. Filtration systems reduce buildup and extend the life of your appliances.
3. Better Taste and Smell
Say goodbye to metallic or rotten-egg odors. Whole house filtration systems improve the overall quality, clarity, and taste of your water.
4. Cleaner Showers and Laundry
With soft, filtered water, your skin feels better after bathing, and your clothes stay brighter and cleaner.
5. Increased Home Value
A professionally installed water filtration system is a valuable feature that makes your home more appealing to future buyers.
Types of Whole House Filters for Well Water
At Advanced Radon Mitigation & Water Treatment, we recommend systems based on your home’s water chemistry. Below are the most common types of filters used in combination for whole house treatment.
1. Sediment Filters
Removes sand, silt, and debris that can clog fixtures and damage appliances. Often used as the first stage of treatment.
2. Iron and Manganese Filters
Specialized media filters eliminate orange and black staining and metallic taste caused by iron and manganese.
3. Radon in Water Aeration Systems
Aeration units remove radon gas by mixing water with air in a sealed chamber, then venting the gas outside. This is the safest and most effective method.
4. Arsenic Removal Systems
Use specific media to bind and remove arsenic from water. These systems are often paired with pre-filters for sediment or iron.
5. PFOA and PFOS Removal Systems
Granular activated carbon (GAC) filters or reverse osmosis (RO) systems are used to remove these harmful PFAS chemicals. For homes with high levels, a whole-house GAC system is recommended.
6. Water Softeners
Remove calcium and magnesium ions that cause hard water. Improves appliance efficiency and makes soap more effective.
7. UV Disinfection Systems
Kill bacteria, viruses, and other microorganisms using ultraviolet light. Ideal for wells with biological contamination risks.
8. pH Neutralizers
Correct acidic water, which can cause pipe corrosion and lead leaching. These systems raise the pH using calcite or magnesium oxide media.
Customizing Your Filtration System
Every well is different. That is why we never take a one-size-fits-all approach. We help you choose and combine systems based on:
- Water test results (we refer to certified labs for unbiased data)
- Flow rate requirements
- Household size and water usage
- Contaminant types and concentrations
- Budget and maintenance preferences
Once your lab results are in, we explain your options and install the ideal combination of systems to meet your home’s specific needs.
Installation and Maintenance
Installation
A typical system is installed where water enters your home, usually near the pressure tank. Our certified technicians complete most installations in one day with minimal disruption. All systems are tested and fine-tuned before we leave your property.
Maintenance
Maintenance needs vary depending on system type and water conditions. Most systems require periodic media replacement, filter changes, or backwashing. We offer service plans and reminders to keep your system running efficiently.
Frequently Asked Questions
Q: Do I need a whole house system if I only drink bottled water?
Yes. Even if you do not drink your tap water, you are still exposed to contaminants through showering, cooking, and brushing your teeth. A whole-house system ensures clean water at every point of use.
Q: How much does a whole house filtration system cost?
Costs vary based on the contaminants present, the size of your home, and the type of filters needed. We provide clear, up-front estimates based on your specific situation.
Q: Will the system change my water pressure?
Properly sized systems will not reduce your water pressure. We take flow rates into account when designing every installation.
Q: Do I need to test my water first?
Yes. Accurate, lab-certified water testing is essential. We can recommend reputable third-party labs to avoid any conflict of interest.
Q: What is the lifespan of the system?
With proper maintenance, most systems last 10 to 15 years or longer. Filter media and parts may need replacement every one to four years depending on usage and water quality.
