Factors in Calculating Home Water Filtration System Cost
There are hundreds of variables at play when choosing a home water filter. Each one has a different effect on how much it will cost for a water filtration system. From system type to size to brand, here are several of the main factors to consider when determining the cost of a home water filtration system.
System Type
The most significant factor for home water filtration system cost is the type of system the homeowner chooses. Filtration unit costs will range from $50 to $9,000, depending on the type the homeowner chooses. On the less expensive side, carbon filters cost between $50 and $500, and ultraviolet light units cost between $200 and $1,000. On the more expensive side, the average cost of a whole-house water filtration system like well-water filters and reverse osmosis units can range from $250 to $4,000 and up. Other types of water filtration systems, like ionization and chemical injectors, fall in the middle of the range.
System Complexity
Generally speaking, the more complex a water filtration system is, the more it will cost. The increased cost is due to how much more difficult a complex unit is to build, install, and maintain. Complex water filtration systems have more working parts and intricacies. The complexity of the system and the costs associated with it are important to keep in mind for initial installation and future maintenance tasks, as simple systems also cost less to maintain than more complex ones, saving money over the long run.
System Size
Water filtration systems are often categorized as either whole-house or individual units. Individual, also called point-of-use, units can be installed under-sink, on a countertop, on a faucet, or in a pitcher. A whole-house system will generally cost at least $1,000, while an individual unit could be as little as $150. The best whole-house water filters treat water as soon as it enters a home and are usually larger in size. They can cost from $1,000 to $4,200 or even more. Point-of-use units treat water at a single source, like a sink or faucet, and cost from $150 to $1,200.
System Brand
As with cars and appliances, the cost of a home filtration system depends on the product’s brand. Certain brands are more high-end, offering superior quality and more features, whereas others are more entry-level, compromising a bit on quality to allow a more affordable price. The cost of an entry-level home water filtration system runs between $750 and $3,000, while a high-end unit costs $4,000 to $8,000. Trusted household brands typically offer better customer service and more inclusive warranties, hence the higher price point. Here are some common brands and their average price ranges for the system only:
- Culligan Water: $80 to $6,000
- Kinetico Water Systems: $500 to $5,000
- Ecowater Systems: $750 to $3000
- Aquasana: $800 to $5,000
- Water Boy Systems: $900 to $5,000
- RainSoft: $4,000 to $8,000
Number of Filters
Depending on the composition of the home’s water, more than one filtration system might be needed to achieve the desired purification. For example, if the main water source is highly contaminated or the pipes and systems in a home are older, two or three filtration systems may be needed for the best results. Multistage filtration units are more expensive than single-stage, as more parts are required for the process.
Filtration Rating
A water filtration unit needs to be sized based on the home’s water consumption. Size options are based on a filtration rating or flow rate measured in gallons per minute. Homeowners can work with a water treatment professional to determine the filtration rating their system requires based on peak water flow. The higher the filtration rating needed, the higher the cost of the complete water filtration system.
Installation Location
Whole-house water filtration systems are typically installed near the main water shutoff inside a home’s basement. The level of difficulty in accessing this location will affect the total cost for whole-house water filtration systems. For example, an installer might charge extra labor costs or need to work more hours when the main water line is only accessible from a tight location or beneath a crawl space. If the installation location is easily accessible, the cost for installation will generally be lower.
Labor
The labor costs associated with water filtration system installation will likely add $300 to $500 on top of material prices. Labor pricing is usually lumped into the overall water filtration system cost and not separated out, so it might not be clear to homeowners the exact amount they are spending on labor. A water filtration system can usually be installed in just 1 day. Installing a whole-house system will take much longer than installing an individual filtration unit.

Permits
Homeowners may be required to get a permit when installing a whole-house water filtration unit. They can check with their local building department to determine whether a permit is needed. If so, homeowners can expect to pay between $100 and $600 for the permitting process. Installing a whole-house system requires connecting to a home’s main water line, which typically requires an inspection by a building official to make sure everything is up to code. Homeowners who choose to move forward with a project without a permit when one is needed could face future issues like difficulty selling the home or being forced to remove the water filtration system entirely.
Geographic Location
Geographic location can affect the cost of a water treatment system for home use in two ways. First, the price of materials and labor fluctuates from place to place. Materials and labor tend to cost more in dense urban locations with more demand and a higher cost of living than in rural locations where the cost of living tends to be lower. Secondly, water composition will vary depending on where the home is located, affecting the filtration system cost. Some areas might require specific types of filtration due to the local water contaminants, especially if the water is from a well and isn’t initially treated at a water treatment plant.
Additional Costs and Considerations
In addition to the above factors that affect home filtration system cost, the following charges might also apply. Homeowners will want to consider how water testing, additional plumbing, and maintenance costs will impact their budget when it comes to their water filter installation project.
Water Testing
Before choosing which type of water filtration system to use, it is often recommended for homeowners to have the water supply tested. The price of water testing ranges from $30 to $500. To keep costs on the lower end, homeowners can purchase a water testing kit from a local home improvement store or through their local municipality. Alternatively, they can hire a professional to complete the test to ensure the results are accurate and comprehensive.
Additional Plumbing
Additional plumbing may be required to install a home water filtration system properly. This factor can come into play if the existing plumbing line does not have a proper location to attach the filter’s piping or if the current plumbing configuration needs to be altered. A plumber will generally charge between $45 and $200 per hour for this additional plumbing work, along with the cost of materials.
Maintenance Costs
After installation is complete, homeowners can expect to pay annual maintenance costs to keep their filtration system in good working order. Water filtration system maintenance costs will range from $50 to $300 per year. These costs include swapping out filters and the replacement of worn-out parts. Maintenance costs for multistage or whole-house filtration systems will be more expensive than for single-stage or individual units.
Types of Home Water Filtration Systems
The cost of a whole-house water filtration system depends almost exclusively on the type of system used. In some cases, a house might require more than one type of system to meet the filtration needs.
Reverse Osmosis
One of the most popular types of systems, reverse osmosis home water filtration systems cost between $250 and $4,000. Smaller reverse osmosis systems placed under a sink or on a faucet may cost as little as $250 to $1,300. Whole-house reverse osmosis systems are more expensive at $1,000 to $4,000. This type of filter sends water through a membrane under pressure to remove harmful chemicals and bacteria. The liquid is then stored inside a pressurized tank for future consumption. Reverse osmosis systems cannot remove volatile organic compounds (VOCs), chlorine, pesticides, or solvents from water; therefore, additional filtration units may be necessary. It is important to note that this process produces a fair amount of wastewater as the removed chemicals are washed away and discarded.
Well-Water Filter
For houses with wells, a well-water filter costs anywhere from $1,000 to $4,000. Well-water filtration systems are built to address the specific mineral composition in the water, so the price will fluctuate based on that. The variation in contaminants depends on the physical location of the well and its surface depth—deep wells are typically exposed to a wider variety of sediment, bacteria, and minerals than shallow ones. Some of the best well-water filtration systems are multistage, meaning more than one type of filter is used to remove impurities from the water.
Carbon Filter
A carbon filter house water filtration system cost ranges from $50 to $500. Carbon filters remove chlorine from water, improving taste and smell. Water travels through activated carbon, which is positively charged, and sediments and chemicals that negatively impact taste are removed. Carbon filters come in various forms, such as carbon gravel which is less expensive than carbon blocks. Carbon gravel is made from everyday organic materials, like oats and coconut shells. Carbon blocks take the form of a cartridge and are regularly swapped out. Both forms can be installed on a water tap or a whole-house system and are relatively easy to install and maintain.

Ionization
Ionization home water filtration systems cost between $1,000 and $2,000. These systems use low-frequency electromagnetic pulses to reverse the charge of minerals in drinking water. The water is pulsed thousands of times per second to ionize the source of contaminants. Ionization filters can produce two different types of water: alkaline and acidic. Alkaline water is a superior drinking water that tastes slightly different than tap water. Keep in mind, using alkaline water for coffee or tea might alter the taste. Acidic water is best used for cleaning purposes.
Ultraviolet
Another type of home water filtration system that uses electricity is an ultraviolet system, which ranges in cost from $500 to $1,500. UV light water treatment systems use ultraviolet light to kill harmful bacteria as water runs through the unit. These are usually whole-house systems that treat water as it enters the home. Ultraviolet systems cannot be used on their own for water filtration, as they only neutralize living organisms like bacteria that cause digestive issues. Instead, a UV treatment system should be used alongside another type of water filter that treats sediments and minerals. Ultraviolet filtration units tend to be larger than most filters, but they are still smaller than reverse osmosis or water softening systems.
Chemical Injector
A chemical injector water treatment system costs anywhere from $300 to $1,000 for the unit alone. Labor installation costs will likely add another $300 to $500. Chemical injector systems inject small quantities of chemicals into well water or rainwater to purify it. These chemicals are usually hydrogen peroxide or chlorine.
Water Distiller
The cost of a water distiller filtration system ranges from $50 to $4,000 for the unit, plus an additional $300 to $500 for the installation labor. A water distiller boils the water entering a home. The water vapor created is then collected, cooled, and used as clean drinking water—this process of boiling and condensing the water leaves behind all of the pollutants and contaminants. Water distillers are usually smaller countertop units. It takes about 4 to 6 hours to produce a gallon of distilled water, so most units run automatically to keep up with demand.
Water Softener
Water softening systems cost anywhere from $500 to $6,000, with an average water softener system cost of $1,500. Water softeners are used to treat hard water. Hard water can cause problems due to a high mineral content, such as buildup on pipes that damages appliances over time. Water softeners can be magnetic, electronic, descaler, or ion exchange—each type works to remove and collect the excessive minerals in hard water. Some of the signs a home needs a water softener include water stains, scale buildup, faded laundry, increased utility bills, and more. A water softener is usually installed alongside another type of filtration unit.
Do I Need a Home Water Filtration System?
While a home water filtration system can benefit any homeowner, there are a few telltale signs that water treatment is more of a need than a want. Homeowners should consider these signs they need to filter their water as detailed below.
Bad-Tasting or Smelly Water
Having water that tastes or smells bad is often the main reason homeowners choose to install a filtration system. Poor-tasting water can be difficult to consume and makes beverages like coffee and tea taste strange. A carbon filter installed on a sink faucet or a whole-house filtration system will remove the contaminants, such as chlorine and minerals, that cause this bad taste and smell.
Home Uses Well Water
Well water is not necessarily a bad thing—it just isn’t treated the same way municipal water is. Water from a private well usually contains heavy metals and other contaminants. It can even be exposed to pe
