How Much Do Home Water Filtration Systems Cost?

Whole House Water Filtration System Cost

The average cost to have a water treatment & purification system is $2,013, although some homeowners might pay anywhere between $992 and $3,076, depending on a variety of factors.

Whole House Water Filter Installation Cost

Whole house water filter installations costs $600 to $4,200. Commercial grade systems run $5,000 to $14,000 to purchase and install. Most units run $300 to $3,500 depending on the type, number of stages of filtration and how many gallons it can clean. Labor and materials add another $300 to $700.

These get placed near where the water enters the house, also known as the Point-of-Entry (POE). Sometimes you’ll see this type referred to as a POE system. Popular brands such as Pelican, Aquasana, and CuZn all provide homeowners with different levels of filtration to tackle problems like chlorine, bacteria, fluoride and more.

Multistage filtration systems have multiple filters, in order of installation:

1. Sediment filter: Removes suspended solids.

2. Carbon filter: Removes chlorine to help protect the RO filter. Improves taste.

3. Reverse osmosis membrane: Removes compounds and drastically reduces total dissolved solid impurities

4. Deionization filter: Removes most remaining dissolved solids.

5. UV light: Final step in systems equipped with it to sterilize the water of any left-over living organisms.

Well Water Filtration System Cost

Well water filtration systems cost the same as any whole house treatment, or $1,000 to $4,000+. However, they’re much more specialized depending on any issues with each well. For example, one well might have a lot of sediment, but otherwise is fine to drink while another is crystal clear but has bacteria or heavy metals.

Reverse Osmosis Systems

Reverse osmosis systems cost $250 to $4,000. Most people choose under sink, faucet-based reverse osmosis systems, which cost $250 to $1,300. General whole house types run in the $1,000 to $4,000 range. Reverse osmosis systems require regular filter changes to operate effectively, adding to the cost of such a system over time.

Under Sink Water Filter Installation Cost

Under sink water filter installation costs $150 to $1,200. For a DIY install, systems alone cost $50 to $1,000. Installation usually runs $100 to $300 for a professional. Popular brands like Aquasana, Culligan and Aqua Pure can cost $100 or less at local home improvement stores or plumbing centers.

Single tap filters are a popular option for homeowners who want to filter for drinking and cooking but aren’t concerned about showers, laundry or dishwashers.

Water Purifying Machine Prices

UV Light Water Treatment Cost

UV light water treatment costs $500 to $1,500 or more. It’s designed to use with other treatment system installations, not as a standalone product. It only neutralizes living organisms, like bacteria and leaves chemicals and heavy metals in. Ultraviolet light works best in clear water, meaning you should filter impurities prior to UV sterilization.

Water Distiller Prices

Priced between $150 and $1,500 or more for home use and depending on capacity, distillers make good options for people who simply want clean-tasting drinking and cooking water. Commercial grade machines can hit $5,000.

This is one of the best ways to get rid of contaminants such as heavy metals, fluoride and bacteria. Distillers don’t remove all the chemicals but does rid it of minerals and dangerous heavy metals.

Chemical Injector Water Purification Cost

Chemical injectors for chlorine purification cost $600 to $1,500 to install. They inject chlorine and optional dyes to purify your rainwater or well water. With other methods that remove chemicals priced competitively to this method, it’s not often used.

Rainwater Filtration System Cost

Complete rainwater post collection filtration systems cost $200 to $10,000+ depending on the size of the system and what components you need. Complete collection and filtration systems, including storage plus pre and post collection filtration, run $1,000 to $30,000+ for most homes.

Since rain comes in a purified, drinkable form, the largest price comes from collecting and storing it. In some cases, it can pick up airborne pollution, but it’s minimal. Most often, you only need a simple filtering device. Most of the contamination from rainwater comes from the collection process, where it picks up debris like sand, dirt and other pollutants.

A typical system uses these stages:

• Rain collection: varies. Gutters and downspouts cost $500 - $1,500 or more. This uses gutters and pipe systems to collect runoff from roofs.

• Prefilters: $150 - $500. This filters out debris, such as sand They include preflush, downspout diverters, in ground and in tank. They pull out large debris, such as leaves, sand and gravel.

• Storage: $500 - $20,000. Depending on rainfall and how much water you’ll need, you’ll have to invest in a storage container. While not technically part of the filtration system, it’s necessary to maintain a consistent supply of water. You can purchase rooftop, above ground, in-home or underground reservoirs to meet every home configuration.

• Filtration: $1,000 - $4,000. A typical reverse osmosis system gets used here, sometimes with a chemical or dye injector.

Water Purifier Price Factors

• Size of the system. How much do you need filtered? Drinking water means you probably only need one or two point-of-service (or point of use) units installed under a sink. For adding showers and laundry, you’ll want a whole home system.

• Number of stages. The more stages you get, the higher the price. You can get anything from a 2 stage under sink mount for $50 while a commercial grade 10 stage system might run $5,000 or more.

DIY Water Filter Installation vs. Hire a Pro

You’ll find plenty of DIY install kits for point of use installations. It usually involves screwing a couple connections onto your sink pipes. You can also opt to have a pro install these as well. Most whole home models need professional installation since they connect directly to your homes plumbing.

The best way to make sure your system works properly is to hire a local water filtration professional. They’ll not only be able to make sure it gets in correctly, but they’ll also walk you through your options and what they think makes the most sense for your home.
