Whole House Water Filters:  Frequently Asked Questions

We get a lot of questions from people about Whole House Filters. Because Hydroviv has a “Help No Matter What” mindset when it comes to technical support, we sometimes find ourselves helping our website's visitors evaluate products that we don’t sell!

Update:  August 8, 2017:  After over a year of R&D, we are thrilled to announce that we have launched a purpose-built whole house water filter to remove rotten egg smell from all of the water that enters your home!

What Is a Whole House Water Filter?

As the name suggests, whole house filters are installed on a home’s main water supply, so they process all water that comes into the house, including water used to flush toilets, do laundry, and water the lawn.

How Much Should I Expect To Pay For A Whole House Water Filter?

Systems marketed as whole home water filter systems can range in price from less than $100 to $10,000.  Because the system is installed on the main water supply line, these systems typically require a licensed plumber for installation, which can add considerably to the overall system cost.  

Replacement cartridges can also be a significant cost for  whole house filter systems.  Because ALL incoming water is filtered by whole house systems, cartridges need to be replaced more frequently than if the same cartridge is used in a point of use application.

How Effective Are Whole House Water Filters?

Chemical Removal 
With whole home water filters, you typically get what you pay for.  Most whole house systems are designed to process large volumes of water for water softening and chlorine removal, and are not designed to remove things like chloramine, arsenic, disinfection byproducts, or lead.  If you spend several thousand dollars on a high-end whole house system, pay to have it installed by a plumber, and replace the filtration media as prescribed, the system will probably perform as advertised. Just make sure that the system is designed to filter the chemicals you want removed... we have talked to people that have spent thousands on a whole house filter only to learn after the fact that it does not filter lead!  On the other end of the price spectrum, most of the low cost whole house filters are only good for removing sediment from the water, and don't do a good job removing dissolved chemicals.  The other thing to keep in mind is that if you remove chlorine from your home's water at the point where it enters the home, you introduce the risk of bacteria growing in all pipes downstream of the filter, because the filter removes the disinfectant.

Flow Rate & Impact On Water Pressure
Another performance aspect to consider is the impact on your home's water pressure, because a whole house filter can act as a "choke point" for water delivery.  You don't want to run into a situation where there isn't enough water pressure to take a shower because the dishwasher is running and someone is brushing their teeth.  Be sure to take into account that the cartridges used in single stage whole house filters become clogged over time, and the water pressure can drop dramatically throughout the filter's lifetime.  A good plumber is a very good resource for helping you calculate your home's water demand.  


How Good Are "General Purpose" Whole House Water Filters?

Simply put, it's not possible to build a whole home water filter that "filters everything bad" from your water on a whole house scale.  For that level of filtration, you need to filter at the point of use (e.g. individual faucets- more on this below).  However, there are some applications where whole house filtration makes sense.  For example, we just launched a whole house water filter that is purpose-built to remove sulfur (rotten egg smell) from water.  

Hydroviv’s point of use filtration systems are designed to filter the water in your home used for drinking, washing food, cooking, and showering.  By remaining focused on these applications (and ignoring the water used in toilets & washing machines), we are able offer consumers high-performance water filtration systems that cost less than the competition, and don’t require a plumber to install.  

It's also important to point out that whole home water filters and point of use filters serve different purposes, but they can work well together.  If you have a whole house filter that removes sulfur, it will take some pressure off your point of use system and extend its lifetime.
