The Benefits of Whole House Water Filtration Systems

When you install a whole house water filter you have access to cleaner, healthier and better-tasting water at every outlet in your home – for drinking, cooking, showering, bathing, brushing, doing laundry, etc.

This will benefit your health in a number of ways:

  • Your drinking water contains less/no contaminants. The same goes for water used for cooking. Which contaminants? The right whole house filter for your water supply can remove lead, chromium 6, arsenic, chlorine & chloramine, sediments, bacteria and many more water pollutants associated with cancer and other diseases.
  • Showering and bathing with filtered water supports healthy hair and skin. People suffering from brittle hair or hair loss and skin conditions like dermatitis, eczema and psoriasis will notice the difference immediately! Your indoor air quality will improve, too!
  • Filtered water tastes and smells a lot better promoting optimal hydration.

Other benefits include:

  • Making cost savings when switching from bottled water to filtered water, which also reduces plastic waste and your carbon footprint.
  • Your entire plumbing system and home appliances are protected from corrosion, scaling and clogging. This will extend their lives, and reduce maintenance and repair needs and costs.
  • Water pressure in your home will be at its optimum.
  • Washing with filtered water also means cleaner laundry and dishes.

Whole House Water Filter FAQ

black question mark icon

Can you drink whole house filtered water?
Yes, you can! However, the level of water purity depends on the type of filter you’re using and the filtration process the system applies. For example: Water filtered with a whole house water filtration system based on catalytic activated carbon + KDF will do a better job at making your home water safe and healthy than a simple sediment filter cartridge.

How long do whole house water filters last?
This depends on the type of whole house water filter system you’re using, the water quality and your water demand. Most filter cartridges need replacement every 3 to 6 months on average. A large filter media bed can last for years without renewal.

What happens if you don’t change your whole house water filter?
If you don’t change your whole house water filter on time, you might experience a drop in water pressure in your entire home due to clogging of the old filter element. Also, a worn-out filter may not reduce as many contaminants as one in working condition and it may be harvesting bacteria or other harmful germs. This can affect filtered water quality and thus your health, and your pipes and appliances.

How do you size a whole house water filter?
Most importantly, when sizing a whole house filter system you need to consider your peak water flow rate. This is the amount of water people are simultaneously using in your home at times of peak consumption. Flow rates are measured in gallons per minute (gpm).

How many gpm do I need for a whole house filter?
We can only provide rough estimates here: Homes with 1-3 baths need about 9 gallons per minute. For 4-6 bathrooms, calculate with 12 gpm. Even larger households should look for a whole house water filter that can provide at least 17 gpm.
