WSP Whole House Water Filter - Poly Ultrafiltration

Water that delivers a dull taste, cloudy appearance, or odd smell doesn't just affect your enjoyment; it quietly adds up in extra detergent, harder cleaning, and appliances that wear out sooner. The WSP Whole House Water Filter - Poly Ultrafiltration helps reduce those issues by filtering out fine particles, bacteria, and other common water contaminants for your entire home.

The subtle costs of untreated water quality

You might notice a faint film building up on shower doors, or coffee that tastes flat, like it’s brewing through a pool rather than clean water. These are signs of suspended particles and tannins in your water. Over time, that same sediment and organic material can settle inside pipes and appliances. Dishwashers and washing machines may need repairs or replacement earlier than expected. Your water heater’s elements can get coated with scale-like deposits, making them work harder and use more energy. All this quietly adds to your household chores and utility bills.

How the automatic backwash control keeps your filter working

This system uses an automatic backwash cycle controlled by a C-Series valve. Backwashing means the filter cleans itself daily by reversing water flow to lift and rinse away trapped particles from the filter’s surface. You set it once, and the system handles the cleaning automatically, saving you work and making the media last longer. This automatic cleaning helps maintain steady flow and reliable filtration without your intervention.

Polysulfone-based ultrafiltration: what’s inside the tank

At the heart of this system is a fine ultrafiltration membrane made from polysulfone, a tough and chemically resistant material. This membrane works like a very fine sieve, filtering water from the outside inward through tiny pores about 0.02 microns wide. It captures bacteria, viruses, cysts, turbidity (cloudiness), tannins, and fine sediments that standard filters usually miss. The membrane’s design reduces clogging and allows easy cleaning during backwash.

The tank and flow rate suited for larger households

The system’s pressure vessel is built to accommodate the ultrafiltration media and is designed for high flow rates, handling up to 12 gallons per minute. While the exact tank size depends on your specific water conditions and installation needs, it’s made robust and covered by a lifetime warranty on the pressure vessel itself. This capacity supports a large household with five or more people and three to four bathrooms, delivering filtered water to every tap without restricting flow.

Who this filter fits best in your home

This system is ideal if you have a large family or a busy household where water demand is high. It suits homes with multiple bathrooms and appliances running simultaneously. If you have fewer people or lower water usage, a smaller system might be a better fit, but this model ensures you won’t notice reduced water pressure during peak use. Confirm sizing by comparing your household flow needs and water test results.

What’s included and how to proceed

The system comes ready for your licensed plumber to install and includes a bypass valve so you can isolate the unit while keeping water running to your home during servicing. You’ll also receive 10 feet of discharge hose for the drain line. Your investment is backed by a lifetime warranty on the tank, with manufacturer warranties covering the control valve and electronics. U.S. shipping is free and included in the price.

Who this size is right for

This is rated for roughly 12 gallons per minute of service flow, which suits a large home - around 5 or more people with 3-4 bathrooms.

The number to match is peak simultaneous demand, not average use. Two showers and a dishwasher at once is the moment that finds an undersized unit, so size for that.
