The WD-WHF21-PG whole house water filtration system effectively intercepts large particles, such as sand and rust. It features a longer lifespan, saving you potential replacement cost. You can enjoy clean, safe water for a long time at an affordable price while saving costs. This whole house water filtration system also protects your water-related appliances and prolongs their lifespan. By reducing particles at the first line, it further prevents potential clog and accumulation of rust in the water filter system. In the end, you spend way less on maintenance.

The whole house water filter system is composed of a PP filter and a GAC filter. The PP cotton helps intercept large particles, such as sediments, rust, dirt, and grit. The GAC filter adopts natural coconut shell, which effectively filters out chlorine and odor, and also improves water taste.

The home water filtration system guarantees a long lifespan. The GAC filter should be changed every six months, while the PP filter should be changed every 3-6 months.

No, the home water filtration system won’t reduce water pressure. The 1” water outlet ensures large water flow without affecting water pressure significantly.

The installation is so simple that you can do it on your own following the instructions in the manual. The included wrench facilitates the replacement, installation, and related processes.

The O-ring may not be in place or there is not enough Teflon tape on the thread. Please reapply the Teflon tape and tighten it. If it still leaks after adjusting the O-ring or threads, please contact our customer service.

The pressure release button has a screw under the bracket. Tighten the screw and this should stop the leak.

The filters may be installed incorrectly. Check to see if a piece of the plastic wrapping is still protecting the filter. Likewise, any high-flow situation within the first 72 hours after installation may cause a temporary carbon blockage. To clear the blockage, turn off any running water for at least 10 minutes and resume using water at low or normal flow rates.
