OMNIFilter's WH5 whole house clear 10 in water filter system is designed for average size homes with 3/4 in incoming water lines and is ideal for both well water and city water applications. The clear housing allows you see your filter working and gives you an indication as to when to change your cartridge. No need to purchase a mounting bracket since the cap has the mounting bracket built in. A cartridge is not supplied with this system, so you can customize it to your filtration requirements by using any number of OMNIFilter cartridges to filter sediment, dirt, sand, rust particles, chlorine, tastes and odors.
