Big Bubba Filter housings are made of rugged, glass-reinforced polypropylene so they will not chip, rust or dent. Because all wetted surfaces are non-metallic, they are ideal when chemical compatibility is an issue and for seawater applications.

Big Bubba Housings are an economical replacement for stainless steel filtration equipment because of their non-metallic construction and today’s high cost of stainless steel.

Watts whole house filters with our proprietary pleated activated carbon cartridge conserve water because backwashing is not required, making them 100% efficient.
