The Heavy-Duty Whole House Filter delivers clean and clear water to every faucet and showerhead in the home. With two stages of filtration, this unit utilizes oversized filter cartridges (20" x 4.5" aka Big Blue) and large 1" ports to reduce the pressure drop in any home. Perfect for offices or homes with limited space, or places incapable of having backwashing filters, or having the need of cartridges. Our units come fully built and ready for installation.

So what makes these different than everyone else? Most competitors use a smaller filter cartridges (ex: 10" x 2.5") with smaller ports. Although these units may be fine for small homes or offices, they will not effectively remove all contaminants for larger homes that demand a high flow rate.
