The Single Stage Whole House Sediment Water Filter uses Big Blue filter cartridges (20" x 4.5" aka Big Blue) and large 1" ports are used to reduce the pressure drop in any home. 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.

Fit for Large Homes
I bought this product after seeing the description that it fits for larger homes. I feel the same after using it in my home but I also bought some Chlorine test strips too and I can tell its working. I guess filtered water feels the same.
