1 Standard Size 4.5”x 20” ( 20 Micron) Sediment Filter. Filters sediment particles such as silt, sand, rust, dirt, and other undissolved particles.

Melt-blown Polypropylene Sediment Filters. The main function of a sediment filter is to remove large and fine particles from our drinking water, such as sand, dirt, silt, and rust particles.

Our Sediment filters are made of fine melted polypropylene, which is then blown and spun in a cylinder-like form.  These filters have a lower density at the surface of the filter with progressively higher density toward the center which enables to capture of particles throughout the entire filter depth.

This translates to a longer life and allows better performance of all the following filters, such as Carbon Block or GAC filters.

1 Standard Size 4.5”x 20” Block Activated Carbon Filters (5 Micron) – Block Carbon Filters (5 Micron) are similar in their performance to that of granulated GAC filters, being made of fine coconut shell charcoal carbon tightly compressed forming a cylinder block. Solid-block activated charcoal is superior at adsorption because all the water molecules are forced to travel through the compressed charcoal. Also since it is made of packed carbon it helps to trap suspended particles and dirt.

1 Standard Size 4.5”x 20” ( 1 Micron) Sediment Filter. Filters sediment particles such as silt, sand, rust, dirt, and other undissolved particles.

whole house

I put in this filtering system last years in July when I was moving into a new home. Prior to this I had always had spring water but now I am on a municipal water.
This filter system is fantastic and removes all the nasty odors and junk that these water companies insist on using. Great whole house filter system.

Great filtration system for my well

Before installing this system, we were experiencing a very strong sulfur smell but after installing the 3 filter system and the UV light system, our water hasn’t had that sulfur smell since. I’ve had the filters installed for almost a year now and my water pressure has remained unchanged. I just purchased a double set of new filters and UV bulbs and will be replacing prior to the sale of our home sometime in December. Overall a great system if you have the extra wall space to install everything. I contacted a plumber to install the system and he wanted $1,500 so I did it myself with the Shark Bite fittings and was done within a couple hours.

Still amazed

In a world where everything that you attempt to purchase is “ stuck on a ship off the coast of California “ these people/business still delivers, no excuses no b.s. , just straight up delivery. Wish that the other 99.9% would emulate, even just a little.
