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.

Tony Daniels (Decatur, Georgia, United States)

Did a great job filtering our well water. Took care of the unseen contaminates. Also using ultraviolet filter, works great!

Alberto Carranza (Hawthorne, California, United States)

I and completely satisfied with the service and product delivered on time

Gary Brown (Houston, Texas, United States)
Still early

Not sure how they will work. Will need to wait for some time.

Preston Norrick (Indianapolis, Indiana, United States)

The filters work good, but it fails to filter as much as I had hoped it would. My water is very rusty before the filters and it's still a bit rusty after the filters, but it's still a lot better than not having the filters at all.

Steven Hohle (Burdett, New York, United States)
Mostly excellent system

I bought the Big Blue system for a lake cottage we moved into. The system was easy to assemble and made of quality materials and well designed. Most importantly: the filtration and quality of water is and has been EXCELLENT. The water we drink and use in our home cannot be beat. I have even referred a neighbor who purchased the identical system.
The reason I only rate it 4 stars is because of the seemingly disorganized support from Bluonics. I have received the wrong filters, partial orders, and extended wait times on replacement filters. The Customer Service Rep has always been very pleasant and attentive to my concerns, but little abnormalities in my orders keep cropping up.
Overall, I would definitely recommend the system and the filters, just be prepared to have to deal with them more than normal when it’s time to order replacement cartridges.
