4 pcs 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.

They are excellent in removing chlorine, pesticides, herbicides, bad taste & odor, organic solvents, chemicals, and contaminants that contribute to bad taste and odor leaving our water healthier and great tasting.

Very satisfied with Bluonics

Bluonics sent my order quickly and replaced two filters that was damaged in shipping. Will from them again.

Susan Harris (Denver, Colorado, United States)
Carbon filter

Now that I’ve finally been able to get the men to install two carbon filters, and one thread, I’m pleased to report that it’s gotten the rest of the odor out of the water. I was going to return a whole box full of the filters, but by the time I pay the shipping on it, I might as well just hang onto them even though I won’t have a need or use of them. I hope these filters last more than two weeks, before I have to change them out again.

Chris Williamson (Yorktown, Indiana, United States)

I received the BB AC filters in good condition and in a timely manner, Thank you very much! I also have occasional need for Pentek WS cartridges 20"x4.5" and would like to order both types of cartridges from the same source. Could you look into carrying those as well? Thanks!
