Aquaboon 4,5 x 20 inch Carbon Filter Cartridge - 5 Micron Coconut Shell CTO Big Blue Filter - Whole House Well Water Filtration - Matches DB20P, CTO20BB, Pentek FLOPLUS-20BB, 155312-43 (2 Pack)

These filters are great! I have had a whole-house water filter for 15 years, and love it. Though I have city water, the specs state that this filter also is great for well water.

the filter works great. It improved the taste of our city water, it works much better than other filters we have tried here on Amazon. Highly recommend using them.

Good product recommended to me by my plumber!

Water quality is better after this filter installed

Great price for this filter. Well made and performs well. Much better value than the pentair version which is more than double the price.

These filter are quality. Come in protective packaging. Half the price of another major manufacturer. Fast delivery. Will purchase more in future.

I used these on my "Twice the Ice" ice houses and they work very well. My machines sell ice and water and filtration is key to clean, clear ice and water. These do the job exceptionally well.

Priced very well and was easy to install

This carbon water filter is of great quality and works perfectly as a replacement part for home water filtration systems. It fits well, is easy to install, and effectively improves the taste and clarity of the water. The filtration is efficient at removing impurities, and we’ve noticed a significant difference in the water’s quality since replacing the old filter. Overall, this is a reliable and high-performing option that provides great value. Highly recommend for anyone looking to replace their water filter with a durable and effective part!

Absolute garbage. You know that saying you get what you pay for this is one of those things. Installed on a home with big blue water filter system on city water and this got totally clogged within 2 months and I had terrible low water pressure in the house. Pulled it out and the inside of the filter was falling apart. Put the big blue back together without this filter house pressure back to normal. Waiting for my usual filter brand (which by the way costs x2 as much) to arrive and will install as I have never had this issue before. Thought I would try something else and save a few bucks but was wrong. Guess I will just be throwing the 2nd filter I got with this away what a waste.

The boxes looked good and an initial look at the filters were fine so I stored them for when I needed them. I’ve now gone to use them and after pulling them fully out of the box both filters are cracked on one end. Very disappointing.

Didn’t work for us in our system

Does the job for a fair price
