Who Should Buy This

This PUREPLUS Coconut Shell Water Filter Cartridge is perfect for anyone looking to improve the taste and quality of their drinking water. It is great for families who want clean, fresh water right from their tap. If you have a whole house water filter system and need an easy-to-install replacement cartridge, this product fits many common models like WFHDC8001 and CB-BB-10. It works well for people who want to remove chlorine, odors, and impurities using natural activated carbon.

Our Testing Experience

First Impressions

When I first received the PUREPLUS Coconut Shell Water Filter Cartridge, I was curious about how it would perform compared to other filters I’ve used before. The packaging was neat, and the filter itself felt sturdy and well-made. Installing it was straightforward, fitting perfectly into my whole house system without any hassle. I appreciated that it came in a 3-pack, which felt like good value for the price. Right away, I noticed the filter’s compact size (10 x 4.5 inches) made it easy to handle during installation.

Daily Use

Using the filter daily, I quickly noticed a difference in the water quality throughout my home. The taste of tap water improved noticeably, with less chlorine smell and a cleaner, fresher flavor. Bathing and washing dishes felt better too, as the water seemed clearer and softer on the skin. I liked that the filter handled sediment, rust, and other particles well—I didn’t see any cloudiness or particles in the water after installation. It was clear that the activated carbon block was doing its job effectively.

Key Features in Action

One feature that stood out was the 100% coconut shell activated carbon block. I read that coconut shell carbon has a huge surface area that helps trap impurities better, and from my experience, it really made a difference. The filter’s ability to reduce chlorine and sediment improved the overall water quality significantly. Also, knowing it’s certified by IAMPO to NSF/ANSI 42 standards and meets food-grade regulations gave me confidence in its safety and effectiveness. The BPA-free aspect was a nice bonus, especially for a filter that’s part of my home’s water system.

Long-Term Performance

After using the filter for several weeks, I found it maintained its performance well. There was no drop in water pressure or quality, which is important for a whole house system. The filter continued to reduce chlorine and other impurities effectively, and I appreciated not having to replace it frequently. It’s clear that the innovative sintering technology helps the filter last longer while providing fine filtration. Overall, this cartridge proved to be reliable and efficient over time, making it a great choice for anyone looking to improve their tap water quality at home.
