Water Filter Systems

The Best Water Filter Systems for the Best Water Quality

You can say goodbye to harmful contaminants and hard water once you install one of our systems. A Berkey water filtration system is an excellent choice for achieving better water that is safe and delicious. If you are looking for pure water from your home’s water supply, a Clearbrook water filter is another fantastic option.

Both systems are highly effective at filtering out heavy metals, chlorine, and other harmful chemicals, providing you with peace of mind every time you take a sip.


Get Filtered Water Straight from the Tap

Enjoy the benefits of purified tap water without any extra appliances on your counter. Clearbrook's selection of under-sink filters offers a seamless way to improve your water quality. These compact systems fit conveniently beneath your kitchen sink, providing you with clean water on demand.

The Clearbrook OSF-12 is a sleek, stainless steel unit that connects directly to your existing plumbing. It is designed to reduce chlorine, lead, mercury, and PFOA/PFOS, with a filter life of up to 800 gallons. For more comprehensive filtration, the Clearbrook SF-D12-P and Dual In-Line systems use a two-stage process.

They first remove up to 95% of fluoride, followed by a Gen IIII filter that targets 99.99% of chlorine, heavy metals, and other taste-affecting contaminants. Both the single and dual-stage systems are built for simple, tool-free installation and feature a quick-change design that makes replacing filters a breeze.

Frequently Asked Questions

+ What is a water filter system?

A water filter system purifies water by reducing or eliminating contaminants, providing clean drinking water. These systems use various methods, such as activated carbon, to improve quality and taste.

+ What are the benefits of using a water filter?

Using a water filter offers many benefits, including removing harmful chemicals and heavy metals, improving the taste of water, and reducing your reliance on bottled water.

+ Is filtered water safe to drink?

Yes, filtered water is safe to drink. These systems, including Berkey and Clearbrook, are designed to remove contaminants, ensuring that your drinking water is clean and pure.

+ Do these filters remove Fluoride?

Standard carbon block filters reduce many contaminants but may not remove Fluoride entirely. For Berkey systems, you must attach separate PF-2 Fluoride Reduction Elements. For Clearbrook, the SF-D12-P Dual Sink system is specifically designed with a dedicated stage to remove up to 95% of fluoride.

+ How often do I need to change the filters?

This varies by model. A pair of Black Berkey Elements can treat up to 6,000 gallons. Clearbrook OSF-12 is rated for 800 gallons, while the dual-stage sink filters can last up to 8,000 gallons depending on sediment levels.

+ What is the difference between a water purifier and a water filter?

The difference between a water purifier and a water filter is that a water purifier removes viruses, which are smaller than bacteria. A water filter removes contaminants like bacteria and chemicals.

+ Can I clean the filter elements?

Yes, many gravity-fed elements like the Black Berkey and the Clearbrook CB9 are re-cleanable. If the flow rate slows down, you can scrub the exterior of the element with a Scotch-Brite pad under running water to expose a fresh layer of carbon and restore flow.
