ProOne Big+ Gravity Water Filter System

No, the ProOne Big+ is a gravity-fed system. It works by simply pouring water into the top chamber, allowing gravity to pull it through the filter into the lower reservoir, making it completely independent of electricity or plumbing connections.

The included ProOne G2.0 filter is designed to reduce over 200 contaminants, including lead, bacteria, and volatile organic compounds (VOCs). It is independently tested to meet NSF/ANSI 42 standards for component quality.

The system has a 3-gallon capacity, which is suitable for daily use in a household or for emergency preparedness. The unit measures 9 inches by 22.75 inches, so ensure you have enough vertical clearance on your countertop.

Yes, the housing is constructed from 304 stainless steel, which is known for its durability and resistance to rust. The manufacturer also backs the stainless steel components with a 5-year limited warranty.

The system uses a manual filter indicator, meaning you will need to track usage yourself to know when to replace the filter. Since it is a gravity-fed system, you should also periodically clean the stainless steel chambers to ensure optimal water flow and hygiene.

The ProOne Big+ is primarily designed for use with tap or municipal water sources. While it is a robust filtration system, it is best to verify the specific quality of your water source before relying on it for untreated water like lakes or streams.
