How the Filter System Works
Water is added to the upper chamber and moves through the center filter by gravity. After filtration, water collects in the lower chamber and is ready to dispense from the spigot.
Add water to the top chamber. The system works without electricity, plumbing, or pressure.
Water naturally flows downward through the center filter element, where the filtration process takes place.
After passing through the filter, water collects in the lower chamber for storage and daily use.
Open the spigot to pour filtered water for drinking, cooking, or everyday hydration.
Filter Replacement Guide
Replacing filters on time helps your filtration system keep working properly. It also helps maintain water flow, drinking water taste, and everyday use confidence.
Filter life may vary by water quality, usage frequency, and total water volume filtered.
Replace the filters when they reach the rated lifespan listed for your filter model.
If filtering takes much longer than usual, clean or replace the filters as needed.
If unwanted taste or smell becomes noticeable again, it may be time to replace the filters.
Rain, river, stream, or well water may shorten filter life compared with regular tap water.
Choose filters that match your filtration system, filter series, and setup.
Prime, rinse, or flush new filters according to the product instructions.
Make sure washers, seals, and threaded parts are installed correctly.
Empty and clean the upper and lower chambers before installing new filters.
If your system uses paired filters, replace matching filters together when needed.
Write down the replacement date and set a reminder based on your usage.
Use this checklist to choose the right replacement filter for your Purewell system and check whether it may also fit select compatible systems from other brands.
