How to Set Up Your Countertop Gravity Water Filter System

Prepare and Clean the Parts

Before assembly, check the main parts and clean the system components.

  • 1
    Wash Your Hands Handle the system with clean hands before setup.
  • 2
    Check Included Parts Make sure the chambers, lid, spigot, stand, and core filters are ready.
  • 3
    Clean Before Assembly Rinse the chambers and accessories before first use.
Note: Use cold or room-temperature water only. Do not use hot water.

Assemble the Lid Knob

Attach the lid knob to the lid and secure it with the included hardware.

  • 1
    Place the Lid Knob Insert the lid knob into the center hole of the lid.
  • 2
    Add Washer and Gasket Place the washer and gasket in the correct position.
  • 3
    Tighten the Screw Fasten the knob until it feels stable.
Tip: Do not overtighten. The lid knob should feel secure but not forced.

Install the Basic Spigot

Install the basic spigot into the lower chamber before stacking the system.

  • 1
    Insert the Spigot Place the spigot through the lower chamber hole with the gasket and washer.
  • 2
    Add the Inside Parts Place the remaining washer and gasket from the inside of the chamber.
  • 3
    Tighten the Hex Nut Use the wrench to secure the spigot vertically.
Before filling: Make sure the spigot is closed to help prevent leaking.

Install the Core Filters

Use the required number of core filters for your system model.

  • 1
    Insert the Core Filters Place the core filters through the holes in the upper chamber.
  • 2
    Secure the Filters Use the filter washer and wing nut to hold each core filter in place.
  • 3
    Check Stability Make sure each core filter is firmly installed before adding water.
Note: This guide uses “core filters” only. Filter type and quantity may vary by system option.

Stack the Chambers and Stand

Set the system together in the correct order before flushing.

  • 1
    Attach the Anti-slip Mat Place the anti-slip mat on the bottom of the lower chamber.
  • 2
    Place the Lower Chamber on the Stand Set the lower chamber securely on the stand.
  • 3
    Add the Upper Chamber and Lid Place the upper chamber into the lower chamber, then cover it with the lid.

Flush Before First Use

Flush the system before drinking water from it for the first time.

  • 1
    Fill the Upper Chamber Add water and let it move through the core filters.
  • 2
    Discard the First Batch Pour out the first filtered water from the lower chamber.
  • 3
    Repeat 2–3 Times After flushing, the system is ready for regular use.

How It Works

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.

1. Fill the Upper Chamber

Add water to the top chamber. The system works without electricity, plumbing, or pressure.

2. Gravity Moves Water Through the Filter

Water naturally flows downward through the center filter element, where the filtration process takes place.

3. Filtered Water Collects Below

After passing through the filter, water collects in the lower chamber for storage and daily use.

4. Dispense When Needed

Open the spigot to pour filtered water for drinking, cooking, or everyday hydration.

Filter Replacement

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.

!
Track Usage Time & Filter Life

Filter life may vary by water quality, usage frequency, and total water volume filtered.

Rated Filter Life Reached

Replace the filters when they reach the rated lifespan listed for your filter model.

Water Flow Becomes Slower

If filtering takes much longer than usual, clean or replace the filters as needed.

Taste or Odor Returns

If unwanted taste or smell becomes noticeable again, it may be time to replace the filters.

Source Water Matters

Rain, river, stream, or well water may shorten filter life compared with regular tap water.

What to Check Before Replacing Filters
Confirm Compatibility

Choose filters that match your filtration system, filter series, and setup.

Prepare New Filters

Prime, rinse, or flush new filters according to the product instructions.

Check Seals & Washers

Make sure washers, seals, and threaded parts are installed correctly.

Clean the System

Empty and clean the upper and lower chambers before installing new filters.

Replace Sets Together

If your system uses paired filters, replace matching filters together when needed.

Record the Date

Write down the replacement date and set a reminder based on your usage.

Filtered drinking water

I consistently reorder this product. It lasts between 5-6 months. There is a taste to the water but it is pleasant. I have ordered a tester as I would like to see the level of minerals in the drinking water after filtered. I'll update this when I get results.

Fluoride Removal Combination
Purewell water 2.25 gallon

I am enjoying using this, had a few times where it ran out and i forgot to turn the nozzle to off, so it made a big mess once refilled. I wish instructions or a video of putting this thing together was available. I have two extra filters I don't know how to use. Any help with this? I am not gong to be bringing water home from the store anymore. Woohoo! Would definitely buy this again. Thanks

Good Quality

My water is very bad. Lots of iron so I’m happy to get a month out of these filters but the water that is filtered is very good. I’m sure the filter would last longer if the water wasn’t so mineralized

Works great! Better price.

The well water from my tap is wonderful & has no odd taste or smell now. I'm saving $$$ by not buying bottles & it's convenient to use right on my countertop. The unit looks nice as well. Would recommend.

Must be saturated to work properly

The package was missing any kind of instructions. It won't work (well) unless saturated. Check the original instructions from the gravity filter or google how to saturate gravity filters. After saturation works great. Would buy again.

First delivery was damaged in transit or delivery

Filters work fine, but between the manufacturers packaging and Amazon not boxing them additionally they are very much too fragile and may not survive normal delivery.

Filters So Well

I use these in my Purewell, and pour my well water in it. Even if there's a little sediment in my water, it is filtered out, and is great. Buying the Purewell and filters was a smart buy!
