How to Use the Ceramic Filter

A simple step-by-step guide to prepare, install, clean, and care for your ceramic filter.

Step 01

Prime the Filters Before Use

Before installing the ceramic filter, position the washer and wing nut correctly, then rinse the filter under running water.

1
Remove the wing nut and filter washer, then place them back in the correct position on the threaded stem.
2
Make sure the washer and wing nut are seated properly so the filter can be installed securely.
3
Rinse the ceramic filter for at least 60 seconds, or until the water runs clear.
Tip: Rinsing before use helps remove loose particles from the filter surface.
Visual Guide Assemble → Tighten → Rinse
Place the washer and wing nut on the filter stem.
Tighten the wing nut until the parts fit correctly.
Rinse under running water for at least 60 seconds.
Step 02

Install the Filters in the Upper Chamber

Insert the ceramic filters through the holes in the upper chamber and secure them with the washer and wing nut from below.

1
Place the threaded rod of each ceramic filter through a washer and insert it into the hole in the upper chamber.
2
From below, add the remaining washer and wing nut in sequence.
3
Tighten securely to create a stable seal and complete the installation.
Tip: Tighten firmly, but do not overtighten.
Visual Guide Upper Chamber → Installed System
Insert the filters into the upper chamber and secure them below.
Your filtration system is ready once both filters are installed.
Step 03

Clean the Outside of the Filter

If buildup appears on the ceramic filter, gently rinse and scrub the outer surface only to help restore performance.

1
Carefully remove the ceramic filter from the filtration system.
2
Rinse the outside surface under clean running water to soften buildup.
3
Use the rough side of the included sponge to gently scrub the outside surface in a circular motion.
4
Rinse again to remove loosened particles, then reinstall the cleaned filter.
Important: Clean gently. Do not apply too much force, and do not clean inside the filter.
Visual Guide Rinse → Scrub Outside → Rinse Again
Rinse the outside of the filter under clean water.
Gently scrub the outside surface with the included sponge.
Rinse or wipe the outside clean, then reinstall.
Note: This step is for cleaning the outside surface of the ceramic filter only.
Step 04

How It Works

How Gravity Filtration Works

Water flows from the upper chamber through the filter elements by gravity, then collects in the lower chamber and is ready to dispense.

1. Add Water

Pour water into the upper chamber. No electricity or plumbing is required.

2. Gravity Pulls Water Down

Water naturally moves through the filter elements by gravity.

3. Filtered Water Collects Below

Filtered water collects in the lower chamber and is ready to pour from the spigot.

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

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.

Great Tasting Water

I’m very happy with these ceramic filters. The quality feels solid and well-made, and installation was super easy—just a quick swap and they were ready to go. Cleaning them is simple too, which makes maintenance no hassle. The water tastes fresh, crisp, and way better than before, with no chlorine or strange aftertaste. Compared to Berkey’s brand, these perform just as well (if not better) while being more affordable. Overall, a reliable and high-quality product that delivers on its promises. Highly recommended!

Works well with my Berkey.

Bought these because my regular supplier is always out of stock. I think these are going to be my go to from now on as they are cheaper and honestly they seem to be the same quality. Easy to install, great price and delivered in a timely manner, which is important if you need a new filter and can't wait. Notice a change in the water quality right away once I installed them. A+ rating and a nice headache free experience.

Great quality filters !

If you have a berkey water system you know that the water filters can be a little pricey. Why spend the money on expensive filters?When you could buy these filters that do the same thing and last longer. We have been using these filters for several weeks now. As long as you follow the instructions for installation it does go pretty smoothly . We have had zero complaints since we have been using the these filters. There is zero smell to the water and the water taste great. With these filters last a bit longer ten thousand gallons to be exact. A great quality product at a reasonable prixe .I would not hesitate to get more of these.

works well

The two filters I received worked perfectly! Used one to replace the original one and save the other one when the 1st one needs to be replaced. The swap was a breeze, and they worked just like the originals did when it came to priming and getting them ready. Everything’s working great now!

Good replacement filters.

I have Aquacera gravity filter and these filters are a great fit. They quality is great and seems to be working great. Water tastes great as with the original filters. The flow/speed of water through the filters is also great.

Good fit

These fit well and function well, and they seem to do the job. I don’t have any sort of device to measure water purity, so I can’t really speak to their effectiveness, but when it comes to cost, they are much cheaper than the brand name filter replacement replacements. They pretty much look the same!
