How the Big Berkey Water Filter Works
The big berkey filter technology uses a mix of activated carbon and ion exchange media. This combo removes many contaminants from your water. The water goes through millions of tiny pores in the filter, trapping pollutants through adsorption and absorption.
This berkey water purification process is unique. It removes metals, chemicals, and even tiny viruses without chemicals. The water moves from the top to the bottom chamber by gravity. This makes water filtration in big berkey easy and reliable.
- The Big Berkey removes up to 200 contaminants, including viruses, bacteria, pesticides, PFAS, nitrites, and heavy metals like lead and copper.
- It eliminates 99.9999% of waterborne pathogens and viruses, as well as 99.9% of heavy metals.
- With two Black Berkey Elements, the filtration process takes around 45 to 60 minutes for every 2.25-gallon tank of water.
- Each pair of Black Berkey Elements can filter up to 6,000 gallons of water before needing replacement.
- The entire Big Berkey system costs roughly $0.06 cents per gallon of filtered water, reducing to around $0.03 per gallon after replacing the filters.
The big berkey filter technology and efficient berkey water purification process make the Big Berkey a top choice. It provides your family with clean, safe, and great-tasting water at a good price.
Factors Affecting Filtration Speed
The speed at which a Big Berkey water filter works can be changed by several things. Knowing these can help you get the best results and keep your water clean.
Number of Filters
How many filters you have in your Big Berkey matters a lot. With two filters, it can filter about 7.5 liters per hour. Adding up to four filters can make it filter faster, purifying water quicker.
Water Level in the Upper Chamber
The water level in the top chamber affects how well the filter works. Having it full helps keep the pressure and flow steady. This makes the filter work better and faster. Keeping the right water level is key for the best results.
It’s also important to prime the filters right. Doing what the maker says will help your Big Berkey work its best.
| Factor | Impact on Filtration Speed |
|---|---|
| Number of Filters | More filters (up to 4) means faster flow |
| Water Level in Upper Chamber | A full chamber means better pressure and flow |
| Filter Priming | Right filter prep is vital for top performance |
“Keeping the water level right and priming filters well are key for the best speed with your Big Berkey system.”
Average Filtration Time for a Full Tank
The Big Berkey water filter system is known for its fast water filtration. It takes about 45 to 60 minutes to filter a full 2.25-gallon (8.5-liter) tank. The time can change based on the number of filters and the water level.
With two Black Berkey filters, it filters a full tank in about 3.5 hours. Adding four filters cuts the time down to around 1 hour and 10 minutes. This is because more filters mean faster water flow.
| Filter Configuration | Filtration Time for a Full Tank |
|---|---|
| 2 Black Berkey Filters | ~3.5 hours |
| 4 Black Berkey Filters | ~1 hour 10 minutes |
The Big Berkey uses gravity to filter water, making it great for many sources. But, it doesn’t keep water cold or have insulation.
“The water filtered by the Big Berkey tastes better than bottled water according to user experience.”
The Big Berkey’s filtration time varies from 45 minutes to 5 hours. This depends on the filters and water level. Knowing this helps you get clean, tasty water quickly.

Typical Flow Rate for Different Filter Configurations
The Big Berkey water filter’s speed changes with the number of filters. With two Black Berkey filters, it filters about 7.5 liters (2 gallons) per hour. Using four filters boosts this to 26.5 liters (7 gallons) per hour. This is all done by gravity, without electricity.
The Fluoride Filter slows things down by catching fluoride and arsenic. Also, if the top chamber isn’t full, the filters work harder. This makes the water flow slower.
Keeping the filters clean is key to a big berkey water filter flow rate and big berkey filtration speed. Fixing air bubbles can also boost the berkey water filter gallons per hour and big berkey filter capacity.
To filter water well, know your Big Berkey. Check the lower chamber to avoid spills. Make sure the upper chamber is full. Soak the purification elements in water for 30 to 60 minutes before use. And, throw out the first water collected in the lower chamber.
Troubleshooting Slow Filtration
If your Big Berkey water filter is slow, there are steps to fix it. First, make sure the filters are clean and primed right. Dirt and sediment can block water flow and slow down the filter.
Air bubbles in the system can also slow things down. Use the anti-airlock clip and adjust the upper chamber to get rid of these bubbles. This will help your filter work faster.
Cleaning and Priming the Filters
Cleaning and priming your Big Berkey filters is key for good water flow. Here’s how to do it:
- Take out the filters and rinse them well under water.
- Scrub the filters gently with a kitchen scourer or soft brush to remove dirt.
- Soak the filters in clean water for 15-20 minutes to loosen more dirt.
- Rinse them again under water to get rid of any leftover debris.
- Prime the filters by soaking them in water and shaking them gently to remove air.
Addressing Air Bubbles and Sediment
Air bubbles in the Berkey system can slow down filtration. Here’s what to do:
- Make sure the upper chamber is aligned and seated right on the lower chamber.
- Use the anti-airlock clip to release any air bubbles trapped inside.
- If you have sediment buildup, try backwashing the filters by reversing the water flow.
Regular cleaning, priming, and fixing air bubbles or sediment will keep your Big Berkey filter working well. This ensures fast and effective water filtration.
Benefits of Slow Filtration
At first, slow filtration might seem like a drawback. But the Big Berkey’s gravity-driven process has many benefits. Its Black Berkey filters have a unique design. This design allows water to flow slowly, ensuring it meets high standards of purity.
This slow flow helps keep important minerals in the water. It also makes the water cleaner than faster methods. These methods might miss some impurities.
The Big Berkey is great at removing many contaminants. It can get rid of heavy metals, bacteria, and viruses. This thorough purification means your family can drink safe water.
Also, the slow rate helps the filters last longer. You won’t need to replace them as often. This saves money and hassle.
The Big Berkey’s slow filtration also means a steady water flow. Unlike fast systems, it doesn’t have flow rate issues. This makes it perfect for daily use and emergencies.
In summary, the Big Berkey’s slow filtration has many benefits. It removes contaminants well, keeps minerals, and lasts longer. It also provides a steady water flow. These reasons make it a top choice for clean water at home or for emergencies.
“The slow, methodical filtration of the Big Berkey helps preserve the beneficial minerals in the water and produces a higher quality, cleaner end product compared to faster filtration methods.”
Maximizing Filtration Efficiency
To get the most out of your Big Berkey water filter, follow some important steps. First, make sure it’s installed correctly, following the manufacturer’s guide. This means all parts are in place and securely fastened.
Next, clean the filters regularly. Use a scouring pad to remove any built-up contaminants. Also, replace the filters when they can’t purify water as well as before.
Proper Installation and Maintenance
Keeping the upper chamber full is crucial. It helps maximize the Big Berkey’s filtration performance. Also, fix any air bubbles to keep the water flowing smoothly.
By following best practices for Big Berkey use, you’ll keep your filter working well. This ensures you have clean, purified water for years.
By optimizing your Big Berkey filtration, you ensure it’s working at its best. This means you and your family get the best drinking water possible.
