Why You Need Royal Berkey Water Filter in Your Home

Worldwide customers have supported our Berkey systems regarding the trusted filtration system. Berkey has become a trusted name in more than 100 countries across the globe.

That is not surprising since Berkey is not only effective in purifying water sources, but it is also quite efficient.

Berkey water filters are usually very versatile products. They were not only designed for home, but they were also portable to make it easy for you to bring them along on your outdoor adventures.

The Berkey systems also do not require any special equipment or electricity to make them work, and it is just pure gravity. They can also purify treated not only water but also untreated raw ones from lakes and other natural sources.

The Royal Berkey Water Filter

If you need a water filter system for your home that could cater to your whole family, then the Royal Berkey is a good choice. This filter system is a bit bigger than the Big Berkey since it was designed to increase the size.

This water filter system results from a lot of customer feedback saying that Big Berkey cannot keep up with the water demands of their family because although they are just a family of normal size, their water consumption and demands were higher than normal because of a unique lifestyle. 

We have listened to what our customers say and discovered that this group uses water for drinking and other things like cooking, plants, and pets.

People in this household could also have an active lifestyle requiring more water than normal.

People in this group needed a Berkey filter that could offer a much larger capacity, so the Royal Berkey Water Filter was made.

Like all other Berkey Water Filter systems, the Royal Berkey can remove 99.99 percent of water contaminants.

It can filter out harmful bacteria, cysts, harmful minerals, organic solvents, harmful chemicals, and parasites in your drinking water.

Although this is a very powerful water purifier, it still leaves the entire healthy mineral in the water we will need.

Its storage capacity is 12.3 liters or 3.25 gallons. The purification elements can also be expanded to four to purify up to 30.3 liters or 8 gallons of water in an hour.

The Royal Berkey water filtration system is ideal for larger families and people leading an active lifestyle with more clean and healthy drinking water demands.

Royal Berkey Purification Elements

The Royal Berkey has two Black Berkey Purification Elements. You must know that it is more powerful than any of the current gravity filter elements.

When tested, the purification elements removed 99.99 percent of the contaminants, and no pathogens were detected even when tested under an electron microscope.

Each of the purification elements can last you up to approximately 3,000 gallons, so a set of two will give you approximately 6,000 gallons of clean and safe water. That means those two filters could last you for many years, making the Royal Berkey water filter system a good choice for a home filtration system and a smart and affordable one since it could help you save money in the long run.

Customer Reviews

Based on 239 reviews

We already had good well water, but this filtration system takes it to a whole new level. The instructions were easy enough to follow, and it went together easily. Struggled a tiny bit priming the black filters, but that was because of my faucet being too big for the priming adapter. We got them primed and performed a leak test, then the red dye test. It all went without a hitch, and now we're enjoying cleaner filtered water in our home. Thanks for being a great product....


Set up the Berkey and the water tastes great! Wish I would have ditched my Aqua Tru a long time ago!

Well made and arrived in perfect condition. We were going to save it for emergencies but instead we use it for every day drinking water.

Royal Berkey gravity purifier

Love My Berkey

I got sick of buying bottled water as we have a stinky well at home. This filter system is going to save us money and it tastes great and no smell! I bought some glass bottles so the kids can still have their bottled water. I highly recommend Berkey.

Hollis Schaefer
Royal Excellence !

So glad we bought the larger ROYAL size as the two of us are big water users ! Excellent quality and we are eager to add fluoride filters when available !

Mary Beth Steinel (Belpre, US)
Slow filters?

I love the taste of the water but the first two filters that came with it were SLOW, like 2 gallons in over 24 hours. I did everything, cleaned redid everything according to directions. I ordered two more thinking maybe I had to put 4 in. I put one more in and boom, 3 gallons in a matter of hours, not days. I think when I clean it this week, I am just going to leave one of the old, i would just leave the new to see how long but I only have 2 plugs.
🤷‍♀️ Water tastes great but I was very frustrated at how long. So, I don’t know if my first two were bad.

Michelle Garner (Clyde, US)
Can’t put it together

I think it’ll be wonderful, but we are still struggling to get it fully put together.
