Berkey Water Filter Alternatives

Despite all of the good talk above, you might still be contemplating whether the Big Berkey water filter is the right choice for you. You may think that it does not provide you with features that you were expecting or maybe it surpasses your budget by a little.

Berkey knows all of that, and that’s why it has manufactured a wide spectrum of choices fit for all potential buyers. For example, take a look at the following products:

1. Travel Berkey Water Filter

If its compactness and portability was what attracted you to the Big Berkey water filter, you are in for a treat. Our next pick, in the form of the Travel Berkey water filter, comes in with dimensions of 7.5 x 7.5 x 19.0 inches weighing in at 6 lbs. As for the capacity, you get to store about 1.5 gallons at once.

We know you might be thinking that if it is compact, it probably doesn’t provide the same quality of water that you might get with a fully-fledged filtration unit. But that’s just not the case here. It comes with 2 Black Berkey Filters and 2 Fluoride Filters, which allow you to extract harmful chemicals, bacteria, and parasites, and much more from untreated water. In fact, it is so good that you can even fill it water straight out of a dirty pond and the resultant will still surpass American standards. You are also able to filter up to 2.75 gallons of water an hour (that’s 20 bottles of water) with this product.

2. Royal Berkey Water Filter

Most people in the US live in a household consisting of 2 to 4 people. Hence, getting a Big Berkey water filter makes the most sense as it’s perfectly designed to fulfill the needs of small to medium families. However, there are many cases wherein we see families of up to 6 people and in that case, you might have to opt for another water filter or install a second Big Berkey in your house. Well, you don’t really need to if you get the Royal Berkey water filter.

The Royal Berkey comes with a 3.25-gallon capacity outclassing the Big Berkey by a whole gallon. It is also said to be 14% faster in terms of filtration although the quality and procedure of filtration is similar in both of them. Putting things into perspective, it can remove more than 99.999% of viruses and greater than 99.9999% of pathogenic bacteria, while also removing or dramatically reducing protozoa (such as giardia and cryptosporidium), trihalomethanes, inorganic minerals, heavy metals (including arsenic, lead, mercury, chromium), pharmaceutical drugs (including caffeine, Acetaminophen, Ibuprofen, Progesterone, Triclosan).

Yes, the black filters used in the Big Berkey water filter can remove up to 95% of lead and a plethora of other metal-based contaminants.

Q. Which is better, Big Berkey water filter or a reverse osmosis filtration system?

Reverse osmosis filtration systems are commendable in their own right. In fact, they are one of the best water filtration techniques out there as they can produce near-perfect filtered water. However, with that near perfection comes the loss of nutrition as it also tends to remove most of the minerals in water that is good for you.

Big Berkey water filter on the other hand is an extremely smart system. It is made in such a way that only contaminants that are bad for you are removed during its filtration process. That is because it uses a classic stainless steel design and a gravity-fed filtration technique to filter its water.

Unfortunately not. Despite its supreme purification, Big Berkey is quite ineffective at enhancing taste especially if it is salty.

Berkey manufactures several water filters as per the requirements of the users. The Travel Berkey is their most compact water filter. It is only 6 lbs in weight and can store up to 1.5 gallons. So, if you are an individual or a couple, this is the product we would recommend.

For medium-sized families (up to 4 people), we recommend the Big Berkey as it can store 2.25 gallons and is only a little heavier (and larger) than the Travel Berkey. If you are more than 4 people, we would recommend you going for the Royal Berkey (or the Imperial Berkey).
