Best Stainless Steel Water Filter

2023 Buyers Guide to the Best Stainless Steel Water Filter

Stainless steel water filters are great because of their durability.  If possible, test your water source to find the ideal filter solution.  The best stainless steel water filter should be the size that fits your needs, easy to use, and durable on many levels.

Key Considerations To Choose The Best Stainless Steel Water Filter

  • Durability: Unfortunately, durability isn’t just whether or not your stainless steel water filter can survive a drop or two. Stainless steel is generally-speaking, very durable. But, when you look at the design, you will see the opportunity for leaking, tipping, and other minor flaws. Stainless steel design also means that you can’t fix minor issues easily. When looking at stacking stainless steel units you want something that sits flush. Even if the assembly is a bit difficult, a tight fit will fight against leaks. A unit that has gaps between pieces that fit together may also start building up mold or bacteria. Without constant cleaning, a loose-fitting unit will not last for very long. The other aspect of durability is tipping. Because stainless steel filters are usually on the countertop, you don’t want any chance of something holding gallons of water to tip over. Many people opt for built-in or faucet water filters to avoid this possibility.
  • Ease of Installation: Yes, even water filters can be difficult to handle sometimes. But how on earth can a stainless steel water filter have difficulties? Installation is a big deal to a lot of people. Many filter systems stack together. A straightforward assembly. But, others might install into your sink, counter, or onto your existing sink faucet. How do you choose which is right for you? If you don’t feel comfortable installing hardware, stay away from sink-mounted options. You might also want to avoid faucet extensions. However, most of the counter installation or faucet extensions are simple. Detailed instructions on installation will lead you step-by-step through the process.
  • Size: There are various “standard” sizes, but there are issues with the width and height of many stainless steel filter options. A comfortable size for many people is about 14 to 20-inches tall. This height can comfortably sit on a counter that has an overhead cupboard. At this height, you might need to slide the unit out to refill it, but it won’t be a struggle. The second issue to consider with size is your water consumption. If you are only worried about taking care of 1 person’s water needs, you’re in luck. Nearly anything will work for a single person. But, if you have a family or office of people using the same filter you need something that can handle the water use.

The Competition

We have previously included the Big Berkey in our stainless steel water purifier review, but given the carbon filters were taken off the market, we had to remove it from our list until they are available again. Recently the EPA decided to change the Berkey filter’s classification to a “pesticide”. Yes, you read that correctly.

The Big Berkey uses a 9-inch Black Berkey filter.  While the kit comes with two element filters, the Big Berkey is able to hold four if you want to increase flow rate. Unlike other stainless steel water filter systems, this system is self-sterilizing and re-cleanable. These features are outstanding additions for anyone using this system outside of the home.

The Big Berkey is an ideal water filter for camping or in RVs.  You can add untreated water straight from rivers or lakes. This filter captures pathogenic bacteria, parasites, reduces pesticides and herbicides. It can hold 2.5 gallons of water and can filter about 15-gallons of water per day. This water volume is enough for up to 16 adults on a regular basis.

Berkey also has a great alternative for camping or hiking, but again, it is currently unavailable. With a similar design to other stainless steel models, the Travel Berkey Stainless Steel Filter has a few hidden benefits. Its size makes it an excellent choice for anyone living alone. Many stainless steel water filters will hold over a typical family’s water use. However, this model caters to one to three people with its compact size. It can hold up to 1.5-gallons of water in its reservoir and stands at about 18-inches tall. But, when it’s not in use, you can nest the unit at the height of about 9-inches.

It can hold two of the patented Berkey black purification elements that are capable of removing 99.99% of viruses and pathogenic bacteria.  This is important, specifically for this model which is the best water filter for camping, because you can add water straight from the lake or river and drink it with peace of mind. The combination of a standard filter with fluoride removal abilities slims down the design.

The Travel Berkey is also economical.  Each filter can last for up to 6,000 gallons before replacing.  That equals about 2 cents per gallon!  It is highly recommended to replace the filters with the Berkey brand filters.

We have also included the Brita stainless steel water bottle in previous review, however, this year it was edged out by the Clearly Filtered. Perfect for on-the-go activities, the Brita stainless steel water bottle holds 32 oz of water.  Additionally, it is an eco-friendly alternative to using hundreds of single-use plastic water bottles every year.  Making the switch to a stainless steel water bottle will also save you a lot of money.  

The bottle features double-wall insulation to keep your water cold all day, and it comes with a straw and leak-proof lid.   The Brita stainless steel filtered bottle is compatible with Brita brand replacement filters.  The filter itself is BPA-Free and reduces the taste of copper, mercury, and chlorine.  Although it does not eradicate these contaminants, it makes a huge difference.  It is recommended to replace them every couple of months or after 40 gallons of use.
