How do you choose the best water filter system that removes chemicals, medicines, bacteria, and more? There are a lot of water filters out there, but only one of them actually purifies your tap water.
A zillion years ago, we got a Brita water filter pitcher as a wedding present. It was quite the cool thing at the time. We thought it was neat, but eventually we got tired of spending money on replacement filters. We figured the city water coming from the tap was just fine, right?
What I’ve learned since then is that there’s a big difference between tap water, filtered water, and purified water. (We won’t even discuss bottled water, since that’s usually just tap water that you pay through the nose for.)
Is Your Tap Water Clean?
Tap water (city water) is treated with chlorine and other chemicals to remove waterborne diseases. Your tap water could also could contain bacteria, viruses, lead, Roundup, and more.
You can look up your water quality using Environmental Working Group’s Tap water database. Be warned, though–you might not like what you read.
Yes, there are federal requirements for water quality. However, as we’ve seen from the conditions in Flint, Michigan, these are not always maintained.
Is Filtered Water Better?
There is no federal regulation for water filters like Brita or PUR, although I’d argue that a federal regulation doesn’t mean much (see: Flint, Michigan). There are certain voluntary standards (ANSI standards) that companies agree to meet, though.
What does a water filter do? They remove most bacteria, lead, and chemicals. They also remove the chlorine that’s used to treat tap water, as well as any particulates that cause water to have taste or odor (eeeew).
Why is Purified Water Best?
There’s an important distinction between filtered water and purified water.
A water purifier has to meet all of the ANSI standards for filtered water plus it must:
- Remove at least 99.9999% of pathogenic bacteria
- Reduce viruses by 99.99%
This qualifies it to be a water purification system instead of simply a water filter.
I don’t know about you, but those stats look pretty amazing to me. I don’t want to drink water with viruses in it!
How do I Get Purified Water?
The best way to get purified water is with a system specifically designed to purify (not just filter). We don’t have the plumbing know-how to install something for the whole house, so I chose a Berkey water purifier for our family. (Photo credit)
The Berkey uses microfiltration with six different media types, adsorbtion, and ion exchange to make sure your water is absolutely clean and pure.
This is a partial list of the rotten stuff that a Berkey removes from your water:
- Viruses: Removed to >99.999% (exceeds purification standards)
- Pathogenic Bacteria (and Surrogates): Removed to >99.9999% (exceeds purification standards)
- Trihalomethanes: Removed to >99.8% (below lab-detectable limits)
- Inorganic Minerals (including chlorine): Removed to below lab-detectable limits
- Micro-Organisms (including e.Coli): Removed to >99.9%
- Pharmaceutical Drug Contaminants: Removed to >99.9%
- Pesticides & Volatile Organic Compounds: Removed to below lab-detectable limits

How Does a Berkey Work?
The Berkey is really easy to use. It’s gravity-fed and doesn’t use electricity (great for RV-ers or camping). It sits on the kitchen counter and we use it for drinking water and cooking water. Each night, I refill it and the water goes through the filters overnight so it’s ready in the morning.
There are several sizes and we have the Travel Berkey. I secretly have Berkey envy for my friend Lisa’s Big Berkey (you know her from Farmhouse on Boone)…or maybe I just envy her entire kitchen. Isn’t it gorgeous?
