The main purpose of water filter pitchers should be to improve the taste of drinking water while removing as many contaminants as possible from it. Unfortunately, most pitchers only meet the first half of this premise: They neutralize bad tastes and odors quite well, but they don’t do much to protect your and your family from the vast majority of potentially harmful heavy metals and chemicals etc. that might be present in your water supply.

In this brief guide, we’re going to compare a few of the most popular water filter pitchers to what we consider the most effective model. Hint: As you’re about to learn soon, the latter clearly stands out from the others in regards to the total number of contaminants it has shown to remove, making it our favorite unit by far. So without further ado…

The following table compares the key figures of 3 popular pitcher water filters (Brita, PUR, ZeroWater) with one lesser-known brand: Clearly Filtered.

“-” means not tested

As anyone can easily tell, the Clearly Filtered water filter pitcher is tested according to various NSF standards to remove a total number of approx. 230 water contaminants, whereas the Brita Longlast reduces no more than 12, the PUR Lead-Reducing pitcher filter removes 13, and even the hyped ZeroWater pitcher filter only removes 23.

The listed contaminants with their specific reduction rates are only an excerpt of all testing data and shall give you an idea of the removal capacities of each pitcher and, in case of Brita, PUR, and ZeroWater, what they’re missing. We’ve tried to keep the list short and concise, only including some of the most common respectively most harmful pollutants that can be found in our water supplies today.

For transparency, we also wanted to mention that while the Clearly Filtered pitcher has been tested by an independent and accredited laboratory in a controlled environment according to NSF (EPA) standards, it’s not actually NSF-certified as far as we can tell.

Still, all contaminants were reduced to permissible limits as set by NSF. And in case you’re interested you can check out the actual testing laboratory Envirotek Laboratories (EPA-ID#: NJ01298).

Further Pros & Cons of the Clearly Filtered Pitcher

Apart from removing more contaminants that any other water filter pitcher on the market today, what other benefits (and drawbacks) does the Clearly Filtered have?

Pros

  1. It’s built in the USA.
  2. The pitcher is super easy to put together. It only takes a few minutes.
  3. It can hold up to 10 cups of water, enough for family use.
  4. The removable lid allows for easy refilling.
  5. Healthy minerals are kept in the water and will add to your daily nutritional intake.
  6. One filter cartridge provides 100 gallons of filtered water on average (around 4 months) – much more than what you get with most of the competition. Thus, you don’t have to worry about frequent filter replacements.
  7. The pitcher material is medical-grade Tritan plastic. 100% BPA-free.
  8. There’s a 30-day money-back guarantee. It allows you to try the pitcher risk-free. If you’re not satisfied, simply send it back and you’ll receive a full refund.
  9. Lastly, the Clearly Filtered pitcher is warranted for lifetime.

Cons

  • Replacement filters are quite expensive: $50 per cartridge. Although, you can save up to $9.5 if you buy in bulk and subscribe to get filters automatically delivered on schedule.
  • Some people said their filters don’t last as long as advertised and complained about slow flow. We never had any issues with this.

In Conclusion

Bottom line, if you want the water filter pitcher that removes the most contaminants, get the Clearly Filtered. From a water quality perspective, it’s hands down the best product on the market right now.
