Easy to store and easy to pour, the Culligan drinking water pitcher filter is the perfect solution for great-tasting water at an economical price. For pennies a gallon, stay hydrated with Culligan!

This is how Culligan advertises the Culligan PIT-1, a compact water pitcher filter that fits most refrigerator doors.

How compact? Exactly two quarts, although the fillable area at the top that filters water into the bottom is more like 1 quart.

Now, 1 quart is not a whole lot of water which is why we consider the PIT-1 perfect for 1-2 people but no more than that.

By the way, the unit is very cheap, even cheaper than what you pay for a Brita model. But can it also compete with the top pitchers in the market?

Culligan PIT-1 Water Filter Pitcher – Key Features

The PIT-1 was tested and certified to NSF/ANSI Standard 42 for the aesthetic reduction of chlorine taste and odor (82.8%), zinc (97.4%) and particulate class VI (>99.9%).

A certification according to Standard 53 guarantees the removal of copper (>84.0%) and mercury (>91.0%) – too bad that this pitcher is not effective against lead.

FYI: Particulate class VI includes particulates above 50 microns in size which is rather large.

Filtration speed is adequate at a flow rate of 2.5 gallons per day.

Capacity: 50 gallons or 2 months per cartridge, whichever comes first.

PIT-1 Pros

There are not too many other benefits that we can add to our list.

On the one hand, the built is pretty sturdy. And while not the highest in quality (more below), the spout cover will prevent impurities from transferring into the pitcher.

Furthermore, we have a simple integrated filter replacement indicator on the lid that reminds you when it’s time to change cartridges.

On top of that, a 2-year warranty (limited) provides cover in case anything goes wrong.

The Culligan PIT-1 – learn more on


Most of you will know how to properly use a water pitcher filter. Nevertheless, for the sake of completeness we decided to provide a quick rundown:

  • Before using the PIT-1 for the first time, wash it with warm soapy water. Rinse thoroughly afterwards. Obviously, you are not supposed to wash the filter cartridge. And please note that the pitcher is NOT dishwasher safe.
  • Push the cartridge firmly into the reservoir to create a good seal when assembling the pitcher.
  • Only ever fill the reservoir with cold tap water. At first use it may be necessary to empty the first 1-2 pitchers of filtered water to flush out any remaining carbon fines.
  • As mentioned above, you can set the filter change indicator as a reminder to replace the cartridge.
  • Try to keep the cartridge wet at all times. If it dries out it may need to re-soak before being used once again.
  • Before you can use a new cartridge, you have to soak it in clean water for approx. 15 minutes. This will flush out any loose carbon fines.

The Package (Parts)

  • Culligan PIT-1 pitcher
  • 50-gallon filter cartridge
  • Cartridge change reminder sticker


In terms of maintenance, there is only one duty that you have to remember apart from periodic cartridge replacements and that is washing all parts except the cartridge on a regular basis.

Replacement filters (Culligan PR-1, PR-1U, PR-3 or PR-3U) are not only affordable, they are also widely available online as well as offline.

PIT-1 Cons

A handful of users complained that water filtered with the PIT-1 pitcher tasted bad, really bad. It was even worse than their tap water and was often described as having a faint chemical hinge to it.

Even after rinsing a couple of gallons through the unit the taste did not improve.

One customer made the observation that the flavor seemed to be more intense the longer the water had been in contact with the filtering media – a quite unsettling thought, he remarked.

Another issue is the top, which does not always stay on when pouring. It’s also rather fragile so that it might break when dropped.

We also don’t like that the upper reservoir must be completely empty for pouring. Otherwise the holding tank pours out unfiltered water that mixes with the filtered. On a side note, this design flaw is a common issue among pitchers.

Culligan PIT-1 Review: Our Verdict + Best for

Although most customers seem satisfied with the PIT-1, the problem remains that for some the filtered water had a horrible taste.

Construction is fine, directions are easy, and we like the looks.

All in all, filtration performance is not too bad for a pitcher filter but also nothing mind-blowing to be honest. 2.5 stars!

This pitcher is best for people looking for a filter pitcher that provides basic water treatment.
