Performance That Matters
Unmatched Filtration Efficiency
The Culligan P5A P5’s 5-micron rating is an impressive aspect, particularly for those relying on city and well water supplies. A lower micron rating means a finer filtration—capturing more of the minute particles that can contaminate your water supply. With this filter, even the tiniest rust and sediment particles are caught, leaving your water as pure as can be.
Optimal Flow Rate
The recommended flow rate of 4 gallons per minute ensures you don’t have to compromise on water pressure across your home. Whether you’re taking a shower, washing dishes, or watering your garden, the flow remains steady and reliable, making this filter both practical and efficient for everyday use.

How Long Does the Culligan P5A P5 Last?
Longevity Depending on Usage
With a life of up to 8,000 gallons or about 2 months, your Culligan water filter is designed for longevity. Of course, the actual lifespan can vary depending on the typical water usage in your home and the water conditions in your area. This duration ensures that you’re not constantly needing to replace filters, making it a cost-effective option in the long run.
Easy Replacement Reminder
To make maintenance a breeze, Culligan provides a change reminder sticker. This little addition makes it easier for you to remember when it’s time to swap out the filter for a new one, ensuring your water filtration remains top-notch without needing to guess or remember the last change.
