Overview
['At 101oz (about 3L), the PLWF006 has one of the larger capacities in this lineup, which makes it a practical choice for homes with more than one cat, or even a small dog sharing the water source. The stainless steel construction covers the main drinking surfaces, helping cut down on the plastic taste and odor that can build up in all-plastic fountains.', "Two filters are included, and the flow is adjustable, so you can dial in a slower trickle or a stronger stream depending on what gets your cats drinking more. PETLIBRO also markets this model as quiet, which matters for a fountain that's likely to run around the clock.", 'With almost 1,900 reviews and an average of 4.6 stars, plus around 4,000 units sold monthly, the PLWF006 has one of the strongest track records of any fountain in this category.']

What buyers say
Rated 4.6 out of 5 from 1,870 reviews, with an estimated 4,000 units bought in the past month, making it one of the best-reviewed and best-selling fountains in this roundup.
With a 101oz (3L) capacity, it's well suited to two or three cats without needing a daily refill, and it's also rated for use with small dogs.
How often do the filters need replacing?
The listing includes two filters to start, and like most cat fountains, filters generally need swapping every two to four weeks depending on water hardness and how many pets are drinking from it.
What's the difference between this and PETLIBRO's PLWF005?
The PLWF006 has a larger 101oz/3L reservoir versus the PLWF005's 2.5L, plus adjustable flow and dual filters, making it the better pick for bigger households.
