Pawaii Wireless Cat Water Fountain Replacement Filters, 6 Pack Replacement Filters for 68oz/2L Automatic Pet Fountain Cat Water Fountain, NSF

I'm a Vine reviewer, so have had a chance to test and review several cat fountains including Pawaii, no-name made-in-China generic stuff, and one made by Petlibro (a leading automated pet feeder manufacturer). NONE of these hydration systems except Pawaii comes with very stringent NSF certification (Pawaii is owned by Waterdrop which manufactures human water filters and reverse osmosis systems). This is not a Vine review; I paid for these filters. Sure, the marketers of competing non-NSF systems espouse "ultra" filtering and other flowery words, but never provide any proof of performance. By the way, the basic non-WiFi $35.99 fountain is excellent. Very little noise except for the babbling brook of water that starts up when an animal walks by it, which encourages cats to drink; many cats don't drink enough water if they eat only kibble. Less tech to potentially fail and eat battery power. Easy to clean and change the filter. I rated it 5 stars. Some others, like the Petlibro, have very loud motors that can scare some cats; the Petlibro filters are much more expensive and harder to change. Other filters for generic fountains are often useless. My rating system: 5 Stars = Knocks it out of the park. A great value! 4 Stars = Excellent product. A solid buy. 3 Stars = It provides some value, but perhaps not as advertised. 2 Stars = A little dubious, so do your research. Read the critical reviews! 1 Star = Avoid this product and look elsewhere.

Quality filter for your pets. Keeps water fresh and filters out hair and other debris. Easy to replace

Great water fountain. Filters get changed once a month. Love the automatic delivery . Company has been excellent to work with.

I change the filter monthly as suggested and pried open the filter to see the contents inside. I was surprised to find only two small bags of activated carbon. There's also a gel pouch, likely for ion exchange to soften the water, and sponges to filter out debris. After a month, the pictures show significant dirt accumulation. It seems to filter debris effectively and has more contents than competitor products, but other than that I'm not sure if it's a good filter overall.

To be honest, this is the best fountain (and filters) you can find. I’ve struggled in the past for my rabbit to get to drink his water from the bowl, but this is not a problem anymore with this fountain and filters. The water is always clean, they are so easy to clean each week and you just need to change it every month, and no worries, the fountain will show you an indicator light in yellow to let you know you should replace it!
