Compatible Cat Fountain: The replacement filters are compatible with the PETLIBRO Dockstream RFID Smart Cat Water Fountain PLWF305.
In the Box: The package includes 8 packs of replacement filters and 8 packs of replacement foam filters. To ensure a better user experience, the cat fountain filter and foam filter are individually packaged.
All for Your Pet’s Health: Every drop of water is filtered through a 4-layer filtration system to remove impurities and provide oxygen-enriched, better-tasting water.
Vertical Filtration System: 1. Activated carbon eliminates foul odors. 2. Ion exchange resin removes heavy metal ions and softens water quality. 3. The non-woven fabric captures cats’ hair and impurities. 4. The built-in foam filter further filters debris to prevent blockages and damage.
For Optimal Use – Soak the filter for 5 minutes and rinse for 30 seconds before use. To maintain the filtering effect, it is recommended to replace the filters every 2 weeks. If you have multiple pets, it is advisable to clean the fountain and change the filter more often.

A great choice for any Cat Owner
Much better than my last cat fountain. Notifies me when they drink and when the filter needs to be changed. It is a great choice for my cats!

We buy the the real ones
In other cat fountains, we have bought off label refill filters. Well this fountain was considerably more so at the outset we bought a set of filters. They are packaged well, keep the fountain clean and flowing and even include a tiny brush for cleaning. However, these models require changing out biweekly. We kind of expect this anyway with a Siberian cat so it doesn’t bother us.Oh! And they also prefer bottled water but not distilled. We use bottled anyway because our municipal is terrible and the reason we decided to spend more on a smart one was the cheap ones burn out within a year.

Poor quality replacements from Same company
Purchased these replacement filters, for the pet Libro fountain I purchased in April. Pet Libro has a sponsored site on Amazon which I ordered the filters from. When I receive them as you can see in the picture, the filters are quite different. The filter on the right came with the fountain originally, and the filter on the left was a part of the replacement pack. I reached out to pet Libro company and they told me that I purchased the filters from an unauthorized site. It was an Amazon site and when you click on the pet Libro store it comes up with the pet Libro site. Amazon was not really able to help me. I returned the filters, but I’m stuck with this fountain. I’ll use as a planter, because I refuse to do business with this company

RFID filter
Compatible with the RFID smart fountain PLWF305 system. 8 pack . Filters system really well , one of my 5 cats threw up and the filter kept it from flowing in water .

These black sponges work ONLY for RFID version
Reviews saying the black sponges are poor quality and/or too small are incorrect—they chose the wrong replacement filter set. The white filter is the same for all the PETLIBRO docking fountains, but the black sponges (prefilters) in this pack are for ONLY the RFID version. If you have the RFID one, these filters are exactly what you need.Last year I mistakenly got filter sets for the non-RFID versions and the sponge was larger and more dense, making it impossible for the filter to pull enough water through.PETLIBRO really dropped the ball by making the white replacement filters interchangeable between the fountains, but not the black-sponge prefilters. It’s tough to really tell which black sponge is in the picture without pulling out a ruler. This has led to many unhappy customers bc they don’t have the actual replacement they need. (Knockoff versions claim their sets are compatible with the RFID version, but I assure you the larger black sponges will not work.)If you have the RFID dockstream, you MUST use these smaller, less-dense, black sponges as your prefilter replacements.

Does its job
I really like these refill packs for my petlibro fountain. It works and it’s super easy to install. It fits my PLWF115 model and it works as intended. Make sure to soak it in hot water for 5 minutes before use. Sometimes it turns the water a little dark if it is not properly cleaned.
