Meet the IMIPAW W03 replacement cartridge set for cat fountains. This 10-piece box brings a simple, hygienic approach to hydration for busy households. Each cartridge is individually encapsulated to shield the contents from dust and moisture, helping preserve filtration performance and giving you peace of mind as you refresh your pet’s drinking water.
The W03 cartridge uses a multilayer high-efficiency filtration system. It is designed to intercept hair and impurities, soften water, and reduce odors, while retaining minerals that many cats prefer. The result is water that can feel crisper and more inviting to drink, without claiming any medical benefits. The compact design fits cat fountains with compatible W03 cartridges and complements daily routines.
Every box contains 10 individual cartridges. They’re ready to pop into your fountain, and their sealed packaging helps maintain freshness between changes. For households with multiple cats or hard water, you may notice filtration performance remains steady when replacements occur on a tighter schedule.
Tips for optimal hydration. If your pet drinks a lot of water, or if the water quality is less consistent, you may choose to replace cartridges more frequently to sustain filtration effectiveness and water quality over time.
Q: What is included in the IMIPAW W03 cartridge package?
A: Ten individually encapsulated W03 cartridges for cat fountains.
Q: How often should I replace the cartridge?
A: Replace every 7–14 days, depending on pet count and water quality.
