Filtration Stages3-stage: activated carbon, resin, cotton

The HOOISE S15 is a 74oz (2.2L) stainless steel cat water fountain with a quiet 5V pump and metal faucet spout. Built entirely from 304 stainless steel with no seams, it resists bacterial harbor and outlasts plastic rivals.

Filtration & water quality: Three-layer activated carbon filters (carbon, resin, cotton) capture cat litter, hair, and soften water for fresher drinking. Filters require replacement every 2–3 weeks.

Key features:

  • 24-hour circulating water flow attracts pets to drink more
  • Large capacity suits multi-pet homes or week-long absences
  • Window view shows water level without opening lid
  • Mute pump designed for low noise and low-voltage safety (5V)
  • No-spill metal faucet reduces overflow and mess
  • 1-year warranty, compatible with bulk filter packs (6, 12, 20-pack options available)

Best for: Indoor cats and small dogs; pet owners prioritizing durability and stainless-steel hygiene over premium brand prestige. The quiet pump and large capacity appeal to noise-sensitive households. Cleaning requires regular filter swaps and deep pump maintenance every 2–3 weeks.
