Before You Buy
Key Buying Factors
01
Material Quality
Stainless steel is preferred for durability and hygiene. Plastic may be lighter but can retain odors and scratches.
02
Filtration System
Multi-stage filters (sponge, carbon, ion-exchange) remove impurities and improve taste. Consider filter cost and availability.
03
Noise Level
Pump noise varies. Larger pumps tend to be louder. Look for ultra-quiet pumps, especially for bedrooms.
04
Capacity
Larger tanks (2L+) require less frequent refills but are heavier. Choose based on pet count and your schedule.
05
Power Source
Wireless battery-operated fountains offer placement flexibility but need recharging. Corded models are consistent but limit placement.
06
Ease of Cleaning
Models with smooth surfaces and dishwasher-safe parts save time. Avoid complex designs with hard-to-reach corners.
Living With It
Care, Cost and Maintenance
Daily Maintenance
Check water level daily. Rinse the fountain top and replace water every 1-2 days to prevent slime.
Weekly Cleaning
Disassemble and wash all parts with mild soap and water. Use a soft brush to clean the pump and tubing.
Filter Replacement
Replace filters every 2-4 weeks depending on usage and water quality. Some fountains have indicator lights or remind you.
Pro tip
Place the fountain away from food bowls to reduce debris in the water. Also, position it on a mat to catch any splashes and protect floors.
Frequently asked questions
How often should I clean my pet fountain?
We recommend a full disassembly and cleaning every week to prevent bacteria buildup.
Can I use the fountain without a filter?
It is not recommended as filters remove impurities and reduce noise. The pump may also get clogged without filter.
Why is my fountain making noise?
Low water level or air bubbles in the pump are common causes. Refill the tank and ensure the pump is fully submerged.
How long does the battery last on wireless models?
Battery life varies, typically 15-30 days on a full charge depending on usage and size.
Are stainless steel fountains better for cats?
Yes, stainless steel is non-porous and resists bacteria, reducing the risk of chin acne. It is also more durable.
