Good drinking water starts with a good filter — every sip your pet takes should be filtered first. No matter how stylish the water fountain is, if the filter can’t keep up, it’s useless. The qingmushuo dedicated filter is custom-made for your pet water fountain to ensure that every drop of circulating water is clean, fresh, and irresistible for your cat or dog.
Why do you need to replace the filter regularly? Over time, ordinary bowls or fountains can accumulate hair, dust, and food residues in the water, leading to poor water quality and unpleasant smells. Even a curious cat will just sniff and walk away. The qingmushuo active water circulation filter solves this problem for you.
Four major filtering powers for visible cleanliness:
- Strong hair and debris interception — the physical filter layer effectively captures pet hair, dander, and large particles in the water, making the circulating water visibly clear.
- Activated carbon for deodorizing and chlorine removal — the high-quality activated carbon layer absorbs odors and residual chlorine, making the water sweeter and removing that tap water 'bleach taste,' even picky cats will drink more.
- Ion exchange to soften water — reduces scale and heavy metal ions, protects the pump, extends its lifespan, and makes the water gentler.
- Continuous circulating filtration — paired with the fountain’s water flow system, every drop is filtered multiple times to keep it fresh and oxygen-rich 24/7.
Replacement cycle and compatible models:
- Recommended replacement: every 2–4 weeks (depending on water quality and usage frequency)
- Compatible models: qingmushuo series electric pet water fountains (1.5L / 2.2L / other capacities)
- Packaging: individually wrapped, clean and hygienic
Easy to use, 3-second filter replacement:
1. Remove the old filter
2. Rinse the new filter with water (about 30 seconds)
3. Place it in the filter slot and reassemble 💡
Tips: Rinse the filter with water for 2–3 minutes before first use to remove any small black powder from the activated carbon (normal). After installing it in the fountain, run the machine for half an hour before letting your pet drink for best results.
Better value when bought together:
💡 Buy the fountain + filter set at the same time to save money and hassle! Filters are consumables, so it’s recommended to stock 3–6 months’ worth to avoid frequent orders and the risk of running out.
- Buy 1 filter → try it out
- Buy 3 filters → use for a whole quarter, save on shipping
- Buy 6 filters → no worries for half a year, best cost-performance
