When to Change Your Pet Water Fountain Filter (And Why It Matters)
We all know how important fresh, clean water is for our pets’ health. That’s why pet water fountains like the FT666, FT007, and FT999 are a popular choice among pet owners—they encourage hydration with flowing, filtered water. But even the best waterer can’t do its job if the filter isn’t regularly replaced.
If you're using an automatic pet water fountain, understanding when and why to change the filter is key to keeping your pet healthy and your fountain working efficiently.
Why Filter Replacement Matters
Filters in pet water fountains do more than remove visible dirt—they also trap hair, debris, and microscopic impurities like chlorine and heavy metals. Over time, filters lose their effectiveness, becoming clogged or saturated with contaminants. This can lead to:
-
Unpleasant smells or tastes
-
Cloudy or discoloured water
-
Reduced water flow
-
Bacterial growth inside the fountain
Worse still, a dirty filter may stop removing harmful elements, putting your pet’s health at risk.
How Often Should You Replace Your Filter?
A general rule of thumb is to replace your pet water fountain filter every 2 to 4 weeks, depending on usage, number of pets, and water quality in your area. However, for best results:
-
Single pet use, clean water area: every 4 weeks
-
Multiple pets or heavy usage: every 2–3 weeks
-
Hot climates or hard water: every 2 weeks
If you notice reduced water flow, visible dirt, or your pet stops drinking as much, it might be time for a change—even if it hasn’t been 2 weeks yet.
