What is the purpose of the filter in a dog water fountain?

The filter helps remove hair, food particles, dirt, and odors from your dog's water. It keeps the water fresher and cleaner for longer periods, encouraging more frequent hydration and helping to support overall health.

What type of filters do dog water fountains use?

Most dog water fountains use activated carbon filters, foam filters, or a combination of both. Carbon helps absorb odors and impurities, while foam traps larger particles like fur or food debris.

How often should I change the filter in my dog's water fountain?

Filter replacement frequency depends on the product, but a good rule of thumb is every 2–4 weeks. If you have multiple pets or notice odor or buildup, you may need to change it more often.

What maintenance is required for dog water fountain filters and pumps?

Clean the pump and fountain every 1–2 weeks to prevent buildup. Rinse filters before use, replace them as directed, and check for clogs or signs of wear. Proper maintenance helps ensure a steady flow of clean, fresh water.
