Which dog water fountain do these replacements fit?

HOETEK replacement filters are compatible only with the 3.4-gallon Dog Water Fountain. They are made for that fountain rather than for water fountains generally, so match the fountain’s capacity and model before choosing this set. The 3.4-gallon capacity is the fit reference for this replacement pack.

• Designed for the 3.4-gallon Dog Water Fountain.
• Not intended as a universal replacement filter.

What does the filter system contain?

HOETEK filters use a four-layer filtration system made from activated carbon, ion exchange resin, two layers of non-woven fabric and silver ion ceramic balls. The system further filters debris in the fountain water, helping to prevent debris from causing blockages or damage. These are the filtration materials included in the filter design.

• Activated carbon and ion exchange resin.
• Two non-woven fabric layers and silver ion ceramic balls.

How do I prepare and install the replacements?

Prepare each HOETEK filter by soaking it for five minutes and rinsing it for 30 seconds, then place it in the fountain. Insert one sponge into the pump. These steps prepare the filter and position the sponge without a complicated installation process.

• Soak the filter for five minutes.
• Rinse for 30 seconds before placing it in the fountain.
• Insert the sponge into the pump.

How often should I change a filter?

Replace HOETEK filters every one to two weeks for the recommended routine. If more than one pet uses the fountain, clean the fountain and change the filter more often. The pack is presented as a six-month set, with the recommended replacement interval guiding regular changes.

• Recommended filter interval: every one to two weeks.
• Multiple-pet use calls for more frequent fountain cleaning and filter changes.

This set suits dog owners who use the compatible 3.4-gallon fountain and want replacement filters and pump sponges together, including households with large dogs or multiple pets. It is intended for that fountain specifically, with the filter schedule adjusted for multiple-pet use. For buyers whose fountain matches, the set pairs a four-layer filter design with the pump sponges needed for routine replacement.
