OUPUSES Dog Fountain Replacement Filters and Sponges, 16 Each for Smartoo 7L

OUPUSES replacement filters and pump sponges are made for Smartoo 7 L (236 oz / 1.8 gal) stainless steel dog water fountains, with 16 filters and 16 sponges for ongoing fountain maintenance.

• Compatible only with the Smartoo 7 L (236 oz / 1.8 gal) stainless steel dog fountain — match your fountain model before choosing these replacements.
• Five filtration components — target odors, water quality, hair, food residue and debris through separate filtering materials.
• 16 replacement filters and 16 pump sponges — keep replacement parts on hand for routine changes.
• Seasonal replacement guidance — change filters every 1–2 weeks in summer and every 2–4 weeks in winter.
• Pre-use rinse instructions — soak for 5 minutes and rinse for 30 seconds to help prevent carbon dust from entering the water.

These replacement parts are for maintaining the Smartoo stainless steel dog fountain and its filtration system. They suit households that want to refresh the fountain filter regularly, with more frequent cleaning and changes recommended when multiple pets use the fountain.

What do the five filtration components do?

The filter combines activated carbon, ion-exchange resin, non-woven fabric, silver ion ceramic balls and a built-in pump sponge. Activated carbon is intended to reduce foul odors, while the resin softens water quality. The fabric helps catch cat hair and food residue, and the ceramic balls are designed to remove harmful particles. The pump sponge filters debris to help prevent blockages and pump damage.

• Activated carbon targets unwanted odors.
• Non-woven fabric helps isolate hair and food residue.
• The built-in sponge provides another barrier for debris at the pump.

Which dog fountain do these replacements fit?

OUPUSES filters and sponges are compatible only with the Smartoo 7 L (236 oz / 1.8 gal) stainless steel dog water fountain. They are not presented as universal fountain filters, so confirm that your fountain is this specific Smartoo model before selecting them.

• Designed for the Smartoo stainless steel dog fountain.
• Use with the matching 7 L (236 oz / 1.8 gal) fountain capacity.

How should I prepare and replace a filter?

Before installing a replacement, soak it in water for 5 minutes, then rinse it under clean water for 30 seconds. This preparation helps keep activated carbon dust from falling into the fountain water. Replace filters every 1–2 weeks during summer and every 2–4 weeks during winter to maintain the filtering effect.

• Rinse with clean water after soaking.
• Clean the fountain and change its filter more often in multi-pet homes.
