Regular replacement helps prevent build-up of impurities and ensures that your pet's water is always fresh and clean.[Preparation Tips for Optimal Use]For best results, we recommend soaking the new filter in water for 5 minutes and rinsing it thoroughly for before installation. This pre-use preparation helps activate the filter media, ensuring effective filtration from the first use.Specification:B:6PCSColour:WhiteMaterial:plasticPackage Contents:6 x FilterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
