Key Features

• 【Wide Compatibility】As a professional replacement filter, it fits most countertop gravity water filter buckets. Compatible with Berlkey (Travel, Light, Big, Royal, Imperial, Crown), ProOne+, Waterdrop (countertop gravity series). No modifications needed—simply remove the old filter and install the new one easily. It fits the original bucket perfectly to prevent leakage and ensure stable filtration.
• 【Superior Filtration Performance】Our replacement activated carbon rod filter has a 3-stage filtration (high-density activated carbon, silver ions, precision ultrafiltration membrane) for deep purification. Activated carbon adsorbs chlorine, sediment, rust and odors; ultrafiltration blocks tiny impurities ordinary filters can’t, ensuring clean, safe water.
• 【Long-Lasting Durability】Each pair of filters lasts up to 6,000 gallons (actual life varies slightly by water quality). Proper pre-use cleaning extends life: backwash under faucet for 1 minute first to remove loose carbon dust.
• 【Versatile for All Water Purification Needs】Suitable for filter replacement in daily home use (kitchen, water dispenser), outdoor activities (camping, hiking, RV travel) and emergencies (natural disasters, field work). It adapts to most water sources (tap, lake, river, stream, pond, rain) for safe drinking water anytime, meeting both daily and outdoor spare needs.
• 【Professional After-Sales Guarantee for Worry-Free Purchase】We offer a long-term quality guarantee. If you have issues like model mismatch, abnormal filtration or quality defects, contact us immediately—we provide after-sales service within 24 hours.
