Anti-Odor Floor Drain Core Strainer with One-Way Valve
Keep Your Bathroom Fresh & Drain-Clog-Free
Say goodbye to unpleasant odors, blocked drains, and unwanted pests creeping up from the sewer. This Anti-Odor Floor Drain Core Strainer is an all-in-one replacement insert for bathroom, kitchen, balcony, and laundry room floor drains. Engineered with a multi-layer ABS and PC construction plus an elastic rubber seal, it installs in seconds — no drilling, no tools, no professional required.
Key Features
- Clog-Proof Perforated Strainer: The dense-perforated ABS top strainer captures hair, food scraps, and solid debris before they enter the drain pipe, preventing blockages and cutting down on cleaning time.
- One-Way Odor Isolation Valve: A gravity-driven PC flap valve opens automatically when water flows through and seals tightly the moment drainage stops — effectively blocking sewer gases, cockroaches, and other small insects from entering your living space.
- Leak-Proof Sealing Ring: The built-in soft elastic rubber gasket forms a snug fit against the inner wall of your existing floor drain, eliminating gaps that allow water to seep around the edges and keeping your floor dry.
- Universal Adjustable Adaptor: The multi-layer stepped outer rim is compatible with most standard round floor drain openings — no extra drilling or modification needed. Ideal for both new installations and old drain renovations.
- Easy Maintenance Design: All internal parts are fully detachable. Simply lift the entire core out of the drain in seconds for a quick rinse under running water — no tools, no hassle, long-lasting performance.

Frequently Asked Questions
Q: What drain sizes is this floor drain core strainer compatible with?
A: This drain core features a multi-layer stepped outer rim designed to fit most standard round floor drain openings. The universal adaptor design means no drilling or modification is required for the majority of common bathroom, kitchen, and laundry room drain sizes.
Q: How does the one-way valve prevent odors from coming up through the drain?
A: The gravity-driven PC flap valve at the base of the drain core opens automatically when water flows through, allowing normal drainage. As soon as the water flow stops, the flap seals shut under its own weight, creating an airtight barrier that blocks sewer gases and insects from travelling back up through the pipe into your room.
Q: How do I clean and maintain this floor drain strainer insert?
A: Maintenance is very simple. All components are detachable — just lift the entire drain core out of the floor drain opening (no tools needed), separate the parts, rinse them under running water to remove any trapped debris, reassemble, and reinsert. Regular rinsing keeps drainage efficiency at its best.
Q: Is this drain insert safe to use in my home?
A: Yes. The drain core is made from ABS and PC plastics along with an elastic rubber sealing gasket — materials that are widely used in household plumbing accessories. The product has been tested to contain no high-concern chemicals, making it suitable for everyday use in bathrooms, kitchens, and other areas of the home.
