Premium Faucet Aerator Flow Restrictor Replacement Insert for Water Conservation
Premium Faucet Aerator Flow Restrictor Replacement Insert (M21.5)
Upgrade your bathroom and kitchen faucets with a high-performance aerator insert that conserves water, reduces splash, and improves water quality — all with a fast, tool-free installation.
Product Overview
Our Premium Faucet Aerator Flow Restrictor (M21.5) is designed for homeowners and property managers who want to reduce water consumption without sacrificing the feel of a strong stream. The anti-splash aeration design produces a smooth, uniform flow while the fine mesh screen traps sediments for cleaner output.
Why choose this aerator?
- Water-saving technology: Reduces flow volume to lower utility bills while maintaining perceived pressure.
- Anti-splash performance: Produces a controlled, aerated stream that minimizes splashing around sinks.
- Built to last: ABS plastic core and high-quality silicone gaskets deliver a leak-proof, durable seal.
- Improved water quality: Fine mesh filter captures debris and sediment.
- Fast installation: Screw-in M21.5 insert fits most M22 and M24 housings — install in minutes.
Applications
Ideal for kitchen and bathroom faucets in homes, apartments, rental properties, offices, and renovation projects. Works well on both male and female threaded faucet housings when used with the correct adapter (if needed).

Quick & Simple Installation Guide
- Remove old aerator: Unscrew the existing aerator from the faucet spout. Use a cloth and pliers if it’s tight to avoid scratching the finish.
- Inspect housing: Clean the faucet threads and remove any sediment or old gasket material.
- Insert new M21.5 core: Place the new flow restrictor into the aerator housing. If your faucet uses a different thread (M22/M24), use the appropriate adapter or check fit.
- Reattach housing: Screw the assembly back onto the faucet head and hand-tighten. Check for leaks and tighten slightly with pliers wrapped in cloth if needed.
- Test: Turn on the water to verify stream pattern and check for drips. If splashing or leaking occurs, remove and re-seat the gasket.
Maintenance & Care
To keep performance optimal, remove and clean the fine mesh filter every 1–3 months depending on local water quality. Soak in vinegar for mineral deposits, rinse, and re-install. Replace the insert if the mesh is damaged or if leaks persist.
Frequently Asked Questions (FAQ)
Will this aerator reduce my water pressure?
No — the M21.5 flow restrictor is engineered to reduce water volume while preserving perceived pressure with aeration, so everyday tasks feel normal but use less water.
Does it fit my faucet?
It fits most standard M22 and M24 male and female housings. If your faucet has a different thread size, an inexpensive adapter is usually available. Check the faucet spout or measure the thread diameter to confirm.
How much water can I save?
Savings vary by model and local usage patterns, but typical flow restrictor aerators reduce flow by 20–60% compared to older high-flow aerators. Savings show up quickly on monthly utility bills.
Technical Notes & Compatibility Tips
- If your faucet thread is recessed or unusually shaped, remove the outer housing and insert the M21.5 core directly into the housing before re-attaching.
- Some European or specialty faucets use non-standard dimensions — measure thread diameter (in mm) to confirm compatibility.
- When in doubt, take a photo of your faucet spout and share it with the seller or support team for fast compatibility confirmation.
