Keep Debris Out of Your Aerator Pump
The T-H Marine Aerator Filter Dome is a two-piece pre-filter that mounts in front of your aerator pump intake or behind a standard thru-hull fitting to block debris before it reaches the pump. It's a simple, tool-free addition that extends pump life and keeps your live well water clean — especially important when fishing in weedy, silty, or debris-heavy water.
The dome design creates a large filter surface area relative to its footprint, so flow stays strong even as the screen collects material. The twist-lock assembly means you can pull it off for a quick rinse and snap it back on in seconds — no tools, no fasteners.
- 1" hole ID dome fits 3/4" thru-hull fittings and aerator pump snouts
- Two-piece twist-lock design — no fasteners, no tools required
- Mounts under a thru-hull flange or directly over a pump snout
- Also works as a debris screen on overflow drain openings
- Large dome surface maintains strong flow even when partially fouled
- Easy to remove and rinse clean in seconds
Parts Desk Insights
Best use case: This filter dome earns its keep on boats fishing in lakes or rivers with heavy weed growth, algae, or fine silt — conditions where an unprotected pump intake will clog or wear out fast. It's also a smart addition any time you're running a pump in shallow water where bottom sediment gets stirred up. Fit it once and you'll spend far less time clearing blocked pump intakes mid-trip. It doubles as a coarse screen on overflow drain openings, which is a handy secondary use if you have a spare.
Compatibility: Fits 3/4" thru-hull fittings and aerator pump snouts with a 1" hole ID. For intake protection on the pump itself, also consider the T-H Marine Stainless Steel Wire Mesh Strainer for a metal-screen alternative.
