WASHER INLET FILTER
A washer inlet filter (also known as a water inlet screen, valve filter, or inline sediment filter) is a small mesh or screen device installed at the water inlet of washing machines or pressure washers. It prevents debris, sediment, rust, sand, or particles from entering the appliance, protecting the inlet valve, pump, and hoses from clogs or damage. Common in both household washing machines (e.g., LG, Whirlpool) and high-pressure washers (e.g., INGCO models from your prior query), these filters are essential for maintaining water flow and extending appliance life, especially in areas with hard or unfiltered municipal water.
Based on current data, these are inexpensive, easy-to-replace parts. For pressure washers like INGCO HPWR series, they tie directly into the inlet hose setup, often as a brass or stainless steel screen. If you're troubleshooting slow fill times or low pressure, cleaning or replacing the filter is the first step.
Key Specifications (Standard for Washer Inlet Filters)
| Feature | Details |
| Material | Stainless steel mesh (50–290 mesh size), ABS plastic, or brass housing (rust-resistant preferred over steel) |
| Mesh Size | 70–200 microns (finer for household washers; coarser for high-flow pressure washers) |
| Thread/Fitting Size | 3/4" GHT (garden hose thread) or 1/2" NPT/BSP for washers; quick-connect for hoses |
| Max Flow Rate | 6–10 GPM (22–38 L/min) for household; up to 10.5 GPM for pressure washers |
| Max Pressure | 10–150 PSI (0.7–10 bar) |
| Temperature Range | 0°C to +60°C (cold water only) |
| Dimensions (Typical) | 1–2" diameter x 0.5–1" length (compact screen) |
| Pack Size | Sold in 2–20 packs for replacements |
- Types:
- Valve Screen: Fits inside the inlet valve (e.g., AGM73269501 for LG/Kenmore).
- Inline Filter: Hose-mounted (e.g., bowl-type or Y-type for pressure washers).
- Washer Filter: Simple rubber/plastic cone for garden hose inlets.
- Benefits: Reduces clogs by 80–90%, prevents valve failure, and improves efficiency. Self-cleaning designs (e.g., with bypass ports) are available for high-use setups.
- Safety Standards: NSF/ANSI 61 compliant for potable water; burst-proof up to 15 bar.
