Replacement HEPA Air Filter for Karcher WD/MV series — JETtools SB9669 (fits WD3, MV3, MV2, WD3.200, WD2250)

Replacement HEPA air filter JETtools SB9669 is designed for use with Karcher wet/dry vacuum cleaners WD3, MV3, MV2, WD3.200 and WD2250. This filter provides HEPA-class fine particle filtration to capture dust, pollen and other small airborne particles produced during vacuuming, helping to maintain indoor air quality and protect the vacuum motor from dust ingress. The cartridge is intended as a service part to restore or maintain the original filtration performance of compatible machines and is sized for a straightforward fit with the listed models.

Advantages

The HEPA-grade media traps a high proportion of fine particles and allergens while allowing consistent airflow for suction performance. The filter is constructed for easy replacement and secure seating in the vacuum’s filter housing, enabling routine maintenance without special tools. Using a dedicated replacement filter helps maintain the appliance’s suction efficiency and reduces the amount of dust recirculated into the room during operation.

Suitable for

• Home cleaning where fine dust and allergens are present
• Workshops and garages with fine particulate from sanding or light debris
• Maintenance and replacement cycles to restore vacuum performance
• Wet/dry vacuuming tasks on compatible Karcher models listed in the product title

How to use

Before replacing the filter, switch off the vacuum and disconnect it from the power supply. Open the filter compartment according to the machine manufacturer’s instructions, remove the old filter and dispose of it in accordance with local regulations. Install the replacement HEPA filter into the housing, ensuring it seats correctly and any retaining clips or seals are engaged. Close the compartment and reconnect the vacuum; verify normal operation and check for any unusual noise or reduced suction which may indicate incorrect installation.

Usage recommendations

Replace the filter as part of regular maintenance or sooner if visible clogging, reduced suction or increased exhaust dust is observed. For extended filter life, remove large debris from the collection container after each use and avoid vacuuming liquids unless the filter and appliance are designed for wet use. Follow the vacuum manufacturer’s maintenance schedule and safety instructions when servicing filters.
