## Long description

Replacement HEPA air filter compatible with KARCHER WD4, WD5 and WD6 wet & dry vacuum cleaners. The JETtools SB9591 HEPA element is designed to capture fine dust, allergens and small particles that regular filters may miss, helping to maintain cleaner exhaust air during wet and dry vacuuming. Intended for routine maintenance and performance restoration, this HEPA filter is suitable for both household cleaning tasks and workshop environments where fine particle control is required.
Advantages
The HEPA filter media provides high-efficiency particle retention, reducing airborne dust and improving indoor air quality emitted from compatible KARCHER wet & dry vacuums. Its form factor and sealing surfaces are engineered for straightforward replacement, restoring suction performance and filtration efficiency when the original filter is worn or clogged. Constructed to withstand typical workshop dust and domestic debris, the filter supports continued reliable operation of the vacuum cleaner when installed and maintained as recommended.
Suitable for
Household wet and dry vacuum cleaning where fine dust and allergen capture is needed
Workshops and garages with sawdust, metal shavings or fine particulate debris
Periodic maintenance and filter replacement to restore vacuum performance
Allergy-sensitive environments requiring improved exhaust air cleanliness
Key specifications
Filter type: HEPA-class high-efficiency particulate filter
Compatibility: designed for KARCHER WD4, WD5 and WD6 wet & dry vacuum cleaner models
Material: pleated filter media with supportive frame and sealing gasket
Filtration target: fine dust, allergens and small particulate debris
Application: suitable for both wet and dry vacuuming tasks when used according to manufacturer guidance
How to use
Turn off and unplug the vacuum cleaner before attempting any filter replacement. Open the vacuum housing according to the vacuum cleaner manufacturer’s instructions, remove the used filter and dispose of it following local waste regulations. Install the replacement HEPA filter by seating it correctly in the filter compartment and ensuring the sealing gasket aligns with the housing to prevent bypass. Reassemble the housing, reconnect power and verify normal operation. Replace the filter at intervals recommended by the vacuum cleaner manufacturer or sooner when heavily soiled.
Usage recommendations
Inspect the filter regularly under typical working conditions and replace it if airflow or suction decreases, or if visible contamination is present. Avoid using the filter as a primary barrier for excessive liquid uptake; drain large volumes of liquid from the vacuum tank before relying on the filter. Store unused filters in a dry place away from direct sunlight to preserve media integrity.
