Nano Coated Cartridge Filter Compatible With Karcher WD 4, WD 5 M, WD 5.5 M

Nano-coated cartridge filter with its unique feature of reducing the possibility of suction power loss due to the Nano coated surface that does not allow dirt to penetrate deeply in to the surface pores. The nano-coated cartridge filter does not become clogged as fast as the commonly used standard filters as the dirt cannot penetrate as deeply into the surface pores. High dust retention ensures durability of the motor. Once Nano-coated cartridge filter is installed no additional filters are needed and can be used in wet and dry vacuum mode. Ensure the filter is at all-time intact and clean this washable filter from time to time for better performance
