5687301 Air Filter Element: "Air Intake Dust Barrier" for Small Engines

The 5687301 Air Filter Element is a key air intake filtration accessory for small power equipment, designed for outdoor devices like generators and lawn mowers.

Made of high-density polyurethane sponge, its 30-50μm pore size can block sand without blocking air intake; the elastic sponge fits tightly to the air inlet, preventing unfiltered dirty air from entering; more practically, it can be washed—rinse it when dirty, dry it, and reuse it, no need to replace filters frequently.

In the use of a construction site 156F generator, after installing this filter, the dust accumulation in the engine cylinder is reduced by 70%—previously the cylinder needed cleaning once a month, now it can last 3 months; for household lawn mowers, it keeps air intake smooth while blocking grass clippings— a useful and cost-saving maintenance accessory.
