HIPA 491588S Air Filter Kit for 4915885, 725ex, 625e Lawn Mowers | All-in-One Upgrade

Upgrade Your Lawn Care Air Filtration with HIPA 491588S

Meet the HIPA 491588S Air Filter Kit—the all-in-one solution built to work with multiple mower models across the 491588S/491588/725ex/625e families. The kit emphasizes robust filtration and durable construction, designed to help your mower breathe easier during routine yard work.

The main filter media uses a multi-fiber, high-density composition that aims for low flow resistance while catching a wide range of particles. In real-world terms, that means the engine can draw air more freely, while the dirt-holding capacity helps reduce how often you need to replace components. The frame uses a leak-proof polyurethane resin to help seal the filter housing and keep unfiltered air from slipping into the engine bay.

Key benefits at a glance

• 99% filtration efficiency with high-density media targets airborne particles common to lawns and dust.
• Low resistance design supports smoother airflow for potential performance gains.
• Durable frame and seal help maintain consistent filtration in variable conditions.

Upgrade quickly with the all-in-one kit approach. The package includes everything you need in one box, saving you shop trips and reducing the chance you forget a part during routine maintenance.

What’s included and fitment

• HIPA 491588S air filter
• HIPA 493537S pre-filter
• Fuel filter
• Spark plug (replaces BR6S)

Dimensions are provided to help you verify fit before you open the box: Length 5-3/16", Width 4-1/2", Height 13/16". The kit is designed to fit a range of equipment, including 491588S air filter models and 725ex/675ex/625e/625-675 series walk-behind mowers and select brands in the lawn care landscape.

Practical use in everyday yard work is where this kit shines: in dusty spring mornings, the pre-filter helps reduce debris before it reaches the core media, and the included parts allow you to perform a thorough refresh in one session. While results will vary by mower and operating conditions, users often notice easier startup and steadier engine response after a clean filter kit is installed.

Who this is for

Homeowners with multiple mower models, or shop managers seeking a convenient, bundled replacement option, may appreciate the time saved by the all-in-one kit. It’s a practical choice for regular maintenance schedules and seasonal mower care.
