5 Pack 698369 Foam Air Filter Replace for BS 698369 4216 5088 5099 5086K 5088H MTD 490-200-0011 Craftsman SPA8S1062853001 Fits 9B902, 98902, 98982, 10A902, 10B902, 10A982 Engines

What It Is

This is a 5-pack of foam air filters designed for small engines, primarily on walk-behind mowers, tractors, and pressure washers. They replace the OEM Briggs & Stratton 698369 filter and fit many 500-series engines (e.g., 9B902, 98902, 98982, 10A902, 10B902, 10A982) as well as compatible Craftsman and MTD models.

Fitment & Compatibility

Before buying, verify your engine model number (stamped on the blower housing or valve cover). These filters fit:

• Briggs & Stratton: 698369, 4216, 5088, 5099, 5086K, 5088H
• MTD: 490-200-0011
• Craftsman: SPA8S1062853001
• Engine series: 9B902, 98902, 98982, 10A902, 10B902, 10A982

Measure your old filter: the foam element is roughly 4.5" x 3.5" x 1.5" (height varies slightly). Do not rely on brand name alone—check the engine model, not just mower deck size. If your engine uses a paper filter or a different shape, this won’t work.

Key Things to Know

• Quality: These are foam, not paper. Foam traps dirt in its pores and can be washed and reused, but they’re less dust-efficient than paper. Fine for residential mowing on clean lawns; avoid for heavy dust or dry conditions.
• Installation: Dead simple—remove old filter, slide new one onto the stud or into the housing, and secure with the retainer. No tools needed.
• Common gotcha: The foam is pre-oiled from the factory, but it’s light. For best dust capture, apply a thin coat of foam filter oil or clean engine oil and squeeze out excess. Running it dry lets fine dust pass through.
• Pack value: 5 filters at ~$1.68 each is cheap. If you change filters every season, this pack lasts years for one mower.

Should You Buy It

Yes, if you have a compatible Briggs & Stratton or Craftsman engine (verify the model number) and want a low-cost, no-hassle way to keep your mower breathing clean. The foam design is fine for typical lawn use, but if you mow in very dusty conditions or want maximum filtration, stick with a paper filter. For the price, it’s a solid value.
