What It Is

This is a two-piece air filter set (590825 air filter plus 594201/796031 pre-filter) designed for Briggs & Stratton single-cylinder engines found on riding mowers and zero-turn models. It replaces OEM parts MIU14395 and MIU13038.

Fitment & Compatibility

• Fits: John Deere D100, D110, D125, D130 series; Husqvarna YTA24V48, YTH18542, YTH24V48, YTH24V54, YTH22V46; plus many Craftsman, Poulan, and Murray riders using the same B&S engine.
• Check before buying: Measure your current air filter housing. The main filter is roughly 4.5" x 3" x 2.5" (oval). The pre-filter is a foam wrap that slides over it. If your mower uses a different shape (round or rectangular), this won’t fit. Confirm your engine model number from the valve cover or shroud—this works with B&S 31C707, 31P777, 33R877, and similar single-cylinder engines.
• OEM vs aftermarket: This is an aftermarket set. It’s not made by John Deere or B&S, but dimensions match OEM. Some users report slightly thinner foam on the pre-filter—still functional for dust and grass clippings.

Key Things to Know

• Quality: Dense paper filter with a snug fit. Foam pre-filter catches larger debris, extending main filter life. Washable pre-filter (rinse with mild soap, dry completely before re-oiling lightly).
• Installation: Tool-free—slide old filter out, remove pre-filter, install new pre-filter over main filter, snap housing closed. Takes 2 minutes.
• Common gotcha: The pre-filter can shift during installation. Make sure it’s fully seated and not bunched up—otherwise air bypasses it. Check every 25 hours of use.
• Replacement interval: Replace main filter annually or every 100 hours (sooner in dusty conditions). Clean pre-filter every 25 hours.

Should You Buy It

Get this if you own one of the listed John Deere or Husqvarna riders and want a budget-friendly replacement that works as well as OEM for normal residential cutting. It’s not for commercial use or heavy dust—go OEM if you cut in extreme conditions. At under $10, it’s a solid value for routine maintenance.
