593260 Lawn Mower Air Filter 550ex 675exi 725exi Series Engines Model and More, 798452 Air Cleaner Cartridge Filter Troy Bilt TB110 TB200 TB230 Lawnmower and More (4 Pack) Review

Overview

This is not a lawn mower itself, but a 4-pack of replacement air filters designed to fit a wide range of popular gas-powered lawn mowers, including those with 550ex, 675exi, and 725exi series engines, as well as Troy-Bilt TB110, TB200, and TB230 models. It’s the perfect solution for homeowners who want to keep their mower running smoothly without hunting for the exact OEM part or overpaying at a dealership.

Who Should Buy This

1. Homeowners with older Troy-Bilt or Craftsman mowers – If you’ve got a TB110, TB200, or TB230 that’s been running rough or struggling to start, this filter pack is a cheap first step to restoring performance.

2. DIY lawn care enthusiasts – You change your own oil, sharpen your own blades, and want to keep a spare filter on hand. This 4-pack gives you a backup for the entire season (and then some).

3. People who hate dealership markups – A single OEM filter can cost $8–12 at a small engine shop. Getting four for $9.99 means you pay less per filter than a cup of coffee.

4. Landscapers with a mixed fleet – If you maintain multiple mowers with different engines (550ex, 675exi, 725exi), this universal fit covers a lot of ground. One pack can service several machines.

Key Features Breakdown

Compatibility (550ex, 675exi, 725exi series engines, plus Troy-Bilt TB110/TB200/TB230) – This is the filter’s biggest selling point. It replaces OEM part numbers 593260 and 798452, which means it fits many Craftsman, Troy-Bilt, and Cub Cadet models. Always double-check your engine model before buying, but this covers a huge swath of the most common push mower engines on the market.

4-pack value – At $9.99, you’re getting four filters. That’s about $2.50 each. Most single OEM filters run $6–10. This pack saves you money upfront and gives you spares for future seasons or multiple mowers.

Air cleaner cartridge design – This is a foam-and-paper hybrid cartridge filter. It traps fine dust and debris better than basic foam-only filters, which is critical for engines that run in dusty conditions or near dry grass clippings. The paper element provides the fine filtration; the foam pre-filter catches larger particles.

Drop-in replacement – No modifications or adapters needed. Remove the old filter, clean the housing, and drop this one in. The dimensions match OEM specs closely, so it seats snugly without gaps.

Price point – $9.99 is aggressively low for a 4-pack of decent-quality air filters. Even if you replace filters twice a season, this pack covers two years for most homeowners.

Pros

1. Cost-effective – At $2.50 per filter, this is the cheapest way to keep your mower breathing clean air. You’ll pay less for four of these than for one OEM filter.

2. Broad compatibility – Fits multiple engine series and Troy-Bilt models. If you own more than one compatible mower, this pack is a no-brainer.

3. Solid build quality – The foam pre-filter is dense enough to catch grass and debris, while the paper element is pleated properly for good airflow. It’s not flimsy.

4. Easy installation – No tools required. Pop open the air filter cover, swap the old one, close it up. Five minutes max.

5. Includes spares – Having three backup filters means you’ll never be caught without a clean one mid-season. That’s a real convenience when you’re trying to finish mowing before a storm.

6. Good seal – The foam perimeter fits tightly against the air filter housing, preventing unfiltered air from bypassing the filter. That’s a common issue with cheap knockoffs.

Cons

1. Not OEM – If you’re a stickler for brand-name parts, these are aftermarket. The paper element feels slightly thinner than some OEM filters I’ve tested. It still works, but it may not last as long in extremely dusty conditions.

2. Fit can be tight on some models – A few users report that the filter is a hair too thick or too wide for certain housings. It usually seals fine, but you may need to press it in firmly. Not a dealbreaker, but worth noting.

3. No pre-oil instructions – Some foam pre-filters benefit from a light coating of air filter oil for better dust trapping. This foam is dry. It’s fine for most residential mowing, but if you cut in very dry, dusty conditions, you might want to oil it yourself.

4. Packaging is basic – The filters come in a plain plastic bag. They’re clean and undamaged, but don’t expect retail packaging. This is a budget product, and the presentation reflects that.

Bottom Line

If you own a mower with a 550ex, 675exi, or 725exi series engine—or a Troy-Bilt TB110, TB200, or TB230—this 4-pack of air filters is an exceptional value. For $9.99, you get four filters that cost less than a single OEM replacement. They fit well, seal properly, and will keep your engine running clean for multiple seasons. The only real trade-off is that they’re not OEM, so the paper element might not last as long in heavy dust, but for typical suburban lawn mowing, they’re more than adequate. I recommend buying a pack now and swapping filters twice a year (spring and mid-season) for optimal performance. Your mower will start easier, run smoother, and last longer.

Frequently Asked Questions

Q: Will this filter fit my Craftsman mower with a 550ex engine?
A: Yes, it should. The 550ex series is one of the primary compatible engines. Just confirm your engine model number (usually stamped on the engine shroud or near the spark plug) matches 550ex, 675exi, or 725exi. For Troy-Bilt models, it fits TB110, TB200, and TB230.

Q: How often should I replace this air filter?
A: For most homeowners mowing a standard lawn every week, replace it once per season or every 25 hours of use. If you mow in dusty conditions or when the grass is dry and clippings are flying, check it every 10 hours and replace if it looks dirty. The 4-pack means you can afford to change it more often.

Q: Is this filter washable and reusable?
A: No. This is a disposable paper-and-foam cartridge filter. Do not wash it—water will damage the paper element and cause it to tear or collapse. Just replace it when it’s dirty
