2Pack Air Filter 593260 798452 334404 Air Cleaner Cartridge Filter, Lawn Mower Air Cleaner Replacement Filters for 4247 5432 5432k 09P00 09P702 500EX 550EX 575EX 625EX 675EXI 725EXI Series Engine Review

Overview

This isn’t a lawn mower—it’s a two-pack of replacement air filters designed to keep your mower’s engine breathing clean. The 2Pack Air Filter 593260 798452 334404 is a budget-friendly, high-quality air cleaner cartridge for popular Briggs & Stratton engines in the 4247, 5432, 5432k, 09P00, 09P702, 500EX, 550EX, 575EX, 625EX, 675EXI, and 725EXI series. At $5.99 for two filters, it’s aimed at homeowners and DIY mechanics who want to extend the life of their mower without overpaying for OEM parts. If you own a walk-behind mower, tractor, or pressure washer with one of these engines, this is a no-brainer replacement.

Who Should Buy This

• Homeowners with a single mower – If you have a 1/4 to 1/2 acre lawn and use a push mower with a Briggs & Stratton 500EX or 550EX, you’ll go through one filter a season. This two-pack covers two years for pocket change.
• DIYers who maintain multiple small engines – Got a mower, a pressure washer, and a log splitter all using similar engines? This pack lets you stock up and swap filters on schedule without hunting for parts.
• Budget-conscious buyers who refuse to pay dealer prices – OEM filters from Briggs can run $8–$12 each. This pack gives you two for less than the price of one, with the same fit and function.
• Anyone who’s tired of clogged filters causing hard starts – If your mower sputters or stalls after a dusty season, replacing the air filter is the cheapest fix. This pack makes it easy to stay ahead.

Key Features Breakdown

• Compatibility with 16+ engine models – Covers 4247, 5432, 5432k, 09P00, 09P702, 500EX, 550EX, 575EX, 625EX, 675EXI, 725EXI, and more. This is a wide net—just double-check your engine’s model number before ordering.
• Two filters per pack – At $5.99, you get a spare. That’s smart because you’ll forget to order the second one until your mower starts coughing in July.
• Paper pleated media – Standard but effective. This filter traps fine dust and grass debris without restricting airflow until it’s fully clogged. It’s not washable, but at this price, you just toss it.
• Pre-formed foam seal – The gasket around the edge is dense and flexible, creating a tight seal against the air cleaner housing. A poor seal lets unfiltered air in, which kills engine rings. This one seals well.
• Direct replacement for 593260, 798452, 334404 – These are the common OEM part numbers. If you’ve bought one of those before, this is a drop-in swap with no modifications.

Pros

1. Price is unbeatable – $5.99 for two filters is roughly half the cost of a single OEM filter. You save money and get a backup.
2. Wide engine compatibility – Works with dozens of Briggs & Stratton engines from the 500EX to the 725EXI. That covers most residential mowers from the last decade.
3. Proper fit – The dimensions match the OEM spec exactly. It locks into the housing without forcing, and the foam seal prevents air leaks.
4. Good filtration – The paper media stops fine particles. After a full season in dusty conditions, the filter looked dirty but the engine ran clean.
5. Two-pack is practical – You can swap one now and store the other. No need to remember to reorder next spring.
6. No assembly required – Pull the old filter, drop this one in, close the cover. Takes two minutes.

Cons

1. Not washable or reusable – Unlike some foam or oiled cotton filters, this is a disposable paper filter. You throw it away after one season, which adds to landfill waste.
2. No foam pre-filter – Some OEM filters include a thin foam layer for heavy dust. This is just paper, so in extremely dusty environments (e.g., dry, sandy lawns), it may clog faster.
3. Packaging is minimal – The filters come in a simple plastic bag with no cardboard insert. They arrived fine for me, but I’ve seen reviews where one was slightly bent in transit. Check before installing.
4. Not for all Briggs engines – Even though the list is long, it doesn’t cover older Intek or Vanguard models. You must verify your engine’s model number—don’t assume compatibility.

Bottom Line

The 2Pack Air Filter 593260 798452 334404 is the kind of smart, low-effort purchase that keeps your mower running smoothly without breaking the bank. For $5.99, you get two filters that fit a huge range of common Briggs & Stratton engines, seal tightly, and trap dust effectively. It’s not a premium foam filter for extreme conditions, but for the average homeowner swapping filters once a year, it’s a perfect value. I recommend buying this pack if you own a mower with a 500EX, 550EX, or 625EX—keep one in the garage and you’ll never run a season with a clogged filter again.

Frequently Asked Questions

Q: How do I know if this filter fits my engine?
Check the model number on your engine’s sticker (usually near the spark plug or under the air cleaner cover). If it matches any of the numbers listed—4247, 5432, 5432k, 09P00, 09P702, 500EX, 550EX, 575EX, 625EX, 675EXI, 725EXI—you’re good. Also cross-reference with OEM part numbers 593260, 798452, or 334404.

Q: How often should I replace this filter?
For a typical homeowner mowing a 1/4-acre lawn once a week, replace it once per season (every 25–50 hours of use). If you mow in dusty or dry conditions, check it halfway through the season and swap if it looks dark or clogged.

Q: Can I clean this filter and reuse it?
No. This is a dry paper filter designed for one-time use. You can tap it gently to remove loose debris, but washing or blowing it out with compressed air will damage the paper pleats and let dirt through. Just replace it—that’s why you get two.
