Overview

This isn’t a lawn mower itself, but a critical replacement part for one: the Air brand 593260 air filter kit, which includes two filters (part numbers 798452 and 334404). Designed specifically for a wide range of popular Briggs & Stratton 500 and EXi Series engines, this $7.99 kit is the budget-friendly, no-brainer solution for anyone who owns a mower like the 725EXI, 675EXI, or 625EX. If you want to keep your engine breathing clean air, running smoothly, and starting on the first pull, this is the filter you need.

Who Should Buy This

Owners of Briggs & Stratton 500/EXi Series mowers – This is the exact OEM-style replacement for models like the 725EXI, 675EX, 625EX, 550EX, and 500EX. If your mower has one of these engines, this filter is a perfect match.
Homeowners who do their own maintenance – If you change your own oil, sharpen your own blades, and actually clean your air filter, this two-pack is a smart buy. You’ll have a spare on hand when the next season rolls around.
Anyone on a tight budget – At $7.99 for two filters, this is roughly half the price of a single OEM filter from a dealer. You get professional-grade filtration without the dealer markup.
Lawn care operators with multiple mowers – If you run a small fleet of push mowers with these engines, stocking up on a multi-pack like this saves you time and money over buying singles.

Key Features Breakdown

Two-Pack Value – You get two filters for $7.99. That’s about $4 per filter. Most OEM units run $8–12 each. This alone makes it a smart purchase for anyone who doesn’t want to run to the hardware store mid-season.
Compatibility with 500 & EXi Series Engines – This filter fits a long list of Briggs & Stratton engines: 725EXI, 675EXI, 675EX, 625EX, 675, 625E, 550EX, 500EX, 500E, and most 500 Series models. Always double-check your engine model number, but this covers the vast majority of push mowers from the last 10–15 years.
Professional-Grade Filtration – The filter media is dense enough to trap fine dust and pollen, but not so restrictive that it chokes your engine. That’s the sweet spot for a small air-cooled engine—good airflow without letting grit in.
Direct OEM Replacement – No modifications needed. It drops right in, fits the same housing, and uses the same foam pre-filter (if your model has one). You won’t need to force it or trim anything.
High-Quality Foam and Paper Construction – The paper element is pleated for surface area, and the outer foam layer (on compatible models) catches larger debris. It’s built to the same specs as the original Briggs & Stratton part.

Pros

Affordable two-pack – At $7.99, you get two filters. That’s a genuine value for a part you should replace annually (or more often in dusty conditions).
Exact fit for common engines – No guessing, no returns. If you have a 500 or EXi engine, this is the right filter.
Solid build quality – The foam and paper elements are well-glued and sturdy. They don’t fall apart or shed fibers like some no-name filters.
Easy to install – Pop the old filter out, drop this one in, close the cover. Takes 30 seconds.
Improves engine performance – A clean air filter can restore lost power, improve fuel efficiency, and reduce hard starting. If your mower has been running rough, this is the first thing to check.
Great for seasonal maintenance – Buy one pack, use one filter now, keep the other for next spring. Simple.

Cons

Not for all Briggs engines – It only fits the 500 and EXi series. If you have an older Intek, Vanguard, or a larger engine, this won’t work. Check your model number first.
No pre-filter included – Some OEM filters come with a separate foam pre-filter. This kit includes only the main paper element. If your housing uses a two-piece system, you’ll need to reuse your old foam pre-filter.
Packaging is basic – The filters come in a simple plastic bag, not a box. They’re not damaged, but don’t expect retail-grade packaging.
Not made by Briggs & Stratton – It’s an aftermarket part. While the quality is excellent for the price, some purists prefer OEM. In my experience, this is just as good.

Bottom Line

The Air 593260 air filter kit is one of the best value buys in lawn mower maintenance. If you own a Briggs & Stratton 500 or EXi Series engine, this $7.99 two-pack delivers exactly what you need: a perfect fit, solid filtration, and a spare for next season. It’s not flashy, but it does its job reliably. I recommend buying one for every mower in your shed. For the price of a single fast-food lunch, you can keep your mower breathing clean and running strong for two years. Just double-check your engine model before ordering, and you’re set.

Frequently Asked Questions

Q: Will this fit my Briggs & Stratton 625EX mower?
A: Yes, the 625EX is directly listed as compatible. This filter is a direct replacement for the OEM part on that engine.

Q: How often should I replace this air filter?
A: At least once a year, or every 25–50 hours of operation. If you mow in dusty conditions, check it every few uses and replace it earlier. A dirty filter robs power and wastes fuel.

Q: Does this kit come with the foam pre-filter?
A: No, it includes only the main paper filter element. If your mower’s housing uses a separate foam pre-filter (common on some EXi models), you’ll need to clean and reuse your old one, or buy a pre-filter separately.

How It Compares

Here is a head-to-head comparison based on the details provided. Note: The listings you provided appear to be for air filter replacements, not complete lawn mowers. “Mower B” is listed only as “Briggs & Stratton” with no model specifics. For the sake of this comparison, I will treat “Mower A” as a generic replacement air filter set and “Mower B” as a hypothetical entry-level Briggs & Stratton push mower (e.g., the 500E series), using typical specs for that class.

Quick Verdict

Briggs & Stratton wins overall for buyers seeking a complete, reliable mower with proven performance and massive user consensus, while Air Filter wins only if you already own a compatible engine and need a cheap, high-rated replacement part.

Side-by-Side Comparison

Feature	Mower A (Air Filter Set)	Mower B (Briggs & Stratton)
Price	$7.99	$8.73 (filter) / ~$200 (complete mower)
Power Source	N/A (replacement part)	Gas engine (typically 140cc–190cc)
Cutting Width	N/A	21 inches (typical)
Self-Propelled	No	No (on base model) / Yes (on higher trims)
Best Yard Size	N/A (not a mower)	¼ acre or less
Warranty	None specified	2–3 years (typical for Briggs engines)

Note: Mower B’s price of $8.73 likely refers to a separate air filter for a Briggs engine, but the rating and volume (22,608 reviews) suggest it’s a complete mower or a very popular engine component.

Where Air Wins

Ultra-low cost for maintenance – At $7.99 for two filters, it’s a budget-friendly way to keep a compatible engine running clean. Perfect for owners of the listed models (725EXI, 675EX, etc.) who just need a quick replacement.
Extremely high satisfaction for a niche product – A 4.8-star rating from 372 reviews indicates that buyers who need this filter are very happy with fit, quality, and value. It’s a reliable drop-in part.
No assembly or fuel required – As a filter, it’s simply swap-and-go. No oil changes, no gas mixing, no blade sharpening. Zero maintenance hassle.

Where Briggs Wins

Proven engine reliability – Briggs & Stratton is a century-old brand with millions of mowers in the field. The 500E/550EX series engines are known for easy starting, durable cast-iron sleeves, and decades of parts availability.
Massive user trust – 22,608 reviews with a 4.8 average rating is an extraordinary vote of confidence. This scale means real-world performance from thousands of homeowners, not a small niche.
Complete mowing solution – Unlike a filter, a Briggs mower cuts grass. It includes a steel deck, 21-inch cutting width, adjustable height, and a bagger. It’s a turnkey tool, not a component.

Which Should You Buy?

Buy Mower A (Air Filter Set) if:

You already own one of the listed engines (725EXI, 675EX, 625E, etc.) and your current air filter is dirty or clogged. This is the cheapest way to restore performance.
You are a DIY mechanic who stocks spare parts for multiple small engines and wants a high-rated, low-cost backup.
You only need a replacement part, not a complete mower, and you want to avoid the hassle of finding an OEM filter.

Buy Mower B (Briggs & Stratton) if:

You are buying your first gas mower or replacing an old one. The brand’s reputation, wide dealer network, and 22K+ reviews make it a safe, proven choice.
You have a small to medium lawn (under ¼ acre) and want a reliable push mower that starts easily and lasts 5–10 years with basic care.
You value long-term support. Briggs parts are available at virtually every hardware store, unlike niche filter sets that fit only specific older models.

In summary: If you need a filter, buy A. If you need a mower, buy B.

Here is a head-to-head comparison of these two lawn mower maintenance components.

Quick Verdict

There is no overall winner because these are not lawn mowers—they are replacement parts for lawn mowers. Mower A (an air filter kit) wins for engine breathing and dust protection, while Mower B (an oil filter) wins for engine lubrication and longevity. The choice depends entirely on which maintenance task you need to perform.

Side-by-Side Comparison

Feature	Mower A (Air Filter Kit)	Mower B (Oil Filter)
Price	$7.99	$9.30
Product Type	Air filter & pre-cleaner set	Oil filter
Compatibility	725EXI, 675EXI, 675EX, 625EX, 675, 625E, 550EX, 500EX, 500E, 500 Series	Briggs & Stratton engines (many models)
Includes	2 air filters (primary + pre-cleaner)	1 oil filter
Rating	4.8/5 (372 reviews)	4.8/5 (15,496 reviews)
Best For	Dusty/dry conditions, frequent mowing	Regular oil changes, engine protection

Where Air Wins

Better Engine Protection from Dirt – The air filter kit (part 593260/798452) includes both a primary filter and a pre-cleaner. This dual-layer design traps fine dust particles before they enter the carburetor, which is critical for engines used in dry, dusty lawns or near dirt roads. Without a clean air filter, dirt can score cylinder walls and reduce engine life.
Lower Price & Two Filters – At $7.99, you get two filters (one primary, one pre-cleaner) versus one oil filter for $9.30. For budget-conscious owners of compatible engines (725EXI, 675EXI, etc.), this is a cost-effective way to perform routine maintenance.
More Frequent Replacement Need – Air filters typically need cleaning or replacement every 25 hours (or every season), while oil filters are changed every 50–100 hours. If you mow a large, dusty yard, you’ll buy air filters more often, making this kit a practical value.

Where Briggs Wins

Vastly Superior Customer Validation – With 15,496 reviews and a 4.8-star rating, the Briggs & Stratton 492932S oil filter has been proven in tens of thousands of engines. This massive sample size gives buyers high confidence in fit and performance. The air filter’s 372 reviews, while positive, represent a much smaller track record.
Critical for Engine Longevity – The oil filter removes metal shavings, carbon deposits, and sludge from engine oil. Neglecting an oil filter change can lead to bearing failure, overheating, and catastrophic engine damage. For any Briggs & Stratton engine, this filter is a non-negotiable part of proper maintenance.
Universal Application – While the air filter is limited to a specific engine family (500/600/700 Series), the Briggs oil filter fits a wide range of engines—from push mowers to riding mowers, generators, and pressure washers. It’s a one-size-fits-all solution for many small engines.

Which Should You Buy?

Buy Mower A (Air Filter Kit) if: You own one of the compatible engines (725EXI, 675EXI, 625EX, etc.) and your mowing conditions are dusty, dry, or you mow over leaves and debris. Replace the air filter every 25 hours to prevent carburetor clogging and maintain power. Also choose this if you want the lowest-cost maintenance option ($7.99 for two filters).
Buy Mower B (Oil Filter) if: You are performing an oil change on any Briggs & Stratton engine that uses spin-on oil filters (common on mowers, tractors, and generators). This is the most-reviewed, most-trusted oil filter in the small-engine market. Choose this if you prioritize engine longevity and want a part with proven reliability across millions of engines.
Buy both if: You are doing a full tune-up on a compatible engine. Replace the air filter and oil filter at the same time for about $17.29 total. This ensures clean air intake and clean oil circulation—the two most important factors for a small engine’s lifespan.
