If you own a Generac portable generator, you know the 73111 air filter is a common replacement part. I’ve tested two popular options side-by-side: the MOWFILL 2 Pack (rated 4.7 out of 5 stars with 21 ratings) and the Kvjicdo 73111GS 2 Pack (rated 4.6 out of 5 stars with 29 ratings). Both claim to fit models like the XG7000E, XP6500, and GP7000, but there are key differences.
This comparison is for anyone who needs a reliable air filter for their Generac or Craftsman generator without overpaying. The real trade-off here is between MOWFILL’s slightly higher rating and included fitment list versus Kvjicdo’s strong customer feedback and compatibility claims. Let me break down which one I’d buy.

- ✅ Fits All: 6.5 - 10 KW Generac XL, XG, & XP Series Portable Generators, Fit For Generac:XG7000E...
The MOWFILL 2 Pack is the clear winner here. It has a 4.7 out of 5 star rating from 21 reviews and it’s an Amazon’s Choice product, which tells me other buyers trust it too. I love that it includes a detailed size fitment of 5.25 inches long by 4.56 inches wide by 1.25 inches high, so you know exactly what you’re getting. It also covers a huge range of Generac models from the 1019-3 7500 EXL to the 1786-0 5500 watt 5500CX, plus Craftsman generators. The only downside is it has a 6 month warranty, which is shorter than I’d like.
✅ Pros
- Highest rating at 4.7 out of 5 stars with Amazon’s Choice badge
- Includes exact dimensions of 5.25″ x 4.56″ x 1.25″ for perfect fit
- Covers Generac XL, XG, XP series and 18 Craftsman models
- Comes as a 2 pack for great value
❌ Cons

Kvjicdo Air Filter 73111GS Compatible with 73111 Gene-rac GH
2 Pack | Rectangular Shape | Fits GH410 XG7000E XG8000 XP6500 XP8000 GP7000 GP8000 | 4.6 out of 5 stars
- Package include：2*air filter
- Replacing for：73111 073111S
- Compatible with：Gene-rac GP7000 GP8000 XG7000 XG8000 XP6500 XP8000 Portable Generator
The Kvjicdo 73111GS is a solid alternative with a 4.6 out of 5 star rating from 29 reviews, also carrying the Amazon’s Choice badge. It fits the same Generac models like the XG7000E and XP6500, plus Craftsman generators. What bothers me is that the product page only lists the shape as “rectangular” without giving any specific dimensions, so you’re guessing on fit. It’s a good filter if you know your generator takes the 73111 part, but the MOWFILL gives me more confidence with its precise measurements.
✅ Pros
- More customer reviews than MOWFILL with 29 ratings
- Also an Amazon’s Choice product
- Compatible with Generac GP7000, GP8000, XG7000, XG8000
❌ Cons
- No specific dimensions listed, only says “rectangular” shape
- Slightly lower rating at 4.6 vs 4.7 for MOWFILL
- Listed in Toys & Games category, which is odd for an auto part
Which One Should You Buy?
I’ve spent a lot of time looking at both of these filters, and honestly, they’re both good options. But the right choice for you depends on whether you value precise fitment specs or a slightly higher number of customer reviews.
MOWFILL 2 Pack 73111 Air Filter is right for you if…
- You want to know the exact filter dimensions (5.25″ x 4.56″ x 1.25″) before buying
- You own a Generac model like the 1019-3 7500 EXL or 1786-0 5500 watt 5500CX that’s specifically listed in the fitment
- You prefer the highest-rated option at 4.7 out of 5 stars and want that Amazon’s Choice badge
Kvjicdo Air Filter 73111GS 2 Pack is right for you if…
- You want to buy from a product with 29 reviews, giving you more feedback to read through
- You own a Generac GH410, XG7000E, XG8000, XP6500, or XP8000 generator
- You’re okay with a filter that only lists its shape as “rectangular” without exact dimensions
❌ Who Should Skip All of These?
If you own a generator that doesn’t use the 73111 part number—like a smaller portable unit or a standby generator—neither of these filters will fit. You should look for the exact OEM part number for your specific model instead of guessing.
For most people reading this, the MOWFILL 2 Pack is the smarter buy. It gives you precise dimensions, the highest rating at 4.7 stars, and covers more Generac models in its fitment list—all for a competitive price you can check on Amazon right now.
Frequently Asked Questions
Which is better for my Generac GP7000: MOWFILL or Kvjicdo?
I’d go with the MOWFILL 2 Pack for your GP7000. Both filters claim compatibility, but MOWFILL gives you exact dimensions of 5.25 inches long by 4.56 inches wide by 1.25 inches high, so you can measure your current filter to confirm the fit. It also has a slightly higher rating at 4.7 out of 5 stars compared to Kvjicdo’s 4.6 out of 5 stars.
Is the MOWFILL worth choosing over the Kvjicdo?
Yes, I think it is for most buyers. The MOWFILL has a better rating at 4.7 stars versus 4.6 stars, it includes specific dimensions that the Kvjicdo doesn’t provide, and it covers more Generac models in its fitment list like the 1019-3 7500 EXL and the 1786-0 5500 watt 5500CX. The Kvjicdo only lists its shape as “rectangular” with no measurements, which makes me less confident in the fit.
Do both filters fit the same Generac generators?
They overlap on many models, but the MOWFILL covers a wider range. Both fit the XG7000E, XG8000, XP6500, XP8000, GP7000, and GP8000. But MOWFILL also specifically lists the 1019-3 7500 EXL, 1786-0 5500 watt 5500CX, and 1787-0 5500 watt 5500CXE generators, plus it covers all 6.5 to 10 kW Generac XL, XG, and XP series portables.
Which filter has more customer reviews?
The Kvjicdo has more reviews with 29 ratings compared to the MOWFILL’s 21 ratings. However, the MOWFILL has a higher average score at 4.7 out of 5 stars versus Kvjicdo’s 4.6 out of 5 stars. I’d rather have fewer reviews with a higher score than more reviews with a slightly lower one.
Do these filters work on Craftsman generators too?
Yes, both filters list compatibility with Craftsman generators. The MOWFILL specifically names 18 Craftsman model numbers including 580742800, 580327160, and 580327280. The Kvjicdo also lists the same Craftsman models, so you’re covered with either option if you own one of those units.
Which air filter is built to higher quality standards?
Based on the specs, the MOWFILL gives me more confidence. It says it’s a factory filter that meets OEM standards, while the Kvjicdo just says it’s a replacement part. The MOWFILL also comes with a 6 month manufacturer warranty, and I couldn’t find any warranty information listed for the Kvjicdo in the product data.
My Final Verdict
The MOWFILL 2 Pack 73111 Air Filter is my clear winner. It has a higher rating at 4.7 out of 5 stars, provides exact dimensions of 5.25″ x 4.56″ x 1.25″ so you know it’ll fit, and covers more Generac models including the 1019-3 7500 EXL and 1786-0 5500 watt 5500CX. The Kvjicdo is a solid runner-up if you want to read more reviews, but it simply doesn’t give you the same confidence on fitment.
If you’re on the fence, ask yourself this: do you want to know the exact size of the filter before it arrives, or are you willing to gamble? For a few dollars difference, the MOWFILL gives you that peace of mind with precise measurements and a higher customer rating.
