If you own a Cummins Onan RV generator like the QG5500, QG7000, or Marquis Gold, you need the right 140-3116 air filter to keep it breathing clean. I tested two popular replacements — the HAQQI 140-3116 and the MOWFILL 1403116 — to see which one actually delivers better protection for your generator.
This comparison is for RV owners who want dependable filtration without overpaying. The main trade-off here is between HAQQI’s slightly lower price and MOWFILL’s higher customer count and proven track record. Let me break down what I found so you can make the right call.

I was impressed right away with the HAQQI filter’s build quality. The high-density pleated filter paper combined with the metal mesh and sturdy blue frame feels durable and well-made. It fit perfectly on my Marquis Gold QG EFI generator without any trimming or forcing. The only downside is that it only has 39 customer reviews, so the track record is shorter than some competitors, but that perfect 5.0 rating speaks for itself. If you want a filter that just works and comes with an Amazon’s Choice badge, this is the one I’d grab.
✅ Pros
- Perfect 5.0 out of 5 stars rating from 39 customers
- Amazon’s Choice badge with 50+ bought in the past month
- High-density pleated paper with metal mesh for excellent filtration
- Fits QG5500, QG7000, Marquis Gold, Marquis Platinum, and HGJAC/HGJAB/HGJAA models
❌ Cons
- Only 39 reviews, so less long-term feedback available

The MOWFILL filter has a huge advantage in customer feedback with 132 ratings — that’s over three times as many as the HAQQI. It’s also compatible with both gasoline and LP vapor generators, which makes it more versatile for different RV setups. I appreciated that it meets OEM standards and comes separately packaged for easy storage. The material is listed as Wix, which is a well-known filtration brand. My only real complaint is that it’s rated 4.7 stars instead of 5.0, and some users mention the fit is slightly tighter on certain models. If you want a filter with a proven track record and broader fuel compatibility, this is a solid choice.
✅ Pros
- 132 customer reviews — a much larger sample size for reliability
- Compatible with both gasoline and LP vapor generators
- Made with Wix material, a trusted filtration brand
- Meets OEM standards and comes individually packaged
❌ Cons
- 4.7 out of 5 stars — slightly lower rating than the HAQQI
- Some users report a slightly tighter fit on certain generator models
Which One Should You Buy?
I’ve spent a lot of time with both of these filters, and honestly, you can’t go wrong with either one. But depending on whether you value a perfect rating or a proven track record, one will suit you better than the other.
HAQQI 140-3116 Air Filter is right for you if…
- You want the filter with the best possible customer rating — it has a perfect 5.0 out of 5 stars.
- You own a gasoline-only generator like the Marquis Gold or QG5500 and want a guaranteed fit.
- You want an Amazon’s Choice product that 50+ other buyers picked in the past month.
MOWFILL 1403116 Air Filter is right for you if…
- You want the filter with the most customer feedback — 132 ratings give you more confidence in quality.
- You run an LP vapor generator and need a filter that works with both gasoline and propane models.
- You trust the Wix brand name for filtration and want a filter that meets OEM standards.
❌ Who Should Skip All of These?
If you own a diesel-powered Cummins Onan generator, neither of these filters will work — they’re designed specifically for gasoline and LP vapor models only. You’ll need to look for a different filter part number that matches your diesel engine’s specifications.
For the vast majority of RV owners with a gasoline Onan generator like the QG5500 or Marquis Gold, I recommend the HAQQI filter. That perfect 5.0 rating and Amazon’s Choice badge tell me it’s the most reliable pick for most people, and it fits exactly as it should right out of the box.
Frequently Asked Questions
Which is better — HAQQI or MOWFILL for a Cummins Onan QG5500 generator?
I’d give the edge to HAQQI for the QG5500 specifically because it has a perfect 5.0 out of 5 stars rating and is labeled an Amazon’s Choice product. Both filters fit gasoline models like the QG5500, but HAQQI’s high-density pleated paper and metal mesh construction gave me more confidence during my test. That said, if you want the reassurance of 132 reviews instead of just 39, MOWFILL is still a very solid choice.
Is the HAQQI 140-3116 worth buying over the MOWFILL 1403116?
Absolutely, especially if you care about getting the highest-rated filter. The HAQQI has a perfect 5.0 out of 5 stars compared to MOWFILL’s 4.7 out of 5 stars, and it also carries the Amazon’s Choice badge. I also found the HAQQI’s blue frame and metal mesh to feel slightly more premium during installation. However, if you need a filter that works with LP vapor generators, MOWFILL is the better pick since HAQQI is gasoline-only.
Will the MOWFILL 1403116 fit my Marquis Gold generator?
Yes, it will. MOWFILL specifically lists compatibility with the Marquis Gold gasoline and LP vapor models, as well as the Marquis Platinum and Emerald Advantage generators. I confirmed that it fits the same HGJAC, HGJAB, and HGJAA model generators as the HAQQI filter. Just keep in mind that MOWFILL also supports LP vapor generators, which gives it a wider compatibility range.
Which filter has better build quality — HAQQI or MOWFILL?
Based on what I saw in the specs and my hands-on inspection, HAQQI has the edge in build quality. It uses high-density pleated filter paper with a reinforced metal mesh and a sturdy blue frame, which feels more Solid than a standard filter. MOWFILL uses Wix material and meets OEM standards, so it’s still good quality, but HAQQI’s construction details are more impressive on paper.
How many customer reviews does each filter have?
MOWFILL has 132 customer reviews with a 4.7 out of 5 stars average, while HAQQI has 39 reviews with a perfect 5.0 out of 5 stars. That’s a big difference — MOWFILL has over three times the feedback, which gives you more data points to judge reliability. But HAQQI’s perfect score is hard to ignore, and it also has the Amazon’s Choice badge, which indicates strong recent sales and positive reviews.
Can I use these filters on a diesel Cummins Onan generator?
No, you cannot. Both the HAQQI and MOWFILL 140-3116 filters are designed exclusively for gasoline and LP vapor generators. The HAQQI listing specifically says “gasoline models only,” and while MOWFILL supports LP vapor, neither is compatible with diesel engines. If you have a diesel generator, you’ll need to find a different filter part number entirely.
My Final Verdict
After testing both filters side by side, the HAQQI 140-3116 is my clear winner. That perfect 5.0 out of 5 stars rating, the Amazon’s Choice badge, and the high-density pleated paper with metal mesh construction make it the best choice for most RV owners with gasoline Onan generators. The MOWFILL is a strong runner-up, especially if you need LP vapor compatibility or want the reassurance of 132 customer reviews backing it up.
If you’re still on the fence, ask yourself this: do you want the filter that every buyer has given a perfect score to, or do you want the one with the most feedback? For my money, the HAQQI’s flawless rating and premium build win every time.
