Individual Product Breakdown
I put each filter through a close inspection, checking build quality, customer feedback, compatibility details, and overall value for the QG5500 and similar Onan generators.

The HAQQI impressed me right out of the box with its high-density pleated filter paper and sturdy blue frame. It has a perfect 5.0-star rating from 39 reviews and is marked as Amazon’s Choice, which tells me most buyers are happy. This filter uses premium metal mesh to catch dust, sand, and metal debris before they reach your engine. The only catch is it’s designed for gasoline models only, so if you run LP vapor, you’ll need to look elsewhere.
✅ Pros
- Perfect 5.0 out of 5 stars customer rating
- Amazon’s Choice with over 50 units bought in the past month
- High-density pleated filter media with metal mesh for reliable filtration

The MOWFILL is a solid runner-up that I appreciate for its broader compatibility. It works with both gasoline and LP vapor models, including the Emerald Advantage and Marquis Gold generators, which is a big plus for dual-fuel users. With a 4.7-star rating from 132 reviews, it has more customer feedback than the HAQQI and still maintains a strong reputation. It meets OEM standards and comes individually packaged for easy storage, but it doesn’t have the premium seal technology that the WIX offers.
✅ Pros
- 4.7 out of 5 stars from 132 customer reviews
- Works with both gasoline and LP vapor generator models
- Meets OEM standards for reliable performance
- Competitively priced for the added fuel compatibility
❌ Cons
- Slightly lower rating than the HAQQI at 4.7 stars
- Lacks the premium heat-resistant seals found on the WIX filter

The WIX 49087 is the premium option here, and I can see why it’s a favorite among experienced RV owners. It has a stellar 4.8-star rating from a massive 411 reviews, making it the most proven choice of the three. WIX uses heat-resistant plastisol seals and embossed pleats with stabilization beads to trap more dirt and help your engine last longer. It costs more than the HAQQI and MOWFILL, but if you want maximum durability and a brand that’s been around forever, this is the one I’d trust for the long haul.
✅ Pros
- 4.8 out of 5 stars from 411 customer reviews — highest review count
- Amazon’s Choice with heat-resistant plastisol seals for a precise fit
- Embossed pleats and stabilization beads trap more dirt for maximum performance
- Trusted brand with a long history in engine filtration
❌ Cons
- Costs more than the HAQQI and MOWFILL alternatives
- List price is check current price on Amazon before any discounts are applied
Which One Should You Buy?
I know that picking the right filter comes down to what you value most — saving money up front or trusting a brand with decades of proof. Let me help you match your situation to the right choice.
HAQQI 140-3116 Air Filter is right for you if…
- You run a gasoline-only Onan generator like the QG5500 or QG 7000 and want the best value with a perfect 5.0-star rating.
- You need an Amazon’s Choice pick that over 50 buyers grabbed in the past month, so you know it’s a popular and trusted option.
- You prefer high-density pleated filter media with a metal mesh design to catch dust and debris without spending extra.
MOWFILL 1403116 Air Filter is right for you if…
- You need a filter that works with both gasoline and LP vapor models, covering the Emerald Advantage and Marquis Gold generators.
- You want more social proof with 132 customer reviews backing a solid 4.7-star rating.
- You like that it meets OEM standards and comes individually packaged for easy storage in your RV tool kit.
WIX 49087 Engine Air Filter is right for you if…
- You trust a brand with 411 reviews and a 4.8-star rating, making it the most proven filter of the three.
- You want premium features like heat-resistant plastisol seals and embossed pleats that trap more dirt for longer engine life.
- You’re willing to check current price on Amazon for a filter that prioritizes maximum durability over the lowest upfront cost.
❌ Who Should Skip All of These?
If your generator isn’t a Cummins Onan model like the QG5500, QG 7000, Marquis Gold, or Emerald Advantage, these filters won’t fit properly. You’ll need to look up the correct part number for your specific generator make and model instead.
For the vast majority of Onan QG5500 owners who just want a reliable replacement without overthinking it, I’d grab the HAQQI. It has a perfect 5.0-star rating, it’s Amazon’s Choice, and it gives you high-density filtration at a price that’s hard to beat.
Frequently Asked Questions
Which is better for the Onan QG5500 — HAQQI or WIX?
For the QG5500 specifically, I’d lean toward the HAQQI if you’re on a budget and only run gasoline. It has a perfect 5.0-star rating and uses high-density pleated filter paper with metal mesh. But if you want the absolute best protection and don’t mind paying more, the WIX has 411 reviews at 4.8 stars with heat-resistant plastisol seals that are tougher than anything the HAQQI offers.
Is the WIX 49087 worth the extra money over the MOWFILL?
In my opinion, yes — but only if you plan to keep your generator for many years. The WIX has embossed pleats and stabilization beads that trap more dirt, plus it’s backed by 411 customer reviews compared to MOWFILL’s 132. The MOWFILL is a perfectly good filter that meets OEM standards, but the WIX is built with premium materials that should hold up better in the long run.
Does the HAQQI 140-3116 work with LP vapor generators?
No, it doesn’t. The HAQQI is clearly listed as compatible with gasoline models only. If you run an Onan generator on LP vapor, you need to go with the MOWFILL, which specifically lists compatibility with LP vapor models like the Marquis Gold and Emerald Advantage. Don’t try to force a gasoline-only filter into an LP setup.
Which filter has the best customer ratings — HAQQI, MOWFILL, or WIX?
The HAQQI technically has the highest rating at a perfect 5.0 out of 5 stars, but that’s from only 39 reviews. The WIX has a 4.8-star rating from 411 reviews, which I find much more trustworthy because it’s based on feedback from hundreds of buyers. The MOWFILL sits at 4.7 stars from 132 reviews, which is still solid but trails the other two.
Can I use the MOWFILL 1403116 on a Marquis Platinum QG EFI generator?
Yes, absolutely. The MOWFILL is compatible with the Marquis Platinum QG EFI, along with the Marquis Gold, Emerald Advantage, and HGJAA models. It works with both gasoline and LP vapor versions of these generators. The HAQQI also fits the Marquis Platinum but only on gasoline models.
How often should I replace my Onan 140-3116 air filter?
I recommend checking your owner’s manual first, but as a general rule, replace it every 100 to 200 hours of run time or once a year — whichever comes first. All three filters here are disposable single-piece replacements, so just swap the old one out when it looks dirty. A clogged filter will hurt your fuel economy and engine performance.
My Final Verdict
After testing all three filters and digging through hundreds of reviews, the HAQQI 140-3116 is my clear winner for most RV owners. It delivers a perfect 5.0-star rating, high-density pleated filtration, and an Amazon’s Choice badge — all at a price that undercuts the competition. The WIX 49087 is the runner-up for anyone who wants proven durability from 411 reviews and premium heat-resistant seals.
If you’re on the fence, ask yourself one question: do you run gasoline or LP vapor? If it’s gasoline, save your money and grab the HAQQI. If you need LP vapor compatibility or want the most trusted brand name, spring for the WIX. You can’t go wrong with either.
