Glacier Fresh AQUAGO Review

Why RV Water Filtration Matters

If you’ve spent any real time RVing, you already know this: campground water quality is wildly inconsistent. One stop has clean, great-tasting city water, while the next has heavily chlorinated, sediment-filled well water you wouldn’t want to drink unfiltered.

After more than three years of RV travel and testing multiple water filtration setups, we’ve learned that a reliable RV water filter system isn’t a “nice to have”; it’s essential. Clean water affects everything from drinking and cooking to showering and protecting your RV’s plumbing.

That’s what led us to the Glacier Fresh AUQAGO 3-Stage RV Water Filter System. We’ve used inline filters, bulkier multi-stage systems, and higher-priced options, and this system has become our go-to because it balances filtration performance, flow rate, size, and cost better than anything else we’ve tried.

If you’re researching options and comparing systems, this Glacier Fresh AQUAGO review is based on real-world RV use, not just specs on a product page. (We also break down how it compares to other top systems in our full best RV water filter comparison.)

Glacier Fresh AQUAGO: Quick Overview

The Glacier Fresh AUQAGO is a 3-stage external RV water filtration system designed for RVs, fifth wheels, travel trailers, camper vans, and even boats. Instead of relying on a basic inline filter, this system provides multi-layer filtration in a compact, easy-to-manage setup.

What immediately sets it apart is its size-to-performance ratio. The AUQAGO uses compact 5-inch filters, making it one of the most space-efficient multi-stage RV water filters available, without sacrificing filtration quality or flow rate.

The system typically sells for $299, with replacement filters priced at $59, making it noticeably more affordable than many comparable multi-stage systems. It’s built with a lightweight polycarbonate carbon fiber frame, weighs about 10 pounds, and includes thoughtful extras like stainless steel quick-connect fittings and a built-in pressure regulator.

In short, the Glacier Fresh AUQAGO is designed for RVers who want better water quality than an inline filter, without the bulk, complexity, or high replacement costs that often come with larger filtration systems.

This combination of small filter size, fine-micron filtration, and high flow rate enables the Glacier Fresh AQUAGO to outperform many bulkier RV water filter systems without taking up valuable storage space.

Filtration Performance & Water Quality

This is where the Glacier Fresh AUQAGO really separates itself from basic inline RV water filters.

The system’s 0.2-micron high-flow filter does an excellent job of reducing sediment, fine particulates, and common contaminants found in both city water and well water. We’ve used this system at older campgrounds with questionable hookups and newer parks with heavily treated municipal water, and the difference is immediately noticeable.

The most significant improvement we noticed was water clarity and taste. Chlorine-heavy water is noticeably smoother, and sediment that would normally cloud water or clog inline filters is handled easily by the multi-stage setup. 

Even in areas where campground water tends to carry fine particles, the AUQAGO maintained strong flow without frequent pressure drops.

That smaller micron rating matters. Many RV inline filters don’t filter nearly as fine, which means smaller particles can still pass through. With the Glacier Fresh AQUAGO, the filtration feels consistent from campground to campground, which adds a lot of peace of mind when you’re constantly moving.

If you travel full-time or bounce between different regions, this level of filtration is precisely why a multi-stage system like this often outperforms cheaper alternatives.

Installation & Ease of Use

One of the biggest advantages of the Glacier Fresh AQUAGO is how easy it is to set up and break down, especially compared to bulkier multi-stage systems.

The system uses stainless steel garden hose quick-connect fittings, which allow you to connect directly to city water or well water at the campground in seconds. Setup is a simple three-step process: connect the inlet hose, connect the outlet hose, and turn on the water.

Glacier Fresh also includes a built-in pressure relief regulator, which helps protect your RV’s plumbing and eliminates the need for an additional external regulator in most situations. The included portable rope makes it easy to hang or position the unit near the water hookup without having to permanently mount it.

For RVers who move frequently, this matters. The AUQAGO is quick to disconnect, easy to drain, and light enough to store without hassle. It doesn’t feel like a chore every time you arrive at or leave a campground, which is something we’ve definitely experienced with more complex systems.

Size, Flow Rate & Practical Design

The Glacier Fresh AQUAGO excels at balancing size and performance. Many multi-stage RV water filter systems are bulky, heavy, and awkward to store. This one isn’t.

Thanks to its compact 5-inch filters and low-profile frame, the AUQAGO takes up significantly less space than most multi-stage systems while still delivering strong filtration. It fits easily in a pass-through or basement storage compartment and doesn’t require a dedicated mounting location.

Flow rate is another area where this system performs better than expected. Even with 0.2-micron filtration, we haven’t noticed a meaningful drop in water pressure during everyday use, including showers, dishes, and laundry. 

That’s not always the case with finer filtration systems, especially cheaper or older designs.

For full-time RVers or anyone moving often, this combination of small footprint, lighter weight, and consistent flow makes a noticeable difference. It feels like a system designed specifically for real RV travel, not just occasional weekend use.

Glacier Fresh AQUAGO vs Other RV Water Filters

When comparing the Glacier Fresh AQUAGO to other RV water filter options, the differences become pretty clear.

Inline RV water filters are affordable and easy to use, but they’re limited. They don’t filter as finely, clog faster in high-sediment areas, and often struggle with taste and consistency when moving between campgrounds.

On the other hand, many large multi-stage RV filtration systems offer good performance but come with trade-offs: bulky frames, heavier weight, lower flow rates, and significantly higher replacement filter costs.

The AUQAGO sits in a sweet spot between those two extremes. It delivers true multi-stage, 0.2-micron filtration like higher-end systems, but in a much smaller, lighter, and more affordable package. 

Replacement filters are also reasonably priced, which matters over the long term if you RV frequently or full-time.

Compared to other systems we’ve tested and reviewed in our best RV water filter guide, the Glacier Fresh AQUAGO consistently offers the best balance of filtration performance, flow rate, size, and overall value.

Long-Term Ownership & Maintenance

Long-term maintenance is where some RV water filter systems become frustrating, either due to frequent filter changes or expensive replacements. That hasn’t been the case with the Glacier Fresh AQUAGO.

The replacement filters are reasonably priced compared to many multi-stage systems, which helps keep ongoing costs manageable. 

Filter life will always depend on how often you travel and the quality of campground water you’re connected to, but overall, the system has been consistent and reliable without needing constant attention.

Changing filters is straightforward and doesn’t require special tools. The compact design also makes it easier to handle during maintenance compared to larger, heavier systems. For full-time RVers or frequent travelers, that simplicity matters.

So far, the AUQAGO has held up well with regular use, and the two-year warranty provides additional confidence for long-term ownership.
