A backpack filter can be considered one of the crucial accessories that one requires for keeping an aquarium clean and healthy. The hinged filter for the aquarium is easily inserted into the back of a fish tank filter that has the capability of filtering impurities, excess nutrients, and debris from the water efficiently. Its compact design will make it very appropriate for aquarists with limited space within the tank, yet they require a water filter system for backpacking, such as the best water filter purifier for backpacking and more.

Now, the question that arises here is how exactly a backpack filter benefits your aquarium and how the working of such a filter takes place. Let’s dive into the details.

What Is a Backpack Filter
A backpack filter is also referred to as a hang-on-back (HOB) filter, and this is a filtration system that is placed on the outer part of the aquarium. It works with a pump that sucks the water contained in the tank and passes through various media layers and returns the water. It is the “backpack” design that is specifically incorporated to detach the filtration unit from the main tank to enhance water circulation while occupying the fish’s space.
They are commonly used with freshwater tanks and are advantageous when used in planted tanks that contain plants. Their effective water filtration system is useful in determining water purity and thus enabling the growth of these plants.
Structures and Features
- Convenient design: The suction style is mounted at the back of the tank and hence does not occupy space inside the aquarium.
- Multi-Stage Filtration: Includes mechanical, biological, and optional chemical filtration for comprehensive water purification.
- Water Delivery Control: Flexibly regulate water through patterns of flow that are better aligned for the size of the tank, along with fish types.
- Surface Skimming: Some models, such as the hygger HG150, are equipped with an oil film remover that will remove all residues on the surface.
Water Filter Systems Backpacking: Working Principle
Therefore, the working principle of a backpack filter is that the water passes through several stages that improve the quality of the water it deals with.
- Water Circulation: The filter draws the water from the aquarium with the help of a telescopic intake tube or with the help of a surface skimmer.
- Mechanical Filtration: A filter pad or floss is the first stage in the filtration system so it collects any large matter which comprises fish waste, food remains or plants.
- Biological Filtration: Filter balls and rocks containing beneficial bacteria to convert toxic ammonia and nitrites into nitrates for the fish.
- Chemical Filtration (Option): Toxins, odors, and discoloration can be removed through the use of activated carbon or resin.
- Water Return & Aeration: The purified water is returned to the aquarium through any of the outlets which include; a spray bar, a directional spout or an air-infusion tube for purposes of aquarium aeration.

The Best Water Filter Purifier Backpacking in Fish Tanks
Some of the key characteristics of a good backpack filter include filter efficiency, ease of cleaning, and low noise levels. In this case, the following considerations may come in handy when choosing the best model:
- Filtration Efficiency: Since they undergo mechanical, biological, as well as optional chemical purification, they promise maximum filtration.
- Diameter Index: The size of the aquarium can be easily adjusted to fit the group of fish and the type of plants.
- Motor: A motor that does not produce any sound at all is preferred for home and office use.
- Maintenance: Some filters use media that is easy to replace, and waste disposal systems make it easy to maintain the filter.
- Durability: Using good quality material enhances the durability of products so that they will be a good performer in due course.
The hygger HG150 Backpack Aquarium Filter is arguably the best, as it comes with practically all the features that are essential in maintaining a healthy aquatic ecosystem for the fish, with quiet operation and easy maintenance.

Step-by-Step Installation Guide
- Unbox and Inspect Components
- Ensure all parts are included: filter unit, inlet pipe, skimmer, filter media, and mounting clips.
- Check for any damage before assembling.
- Attach the Intake Pipe
- The telescopic intake pipe can be adjusted to different lengths to suit your tank depth.
- Securely connect the pipe to the filter’s intake port.
- Mounting the Filter on Your Tank
- Designed for rimless tanks (up to 12mm thickness); secure the filter using the included clips.
- Ensure the unit sits firmly to avoid vibrations or leaks.
- Priming the Filter
- Fill the filter chamber with water before plugging it in to prevent dry-run damage.
- This step is crucial for ensuring proper startup and preventing motor burnout.
- Powering On the Filter
- Plug in the filter and turn it on.
- Adjust the flow rate using the control knob to create the desired water movement.

Optimizing the Filter for Maximum Performance
- Adjust Flow Rate & Oxygenation
- Use the flow control dial to regulate water movement.
- Attach the air infusion tube for additional oxygenation if needed.
- Choose Your Water Return Method
- Spray Bar: Gentle aeration, ideal for planted tanks.
- Directional Spout: Focused water flow for improved circulation.
- Air Infusion Tube: Enhances aeration by injecting oxygen bubbles.
- Maintaining a Clean & Efficient System
- Clean the surface skimmer weekly to remove excess oils.
- Replace the filter floss every 2–4 weeks for optimal mechanical filtration.
- Rinse the biological media (ceramic balls) in tank water during routine maintenance to preserve beneficial bacteria.
Troubleshooting Common Issues
Issue: Weak Water Flow or No Filtration
1. Check for clogs in the intake pipe or filter media.
2. Ensure the impeller is clean and moving freely.
Issue: Loud Noise or Vibrations
1. Confirm the filter is securely mounted.
2. Make sure the water level is adequate to prevent air bubbles from causing noise.
Issue: Surface Skimmer Not Functioning Properly
1. Adjust the skimmer’s height to ensure it is level with the water surface.
2. Remove debris buildup from the skimmer intake.
Key Takeaways
- Backpack filters are effective, compact, and cannot be done without for keeping the water clear in the tank.
- For instance, they employ mechanical, biological, and chemical filtration only where necessary to eliminate the solids, toxins, and nutrient overlays.
- The hyggerHG150 is among the most suitable backpack filters with flexibility on the flow range and easy maintenance as well as quiet operation.
- However, regular cleaning and installing filters well should be done well to ensure good performance and durability of the filters.
Backpack filters can enhance the quality of water in your tank, thus creating a favorable environment for the organisms to live in. This way, you will also get to enjoy a clear, healthy home aquatic environment by just selecting a good filter and following recommended maintenance procedures.
