OASE POND FILTERS | Choose The Right One For Your Clients Garden
31/03/2026
Adding a pond or water feature to a garden can instantly change the feel of the space, and there has been extensive research into the benefits water provides, not only to our mental well being but also to the surrounding environment and wildlife. Moving water, reflections, and wildlife can transform any outdoor space into a calmer and more relaxing environment.
Filtration and maintenance are two of the most important things to consider when planning a water feature. Knowing where to start can be daunting, but with over 20 years of experience, we've got your back. Your first question might be:
What Filter Do I Actually Need?
With so many technical terms and product choices out there, picking the right pond filter can feel overwhelming. The good news? It doesn’t have to be. Once you understand the basics, choosing the right Oase filter becomes much easier.
Why Pond Filters Matter
A pond filter isn’t just about clear water, it helps maintain a healthy ecosystem for plants, wildlife and fish.
An effective filter should not only physically remove dirt, leaves and fish waste, but also support beneficial bacteria which break this organic waste down. Beneficial bacteria also break down the compounds which algae requires to thrive, so supporting this bacterial process is incredibly important and often gets overlooked. Filtration also helps balance oxygen levels, keeping fish healthier and supporting pond health.
The Three Main Types Of Oase Filters
Oase filters are generally designed for three types of pond setups.
Smaller ponds: All-in-one filters provide a simple, compact solution that combines multiple features in a single unit. They are ideal for wildlife ponds or gardens where low maintenance is important.
Medium to large ponds: Flow-through filters offer stronger filtration and greater control. These systems handle larger water volumes and are better suited for ponds with fish.
Large ponds or koi setups: Professional modular systems deliver the highest level of filtration and water clarity, making them perfect for serious koi ponds or expansive garden water features.
All-In-One Filters: Simple and Easy
All-in-one filters are perfect for smaller ponds and offer a straightforward solution.
The Oase Filtral is a compact all-in-one system that combines a pump, filter, UV clarifier, fountain, and aeration into a single unit. With everything integrated, installation is quick and maintenance is simple
It’s especially well suited for wildlife ponds or lightly stocked garden ponds where ease of use is the priority.
The FiltoClear is a pressure filter, meaning it can push water uphill, making it ideal for ponds with a waterfall or raised stream.
It also features a built-in UV clarifier and an easy-clean system, so the filter can be cleaned without ever opening it. For ponds with a moderate number of fish, it offers a company tidy and powerful filtration solution.
Another great feature of the FiltoClear is that the main body of the filter can be buried. Ideal for keeping things neat and tidy around the pond!
Oase have recently released the FiltoClear 60000 & 90000. These are capable of filtering medium to larger ponds (depending on fish stock) which is great if you want a simple, easy to use system for larger bodies of water.
Flow-Through Filters: More Power For Larger Ponds
For medium to large ponds, flow-through filters provide stronger filtration and greater capacity.
The BioSmart range uses gravity-fed filtration, allowing water to flow naturally back into the pond. It combines mechanical and biological filtration with an integrated UV clarifier to help maintain clear water.
Inspection windows and a sludge outlet make it easy to see when cleaning is needed, keeping maintenance simple and straightforward.
The BioTec range offers even greater filtration power. Its Screematic technology removes larger debris early in the filtration process, reducing how often the filter needs cleaning.
This makes it an excellent choice for ponds with larger fish populations or installations that demand reliable, long-term performance.
Professional Systems For Koi Ponds
For large ponds and koi setups, the Oase ProfiClear range offers professional-level filtration.
These modular systems combine drum filtration with advanced biological filtration to deliver exceptional water clarity, even in heavily stocked ponds. They can also be expanded over time, making them a flexible solution as your pond grows.
Choosing The Right Filter
When selecting a filter, start by considering the size of the pond and how many fish it will contain, if any. It’s usually best to choose a slightly larger filter than you think you need, as this helps maintain better water quality over time.
It’s also important to think about how much maintenance your client is willing to carry out, as well as whether the filtration system needs to be hidden within the surrounding landscape.
Choosing the right pond filter doesn’t need to be complicated. Once you understand the key factors, selecting the right system becomes a straightforward process.
With the right filter in place, you can guarantee clearer water, healthier fish and far less maintenance, leaving more time for your clients to simply enjoy their pond.
