When it comes to keeping a garden pond clean, clear, and healthy, the Oase Filtoclear Pressure Filter stands out as one of the most versatile and user-friendly systems available. Trusted by pond owners around the world, it combines mechanical, biological, and ultraviolet filtration in one compact, pressurized unit. Whether you have a small decorative pond or a medium-sized koi setup, the Filtoclear offers the performance and convenience you need to maintain pristine water with minimal effort.
What Is the Oase Filtoclear Pressure Filter?
The Oase Filtoclear is a sealed, pressurized pond filter designed to provide effective filtration while allowing water to be pumped to higher water features such as waterfalls and raised outlets. Unlike gravity-fed filters that must sit at water level, this pressure filter can be placed virtually anywhere—even below ground—making it extremely flexible for pond design and landscaping.
Its multi-stage filtration system includes:
- Mechanical filtration to remove debris
- Biological filtration to convert harmful wastes
- Built-in UV clarifier to eliminate green-water algae
This combination ensures that pond water not only looks clean but is also biologically safe for fish and plants.
How the Filtoclear System Works
The Filtoclear uses a smart three-step filtration process:
- Mechanical Filtration
Water enters the filter and passes through a series of foams that trap dirt, fish waste, and other particles. - Biological Filtration
Beneficial bacteria living within the filter break down ammonia and nitrite, helping to stabilize pond water. - UV Clarification
A powerful built-in UV lamp kills free-floating algae cells, keeping the pond crystal clear even in sunny conditions.
Because it operates under pressure, clean water can be routed upward—perfect for waterfalls, streams, and decorative fountains.
Why Pond Owners Love the Oase Filtoclear
Easy “Pull-to-Clean” Technology
One of the standout features is the exceptionally simple cleaning system. With Oase’s patented Easy Clean lever, you can compress the filter sponges from the outside—no need to open the unit or get your hands dirty. The waste is flushed out automatically when the cleaning function is activated.
Compact and Discreet
The sealed design allows the unit to be partially buried, hidden behind plants, or tucked away without affecting landscaping aesthetics. This makes it ideal for stylish garden ponds where appearance matters.
Reliable UV Performance
The built-in UVC clarifier is powerful enough to keep water clear even during algae-prone seasons. A clear water guarantee from Oase gives pond owners peace of mind.
Strong Build Quality
Like all Oase products, the Filtoclear is built to last—with durable materials, solid seals, and excellent long-term performance.
Best Uses for the Filtoclear Pressure Filter
- Small to medium ponds
- Ponds with waterfalls or raised water features
- Koi and goldfish ponds
- Ponds in sunny locations prone to algae bloom
Its pressurized function makes it especially valuable in setups where a gravity-fed filter wouldn’t work.

The Oase Filtoclear Pressure Filter is an outstanding all-in-one solution for pond owners who want clean, clear, and healthy water without complicated maintenance. Its advanced filtration stages, powerful UV clarifier, and effortless cleaning system make it one of the most convenient and effective filters on the market.
