Introduction to the Oase Filtoclear
The Oase Filtoclear Pressure Filter is one of the most reliable, compact, and user-friendly filtration systems designed for small to medium-sized ponds. Engineered in Germany and built with high-quality components, the Filtoclear is popular among pond owners who want consistently clear water without complicated maintenance. Its pressurised design allows it to be installed discreetly—hidden underground or beside the pond—while still delivering powerful mechanical and biological filtration. With built-in UV technology and its easy-cleaning mechanism, the Filtoclear is an excellent all-in-one solution for ornamental, wildlife, and lightly stocked koi ponds.
How the Filtoclear System Works
The Oase Filtoclear operates as a multi-stage filtration system that combines mechanical filtration, biological filtration, and UV clarification in one compact unit.
- Mechanical Filtration: Water first passes through the filter sponges, which capture suspended waste, algae particles, and debris.
- Biological Filtration: Beneficial bacteria living within the sponges break down ammonia and nitrite, creating stable and healthy water conditions.
- UVC Clarifier: The built-in ultraviolet unit destroys algae cells, preventing pea-green water and supporting crystal-clear clarity.
Because the filter is pressurised, clean water can be pumped to a waterfall or elevated stream, maintaining strong flow without losing pressure.
Ideal for Smaller Ponds and Water Features
The Oase Filtoclear is available in several sizes, typically ranging from 3000 to 30,000 litres, making it suitable for a wide variety of pond designs. It’s an excellent choice for:
- Ornamental garden ponds
- Wildlife ponds
- Small koi ponds
- Raised and formal ponds
- Ponds with waterfalls or water blades
Its compact size makes it easy to hide in landscaping, and because it is fully sealed, it can be installed below the water level—something many traditional pond filters cannot offer.
Easy Cleaning with the Oase “Easy Clean” System
One of the standout features of the Filtoclear Pressure Filter is its simple cleaning mechanism, which allows pond owners to wash the filter sponges without opening the unit. Using the external cleaning handle:
- Pump off the dirty water.
- Turn the handle to squeeze and compress the sponges.
- The waste is flushed out through the outlet.
This process takes only a few minutes and keeps your hands clean. The convenience of this system makes maintenance quick and stress-free, ensuring the filter works efficiently all year round.
Durable, Efficient, and Energy-Saving
Oase products are known for their durability, and the Filtoclear is no exception. The robust casing, high-quality sponges, and long-lasting UV units ensure years of dependable operation. The UV bulbs are energy-efficient yet strong enough to tackle algae problems even during peak summer months. Combined with a compatible Oase Aquamax or other filter pump, the Filtoclear offers powerful performance with low running costs.
