Aquarium Filter Cartridge Dymo Aqua Natura TN-44795, ABS housing with polyester sponge, 52×44×220 mm

Dymo Aqua Natura TN-44795 is an aquarium filter cartridge with an ABS outer housing and an internal polyester sponge element. With dimensions of 52×44×220 mm it is designed to fit compatible internal filter units and provides mechanical filtration by trapping debris, uneaten food and suspended particulates. The cartridge supports routine maintenance cycles in freshwater aquarium systems and helps maintain water clarity while allowing beneficial bacteria to colonize the sponge surface for biological filtration support.

Advantages

The rigid ABS housing ensures consistent shape and easy handling during replacement, while the polyester sponge element offers effective mechanical trapping of solid waste. Its compact dimensions make it suitable for confined filter chambers and enable straightforward installation and removal. The material combination resists deformation in normal aquarium conditions and provides a stable surface for microbial colonization, contributing to both mechanical and biological filtration functions.

Suitable for

• Internal aquarium filter units compatible with 52×44×220 mm cartridges
• Freshwater community tanks and species-specific setups requiring mechanical filtration
• Routine cartridge replacement during standard maintenance schedules
• Environments where a compact, rigid cartridge is preferred for easy handling

Key specifications

• Outer housing material: ABS plastic
• Filter element: polyester sponge
• Dimensions: 52 × 44 × 220 mm
• Filtration type: mechanical (particulate and debris removal)
• Intended water type: freshwater aquariums

How to use

Turn off the filter and disconnect electrical power before replacing the cartridge. Remove the filter cover or filter cassette to access the used cartridge, then pull out the old cartridge and dispose of it according to local waste regulations. Insert the Dymo Aqua Natura cartridge into the filter housing in the correct orientation until it seats securely, reassemble the filter components and restore power. Rinse the new cartridge briefly with aquarium water if required by the filter manufacturer to remove loose particles prior to initial use.

Usage recommendations

Replace the cartridge on a regular schedule based on stocking density and observed water quality; higher bioload and fine particulates may require more frequent changes. When possible, avoid rinsing the cartridge under tap water to preserve beneficial bacteria—use aquarium water for light rinsing. Monitor flow rate and water clarity after installation to confirm proper seating and compatibility with the filter unit.
