All MAN Made Filters are designed with simplicity in mind. First and foremost the goal is to provide mechanical and biological filtration that improves water clarity and water quality. We use the heaviest polyethylene housings available. They are virtually indestructible. They are easy to clean; simply remove the filter media without disturbing the filter housing. Lifetime guarantee on all fittings, grates and housings.
Whenever possible MAN Filters incorporate plants as part of the process. Plants are vital to water quality and fish health. Harnessing the power of plants by placing them in moving water as part of the filtration system increases the nutrient uptake and leads to a healthier more beautiful water garden.
