Whisper® Power Filters are the best-selling brand of power filters in the U.S. Appropriate for every size aquarium, they provide the three types of filtration that your aquarium needs:
Mechanical Filtration -- To remove particles such as uneaten food, bits of plants, fish waste, etc., from the water
Biological Filtration -- To provide for the growth of a colony of beneficial bacteria that will eliminate harmful toxins in the water
Chemical Filtration -- Activated carbon removes compounds that cause odors and discoloration of the water
Designed for ease of use, Whisper® Power Filters use Bio-Bag® filter cartridges for mechanical and chemical filtration. The disposable Bio-Bags® remove waste particles, discoloration and odors from aquarium water. Bio-Bags® are easy to change, making it easy to maintain clear aquarium water.
