The Interpet PF Internal filter range is the most advanced and comprehensive filter available. It has been designed to give highly effective low maintenance filtration, so you can provide ideal conditions for your aquarium fish, plants and coral to thrive, with very little work.

They are extremely simple to install and use, and offer your fish a cleaner, healthier aquarium with triple action filtration: containing 2 foams for biological and mechanical filtration as well as a carbon foam for chemical filtration, to remove toxins and odours from the water.

All models except for the PF Mini feature the unique patented Aqua Valve. The Aqua Valve allows waste materials to pass into the filter, but prevents them from dumping back into the aquarium. Therefore, unlike almost every filter on the market, the Interpet PF filters allow the consumer to simply turn the filter off, and remove the body for cleaning, without seeing all the removed waste drop back into their clean aquarium. 

PF Mini: The PF Mini is designed to be trouble-free and comes with a flow director and fixing cradle, and also includes 2 foams for mechanical and bio filtration and a separate carbon foam.

PF1: The PF1 filter is far more comprehensive, and includes a foam carrier, flow control, head rotation, venturi and Interpet's unique, patented Aqua Valve. For filter media, the PF1 contains plain foams and a carbon foam.

PF2, PF3, PF4: The larger filters offer all the features of the PF1, but in addition they have a separate Biomedia chamber.This is housed in the head unit and contains Biomedia.The huge surface area of this media provides superior biological filtration.Additionally it allows the filter foams to be cleaned more thoroughly, as doing so will not affect the biological effectiveness

Please note the capacity guidelines should be used as a guide only. For marine aquariums, or where large messy fish like goldfish or cichlids are kept, this will require a higher filtering capacity so you should always choose the next size up from the table. More is always better!
