  • Whisper Internal Filters: 20i, 40i
  • PF Series Power Filters: PF20, PF30, PF40, PF60

Six-in-one filtration for healthier tank water

  • Dual-sided mesh traps debris and waste, helping maintain a pristine tank surface
  • 50% extra activated carbon to help reduce odors and reduce yellowing in the water
  • Zeolite supports stable pH balance, contributing to a steadier aquatic environment
  • Ceramic media offers a pathway for heavy metal absorption, promoting safer water
  • Added Activated Alumina targets algae-feeding nutrients, supporting clearer glass surfaces
  • All layers work in harmony to deliver consistently clean water and lower maintenance in between cleanings

New upgrade: Activated Alumina media

The enhanced Activated Alumina media is designed to address nutrients associated with algae growth. This upgrade may help keep tanks looking clearer and more vibrant, while supporting a healthier habitat for your fish and plants.

Easy setup and reliable care

  • Pre-assembled for instant use—just place into your Whisper or compatible filter
  • Standard cartridge size compatible with a wide range of filters
