PrimaKlima CarboCone CTC75 Carbon Filters

Carbocone is a brand new line of high-quality German filters. They have an innovative (and patented!) conical inner construction. Why conical? Because more air usually flows through the filter near the fan. The carbon layer is thicker on that side to account for it. If you'd like a demonstration, see the video by the manufacturer.
The new patented design allows for more effective filtration and a longer lifespan - they can last up to 3 years. The main advantages of these filters are:

  • Uses up less carbon
  • Most durable product on the market (lasts up to 30% longer than other filters)
  • Significantly more effective absorption

The Carbocone filters us CTC65 activated charcoal, the same high-quality carbon used in the Industry Line.

Carbocone filters are available in different sizes and options. Use the table below to pick the right one to fit your needs. If you'd like to talk to an expert before buying a filter, contact us at
