Who This Is For

  • You are rotating fresh filters after every cycle because airborne contamination is the biggest threat to your harvest.
  • You are outfitting a standard 6 inch fan because you need to block spores without choking your intake air exchange.

What We Found

  • These filters have the right density to catch tiny particles without making your inline fan struggle for air.
  • We like how the PET fibers hold their shape even in the high humidity environments required for the crop.
  • Swapping these out after every cycle is the cheapest insurance you can buy against a total crop failure.

What Users Say

  • Users who switched to these filters report fewer contamination issues compared to using open intakes.
  • Growers using 4 inch fans found these easy to secure with standard clamps without any messy air leaks.
  • Buyers who replace these every cycle say they stopped worrying about outside spores drifting into their clean tent.
