Phresh Intake Filter for Grow Tents and Grow Rooms

Clean Air In, Pests and Spores Out

Most growers filter the air leaving the tent and forget about the air coming in. The Phresh Intake Filter mounts at the entry point of your intake ducting and removes 98.7% of airborne contaminants before they ever reach your canopy, including mould spores, dust, pollen and insects. It uses patented pleated nano-carbon felt to do it while still holding over 90% airflow efficiency, so extraction stays balanced rather than choked. This is not an inline filter, it is a drum that sits on the end of the duct.

Key Benefits

• 98.7% filtration: traps airborne pathogens, spores and pests at the source
• Airflow you keep: maintains 90%+ of your intake flow rate, so negative pressure stays where you set it
• Pleated nano-carbon felt: far more surface area than a flat mesh sock
• Protects your carbon filter: reduces the dust load reaching your extraction filter and extends its working life
• Lightweight and recyclable: easy to handle, easy to swap out
• Direct duct fit: slides straight onto standard intake ducting, no bracketry needed

Stopping Mould and Pests at the Door

Thrip, mite and fungus gnat problems usually start as something drawn in through an unfiltered intake, and mould spores land on damp buds long before you spot them. Filtering incoming air cuts that route off, which matters most in high humidity and late flower when dense heads are vulnerable. Cleaner air also means less dust on leaves, so light reaches the canopy properly.

How to Use

Remove the outer wrap, slide your intake ducting over the flange, secure it with a duct clip and seal the joint with tape for the best result. Match the filter size to your fan and duct size so you do not restrict flow. Expect a working life of 3 to 12 months depending on how dusty your environment is, and replace it when flow starts to drop.
