Mars Hydro Inline Duct Fan and Carbon Filter

Yes, the 4-inch fan with 205 CFM airflow is well-suited for small to medium-sized grow tents, such as 2x2 or 3x3 setups. It provides enough power to cycle the air effectively while maintaining the necessary negative pressure for odor control.

The fan is rated at 28 dBA, which is exceptionally quiet for this type of equipment. While you will hear a gentle hum at full speed, it is generally unobtrusive and comparable to a standard household fan.

The lifespan of the Australian activated charcoal filter depends on your humidity levels and the intensity of your grow. Typically, you can expect the filter to last between 12 to 18 months before the charcoal becomes saturated and requires replacement.

Absolutely. The included variable speed controller allows you to dial in the airflow precisely. You can lower the speed during the seedling stage to prevent drying out the environment and increase it during the flowering phase to manage heat and humidity more aggressively.

Yes, the kit comes as a complete package, including the necessary hanging straps and clamps. You will have everything you need to mount the fan and filter to your tent's support poles right out of the box.
