VIVOSUN Smart Air Filtration PRO S4 Kit 4in - Smart Ventilation

In this review the VIVOSUN Smart Air Filtration PRO S4 Kit 4' is evaluated for home growers and small-scale hydroponic setups; the bottom line is that it bundles smart control, strong airflow, and serious odor removal into a single, easy-to-install kit. The reviewer found it especially useful for growers who want remote monitoring and precise environment control because the GrowHub E42A provides WiFi app access and integrated temp and humidity sensing while the AeroZesh S4 fan moves a robust 208 CFM quietly. For anyone who needs reliable ventilation and odor control in a compact package, this kit delivers.

Key Features

• Complete kit: Includes an AeroZesh S4 4 in inline fan, GrowHub E42A controller, 4 in carbon filter, and 4 ft of foil ducting so users get a matched ventilation system without extra buying.
• Adjustable airflow: The AeroZesh S4 produces up to 208 CFM with PWM control so growers can dial fan speed to match tent size and airflow needs.
• Quiet operation: At about 39 dB the mixed-flow, EC-motor design keeps noise low, making it suitable for indoor grow rooms and home environments.
• Remote environmental control: The GrowHub E42A provides WiFi app access, a built-in temp and humidity gauge and a probe to monitor conditions and automate fan speed.
• High-performance carbon filter: The 1200+ IAV RC 412 Australian virgin charcoal bed at 38 mm thickness offers strong odor adsorption for better stealth and air quality.
• Durable ducting & clamps: Aluminum ducting with a PET thermoplastic central layer and stainless clamps helps prevent air leaks and resists tearing during install.

Who It's For

This kit suits hobbyist and small commercial growers who need an integrated, smart ventilation system for a single grow tent or a compact grow room. It is ideal when odor control matters and when remote monitoring or automation is desired, since the GrowHub controller reports temp and humidity and can adjust fan speed accordingly.

Those with very large rooms, multi-tent installations or who require ultra-high CFM should look for larger inline fans or modular multi-fan systems; likewise, growers who prefer fully passive odor control methods without electronics may find parts of the kit more than they need.

Pros & Cons

Pros

• Integrated package saves time and ensures matched components for ventilation and odor control.
• WiFi and app control via the GrowHub E42A makes remote monitoring and automation straightforward.
• Quiet but powerful AeroZesh S4 fan gives adjustable 208 CFM airflow while remaining relatively unobtrusive at 39 dB.
• Premium RC 412 Australian charcoal provides effective odor reduction and reversible mounting options.

Cons

• The 4 in fan and 208 CFM rating are best for small tents; larger grows will need higher capacity equipment.
• The kit includes a single probe for sensing; multi-point monitoring would be required for larger or multi-zone setups.
