Choosing an Air Filtration Kit
The right
VIVOSUN air filtration kit comes down to duct size (tent footprint) and controller tier (manual vs smart). The kit format saves the buyer from sizing the fan and filter separately, then sourcing ducting and clamps. Everything ships pre-matched in one box.
Kit Sizing
Why a Kit vs Building Yourself
The kit removes three sizing decisions: fan CFM, filter CFM rating, and ducting pressure drop. VIVOSUN pre-matches the fan to a filter with at least 15-20 percent CFM headroom, which is the engineering buffer that keeps real-world airflow high. Buying separately works if you already understand the math; for first-time builders, the kit format is a meaningful time-saver. The Smart kit upgrade adds Wi-Fi control via the E42A; the Smart Pro kit ties into the full GrowHub ecosystem.

Frequently Asked Questions
What's in a VIVOSUN air filtration kit?
An AeroZesh inline fan, a matching VIVOSUN carbon filter, 8 feet of flexible ducting, two duct clamps, two rope-ratchet hangers, and a controller (E12 dial or E42A Wi-Fi depending on the kit tier). The kit covers everything needed for a working exhaust path from the tent to the outside vent or filter discharge.
Do I need a kit or can I buy parts separately?
Both work. The kit saves time on sizing decisions because VIVOSUN pre-matches the fan and filter CFM ratings. Buying separately gives more flexibility if you want a specific filter from another brand or you already own ducting. For a first build, the kit is the simpler path.
Is the kit fan and filter sized correctly together?
Yes, VIVOSUN spec-matches the kit so the filter CFM rating exceeds the fan's max draw with 15-20 percent overhead. This buffer compensates for ducting bends and pressure drop, keeping real-world airflow at the tent inlet close to the fan's nameplate rating. Mismatched fan/filter pairings are the most common reason DIY ventilation builds underperform.
Does the smart kit work with GrowHub?
The Smart Pro kit fans (T-series AeroZesh) plug directly into a GrowHub Smart Controller via the UIS connector. The smart kit's bundled E42A controller can be replaced by a GrowHub when you build out the full ecosystem. The basic E12 dial on the entry-tier kit doesn't integrate with GrowHub.
Can I use the kit for intake instead of exhaust?
Yes, but standard practice is to run the kit on the exhaust path so the carbon filter scrubs odorous tent air before discharge. Intake-side filtration is only useful for pulling clean air from a dusty environment. For odor control in a residential setup, keep the kit on exhaust.
What ducting length comes in the kit?
8 feet of flexible aluminum ducting, which covers most short-run residential setups (tent to ceiling vent or wall outlet). For longer runs, plan to source additional 8-foot or 16-foot sections separately. Each additional bend or 8 feet of ducting adds noticeable pressure drop; minimize runs where possible.
