About the Rhino Hobby Filter
Features a swappable bottom and duct coupler. Turn the filter around every 8–12 weeks to even out wear and get the full 9–12 month expected lifespan out of it.
Which Size Do I Need?
Work out your grow space volume in m³ (Width x Length x Height), then multiply by 60 for the air movement needed per hour to refresh the room every minute, then by 1.5–2 to account for ducting bends and heat. It's generally better to over-spec your fan and dial back the output with a controller — running a fan at 100% around the clock shortens its lifespan, so 60–80% is a healthier long-term target and leaves you room to scale up later.
