VIVOHOME Bathroom Exhaust Fan 110 CFM

If your main goal is to clear shower steam without remembering to switch a fan on and off, this VIVOHOME bathroom exhaust fan adds automatic humidity sensing to a 110 CFM unit. It also offers a manual mode, so you can choose steady operation instead. The ceiling retrofit format is intended for a 10.2-inch opening and the package includes ducting components, but the fan does not include a light. That makes it a more feature-focused choice than a basic manually controlled fan, with a few fit and function details worth considering.

Quick overview

The fan uses a brushless EC motor rated at 12.5W, and the maker lists a 30,000-hour lifespan. In manual mode, it runs at 110 CFM, in humidity-sensing mode, it switches on at 55% humidity and off at 50%. The airflow is also designed to adjust to resistance from duct bends, dust buildup, or increased static pressure. Those features may suit a bathroom where moisture levels change during showers, while a simpler fan may make more sense if you only need basic manual ventilation.

The maker lists 1 sone operating noise and says the fan is intended for rooms up to 129 square feet. Keep in mind that those are stated performance details, not a guarantee that it will feel equally quiet or clear steam equally quickly in every room and duct setup. It is a fan-only unit, so it cannot replace a ceiling fan with an integrated light.

Best use cases

This setup is aimed at small to medium bathrooms, laundry rooms, and toilets where automatic ventilation is useful. Picture finishing a shower and leaving the room: humidity mode is designed to turn the fan on as the level reaches its trigger, then shut it off once humidity falls to the listed threshold. You can also select manual mode when you want continuous airflow rather than sensor-based operation.

The housing measures 8.9 × 8.9 × 5.7 inches and is made to fit standard 10.2 × 10.2-inch ceiling openings. A white 11.8 × 11.8-inch panel covers the opening, and the unit is compatible with 4-inch flexible ducting. Check that those dimensions and your existing duct arrangement suit the installation before choosing it, the retrofit format does not mean every ceiling or duct layout will be a match.

Tips for day-to-day use

Choose between manual and auto humidity sensing with the switch inside the panel. In a bathroom, the automatic mode is the more hands-off approach, manual mode gives you a straightforward way to run the fan when needed. The constant-airflow feature is intended to help maintain airflow as duct resistance changes, but it does not remove the need for a suitable duct path.

The package includes an aluminum duct, ABS vent, extended power cord, backdraft damper, and a placement template. Installation is described as tool-free, with brackets and latches used to secure the unit. A solid pick if the existing ceiling opening matches and you want humidity-triggered operation. Not the best choice if your project requires a light or a fan sized for a room beyond the stated coverage.

Questions before you buy

Does it have a light? No. The product information specifies a fan-only unit with no light feature.

What happens in humidity mode? The fan is specified to turn on at 55% humidity and off at 50%, manual mode runs at a steady 110 CFM.

What ducting does it use? It is listed as compatible with 4-inch flexible ducting, and an aluminum duct is included.

When it makes sense

Choose this model if automatic humidity control, a retrofit opening, and the included duct components fit your bathroom project. The humidity thresholds and manual mode offer more control than a basic on/off fan, while the stated 110 CFM and room coverage give you concrete sizing details to compare against your space. According to the maker, it is intended for rooms up to 129 square feet, for a larger room, a different capacity may be more appropriate. If you need integrated lighting or your ceiling opening and duct setup do not match the listed dimensions, look for a unit designed around those requirements instead.
