The NuTone LS80LF and LS100LF are advanced ventilation fans tailored for modern residential needs. With an emphasis on improving indoor air quality, these models bring cutting-edge technology and thoughtful design to any home environment.

The LS80LF boasts an impressive airflow capacity of 80 CFM, making it ideal for smaller to medium-sized bathrooms or laundry rooms. This model operates quietly at a mere 1 sones, ensuring that homeowners can enjoy a peaceful atmosphere, whether they're using the bathroom or engaging in chores. The LS100LF, on the other hand, offers a more powerful airflow of 100 CFM, catering to larger spaces while still maintaining a whisper-quiet operation of 0.7 sones.

One of the standout features of both models is the integrated LED lighting.

The LS80LF and LS100LF are designed with a sleek, unobtrusive appearance, allowing them to seamlessly blend into the decor of any bathroom.

Both models also incorporate NuTone’s innovative TrueSeal technology, which minimizes air leakage compared to traditional fans. This feature helps to maintain energy efficiency by preventing conditioned air from escaping. The fans come with a durable housing that is constructed from high-quality materials, designed to withstand the humid conditions typical in bathrooms and laundry areas.

Installation is simplified due to the fan’s easy-to-follow instructions, and they fit into standard ceiling cutouts, making them a great choice for either new construction or retrofitting in existing homes.

Lastly, the LS80LF and LS100LF come with a flexibility of controls. The fans can be wired to a wall switch or paired with a humidity or motion sensor to enhance user convenience. Overall, the NuTone LS80LF and LS100LF are exemplary models that prioritize performance, efficiency, and user-friendliness, making them a smart investment for any home focused on better air quality and comfort.
