### **Broan Losone L700 Select High Ventilation Fan: Pros and Cons**

The Broan Losone L700 Select High is a high-performance bathroom ventilation fan designed for efficient air exchange, energy efficiency, and quiet operation. Here are its key advantages:

1. **High Airflow Capacity** The L700 Select High delivers **110 CFM (Cubic Feet per Minute)** at high speed, making it one of the most powerful options in Broan s lineup. This ensures rapid removal of humidity, odors, and mold spores, which is crucial for preventing moisture-related damage in bathrooms.

2. **Energy Efficiency** It features a **dual-speed motor** (low and high) with an energy-efficient design, helping reduce electricity consumption compared to older, less efficient models. The high-speed setting is optimized for maximum airflow without excessive power use.

3. **Quiet Operation** Despite its high performance, the L700 Select High is designed to operate at **low noise levels** (typically around **1.0 Sone at high speed**), making it suitable for bathrooms where noise is a concern. This is achieved through advanced motor and blade engineering.

4. **Humidity Sensing (Optional)** While the base model does not include automatic humidity sensing, it is compatible with Broan s **humidity sensors**, allowing for automatic activation when moisture levels rise. This feature can be added later if desired.

5. **Durable Construction** The fan is built with **corrosion-resistant materials**, ensuring longevity in humid environments. The motor and housing are designed to withstand prolonged exposure to moisture without degrading.

6. **Easy Installation** Broan fans are known for straightforward installation, and the L700 Select High follows this tradition. It includes **pre-wired connections** and a **duct adapter**, simplifying the setup process for most DIYers.

7. **Good Airflow Distribution** The fan s **blade design and housing** help direct airflow effectively, reducing turbulence and improving overall ventilation efficiency.

8. **Compatibility with Common Venting Systems** It works with standard **3-inch ducting**, making it versatile for most bathroom setups. It also includes a **duct adapter** for easy connection.

9. **Warranty Coverage** Broan offers a **limited lifetime warranty** on the motor and a **5-year warranty** on the housing, providing long-term peace of mind.

10. **Aesthetic Design** The fan has a **sleek, modern look** that blends well with contemporary bathroom decor, available in **white and other finishes** to match different styles.

1. **Higher Upfront Cost** Compared to basic ventilation fans (e.g., 50-70 CFM models), the L700 Select High is **more expensive**. The price reflects its high airflow and energy efficiency, but it may not be necessary for smaller bathrooms or less humid climates.

2. **Limited Automatic Features (Base Model)** The standard L700 Select High does **not include automatic humidity sensing or timer controls**. If these features are important, you would need to purchase them separately, adding to the cost.

3. **Ducting Requirements** For optimal performance, the fan requires **properly sized and sealed ducting**. Poor ducting (e.g., sharp bends, improper sealing) can reduce airflow efficiency and may require additional work during installation.

4. **Noise at High Speed (Relative to Ultra-Quiet Fans)** While the L700 Select High is quieter than many high-CFM fans, it is **not as silent as ultra-low-noise models** (e.g., some Broan QuietCare fans). If noise is a critical concern, you may need to consider a **lower CFM fan** or a model with built-in sound dampening.

5. **Installation May Require Professional Help** While Broan fans are designed for DIY installation, **complex setups** (e.g., venting through walls, attics, or long duct runs) may require professional assistance to ensure proper airflow and prevent backdrafting.

6. **Not Ideal for Very Small Bathrooms** If your bathroom is **under 50 square feet**, a **lower CFM fan (50-70 CFM)** may be sufficient, as excessive airflow can lead to unnecessary energy use and noise.

7. **Limited Customization** Unlike some high-end ventilation systems, the L700 Select High does not offer **adjustable speed settings beyond low and high**. If you need precise control, you may need to pair it with a separate control switch.

8. **Potential for Condensation Issues** If the ducting is not properly insulated or vented to the **outside (not the attic)**, condensation can form inside the duct, leading to mold growth over time. Proper venting is essential.

9. **Weight and Bulk** The fan is **heavier and bulkier** than some smaller models, which may make installation slightly more challenging, especially in tight spaces.

10. **Dependence on Electrical Wiring** Like all fans, it requires **proper electrical wiring and a dedicated circuit** (if not GFCI-protected). Incorrect wiring can pose a fire hazard or electrical risk.

---

The **Broan Losone L700 Select High** is an **excellent choice** for homeowners who prioritize **high-performance ventilation, energy efficiency, and quiet operation** in their bathroom. It is particularly well-suited for:

- **Larger bathrooms (50 sq ft)**

- **Humid climates or bathrooms prone to mold/mildew**

- **Those who want strong airflow without excessive noise**

- **Homeowners willing to invest in long-term reliability**

- **Very small bathrooms** (where a 50-70 CFM fan suffices)

- **Budget-conscious buyers** (if cost is a major concern)

- **Those who prefer ultra-quiet operation** (in which case a lower CFM or sound-dampened fan might be better)

- **DIYers uncomfortable with electrical work or ducting challenges**

---
