Key Features to Look for When Choosing a Ductless Fume Hood

When it comes to ensuring the safety of your laboratory or workspace, selecting the right fume hood is of paramount importance. Ductless fume hoods have gained popularity for their versatility and cost-effectiveness in various settings. However, not all ductless fume hoods are created equal, and choosing the right one requires careful consideration of key features. In this blog, we'll explore the essential features you should look for when selecting a ductless fume hood.

1. Filtration System:

The heart of any ductless fume hood is its filtration system. Look for a fume hood that features high-quality, efficient filters. HEPA (High-Efficiency Particulate Air) and/or activated carbon filters are commonly used in ductless fume hoods. HEPA filters trap particulate matter, while activated carbon filters capture and neutralize gases and vapors. Ensure that the filtration system is appropriate for the specific chemicals and substances you'll be working with.

2. Filter Monitoring and Replacement:

A good ductless fume hood should have a filter monitoring system that alerts you when it's time to replace the filters. Timely filter replacement is crucial to maintaining a safe working environment. Some systems even offer real-time monitoring and data logging capabilities, which can be valuable for compliance and record-keeping.

3. Airflow Control:

The ability to control airflow is essential for adjusting the fume hood's performance to different applications. Look for a fume hood that offers variable airflow control, allowing you to optimize the face velocity based on your specific needs. This not only enhances safety but also improves energy efficiency.

4. Safety Features:

Safety should always be a top priority. Seek a ductless fume hood with safety features such as airflow alarms, audible and visual alarms for filter saturation, and automatic sash closure options. These features provide added protection for users and the surrounding environment.

5. Noise Level:

Consider the noise level of the fume hood, especially if it will be used in a quiet laboratory environment. Some ductless fume hoods are designed to operate quietly, ensuring minimal disruption to the workspace.

6. Size and Configuration:

Select a fume hood that suits your workspace and workflow. Ductless fume hoods come in various sizes and configurations, including benchtop, floor-mounted, and portable options. Choose one that fits your laboratory layout and allows for comfortable working conditions.

7. Ease of Installation and Mobility:

Ease of installation and mobility are practical considerations. Some ductless fume hoods can be easily moved or relocated within the laboratory, providing flexibility in workspace utilization.

8. Certification and Compliance:

Ensure that the fume hood complies with relevant safety standards and regulations in your area. Look for certifications such as ANSI/ASHRAE 110, which assesses the performance of laboratory fume hoods.

9. Cost of Ownership:

Consider the total cost of ownership, which includes not only the initial purchase price but also filter replacement costs, energy consumption, and maintenance expenses. A well-designed fume hood can offer long-term cost savings.

10. Manufacturer Reputation and Support:

Choose a fume hood from a reputable manufacturer known for quality and customer support. Research customer reviews and inquire about warranty and service options.

In conclusion, selecting the right ductless fume hood involves careful evaluation of its filtration system, monitoring capabilities, airflow control, safety features, noise level, size, and compliance with regulations. Taking the time to consider these key features will help you make an informed decision that promotes safety and efficiency in your laboratory or workspace. Remember that investing in a high-quality ductless fume hood is an investment in the well-being of your team and the success of your research or processes.
