When it comes to maintaining clean, breathable air in our workspaces, having an effective and reliable air filtration system is essential. That’s why we decided to put the JET Portable Air Filtration System (Model AFS-850) to the test. Designed to capture dust particles as small as 1 micron with its high-efficiency MERV 15 filter, this unit promises powerful filtration at an remarkable 850 cubic feet per minute (CFM) airflow. Over the past few weeks, we’ve used the AFS-850 in various workshop settings, appreciating features like its automatic air quality sensor that adjusts fan speed based on dust levels, a quiet operation that never exceeds 68 decibels, and a convenient filter replacement indicator. In this review, we’ll share our hands-on experience with the portability, performance, and overall usability of the JET AFS-850, helping you decide if it’s the right air filtration solution for your needs.
Overview of the JET Portable Air Filtration System and What We Noticed

We were impressed by how efficiently this air filtration system cleans the air in areas with intense dust generation, filtering particulates as small as 1 micron. its MERV 15 filter captures dust ranging from 0.3 to 10 microns, which means it’s capable of trapping a wide spectrum of harmful airborne particles before they reach our lungs. One feature that stood out to us is the built-in automatic air quality sensor, which intelligently ramps the motor speed up or down based on detected dust levels-this not only improves air quality but also conserves energy and reduces noise.Speaking of noise, even at its peak airflow capacity of 850 CFM, the system operates at a maximum sound level of just 68dB, making it relatively quiet in a workshop or garage habitat.
We also appreciated the thoughtful design elements that enhance usability.Weighing only 34 pounds, it’s easy to move around, and the 15-foot power cable provides versatility on placement. The LED display is luminous and clear, showing real-time data including the filter status indicator-reminding us when it’s time for a replacement to maintain optimal performance. Additionally, the impellers have been fine-tuned using computational fluid dynamics, contributing to efficient airflow and quieter operation. it’s a well-rounded system that balances power, convenience, and smart automation, making airborne dust management a much simpler task.

Key Features That Make This Air Filtration System Stand Out

One of the most impressive aspects of this unit is its high-efficiency MERV 15 filter, capable of capturing dust particles ranging from 0.3 to 10 microns. this means it effectively traps even the smallest airborne contaminants, protecting our breathing air in environments where dust generation is constant. The built-in dust particulate sensor further elevates its performance by automatically adjusting the filtration speed based on the air quality. When dust levels rise, the system ramps up to its max airflow capacity of 850 CFM, then quietly reduces power as conditions normalize – ensuring both clean air and energy efficiency.
Portability and user convenience also set it apart. Weighing just 34 pounds and featuring a bright LED display, it’s easy to monitor performance and filter status at a glance.The impellers have been finely tuned with computational fluid dynamics to minimize sound levels, keeping noise under 68dB even at full speed – perfect for workspaces where concentration matters. Additional thoughtful touches include a 15-foot power cable to maximize placement flexibility and a filter replacement indicator, so we never have to guess when maintenance is needed.
