Our air cleaners are suitable for a wide range of applications, including:
• General commercial and industrial use
• Welding, grinding, and fabrication environments
• Woodworking shops and sawdust control
• Cigar lounges, tobacco bars, and smoking areas
• Plasma cutting and metalworking operations
• Environments with light to heavy odors and VOCs
• Clean rooms and sterile manufacturing
• Healthcare facilities
• Spaces with heavy particulate loads

View our case studies to see how Blue Ox has improved the air quality in businesses across these application types.

Choose based on:
• Required airflow (CFM rating)
• Type of contaminants (dust, smoke, odors, welding fumes, etc.)
• Space size
• Specific application (general use, odor control, clean room, heavy particulate)

Each product is designed to meet specific needs. Our team can help you choose the best solution for your workspace. Refer to our model comparison chart to match your needs with the appropriate unit or contact our sales team. With over 40 years of experience in the air filtration industry, we're here to help.

General use: Includes a pleated pre-filter and a pocket bag filter. Suitable for dust or smoke without odors.
Lite odor control (CF): Adds a 2" charcoal afterfilter to the general setup. Good for light odors.
Extra odor control (CC): Uses a 95% pocket bag filter and a larger Carbon Module. Ideal for heavy odors and VOCs, including cigar smoke and industrial fumes.
Clean room (HE): Includes a HEPA afterfilter for the highest level of air cleaning, suitable for sterile environments and healthcare facilities.

CFM ratings across our product line range from 825 to 7,600. Higher CFM indicates more air processed per minute. For example, the OX1100 processes 1,100 CFM, the OX2500 handles 2,500 CFM, and the OX3500 is our most powerful unit, designed for large-scale industrial environments. Our systems are engineered to perform up to eight air exchanges per hour, delivering medical-grade air quality to your space.

See the full breakdown on our model comparison chart.

Our systems use various combinations of:
• Pleated pre-filters (1" or 4")
• Pocket bag filters (65% or 95% efficiency)
• Carbon filters or modules
• HEPA filters
• Wrap-around filters

The sound levels of our air filtration systems range from 48dB to 82dB when measured at a distance of 5 feet, typically on their highest settings.

To put this into perspective:
• 40–50dB is comparable to a quiet library or a refrigerator hum.
• 60–70dB is similar to normal conversation or an air conditioning unit.
• 70–80dB is like a vacuum cleaner or a busy street.
• 80–90dB is equivalent to a food blender or heavy traffic.

Because most Blue Ox units are designed to hang from the ceiling, the perceived noise level at floor level is typically lower than the measured rating. When choosing a system, consider your environment and any applicable noise restrictions. If noise is a concern, our team can help you identify a quieter configuration.

A HEPA filter is a high-efficiency particulate air filter that removes 99.97% of particles. It's necessary in clean room environments, hospitals, and sterile manufacturing settings where the highest level of air purity is required. Blue Ox HEPA-equipped units (HE series) are ideal for these applications.

Wrap-around filters are low-efficiency pre-filters designed to extend the life of the main pre-filter in applications with large particulate or high particulate loads. They can be cleaned rather than replaced, increasing the overall system efficiency and lowering your total cost of ownership.

Replacement filters for all Blue Ox units are available directly through our website. Visit our Buy Filters page to find the right filters for your model. If you need help identifying the correct filters, call us at (866) 455-2135 or contact our team online.
