Air Filtration for Manufacturing Dust, Powders & Odors

In pharmaceutical, food, beverage, and cosmetic manufacturing, airborne contaminants aren't just an inconvenience — they're a compliance and product integrity risk.

Uncontrolled dust, fine particulate, and airborne pollutants can compromise sterile environments, contaminate products, and expose employees to unnecessary respiratory hazards.

In powder-handling operations, the contaminant is often the product itself. Active ingredients, pigments, flour, and excipients don't stay where they're dosed — they go airborne at every transfer, weigh-out, and blend, then settle wherever the air carries them.

CleanLeaf units remove industrial-level contaminants, providing you and your team with cleaner air and a more effective production environment that upholds high standards of quality and safety.

With proper unit placement, our systems exchange the air in your space 8-10 times per hour — reducing particulate by up to 99.7% with every pass until your room is performing at its best.

Eliminating Silica Dust & Epoxy Odors at the Source

A Granite Transformations facility struggled with hazardous silica dust and strong epoxy odors that previous solutions couldn't fix. See how the OX3000 handled both.

What Production Puts Into the Air

Four contaminant types show up across regulated manufacturing. Each one calls for a different filtration stage.

Powders

Airborne Product

Active ingredients, pigments, flour, and excipients go airborne at every weigh-out, transfer, and blend — and settle wherever the room's air carries them.

Particulate

Process-Generated Dust

Cutting, grinding, milling, and finishing throw fine particulate that stays suspended long after the operation stops — silica and metal dust among the most hazardous.

Odor & VOC

Process Odors

Epoxies, solvents, coatings, and curing agents release compounds that linger in enclosed production areas and drive worker complaints.

Compliance

Cross-Contamination

Residual airborne material from one run reaching the next is a batch record problem, not a housekeeping one — and it's the hardest kind to trace after the fact.

Changeover is the pressure point

Line clearance assumes the room is clean when the next batch starts. Anything still suspended from the previous run settles onto equipment and product after the wipe-down is signed off — which is why airborne load between batches matters as much as the cleaning procedure itself.

How It Works

CleanLeaf and Blue Ox units hang from the ceiling or structure and run independently of your HVAC — no ductwork, and no interference with existing make-up air, pressurization, or process exhaust.

Units work together to create a circular air pattern through the space, much like supply and return vents in an HVAC system. As air flows through the high-efficiency filters, particulate is reduced by up to 99.7% per pass — then handed off to the next unit, which reduces it further.

This cycle continues until the room reaches a clean air standard, with the air exchanging up to 8-10 times per hour depending on your configuration.

Ambient capture complements source capture. Hoods, downdraft tables, and local extraction catch what they're aimed at. What escapes the capture zone becomes room air — and stays there until something removes it. Ceiling units address that fraction rather than replacing your existing collection.

Where sterile conditions or product integrity are the driver, HEPA configurations capture 99.97% of particles at 0.3 microns. Where solvents and coatings are in play, carbon stages can be added to the same unit.

Placement makes the difference. Units positioned to establish a continuous circular pattern pull air away from work surfaces rather than pushing it across them. Key factors include cubic footage, ceiling height, particulate load, equipment layout, and your target air quality standard.

Recommended Systems for Manufacturing

Choose based on your primary contaminant and the cubic footage you need to turn over. All models use standard-sized high-efficiency filters to keep running costs low.

OX3000 — Dust & Powders, Production Floors As Featured in Our Case Study

The workhorse for a single production area. A dual set of micro-glass fiber filters provides substantially more filter area than a single-filter unit, and the T-style airflow pattern draws through inlets on both sides while exhausting from the center — covering a wide work area from one mounting point. This is the unit that resolved silica dust and epoxy odor at Granite Transformations after other approaches had failed.

When the contaminant load is continuous and the space is large, the OX4500 delivers half again the airflow of the OX3000. Built for demanding industrial duty including oil mist and smoke alongside dust, it's the right call for machining halls, fabrication bays, and processes running through full shifts. For spaces beyond its reach, the OX7000 extends the same approach to 7,000 CFM.

Quick Answers to Common Questions

Find quick answers to the most common questions about our services, solutions, and process.

See All FAQs

Air filtration system selection depends on:
• Room size (cubic footage)
• Air changes per hour (ACH)
• Type of contaminants (dust, smoke, mold, odors, VOCs)
• Required filtration level (bag filter %, carbon weight, HEPA, etc.)

Our team evaluates airflow dynamics and contaminant load to recommend a properly sized solution — not just a box with a fan.

Most CleanLeaf and Blue Ox models operate between ~48–66 dBA, depending on airflow setting and unit size.

Lower-speed settings and optional silencers are available for sound-sensitive environments.

Most units are plug-and-play on standard 115V power and include suspension or bracket mounting options.

For larger commercial or industrial applications, we may recommend airflow planning to optimize circulation patterns.

Filter life varies by environment and contaminant load. Typical ranges:
• Pre-filters: 1–3 months
• Carbon media: 6–12 months
• HEPA or high-efficiency bags: 6–18 months

Higher particulate or odor loads may shorten intervals.

Our systems are engineered to capture and control:
• Dust
• Smoke
• Mold and Mildew
• Odors and VOCs
• Fine particulate

Filtration stages may include pleated pre-filters, high-efficiency bag filters, HEPA media, and activated carbon depending on the application.

CleanLeaf offers a 2-year warranty covering defects in materials and workmanship for authorized distributors and end users.

To make a claim, you must get approval first. Approved claims are resolved with a replacement or credit/refund. The warranty is void if the product was misused or used outside its intended purpose.

We also provide ongoing support and access to replacement filters.
