Air Filtration for Material Storage

Airborne dust and cross-contaminants can degrade seeds, damage stored materials, and compromise the integrity of sensitive agricultural inputs.

Storage is where time works against you. Inventory sits for weeks or months, and everything suspended in the air has that entire period to settle onto it. A load light enough to ignore over a shift is a different problem over a season.

CleanLeaf systems control airborne particulates and help stabilize indoor air conditions — protecting valuable inventory and reducing the risk of contamination or material loss.

With proper unit placement, our systems exchange the air in your building 8-10 times per hour — reducing particulate by up to 99.7% with every pass, in buildings that often have no air treatment at all.

Why storage is different

Application Note

The Cost of Air You Never Treated

Most storage buildings have no HVAC and no filtration — so nothing removes what comes in through the dock doors. Talk to us about what a season of settling costs you.

What Reaches Your Stored Inventory

Storage buildings look static, but the air in them isn't. These four are how contamination gets to material that's just sitting there.

Particulate

Traffic & Handling Dust

Forklifts, pallet movement, and loading raise settled dust back into the air with every pass — putting it right back onto everything in the building.

Infiltration

Dock Doors & Outside Air

Open doors bring field dust, pollen, and road grit straight in. In most storage buildings there's nothing between that air and your inventory.

Biological

Mold & Fungal Spores

Spores landing on stored seed and organic material wait for the moisture to arrive. Long dwell times give them every opportunity to find it.

Cross-Contact

Contamination Between Lots

Materials sharing a building share its air. Treated seed, feed, and inputs stored together exchange particulate whether or not they're separated on the floor.

Exposure is dose times time

A processing room's contamination is measured in a shift. Storage is measured in months. That difference is why an airborne load that seems tolerable at a glance still ends up as visible settling, downgraded lots, and rejected material by the time inventory ships.

How It Works

CleanLeaf storage air cleaners hang from the ceiling or structure and operate as standalone systems — no ductwork, and no HVAC required. In buildings that were never designed for air treatment, they're often the only filtration present.

Units work together to create a circular air pattern through the building. As air flows through the high-efficiency micro-glass 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 space reaches a clean air standard, with the air exchanging up to 8-10 times per hour depending on your configuration.

Running between activity is the point. Storage dust comes in bursts — a delivery, a forklift run, a door left open. Continuous operation means the load raised during those events gets pulled back out during the long quiet stretches, instead of settling onto inventory.

Placement makes the difference. Units positioned near dock doors and traffic lanes intercept contamination at the point of entry, before it reaches racked or palletized material. Key factors include building size and ceiling height, rack layout, door activity, and what you're storing.

Each unit has a specific catch and throw distance that determines optimal spacing, and high-bay ceilings change that math. Our team can help you design the right configuration for your building.

Clean Air

✓ Less settling onto inventory

Units cycle air up to 8-10× per hour, running through quiet periods as well as active ones — so dust raised by a delivery or forklift run is removed before it settles onto stored material.

Recommended Systems for Storage Facilities

Storage buildings are large with high ceilings, so airflow and throw distance drive the selection. All models use standard-sized high-efficiency filters to keep running costs low.

Dust & Particulate

For warehouses, barns, and storage buildings where settling dust from traffic and dock activity is the primary concern — the most common starting point for storage.

OX3000 — Dust & Particulate, High-Bay Buildings Most Popular for Storage

Storage buildings are mostly air. High ceilings and open spans mean coverage per unit matters more than it does in a small room, and the OX3000's T-style airflow pattern — inlets on both sides, exhaust from the center — reaches across a wide footprint from a single mounting point. A dual set of micro-glass fiber filters extends service intervals in buildings where nobody's checking a gauge daily.

Where inventory is stored long enough for mold to become a real risk, a HEPA stage captures 99.97% of particles at 0.3 microns — well below the size of common fungal spores. This is the configuration for seed storage, certified lots, and organic material held through a full season, delivered at enough airflow to cover a warehouse floor.

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.
