Air Filtration for Multisport Training Facilities

Training environments generate more than energy — they produce airborne chalk dust, odors, and fine particulate that can affect breathing, visibility, and overall comfort.

CleanLeaf air cleaning systems are engineered to capture suspended dust and control odor at the source, helping maintain clearer air during intense training sessions.

A gym is the one commercial space where everyone in the room is deliberately breathing as hard as they can. The same air that a person would barely notice sitting still gets pulled down several times faster by someone mid-route or mid-set.

With proper unit placement, our systems continuously cycle the air through high-efficiency filtration — clearing what training kicks up before it recirculates through the room.

Climbing Gym Case Study

Clearing Chalk Dust From the Training Floor

Altitude Gym had chalk dust, mold, and fumes recirculating through an enclosed climbing environment. CleanLeaf units now filter the entire air volume 8× per hour, capturing 95% of contaminants.

What Training Puts Into the Air

Four issues build in an enclosed training space, and the room's own activity keeps putting them back.

Particulate

Chalk Dust

Chalking up, brushing holds, bag slaps, and falls onto mats put fine chalk back into the air all session. It never really settles — the room keeps re-launching it.

Biological

Mold in Humid Spaces

Sweat, showers, and enclosed volumes raise humidity, and a warm damp building with limited air movement is where mold finds its opening.

Odor

Gear, Mats & Body Odor

Shoes, pads, rental gear, and upholstered mats hold odor and release it continuously. It's the single most common thing members mention in reviews.

Fumes & VOC

Off-Gassing From Surfaces

New flooring, urethane holds, foam padding, and adhesives release compounds into an enclosed space — strongest after a reset or a build-out.

Everyone here is breathing hard

This is what separates a gym from every other commercial space. Air that a seated person would barely register gets drawn in far faster and deeper by someone working at effort — so the same airborne concentration delivers a much larger dose to the people you're selling memberships to.

How It Works

CleanLeaf and Blue Ox units hang from the ceiling or structure and run independently of your HVAC — no ductwork, and no loss of the heating and cooling you're already paying for in a building that's expensive to condition.

Units work together to create a circular air pattern through the space. As air flows through the high-efficiency filters, particulate is captured and the cleaner air is handed off to the next unit, which reduces it further. Carbon stages address the odor compounds that particulate filters can't.

At Altitude Gym this approach filters the facility's entire air volume eight times per hour, capturing 95% of contaminants — enough to keep the air clear through the most demanding sessions.

Recirculating beats exhausting in a gym. Venting hard enough to clear chalk means replacing conditioned air continuously, in a tall building with a lot of volume to heat. Cleaning the air already inside avoids the drafts and the utility bill both.

Placement makes the difference. Climbing walls and training floors have tall, open volumes where chalk drifts well above head height before coming back down. Units set to establish a continuous circular pattern intercept it rather than waiting for it to settle onto mats and holds.

Each unit has a specific catch and throw distance that determines optimal spacing. Our team can help you design a configuration around your wall heights, fall zones, and traffic patterns.

Clean Air

✓ Clearer air through peak sessions

Chalk is fine and persistent, so pre-filters do real work here. Keeping them clean is what protects the media behind them and holds performance through your busiest evenings.

Recommended Systems for Training Facilities

Choose based on ceiling height and whether chalk, odor, or humidity is driving the project. All models use standard-sized high-efficiency filters to keep running costs low.

OX1100 — Chalk Dust, Studios & Training Rooms

For weight rooms, functional training studios, gymnastics floors, and smaller bouldering spaces. With no carbon or HEPA stage taking up room, it devotes maximum filter area to particulate — and the washable foam pre-filter is doing the heavy lifting against chalk, protecting the bag filter behind it.

OX3000 — Chalk Dust, Climbing Walls & High Volumes

Lead walls and tall bouldering rooms hold a lot of air, and chalk drifts well above head height before it comes back down. The OX3000's T-style airflow draws through inlets on both sides and exhausts from the center, covering a wide span from a single mounting point — which matters when mounting options are constrained by walls, anchors, and fall zones. Larger facilities can step up to the OX4000, OX4500, or OX7000.

OX2500D-CF — Chalk & Odor Together

Gear smell is what shows up in reviews, and it isn't a dust problem — particulate filters can't touch it. This configuration pairs high-volume particulate capture with a carbon stage, handling chalk and odor in the same pass. It's also the right answer after a wall reset or build-out, when new holds, padding, and adhesives are off-gassing hardest.

CL2500D-CCPHE — Mold, Odor & Particulate in One Pass

Our climbing gym case study involved chalk dust, mold, and fumes at the same time — which is typical of an enclosed, humid, heavily used facility. This configuration stacks a carbon stage ahead of HEPA media, capturing 99.97% of particles at 0.3 microns while the carbon works on odor and off-gassing. It's the most complete build for a gym where all three problems arrived together.

Quick Answers to Common Questions

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.
