Chalk dust, mold, and chemical fumes were recirculating through an enclosed climbing environment. CleanLeaf OX3000 units now exchange the gym's entire air volume eight times per hour, reducing contaminants by 95%.
Altitude Gym, like all indoor climbing facilities, faces a set of air quality challenges that don't apply to most commercial spaces. Climbing gyms are exclusively indoor, and several factors stack up inside that envelope at once — chalk dust, mold and mildew, chemical exposure, and outdoor pollution drawn in from the surrounding area.
Chalk is the most visible of these, but it isn't the only one, and a system that handles only dust leaves the rest circulating. Moisture from sweat and showers feeds mold growth, while cleaning products and equipment maintenance add chemical fumes to the same enclosed air volume.
For a facility whose members are working at physical effort — and therefore breathing hard — maintaining air quality matters for the health and safety of climbers and staff, for comfort and performance, for compliance with indoor air quality standards, and for keeping the space somewhere members want to return to.
CleanLeaf OX3000 air filtration systems — formerly branded as Blue Ox Air Cleaners — were strategically installed throughout the climbing gym to capture chalk dust alongside the other contaminants sharing the same air.
By drawing air through a series of filter stages, the systems reduce 95% of contaminants while exchanging the facility's entire air volume eight times per hour, capturing and controlling chalk dust, mold, mildew, and other pollutants in the same passes.
The OX3000 uses a T-Style airflow pattern, with inlets on both sides and exhaust from the center — an arrangement that maximizes coverage across climbing areas from a single mounting point, which matters in a building where walls, anchors, and fall zones limit where equipment can go.
A dual set of micro-glass disposable filters gives the unit greater filter area and lets it operate at reduced static pressure. That lower airflow-to-filter ratio means higher efficiency and longer filter life — useful in a room where chalk never stops being generated.

High-capacity air cleaner with T-pattern airflow, built for dust and smoke control across wide open spans.
The OX3000 installation delivered improvements across every contaminant the facility was dealing with, rather than solving the visible problem and leaving the rest.
Chalk dust is now controlled throughout the climbing areas, and the same multi-stage filtration reduces mold, mildew, and chemical fumes by 95% in the process. Eight air changes per hour keeps that standard consistent even through peak climbing hours, when the most chalk is in the air and the most people are breathing it.
For Altitude, the outcome is a healthier environment for climbers and staff, better comfort and performance for members, and materially lower health and safety risk from airborne pollutants.
What made this installation work is what makes the approach right for training facilities generally.
Unlike single-purpose systems, multi-stage filtration tackles chalk dust, mold, mildew, chemical fumes, and outdoor pollution in the same passes.
Chalk dust is exceptionally fine and persistent. The dual micro-glass configuration provides the filter area needed to capture it effectively.
A lower airflow-to-filter ratio and reduced static pressure mean filters last longer and get changed less often, lowering running costs.
Clean air isn't only a compliance matter. It's what makes members want to climb — healthier climbers, better performance, higher satisfaction.
