The Blue Ox OX2500-HE is a ceiling-hung HEPA air cleaner for larger spaces that demand high capture efficiency. Featuring straight-through airflow and a low air-flow-to-filter ratio, it delivers strong performance and long filter life. Air moves through a pleated pre-filter and a high-capacity bag filter before finishing at a true 99.97% HEPA final filter (@ 0.3 microns).
True HEPA final: 99.97% capture @ 0.3 microns for critical environments.
3-stage configuration: pleated pre-filter → 95% bag filter → HEPA final.
Rugged 16-gauge steel cabinet with straight-through airflow and 4-way discharge.

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