Air Filtration for Modern Data Centers.
From enterprise rooms to hyperscale halls. MERV 13A through HEPA, ASHRAE 241 ready, ISO 16890 classified, with biodegradable and OEM-compatible options. All built in the United States.
Three things data center filtration has to get right.
Energy efficiency
Low and stable differential pressure protects fan power and improves PUE across the filter's service life.
Compliance
ASHRAE 241-ready MERV 13A filters tested to ASHRAE 52.2 Appendix J. Aligned with ISO 16890 classifications.
Sustainability
Biodegradable media and recyclable frames cut landfill waste without compromising performance.
Match the MERV rating to the risk.
MERV ratings climb as the particulate threat tightens. The right rating balances filtration efficiency against pressure drop and energy cost.
Mechanically efficient.
Predictably consistent.
ASHRAE 241 requires filters that perform without relying on a temporary electrostatic charge. Our MERV 13A line is tested per ASHRAE 52.2 Appendix J with dust loading, so the efficiency you specify is the efficiency you get throughout the service life. ISO 16890 alignment makes our HVAC line straightforward to spec internationally.
Enterprise, colocation, hyperscale, edge, modular, and cloud.
Different scales, different airflow profiles, different cost models. Our product mix covers all six.
Enterprise
Private data centers supporting a single organization.
Multi-Tenant / Colocation
Organizations leasing space and equipment from a shared facility.
Hyperscale
Facilities with up to 5,000 servers and 500 cabinets.
Edge / Micro
Smaller centers placed so computing happens closer to the data.
Container / Modular
Deployed on construction sites or in disaster-recovery scenarios.
Cloud
Storage, computing, and application hosting delivered over the internet.
Data center filtration, answered.
Seventeen questions we get from facility, sustainability, and operations leads, with our straight-from-the-engineering-floor answers.
What is ASHRAE Standard 241?
ASHRAE 241 is the standard for control of infectious aerosols. It requires mechanically efficient filtration that performs predictably over time, without relying on a temporary electrostatic charge.
What defines a MERV 13A filter under this standard?
MERV 13A filters are tested per ASHRAE 52.2 Appendix J, which includes dust loading to confirm filtration stability throughout the service life. They must maintain consistent efficiency without relying on electrostatic charge.
Why are electrostatic filters no longer acceptable for BACT?
Electrostatic filters rely on a temporary electric charge that diminishes in use, resulting in efficiency loss. ASHRAE 241 requires mechanically efficient filters that perform predictably over time.
Do Braden filters meet ASHRAE and ISO standards?
Yes. Our products align with ASHRAE guidelines for data centers and ISO 16890 classifications.
Can Braden filters fit existing OEM housings?
Yes. We offer OEM-compatible V-cell and cartridge sizes plus custom options, all made in the USA.
How do filters affect data center energy efficiency?
Filters with low differential pressure lower fan power and improve PUE. Long-life media also reduces maintenance and change-out frequency.
How does switching to MERV 13A affect energy use and HVAC load?
Properly selected MERV 13A filters, especially nanofiber media, can reduce resistance and extend service life, mitigating energy consumption. Evaluate performance based on pressure drop and air handling unit compatibility.
What are the benefits of nanofiber-based MERV 13A filters?
Our nHIBIT nanofiber MERV 13A filters provide high submicron efficiency at low pressure drop, which leads to better airflow, energy savings, and fewer filter changes, with consistent performance in dynamic HVAC environments.
What is the nanofiber media used in this application?
Nanofibers offer a very high surface area-to-volume ratio and excellent porosity. The nanofibers we use contain no PFAS chemicals.
What is the total cost of ownership (TCO) for filters?
TCO combines energy (ΔP), filter price, lifetime, labor, and disposal. Low-ΔP, long-life media typically reduces TCO.
What types of air filters are best for data centers?
Data centers typically use MERV 13 to MERV 16 or HEPA, depending on risk and compliance. We offer V-cell, cartridge, nanofiber, and biodegradable options. MERV 8 and 11 are still used in some applications.
Do data centers really need HEPA filters?
Not always. MERV 15 or 16 often balances protection and energy. Choose HEPA when very fine particulate control or strict specs are required.
What are biodegradable filters, and why use them?
They use eco-friendly media and recyclable frames to cut landfill waste while maintaining airflow and efficiency, ideal for sustainability goals.
How do I know when a filter is clogged or past its life?
Track differential pressure trends and replace at your setpoint (commonly 1.5 to 2.0 in. w.g. or your site standard), or sooner if indoor air quality or airflow degrades.
Should I use washable or permanent filters in data centers?
Usually no for critical areas. Washables vary in efficiency and load dust unpredictably. Use rated, high-efficiency disposables for predictable performance.
How can I monitor particulate and gas contaminants?
Use particle counters, differential pressure trending, corrosion coupons, and targeted gas sensors to align filter strategy with measured risk.
What are the most common types of data center facilities?
Enterprise: a private data center facility supporting a single organization. Multi-Tenant / Colocation: organizations lease space and equipment. Hyperscale: up to 5,000 servers and 500 cabinets. Edge / Micro: smaller centers where computing happens closer to the data. Container / Modular: used on construction sites or in disaster areas. Cloud: data storage, computing, and application hosting services via the internet.
