Custom air filters engineered to meet your device specs, validation requirements, and regulatory obligations — from first prototype to full production. Whether you're developing a next-generation device or building something new from the ground up, we've developed HEPA, ULPA, activated carbon filtration solutions, and more for surgical smoke evacuators, ventilators, and a range of medical devices where performance documentation and supply reliability aren't optional.
The people who depend on these devices don't have room for filtration that underperforms. The filter itself plays a direct role in helping to protect patients and staff.
We partner with your team — design engineers, mechanical engineers, product development teams, project managers, and more — to engineer filtration that fits your system, supports your compliance pathway, and holds up under scrutiny.
Medical devices that rely on HEPA, ULPA, carbon filtration or more, carry real performance and compliance obligations. How filtration is engineered, validated, and documented directly impacts your regulatory pathway, your QA burden, and your product's credibility in the field.
Performance specs mean nothing without documented proof. We engineer filters to meet stated requirements and build the validation package to support them — so every claim you make is traceable back to tested, lot-level data.
Airflow resistance, noise, service life, and capture efficiency are properties of the complete device. We engage early in your design process to ensure the filter works within your system — not just in isolation. Our team is experienced and will collaborate with your team to address the needs and design of the full device.
Shorter lead times, predictable supply, and lot-level documentation across every unit produced. No indirect coordination. No assumptions about whether what ships matches what was validated.
Material certifications, construction records, repeatable testing protocols, and production sampling plans — all developed as part of the engineering process, not assembled after the fact.

Medical devices requiring custom air filtration span a wide range of applications — each with its own performance requirements, environmental conditions, and regulatory obligations. We've engineered filters for surgical smoke evacuators, ventilators, and powered air-purifying respirators (PAPRs), as well as patient monitors, anesthesia machines, infusion pumps, dental suction units, diagnostic imaging equipment, and laboratory instruments, all where custom air filters are critical. If your device moves air, we can engineer a filter for it. Our Engineer-to-Order process is how we bring those solutions to life — a structured, documented approach from defined requirements through prototyping, validation, and sustained production. A controlled process that scales with your program.
Whether you're evaluating new filtration suppliers, developing a new device platform, improving an existing design, or working through validation and documentation requirements — we're happy to connect for a no-pressure engineering consultation.
An exploratory conversation focused on your design goals and medical device requirements — no contracts, no pressure.
Speak directly with our sales team and engineers who understand airflow, pressure drop, filtration efficiency, and the performance demands of medical device applications.
Share drawings, specifications, or performance requirements, and we'll help identify a filtration solution that fits your system. NDA agreements are available to support confidential design discussions.
Receive guidance grounded in filtration performance, regulatory defensibility, and long-term supply reliability — not just product selection.

Our filtration capabilities give medical device OEMs the precision, documentation, and supply reliability needed to bring custom air filters from concept to sustained production.
From HEPA and ULPA filtration to activated carbon and multilayer composite designs, our U.S.-based manufacturing capabilities support the performance, traceability, and regulatory requirements of medical device applications.
Filters aren't just built, they're proven. We run HEPA and ULPA efficiency checks as needed, measure pressure drop, and tie every result back to lot data — so performance is documented, not assumed.
The pleat defines how air moves through your device. Our lines handle pleats, mini-pleats, and V-banks, producing filter packs that hit efficiency and capacity targets while fitting your design without rework.
No two medical device designs are alike. We cut pleated or layered media into precise shapes and sizes — from quick prototypes to high-volume production runs — so your filter fits the application exactly.
Seals are where filters succeed or fail. Ultrasonic welding locks multilayer composites and complex geometries into airtight seams that prevent bypass and keep performance intact across the product lifecycle.
HEPA filters capture 99.97% of particles at 0.3 microns — the benchmark for medical-grade air filtration. We engineer HEPA filter assemblies to your device's exact dimensional and performance specifications, with validation documentation to support regulatory submissions.
Where HEPA isn't enough, ULPA filtration captures 99.999% of particles at 0.12 microns. Used in surgical smoke evacuation and other high-risk applications where the finest particulates and biohazardous contaminants must be reliably captured.
Activated carbon layers adsorb odors, chemical vapors, and gases that particle filtration alone can't address. Used in surgical smoke evacuators and PAPRs where volatile organic compounds and surgical byproducts are part of the contamination profile.
Not every application calls for standard media. We work with hydrophobic materials that repel moisture to protect downstream components, filter paper for precise particulate control, and other specialty media selected for the specific environmental and performance demands of your device.
