Innovative Filter Design
Quick Prototype Turn-Around
Medical and Covid-19 Filter Design Services
Are you a design engineer or an entrepreneur in product development with an idea for a medical filtration device or Covid pandemic related air filter, but lack, for now, the technical resources to test your concept, prototype, and/or manufacture pre-production pieces? Could you use some help with the vast and conflicting claims made by the filter media manufacturers?
In the Covid-19 era there will be many opportunities and challenges in medical filter applications.
Hoff Engineering can jump-start your project. Call us. We will optimize your design and help you bring it to reality.
Time to design a device for your medical or anti-viral filter application?
We can help!
For today’s medical devices OEMs innovation must be at the heart of their approach. Hoff Engineering has the technical expertise and resources to design and develop custom filtration devices that are as imaginative as the products they’re part of. Medical device engineers come to us regularly because they can count on innovation, reliability, and value. They know we try to be flexible and easy to work with.
We are a design firm for specialty filters in a wide variety of medical and Covid related custom applications. Our team will consult with you to understand your particular product and objective to then combine creativity and expertise to develop the best solution. We will optimize your design and be your guide thru qualification and certification.
Innovative engineering is essential. We are not copy cats; we are a technology innovator for liquid and air filter design. Our team prides itself on coming up with decisive solutions for unique and hard to solve filtration applications.
For Covid driven and other medical filter applications, we can bring complete in-house engineering services including filter design, prototyping, and pre-production testing for filter projects of all sizes and complexities (concept-to-reality). To make custom designed medical and respiratory filters, our experienced product development team utilizes CAD (Inventor), solid modeling, rapid prototyping, 3D printing, and other state-of-the-art design tools.
1) the ability to really listen; a design team that gets the big picture. The give-and-take between the technical and the business side of a project. The kind of collaboration that speeds time-to-market.
2) budget conscious filter design concepts
3) quick turnaround on prototypes.
4) up-to-date knowledge of the latest developments in the Fibers Technologies, and our long-standing contacts among the pertinent media manufacturing sources.
5) decades of filter production experience. So we always keep manufacturability in mind.
6) numerous US filter patents that enable proprietary solutions
7) an in-house laboratory with the design & test capabilities to support your new medical filter project. These include:
· 3D CAD for step-by-step design & collaborative testing
· Filter media evaluation
o Particulate removal efficiency via two MetOne laser particle counters at 0.5µm and 5 µm
o Precise flow resistance (ΔP) measurements at specific flow rates
o Change in particulate capture efficiency and ΔP vs flow rate over a range of air velocities
o Multi-sample media consistency evaluations of efficiency and ΔP
· 3D-printing in ABS, PETg, TPU, and PLA: Your design or ours!
o Filter housing prototypes
o Design-to-order fixtures for custom filter media shapes & sizes
· Complete material physical properties characterization, including
o Tensile, compression, and yield strength to 1100 lbs-f
o Modulus of elasticity and Durometer hardness
o Cyclic fatigue test response, or test to failure

Qualifying Filter Media
Qualifying the candidate media is the first challenge in the design process of any new medical filter. In the confusing world of medical filter media sourcing, Hoff Engineering can perform the needed independent evaluation of the media manufacturers’ product claims. Procuring and qualifying filter media just got harder this year. In the Covid era, the production facilities and engineering staffs of many meltblown and synthetic manufacturers are booked solid, and it is often difficult to get their attention for new projects, however worthy. As a successful filter manufacturer since 1958, we have decades of successful relationships with the media makers. In the fast-paced medical devices marketplace of today, you can leverage Hoff Engineering’s long-standing contacts and know-how.
These days, the opportunities for medical filters are many. But they are moving at a hellacious pace. It won’t do to be a day late and a dollar short.
Say you have an idea for a medical filter - we’ll help you create it. Fast!
