I'll Trade You an Air Purifier for a Job Lead

I'm a mechanical engineer who designed and built a freestanding room air purifier from scratch. Send me a legit job lead, and I'll send you the CAD files. Get me an interview? I'll mail you a parts kit.

Freestanding MERV 13 Air Purifier

Optimized for High Flow and Low Noise

Most consumer air purifiers are too small to be effective, too loud when they are effective, and grossly overpriced. This one is designed with exclusively off-the-shelf or 3D printed parts for ease of filter replacement and drastically lower cost.

Filter Type
MERV 13
14x30x1 Standard Furnace Filters
Air Flow
Up to 350 ft3/min
Up to 650 ft2 at 4 ACH
Noise Level
<35 dB
Effectively silent at half speed
Design Files
.STEP or .STL + Full BOM

The Engineer Behind This

Noah Probst

Noah Probst

I'm a mechanical engineer who believes the best way to show what you can do is to actually do it. I hope this air purifier shows my approach and ability to optimize a solution for a problem from start to finish.

I'm looking for roles where I can bring this same approach: understanding the problem deeply, designing thoughtfully, and building things that actually work.

What I'm looking for: Product design, mechanical engineering, or R&D roles. Open to startups and established companies. Currently, based in Colorado, open to relocation / remote.

Need Something Designed & Built?

The air purifier is simply one of my more practical projects, I’m always working on something. If you have a project that you think I can help with, let’s talk!

Mechanical Engineering

From napkin sketch to production-ready design. I'll take your concept through analysis, prototyping, and design-for-manufacturing so it's ready for the real world.

3D Modeling & CAD

Detailed solid models, assemblies, and technical drawings in OnShape. Whether you need a single part or a full product, I'll deliver files you can actually manufacture from.

3D Printing & Prototyping

Functional prototypes and small-batch production runs in FDM. I handle material selection, print optimization, and post-processing — you get parts that work.
