Low-Cost Air Purifier: Engineering for Mass Market Accessibility

An air purifier priced for the mass market, not the premium shelf
Our client, a USA-based company, wanted an affordable air purifier that could compete with expensive market alternatives while keeping essential functionality intact.
CADLETE Designs handled the complete product journey as a turnkey engagement, from industrial design through PCB integration to supply chain development, with cost built into every decision rather than added at the end.
What made this project hard
Tooling cost reduction
A large product size required eliminating undercuts entirely to keep the injection mold cost-effective.
Simplicity without looking cheap
Balancing affordability with practical engineering, so the reduced complexity did not read as a compromise.
Ventilation design
Optimizing airflow efficiency across intake and outlet vents within a simplified form.
Electronics on a budget
Fitting PCB systems, a display interface, and components within tight budget constraints.
From concept to a working, cost-optimized prototype
Four stages, one team, no handoffs between them.
Industrial Design
Multiple concept options explored for intentional manufacturing simplicity.
Zero-Undercut Engineering
Mechanical design ensured full compatibility with injection molding.
PCB & Display Integration
Complete PCB design integrated with the display interface.
Functional Prototype
FDM 3D printed prototype built with real, integrated electronics.
Industrial design with cost built in from the start
Multiple concept directions were explored with intentional simplicity for manufacturing, so the form itself supported the target price point rather than fighting it.


Zero undercuts, engineered from day one
Mechanical engineering ensured zero undercuts for injection molding compatibility on a large enclosure, the single biggest lever for keeping tooling cost down.
Ventilation was optimized for airflow efficiency across intake and outlet vents within that simplified geometry.
PCB and electronics integrated on budget
Complete PCB design and system integration covered the display interface, with user experience work focused specifically on filter replacement accessibility.


A functional prototype with real HEPA filtration
A functional FDM 3D printed prototype was built with integrated real electronics and a working HEPA-based filtration setup, with supply chain support set up for the HEPA filter and other components.
What shipped
"A cost-optimized, fully functional air purifier, ready for manufacturing with complete vendor and supply chain support established."
