Smart HEPA Air Purifier

Start Building Tools That Last.

Most modern air purifiers are "black boxes" designed to die when a cloud server shuts down or a proprietary filter becomes unavailable. The SprigStack Smart Air Purifier is the antidote—a product of professional engineering and artisanal care designed for the long haul.

Based on the "Three Rs" creed (Repairable, Replaceable, and Reprogrammable), this project gives you total sovereignty over your indoor air quality.

The Sprig Labs Advantage

• Digital Sovereignty: No corporate clouds, no hidden telemetry, and no forced obsolescence. Your data stays within your four walls.

• Modular by Nature: Built on the SprigStack ecosystem. You can upgrade the "brain" (Sprig-C3/C6) or swap sensors (SPS30/Canopy) without ever throwing away the chassis.

• Professional Engineering: Designed by an Electronics & AI Engineer in Greece, to bridge the gap between "Maker" ingenuity and industrial-grade reliability.

• High-Efficiency "Box" Design: Employs four HEPA filters in a parallel configuration to maximize surface area and airflow while keeping power draw under 15 Watts.

Technical Features

• Precision Chassis: Optimized for 3mm laser-cut materials (wood or acrylic) with 3D-printed structural and decorative elements.

• Customizable Power: Designed for 12V USB-C PD operation, allowing you to power your air filter with modern, efficient chargers.

• Parallel Fan Array: Houses four 120mm PC fans, giving you the freedom to choose the exact balance between high-CFM performance and whisper-quiet operation.

• Smart Integration: Fully compatible with the SPS30 particle sensor and the Canopy environmental module for real-time tracking of VOCs, CO2, and humidity via Home Assistant.

What You Are Getting

This is a Digital Edition launch—a journey from code to casing that you lead yourself.

• Laser-Cutting Files (DXF): Complete blueprints for the chassis.

• 3D-Printing Files (STL): Decorative corners and internal sensor mounts.

• Comprehensive BOM: A "Repair-First" bill of materials including specific fan and sensor recommendations.

• Assembly Instructions: A step-by-step guide to help you cultivate your own smart environment.
