In today's world, air quality is a growing concern, with pollution levels rising and more people becoming aware of the importance of breathing clean air. Enter Sappe, a portable air purifier with a unique UV purification feature designed to help people breathe cleaner, fresher air wherever they go. In this case study, we will explore the background, challenges, and solutions of developing Sappe, as well as the results and feedback from users.


Sappe was born out of a need for a practical, portable, and effective air purification solution. Air pollution is a major problem in urban areas, causing respiratory issues, allergies, and other health problems for millions of people worldwide. Traditional air purifiers can be bulky, expensive, and limited to indoor use. Recognizing the need for an affordable and portable solution, our team set out to create a compact air purifier that could be used anywhere, anytime, with the added benefit of UV purification to destroy viruses.


The Challenge

The development of Sappe presented several challenges, including:

  • Size and portability: Creating a compact and lightweight device without compromising its air purification capabilities.
  • Power efficiency: Designing a battery-powered device with a long-lasting battery life for continuous use.
  • Noise reduction: Ensuring the device operates quietly so as not to disturb users in various environments.
  • UV purification integration: Incorporating UV technology to destroy viruses while maintaining a user-friendly design.
  • Affordability: Offering a competitively priced product without sacrificing quality or performance.
  • Problem

    Air pollution has become a critical issue worldwide, particularly in urban environments. The increasing number of vehicles, industrial emissions, and other pollutants contribute to poor air quality, which can lead to various health problems such as respiratory issues and allergies. Furthermore, airborne viruses can cause diseases like the flu, the common cold, and more severe illnesses like COVID-19. Traditional air purifiers, while effective indoors, are not portable or practical for use in public spaces or on the move, leaving individuals exposed to harmful pollutants and viruses when they step outside their homes or offices.



    Our team of engineers and designers collaborated to develop an innovative solution to these challenges, ultimately creating the Sappe portable UV air purifier. Key features include:

  • HEPA filtration: High-efficiency particulate air (HEPA) filtration technology, which effectively removes 99.97% of airborne particles as small as 0.3 microns.
  • UV purification: Integrated UV-C light technology that destroys viruses, providing an extra layer of protection against airborne pathogens.
  • Compact design: A sleek, pocket-sized design that allows users to carry it with them wherever they go.
  • Long battery life: A rechargeable battery that provides up to 12 hours of continuous use on a single charge.
  • Whisper-quiet operation: An advanced motor and noise reduction technology ensure minimal noise during operation.
  • Cost-effective: A competitive price point that makes clean air accessible to a broader audience.
  • Developing process

    The development of Sappe involved several stages, including:

  • Conceptualization: Identifying the need for a portable air purifier with UV purification and defining the product's key features.
  • Design and prototyping: Creating multiple design iterations and prototypes to test size, shape, and functionality, including the integration of UV technology.
  • Testing and refinement: Rigorous performance and safety testing to ensure Sappe meets industry standards and user expectations.
  • Market research: Gathering feedback from potential users and adjusting the design accordingly.
  • Production: Manufacturing the final product and preparing for launch.
  • Results

    Sappe has received positive feedback from users, with many praising its portability, effectiveness, and affordability, as well as its unique UV purification feature. Customers have reported improved breathing, reduced allergy symptoms, and an overall sense of wellbeing when using the device in various environments, such as public transportation, offices, and outdoor spaces.

    In addition to improving individual air quality, Sappe has made a positive impact on the environment by raising awareness about the importance of clean air and encouraging users to take a proactive approach to their respiratory health.
