HYGGE Pure

What it does

HYGGE Pure is a home air purifier that targets a hidden health risk—airborne microplastics. Using advanced filtration, it captures plastic particles as small as tens of nanometres in size, protecting users from inhaling harmful pollutants.

Your inspiration

This project responds to the rising concern of airborne micro and nano plastics (MNPs) in domestic environments. These ultrafine particles, released from the breakdown of everyday items such as furniture, carpets, and synthetic fabrics, can remain suspended in the air and are small enough to bypass standard HEPA filters, posing significant health risks over time. The idea came from identifying a gap in current air purifiers: none targeted airborne microplastics or addressed exposure during filter disposal. I explored electrospun nanofibres as a solution after researching advanced filtration technologies.

How it works

The air purifier is designed to remove microscopic plastic particles from the air. It uses a quiet fan to pull in air, which passes through a multi-layer filter. The key layer is made of electrospun nanofibers—tiny threads formed using electricity—that create a dense mesh capable of trapping ultrafine plastic particles. These particles are too small to be seen and are often missed by regular filters. The design uses sustainably sourced materials such as bamboo plywood blending clean air technology with eco-conscious living.

Design process

The design process began with research into indoor air quality and the overlooked threat of airborne microplastics. I identified a clear gap in existing purifiers, which typically target dust and allergens but not ultrafine plastic particles. Early concepts focused on combining high-efficiency filtration with sustainable design. After exploring various materials, I developed a layered system featuring an electrospun nanofibre filter capable of capturing particles down to tens of nanometres in diameter. To validate the concept, I tested the filter in domestic environments using an existing air purifier. Contaminants collected on the electrospun layer were examined with a scanning electron microscope (SEM), and EDX analysis successfully confirmed the presence of microplastics. In parallel, I explored form and function—developing scale models, CAD iterations, and refining the internal layout for improved airflow. A key goal was to ensure the design complemented modern interiors while remaining efficient and user-friendly. The final prototype introduced a built-in sealing mechanism: a filter bag that seals shut before disposal. I iterated this system using zip-seal and twist-lock approaches, improving both safety and usability.

How it is different

HYGGE Pure is a compact air purifier designed to capture airborne microplastics in the home. It draws in air using a low-noise fan and passes it through a multi-layer filter system. At the core is an electrospun nanofibre layer—an ultra-fine mesh made by electrically drawing biodegradable polymers into microscopic threads. This layer can trap plastic particles as small as tens of nanometres, which are too small for most standard filters to catch. To protect users when changing the filter, the system includes a built-in mechanism that seals the used filter in a bag before disposal, preventing particles from escaping back into the air. The outer body uses sustainably sourced materials like bamboo plywood and anodised aluminium to complement modern interiors while reducing plastic use.

Future plans

I want this concept to raise awareness of invisible pollutants and help set a new standard for healthier, more sustainable homes. Next, I plan to further develop a key element of the design to expand its reach and make advanced air filtration more accessible to a wider audience.
