Abstract

A nasal filter using nanofiltration was designed to filter out pollen particles from the air, placed in a 3D printable customized housing. First, the design requirements for the filter were specified by determining the size of allergen, allergy causing particles, and studying the nasal airflow and nasal airway resistance. Electrospinning parameters were set to produce a nanofilter which adheres to the design requirements for the nanofilter. Second, the design requirements for the housing were specified. The material of the housing had to be 3D printable, biocompatible, flexible, and transparent. With the requirements, elastic resin from Formlabs was chosen as material. Furthermore, five prototypes for the housing were developed. The housing should not hinder breathing through the nose and therefore the prototype with the highest emerging airflow was chosen. Finally, the value of a reusable housing was estimated to be €10.04. The filter, which needs to be changed after 140 minutes, is estimated to cost €0.14. The nasal filter costs in total €12.00, with the initial purchase of the housing and assuming the user goes outside each day for four hours and thus needs two new filters each day.
