Abstract
An air purifying bed tent is disclosed, having a tent made from a semipermeable material suspended over a raised platform, thereby creating an enclosure for a user to be inside. An air purifying device is connected to the top of the tent, letting purified air into the enclosure and creating a local clean air zone for users. The positive pressure difference building up in the enclosure from the constantly added clean air forces clean air out through a plurality of openings, primarily through creases in the semipermeable material around the raised platform. Should the skirting be completely sealed, the semipermeable material will let out the pure air to a higher degree, ensuring a stable and easy touse operation.
