A nasal air filtration device for filtering air inhaled by a user is disclosed. The nasal air filtration device includes a pair of nostril tubes including a filter at one end and an ionic plate at other end. Each of the nostril tubes includes a cup having a plurality of openings. The nasal air filtration device includes a base tube coupled to the nostril tubes. The base tube includes an exhaust channel. The base tube includes a first housing having a battery and a second housing having a fan. In order to filter the air inhaled by a user, the nostril tubes are placed inside nostrils of the user. When the user inhales, the fan is operated to draw the air into the base tube, and the air is made to pass through the filter and the ionic plate provided at the nostril tubes into the nostrils via the openings. When the user exhales, the air is released into the atmosphere through the exhaust channel via the nostril tubes.

A powered air purifying respirator (PAPR) device comprises an enclosure extending along a longitudinal axis between a first end of the enclosure and a second end of the enclosure. The enclosure defines an air inlet in fluid communication with environmental air. A filter module is disposed in the enclosure in fluid communication with the air inlet for filtering the environmental air to produce clean air. A blower system is disposed in the enclosure in fluid communication with the filter module for pressurizing the clean air. The enclosure includes an upper housing for receiving the filter module. A plate extends between the first end and the second end defining an air outlet in fluid communication with the filter module and the blower system. The air inlet is disposed adjacent the second end and the air outlet is disposed adjacent the first end.
