The effect of indoor air filtration on contaminant distribution and occupant exposure
Poor indoor air quality, driven by the presence of airborne contaminants, can have a significant effect on human health particularly given that we typically spend upwards of 80% of our time indoors. A potential solution for improving indoor air quality is to filter the air inside buildings, thereby …

Next generation of electrospun textiles for chemical and biological protection and air filtration
(cont.) only in the presence of water, which serves as a medium promoting the nucleophilic action of the amidoximes in the fibers. Bactericidal fiber mats were produced from electrospinning of blends containing a biocide chlorhexidine (CHX). A small amount of high molecular weight poly(ethylene …

Supramolecular Nanofibers - Preparation, Structure-Property Relations, and Applications
… textiles as protective suits, and especially in air filtration as filter media. Generally, nanofibers are prepared by top-down approaches. However, these processes feature several disadvantages. As consequence cost-effective alternative strategies are required. One strategy to this problem is the …

Dynamic Botanical Filtration System for Indoor Air Purification
<p>A dynamic botanical air filtration (DBAF) system was developed, tested and modeled for indoor air purification. The DBAF system consisted of an activated-carbon/hydroculture-based root bed for potted-plant, a fan for driving air through the root bed for purification, and an irrigation system for …
