AHR Expo focus on indoor air quality (IAQ)

I made the trip to Orlando in February for the 2020 AHR Expo. I traveled to this event with the objective of determining the level of interest in an INDA (Association of the Nonwoven Fabrics Industry)-sponsored Indoor Air Quality coalition. Walking the show allowed me to meet in person with potential IAQ coalition members from …

The main filter mechanisms of fiber material. (B) Filtration efficiency for particles with different diameters. (C) The main filtration effect based on particle size.

There are three primary property considerations of fibers for filtration performance — the choice of fibers, the process of producing the media and the final application.       When it comes to performance, the fundamental fiber properties are those that are designed to optimize volume, air permeability, and the pore size of the material.  …

Manufacture of spiral-wound cartridge filters

A spiral-wound element has significant surface area, resulting in extremely high packing density. The filter is also easy to install and maintain in the system, and it offers a long life due to the durability of the spiral-wound element. The history of desalination dates back to Aristotle and other intellectuals in ancient Greece. In the …

electric car charging

The electromobility (or e-mobility) industry is growing globally. As the auto industry increasingly focuses its attention on electrically powered vehicles, there will be a drastic change in the need for, and type of, filtration in this area. Electric power vs. combustion power The average car has more than 50 filters, which can be categorized in …

By Chris Plotz, Director of Education & Technical Affairs, INDA

My name is Chris Plotz. In February, I took on the role of director of education and technical affairs at INDA, The Association of the Nonwoven Fabrics Industry. This is a fancy of way of saying I’m the technical guy at INDA, and as such the folks at INDA Media, our b2b publishing arm and umbrella for International Filtration News, asked me if I would be interested in writing a regular column. I accepted the offer, and I thought it would be interesting to kick off what has been dubbed the “Tech Talk” column by touching on the issue of Indoor Air Quality. Why?
