Abstract
The present disclosure provides for filters, filter systems, methods of using filter systems, and methods of detecting targeting airborne particles, and the like. The present disclosure provides for filters that can capture one or more types of targeted airborne particulates, where the presence of each of the targeted airborne particulates can then be detected. The filters can be used in industrial gas systems, laboratory gas systems, HVAC systems, portable filter systems, respirator systems, and other residential, commercial, or industrial air circulation or air control systems.
Claims14
A filter, comprising:
- a plurality of filter fibers coated with a hydrogel material on the surface of the filter fibers, wherein the hydrogel material on the filter fibers has a hygroscopic characteristic, wherein the hydrogel material is selected from the group consisting of:
- polyacrylamide copolymer and hydroxyethylmethacrylate, wherein the hydrogel material coated on the filter fibers is about 5 to 10 micrometers thick.
A method of detecting targeted airborne particulates, comprising:
- providing a filter, wherein the filter, comprises a plurality of filter fibers coated with a hydrogel material on the surface of the filter fibers, wherein the hydrogel material on the filter fibers has a hygroscopic characteristic;
- trapping targeted airborne particulates in the filter;
- exposing the filter fibers to a first colorimetric composition, wherein the first colorimetric composition reacts with the targeted airborne particulates to produce a first detectable indication;
- and
- measuring the first detectable indication to confirm the presence of the targeted airborne particulates.
