Abstract
In various implementations, a filter may include a substrate and manganese oxide coupled to the substrate. The filter may at least remove particles and/or chemicals from a gaseous stream. In some implementations, the filter may be capable of degrading at least one of formaldehyde or ozone present in a gaseous stream.
Claims20
A filter comprising:
- a first substrate comprising pores through which a gaseous stream may at least partially pass, wherein the first substrate comprises:
- a first side;
- and
- an opposing second side;
- wherein the gaseous stream passing at least partially through the first substrate contacts at least a portion of the first side prior to contacting the opposing second side;
- and
- one or more manganese oxides coupled to the second side of the first substrate,
- wherein the one or more manganese oxides comprises at least one powdered manganese oxide;
- wherein the filter is adapted to remove at least a portion of one or more predetermined compounds from the gaseous stream by degrading the one or more predetermined compounds.
6 more elements
A filter system comprising:
- two or more substrates comprising pores through which a gaseous stream may at least partially pass, wherein at least two of the substrates comprise:
- a first substrate;
- and
- a second substrate;
- and
- one or more manganese oxides disposed between the first substrate and the second substrate, wherein the one or more manganese oxides comprises at least one powdered manganese oxide;
- wherein the filter system is adapted to remove one or more predetermined compounds from the gaseous stream by degrading the one or more predetermined compounds.
4 more elements
A method of filtering one or more gaseous streams, the method comprising:
- allowing a gaseous stream with a temperature greater than 0 degrees Fahrenheit and less than approximately 125 degrees Fahrenheit to at least partially pass through a filter;
- wherein the filter comprises:
- one or more substrates comprising pores through which the gaseous stream may at least partially pass;
- wherein at least one of the substrates comprise a first substrate;
- wherein the first substrate comprises a first side and an opposing second side;
- wherein the gaseous stream passing at least partially through the filter contacts at least a portion of the first side prior to contacting the opposing second side;
- and
- one or more manganese oxides coupled to the second side of at least one of the first substrates, wherein the one or more manganese oxides comprises at least one powdered manganese oxide;
- and
- removing at least a portion of one or more predetermined compounds from the gaseous stream by degrading the one or more predetermined compounds as the gaseous stream passes at least partially through the filter.
