The various applications of multilevel inverters are 1. Motor Drives 2.Active Filters 3.Power conditioning
IIR filters have nonlinear phase characteristic which means the output of such a filter is (most likely) a deformed version of the input without the filtered frequency. On the other hand IIR filters might become unstable. So IIR filters are used, when the user is not particularly interested in the output in time-domain but only in frequency-domain, e.g. in audio applications such as speakers...
Low pass filters are used for various purposes in different areas.

Applications of active and passive filters?They are used for signal conditioningThey can be used to bypass power supply.They can also be used in speaker crossover designs.

Compressed air filters, which are also known as in-line filters, serve the purpose of filtering contaminants, such as dust, oil and moisture, from air after it has been compressed. They are usually used in industrial applications.
It fits 284 different applications. Proline filters are made by Purolator for Pep Boys, and they use the same five-digit numbers on all their filters--Purolator makes a LOT of private-label filters. If you would like to see what this fits, go to http://www.pureoil.com, click on "Vehicle Applications" then "Where Used Guide." Feed in part number PL24651 and stand back. This is the weirdest filter--it fits GM, Ford and Chrysler applications.

IIR filters are recursive and FIR filters are non-recursive. Also FIR filters are linear phase and IIR filters are not; several applications are sensitive to non-linear phase (communications, medical, etc). In implementation, IIR filters require fewer taps (smaller order) and thusly are easier to implement and have fewer zeros. Also FIR filters are always stable, while IIR filters can often become unstable in implementation. The previous answer is correct about delays.
