Infrared filters， sometimes called IR filters or heat-absorbing filters， are designed to allow IR mid-infrared wavelengths while block visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating.
There are also filters which are used in solid state (CCD or CMOS) video cameras to allow IR due to the high sensitivity of many camera sensors to near-infrared light. These filters typically have a blue hue to them as they also sometimes block some of the light from the shorter visible light and UV wavelengths.
This IR filter can block all visible light under 950nm， therefore let you experience some different shooting.

In which ways the infrared filter will be used?

Archaeology，Military，Police，Medical science，and detective work. Infrared filter allow normally invisible stains and modified items visible.
Plant vegetation & Landscape photography. It looks dramatically different when photographed in Infrared.
Photographic special effects. Infrared filters give the still and video photographer expressive and unusual effects.

In what suitable light source should I use the infrared filters?

680nm for indoor and weak Shadows use.
720nm for indoor and weak light use， for ordinary DC/DV/DSLR cameras
760nm for cloudy outdoor at nightfall and brightness indoor.
850nm for indoor and weak cloudy outdoor light.
950nm for outdoor and strong light，such as summer time.
1000nm for low latitudes and strong reflective light ，such as on the beach by noon time.

Kindly Note:

1. You'd better remove the IR-blocking filters in front of CCD or CMOS sensor when using IR filters
2. Setting the white balance
3. If you don't want to do any transformation on your device， you can do some post processing after shooting to achieve the IR effect.
