An air cleaner is provided. The air cleaner includes a main body, a case coupled to an outer side of the main body and comprising a suction port for sucking air into the main body, a filter unit disposed inside the main body, a dust sensor for sensing dust concentration, a first flow path provided so that air sucked through the suction port is flown to the side of the dust sensor, and a second flow path provided so that air filtered through the filter unit is flown to the side of the dust sensor, and the dust sensor may sense first dust concentration of air provided through the first flow path and sense second dust concentration of air provided through the second flow path.

The invention relates to a filter module for trapping overspray from booth air laden with overspray from coating facilities, particularly from painting facilities, having a module housing, in which a filter structure (88) is accommodated and which has a module inlet (74) and a module outlet (76), wherein the filter module (40) is designed in such a manner that it is swapped for an empty filter module (40) once a limit loading of overspray is reached. The filter module (40) comprises a recyclable reusable structure (112) of one or more reusable components that can be thermally regenerated and therefore the filter module (40) can at least partially be thermally regenerated. The invention also relates to a trap having one or more filter modules of this kind, a coating facility for coating objects (14) and to a method for operating a coating facility.

A replaceable air filter element has a multilayer filter medium panel configured for mounting on a reusable exoskeleton support frame. The exoskeleton support frame is installable on a flow face of the filter medium panel and is provided with U-shaped locking members configured to detachably engage with and mount the filter medium panel. The exoskeleton support frame is configured to be reused such that only the filter medium panel is replaced, thereby reducing the environmental waste and making for a “green” eco-friendly air filter element.

A powered air purifying respirator includes an inlet air filter; a flow generator configured to cause air from an ambient environment to flow through the inlet air filter and elevate pressure of the air to above ambient conditions; a mask in fluid communication with the flow generator and configured to fit tightly against a user's face or neck for delivery of the air to the user at the elevated pressure; and a one-way outlet valve configured to allow air exhaled by the user to be vented to the ambient environment. An outlet filter may be included to filter the air flowing through the one-way valve, and the outlet filter may be retrofit. The outlet filter may be preferred when filtration of both inlet and outlet air is desirable.
