			  The ornamental design for a portable room  air  purifier  with horizontal grid one-piece cover and shroud, as shown and described.
 
			  
			  
			  
			  
			 
		 
	 
 
	
FIG. 1 is a top plan view of a portable room air purifier with horizontal
grid one piece cover and shroud showing my new design;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a front view thereof; and,
FIG. 4 is a bottom plan view thereof.
The mesh grill is partially shown in FIG. 2 for ease of illustration and is
understood to extend 360° around the circumference of the cover.
The rear and sides of the portable room air purifier are substantially the
same as the front except for the control means at the bottom front of the
housing.
