The WS 2700 has the same features as the WS 1500 including the remote control. The WS 2700 is the WS 1500 with an extra ION Generator Cell. The ION Generator boosts the output of the standard WS 1500 to a powerful 2700 square foot output of  BiPolar Ion Clusters. Great for spaces larger than 1500 square feet or when a lot of people or pets are in a room.
