The invention discloses novel indoor purifying equipment for an energy saving room. The novel indoor purifying equipment comprises a box, a fresh air inlet, a first air return inlet and an air outletare formed in the box, the box is internally provided with a low-efficiency filtering net, a first surface cooler, a heater, a humidifier, a second surface cooler, a draught fan, a medium-efficiency filter and a high-efficiency filter in sequence, the low-efficiency filtering net is close to the fresh air inlet and the first air return inlet, and the high-efficiency filter is close to the air outlet. By means of the novel indoor purifying equipment for the energy saving room, external fresh air and air in the energy saving room can be mixed, the mixed air is subject to first-time filtering, heating and humidification, middle-grade filtering and high-grade filtering, efficient and thorough purification is applied to the indoor air actively, the requirements for energy saving and emission reduction are met, the external fresh air can be introduced in good time, and the indoor air quality is greatly improved.
