Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe vera is also a good hand at absorbing formaldehyde. It can absorb 90% formaldehyde contained in 1 m3 air.

Ivy, cycad, chrysanthemum, kumquat, pomegranate, Scutellaria barbata, rose, camellia, Milan, daisy, Chimonanthus praecox, calendula, etc. It can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide.

Cactus and other succulents native to tropical arid areas, the stomata on their succulent stems are closed during the day and opened at night, which absorbs carbon dioxide and produces oxygen at the same time, which increases the concentration of negative ions in indoor air.

Parthenocissus, grapes, morning glory, wisteria, roses and other plants. Planting around the house can make it climb along the wall or along the shelf to form a green arbor, which can effectively reduce sunlight radiation and greatly reduce the indoor temperature.
