Unlike other cleaning agents, Ecosys refills are 100% soluble and contain a concentrated liquid that works like magic when dissolved with water. Plus, it is so simple to use! You just need to use your favourite spray bottle and dissolve the capsule with regular tap water. Shake until it completely dissolves and it is ready to use after 2 minutes. Spray a fine mist on the corners of your room/space and witness the magic of Ecosys Air Freshener 100% soluble refills! We adhere to plastic free packaging and therefore use no plastic in packing our products.
