This is the 3rd time refilling my sirena air twister water air purifier and i am still loving it! Definitely do not recommend using the scent booster beads in it like some sirena air purifier videos show! They clog up the mechanics of the purifier! PS imagine what thats doing to your clothes. Just saying 😁 #sirenaairpurifier #airpurifier #sirenatwister #waterairpurifier #goodsmellinghome #smellgoodfeelgood #smellgood #homefragrance #essentialoils
