By using two to three wax melts, you can expect about 8-12 hours of scent however that time can vary based on your wax warmer. Some wax warmers can get way too hot, way too fast. This will make the scent a lot stronger as its melting but will significantly reduce your burn time. If you use a wax burner that doesn’t get too hot, your level of fragrance will be less intense. However, you will be able to use the melts for longer. It’s super important to monitor and understand how the temperature on your wax warmer works to maintain your melts’ throw. You may even want to set a timer while you use your melts to save some scent for another time. Fun fact: Wax candles only hold a certain amount of fragrance and differs depending on the type of wax used. Through vigorous testing we chose the wax we feel is the best and made sure we added the highest amount of fragrance oil allowed.
