The Stay Diffuser has three run times: 6 hours, 12 hours, and 18 hours. The 6-hour setting will run continuously; the 12-hour setting will run for two minutes on, two minutes off; and the 18-hour setting will run for 2 minutes on, 4 minutes off, either until the water in the reservoir is low or the time period has ended. As part of an automatic safety feature, our diffusers turn off before the water reservoir is completely empty.

The outside of the diffuser is made of high-quality matte metal. The inside reservoir is made from BPA-free plastic. Because the diffuser is ultrasonic and runs on vibrations instead of heat, there is no interaction between the water, plastic, and essential oils.

Yes. The Stay Diffuser has 4 light settings: on, dim, candlelight, and off. You can adjust the light settings by clicking the light button at the back of the diffuser. You can also press and hold the light button to turn off all the lights.

All Stay Diffusers come with a lifetime warranty. If your diffuser has any mechanical or manufacturing defects, we would be happy to assist you. Please reach out to us at hello@vitruvi.com with your proof of purchase, information on the issue you’re experiencing, and the serial number (located on the bottom of your diffuser). We would be happy to support you and ensure you have a perfectly working product. Please note that our lifetime device warranty does not cover personal damages

Our pets are as unique as us. The first thing we suggest doing is checking with your vet—your animal may be more sensitive than others, so your vet will know best. Stronger scents such as Lemon, Grapefruit, Peppermint, and Boost, should be used sparingly. If you would still like to diffuse one of these scents, I would suggest limiting the number of drops to approximately 1-5 drops. Frankincense, Lavender, and Cedarwood are great options to diffuse around animals. We also suggest turning your diffuser off when your animals are home alone, just in case they do become agitated by the scent. For more information, visit our page here.

The best thing to do before using essential oils is to chat with your doctor. In a diffuser, we recommend using small amounts of essential oils when pregnant (about 5 drops). When it comes to newborns, we recommend waiting 3 months before using essential oils. But your doctor will know best, as we all react differently. Always opt for essential oils that are 100% pure, vegan, cruelty-free, and free from synthetic fragrance. These are the products we recommend starting with once you’ve spoken to your doctor: Lavender, Bergamot, Grapefruit, Lemon, Frankincense, Cedarwood, Boost, Sleep.

There may be a few reasons why your diffuser isn’t misting properly. Here are some ways to troubleshoot the issue. First, give your diffuser a deep clean. As a part of a built-in feature to protect our diffusers, the unit won’t run if the ultrasonic plates are clogged with essential oils. Watch our video above for instructions on how to clean your diffuser. Next, make sure the water is filled to just below the line inside the reservoir. If there is too little or too much water in the reservoir, the diffuser won’t turn on.

Ensure that the water is filled to just below the fill line to get a full time cycle. In addition, environmental factors—such as the humidity in your space and the type of water used—may affect the run times by approximately 15%. If you notice a large discrepancy in run time, please reach out to us at hello@vitruvi.com.

Make sure you’re using the original power cord that came with your Stay Diffuser. If you misplaced your power cord, don’t worry—we sell replacement parts here. We also suggest plugging your diffuser into a different outlet to ensure it’s not an issue with your power source. Next, ensure that the water is filled to just below the fill line. If the internal sensor notices that there is too little water in the reservoir, the diffuser will not turn on. Also, make sure that the Stay Diffuser lid is sitting completely flush on the base.
