Frequently Asked Questions

Our bottles are not dishwasher safe. Putting our bottles in the dishwasher can cause damage to the vacuum seal and to the outside of the bottle.

For best results, hand wash your bottle with a non-abrasive dish soap. Our bottle brush is a great tool for making sure your bottle is as clean as can be. After washing your bottle, let your bottle air dry upside down with the cap off. We recommend cleaning your bottle after every use.

Mira bottles are made of high-quality, 18/8 food-grade stainless steel. We use a copper coating in between two stainless steel layers, making our bottles very durable and resilient to rust. All Mira bottles are BPA-free, providing a healthier and more Eco-friendly alternative to plastic water bottles. With proper care, your bottle should last for years. 

Our MiraGuard technology keeps liquids inside the bottle cold for 24 hours. Placing bottles in the refrigerator/freezer will not change the temperature of the contents inside of the bottle. We do not recommend putting bottles in the freezer, as it may cause the vacuum seal to break.

Your bottle should not make a rattling sound. If it does, it means that the small metal disk used during the vacuum-insulation process has become dislodged.
