FAQs

Is the Hydro Flask Micro Hydro BPA-free?

Yes, all Hydro Flask products are made with non-toxic, BPA-free materials.

Can I put carbonated drinks in this bottle?

Yes, however, use caution when opening as pressure can build up and cause spray.

Does it fit in a standard cup holder?

Yes, its slim 400 ml profile is specifically designed to fit most standard vehicle cup holders.

Can I put the bottle in the freezer?

No, freezing can damage the vacuum insulation. Use ice cubes to chill your drink instead.

Is the exterior finish durable?

The bottle is crafted from pro-grade stainless steel, which is highly resistant to daily wear and tear.

How long will the paint last?

The exterior is designed to be durable, and because the unit is dishwasher safe, the finish is built to resist fading and chipping.

Troubleshooting

Bottle feels hot to the touch on the outside

This indicates a failure in the vacuum seal. Please check the product warranty or replace the unit.

Lid is leaking during transport

Ensure the cap is screwed on straight and tight. Inspect the silicone gasket under the lid for debris or damage.

Stains or lingering odors inside

Perform a deep clean with a mixture of baking soda and warm water, or run a cycle through the dishwasher.

  • Dishwasher safe for easy maintenance

Setup, Compatibility & Care

To begin using your Micro Hydro, ensure the cap is tightened firmly until you feel the seal engage. For optimal thermal performance, pre-heat the interior with hot water (or pre-chill with cold water) for a few minutes before adding your beverage. When cleaning, place the bottle and cap on the top rack of your dishwasher. While the bottle is robust, avoid using harsh abrasive scrubbers on the exterior to preserve the colour finish. Do not use the bottle in a microwave or freezer, as this can damage the vacuum seal and the physical structure of the product.
