Yes definitely, since your bottle is fresh out from our factory, please do hand wash your bottle with soapy water then rinse thoroughly before use. 

For the smell from the bottle, it is because the bottle is brand new and fresh out of the manufacturing warehouse.

We recommend washing it with soap & water when you use it for the first time. Make sure to shake it and let it rest for a while before rinsing it with clean water.

From all of our staff & customers' experience, the smell will slowly fade away after you wash it a few times and eventually dissipate.

Yes, you can place your bottle in the fridge or put ice into the water when you fill it up.

But please do not put your bottle in the freezer as it subjects the bottle to extreme temperature cycles which can weaken the plastic.

Our oversized bottle can take heat actually but we don't recommend it because it is still a plastic material and it might weaken the plastic over time.

We only want this product to remind our customers to stay hydrated at all times as our bodies need at least 3-4L a day.

So we recommend using it for warm water or normal temperature water.
