Why choose a 1 liter insulated bottle?

Among the different models of reusable water bottles, insulated bottles hold a special place. Although it is not always visible at first glance, they are designed with a double wall. These two surfaces are then separated by an air gap. It is this assembly that allows the liquids to be kept at a given temperature despite the external conditions. A 1 liter insulated bottle keeps drinks hot or cold for a variable number of hours depending on its composition.

Insulated water bottles contribute to a zero waste lifestyle where simplicity allows for long-term savings. No more shopping for single-use plastic bottles, just open the tap. A small gesture that has a big impact on the environment, but also on health.

Tap water is subject to many preconceived ideas, yet it is regularly checked by health organizations. On the other hand, filtering devices with charcoal sticks can be added directly to the caps of insulated containers.

Plastic bottles, on the other hand, transfer nanoparticles into liquids, which then end up in the body. Adding to this the high price of water packs (30 euro cents per liter on average compared to 0.30 cents for tap water), the 1 liter reusable bottle is an economical and healthy alternative.

Isothermal flasks promote good daily hydration and offer the possibility of quenching your thirst with different hot or cold drinks according to the tastes and desires of the moment: black coffee, green tea, fruit flavored water... No more breaks at the vending machine for drinks expensive and bland!

The materials

Plastic insulated bottles are often appreciated for their lightness, just like aluminum ones. However, they both have an interior coating which may contain harmful particles. Sensitive to heat or corrosion, these water bottles can then alter the taste of drinks.

Glass insulated bottles are free from any toxicity. These are healthy and ecological gourds which however present risks of breakage in the event of shocks. Stainless steel bottles are strong and durable. Stainless steel does not transfer odors or toxic substances into drinks. In addition, the 1 liter water bottles ensure great autonomy by keeping liquids hot for 12 hours and cold for up to 24 hours.

So when making your choice, be sure to favor a brand that offers spare parts, so that you can replace the seal without having to change the bottle.

How is a reusable stainless steel bottle maintained?

The 1 liter stainless steel insulated bottles are not dishwasher safe. They can be cleaned very easily with water and dishwashing liquid, possibly with a non-abrasive sponge for the exterior surfaces and a brush for the interior walls.

After washing, simply leave it to dry in the open air, on a stable support, upside down without a cap.

From time to time it is advisable to carry out a deep cleaning, especially if you have consumed drinks which can leave deposits, such as fruit juices with pulp or smoothies.
