I have looked at five important criteria when using each water bottle that can be used: filtering and filtering capacity, materials, taste, easy use and clearing. These are all the factors you need to consider when looking for a water purifier bottle. Wantse you want to buy the one that matches the activity you plan to use. For example, if I was looking for a filtered bottle to take backpacks, I wouldn't choose Britain. Also, I wouldn't invest in Greyl Geopress if I needed a bottle only for tap water.
Filtering
Look for a filtering mechanism that filters harmful contaminants, bacteria and viruses and other unpleasant persons outside the water that cannot be filled. Does the water filter leave particles in the water after filtering? Also, think about how easy the replacement filters are and how easy it is to replace them.
Materials
Most filtered water bottles are made of plastic or stainless steel. If the bottle you see is made of plastic, make sure it is without BPA. Also, make sure it is durable. Would a few drops would endanger the water bottle? If you are hiking and need a light bottle, is the material too heavy?
Taste
It's pretty obvious, but you want a filtered water bottle that leaves you with a taste taste water. Specifically, you do not want residues of mineral odor or chemical flavors, such as chlorine taste.
Ease of use
Putting the bottle together should be easy. The insertion and replacement of the filter should be simple. Also, consider how the water flows from the straw to your mouth. Do you need to tilt it in a certain way to extract most of the water?
Clearing
You want a filtered water bottle that is easy to clean. Check to see if the bottle is safe for a dishwasher. After use, what should you do with the bottle? You can easily store it?
