Frequently Asked Questions (FAQs)

1. Do water bottle filters really work?

While certain filters purify the liquid directly once you pour it into the bottle, others do so as you are drinking it. Either method produces the same result: clean and refreshing water. Thus, to answer the question, filtered water bottles do indeed work.

2. Can you buy filtered water in a bottle?

Most filtered water bottles come in under $100 and give you months of clean, purified water in a very short period of time. Plus, many people find having an easy-to-fill water bottle available at all times helps them drink more water.

3. Do UV water bottles work?

After placing water into the bottle, the UV light can combat the bacteria and leave you with water that is purified and healthy for you to drink. However, it can also be unsafe to use and may not work. In essence, UV light cannot be used if the water is murky, muddy, or has floating debris in it.

4. What does a sport Berkey filter?

The exclusive filter element of this Sport Bottle is composed of our exclusive proprietary "adsorbing" media that promotes IONIC "adsorption" of pollutants, such as cadmium, chromium, copper, lead, aluminum, mercury, and other dangerous heavy metals.
