Water filtering bottles are a portable way to ensure safe drinking water. Generally, filtration removes a variety of impurities from water in order to produce water that is safe for consumption
UV water filtration neuters biological impurities by rendering them unable to reproduce through UV radiation. However, with exposure to visible light spectrums, reactivation of the impurities can take place over time. UV filtration works best in clear water that will be ingested relatively quickly following the filtration process. UV filtration does not remove the impurities, but simply renders them inert.
