Snow is not usually pure H2O because it can capture impurities from the atmosphere as it falls. These impurities may include dust, pollutants, and even microorganisms. While snow is mostly water, it's rarely chemically pure due to these factors. If you require truly pure water, it's best to rely on distilled water for that purpose.
