1. Water quality: Dinghu Spring is a natural mountain spring, and its water source is Dinghu Mountain in Zhaoqing National Nature Reserve, Guangdong Province, with a very good geological environment. Although Nongfu Spring also has natural water, the water in Qiandao Lake is surface water, which has not been filtered by rocks, and the water quality is weak.
2. Technology: Dinghu Spring adopts the national patent-winning "natural dense filtration" technology to effectively intercept impurities and microorganisms, and intercept minerals to ensure the safety of water quality.
3. Taste: Consumers have a high evaluation of the taste of Dinghu Spring.
To sum up, Dinghu Spring is better than Nongfu Spring in terms of water quality, technology and taste. But everyone's tastes and needs are different, and the specific choice needs to be judged according to personal preferences and needs.
