Comparison of annual cost between bottled water and water purifier;
First, the annual cost of bottled water.
/kloc-The price of 0/8 liter bottled water ranges from 5 to 20 yuan, so let's take 5 yuan as an example. 5 yuan * 162 barrels per year = 8 10 yuan.
Second, the annual cost of water purifier
1. Take the reverse osmosis water purifier as an example (because its filtered water quality is the same as that of barreled purified water). The purchase price ranges from 1500-3000. At present, you can buy a good reverse osmosis water purifier for 2000 yuan. Don't worry about low traffic. Just buy a reliable reverse osmosis water purifier with a flow rate of at least 2 liters/minute.
2. Then, let's look at the consumables in the later stage of the filter. At present, the rated clean water of most brands on the market is above 4000 liters, which means that the core needs to be replaced when the quota of 4000 liters is used up. According to the consumption of 8 liters a day, the cost of core replacement before 1 year is zero.
3. When the initial quota is used up, only the front filter element needs to be replaced in the early stage, and the RO membrane generally needs to be replaced after three to five years of use. The price of the front filter element is generally around 200 to 300 yuan, and it should be replaced once every six months. Then the core replacement cost in the first three years is about 1.200 ~ 1.800 yuan, and the median of three years is about 1.500 yuan.
Types of bottled water and matters needing attention:
First, the type difference.
1. There are many kinds of bottled water on the market, including pure water, mountain spring water, mineral water, mineralized water, activated water and ionized water. Due to different water sources and different production processes, the types and contents of trace elements in different kinds of bottled water are also very different. Some bottled water sources are natural groundwater.
2. For example: mineral water, mountain spring water; Some are city tap water, which is processed into bottled water, such as purified water, distilled water and ionized water.
Second, matters needing attention
1, food will go bad if it is kept for a long time, and water will go bad if it is kept for a long time, so people are usually used to eating fresh food and drinking fresh water, but bottled water should not be drunk when it is fresh.
2. The bottled water sold in the market, whether it is distilled water, reverse osmosis water, mineral water or other pure water, has been filtered and disinfected many times in the production process, but usually ozone is used for the final disinfection before filling, so the bottled water just filled contains high concentration of ozone.
