Bottled water, barrel water, water purifier, water purifier, which drinking water is more cost-effective?

With the improvement of living standards, people's concern for quality of life, food safety and health has increased significantly. Although it is said that “food is the God of the people”, but as the human body accounts for more than 60% of the material, the quality and safety of water is more concerned.
The variety and price are getting richer. Bottled water, bottled water is very popular, water purification jugs and water purifiers and other water purification devices are also popular.

As consumers, we have only two requirements for water: good quality and cost-effective. So these kinds of water products long-term look down in the end which is more healthy for the human body, and more cost-effective? Today we will do a side-by-side comparison.

01 bottled water, bottled water

The first to say is bottled water and bottled water, it is also our most familiar water products. And because of the bottled water carrying aspect, as well as the reason of the low price of a single product, we want to drink water outside when we will directly buy. But how much do we really know about it?
In terms of water quality alone, bottled water and bottled water are categorized into the following three types: purified water, artificial mineral water and natural water (natural mineral water).

Pure water
When many people see the word purified water, they usually think it is pure water, but this is actually a misunderstanding. The source water of pure water is mostly tap water, with a purity of 99.1% to 99.8%, and in accordance with the hygiene standards for drinking water. Preparation method is generally used electrodialysis, ion exchange, distillation and reverse osmosis, etc., the cost and selling price according to the preparation method and different.
Advantages: no impurities Disadvantages: does not contain any beneficial substances, long-term consumption is likely to cause the lack of certain trace elements in the human body and cause related diseases

Artificial mineral water

People often confuse mineral water with spring water, but the source and treatment of these two types of water are completely different. The so-called mineral water, also called artificial mineral water, is based on pure water with potassium, magnesium, sulfur and other mineral additives. This water tastes better than pure water, however, due to the lack of uniform national quality standards, the mineral water on the market in the minerals added to the more confusing.
Advantages: taste better than pure water, can supplement some of the minerals needed by the human body Disadvantages: no relevant national standards, resulting in uneven products on the market, and a single type of minerals

Natural water / natural mineral water
The source water of natural water or natural mineral water is taken from surface springs or deep underground unpolluted spring water, which is bottled and sold after certain treatment and meeting the relevant national standards.
Advantages: the source water is not polluted, rich in minerals, beneficial to the human body Disadvantages: higher prices

Barrel water vs bottled water
In terms of safety, bottled water has a higher safety factor than bottled water. A few years ago, the media has exposed the “black heart barrel water”, this barrel water is not only not in line with national regulations or recycled without disinfection and direct use of the barrel, and the inside of the filling is also tap water, and as consumers, it is difficult for us to distinguish.

02 Water Purifier pitcher/water filter pitcher
Keywords: convenient, suitable for single-person use, water purification effect is general, cost-effective general
Water jugs, also known as water filters, was invented a few years ago, but the market sales and popularity has not been on and off until the last two years to gradually enter the people's vision, there are also a lot of questions and answers on the Internet about whether it is worthwhile to buy water jugs, it is necessary to briefly introduce the water jugs here.
Water purifier is a household drinking water filtration equipment, compared to the market fire water purifier, water purifier is more suitable for rented accommodation or because of limited economic conditions temporarily unable to install a water purifier family use. Because of its cheap price, and has a certain water purification function and get some consumers love.
The working principle of the water purifier is relatively simple, relying solely on the filter cartridge in the water purifier to filter the tap water. The cartridge of the kettle usually contains a mixture of ion-exchange resin and activated carbon, which can filter out aluminum and heavy metal content in the water, while activated carbon can adsorb chlorine and other organic impurities in the water. After the above filtration, the bottom filtration system filters out the particulate impurities in the water to achieve the filtration effect.
`
Users who have used water purifiers have mixed feelings about their usefulness. Users who like the kettle think that the kettle is very convenient to use, and indeed can achieve the effect of water filtration, coupled with the purchase of a kettle price is generally only a few hundred dollars, if you can't install a water purifier in the home, then buy a kettle is also a very good choice.
But do not like the net water pot users also raised certain questions, first of all, compared to the filter membrane of the water purifier, the net water pot to remove viruses or bacteria effect is very general; Secondly, the filtering effect of impurities in the water, the net water pot can only say that can be done. Previously seen on the Internet about the effect of water purification evaluation, ultra-filtration water purifier can remove 99% of the impurities in the tap water, while the removal effect of the kettle is only about 50%, so the use of the kettle filtered water can be directly drinkable is still in doubt.
The kettle as a kitchen auxiliary water purification appliances is possible, but as a direct drinking water, I do not recommend the use of the kettle. And after comparing several brands of water purifiers, I found that the same business does not recommend drinking water filtered by the well kettle directly, but rather recommended to boil it and drink it. So it's still okay to use it as half an ultrafiltration water purifier.


03 water purifier
Keywords: feature-rich, good filtration effect
Water purifier as the most popular water purification products in recent years, because of its variety, different water purifiers have their own purposes, and therefore focus on it here. Let's first understand the types of water purifiers
Pre-filter
This filter is generally used in areas with poor water quality, due to the tap water in the pipeline transportation process will be mixed with rust, sand and algae and other impurities, the pre-filter is installed near the water meter, you can effectively filter out these large particles in the water. Pre-filter on the water purification function is limited, but it can play a certain role in the protection of water heater and dishwasher and other water appliances, but this water purification equipment can not filter out bacteria and other micro-organisms in the tap water, for the water quality of the region can not be installed.

Ultra-filtration water purifier
Its purification accuracy of 2 ~ 100 nanometers, this water purification equipment can go to the colloidal particles in the water, sediment, ultra-micro particles, heavy metals and bacteria. This water purifier with ultrafiltration water purifier purified water can be used for washing dishes and cooking, but and water softener water is not directly drinkable, if you want to buy ultrafiltration water purifier at home, then it is best to boil before drinking.

Reverse osmosis water purifier
Reverse osmosis water purifier is the highest precision of all water purification equipment, it is also called water purifier, purification accuracy of 0.1 ~ 0.5 nanometers. Reverse osmosis water purifiers can filter out almost all inorganic salts, organic matter, bacteria and viruses in water. The water treated by a reverse osmosis water purifier can be directly consumed, and it is recommended to choose a reverse osmosis water purifier if it is installed at home. However, this type of water purifier has a lower utilization rate of water, and most reverse osmosis water purifiers on the market have a wastewater ratio of about 40%.

Nanofiltration water purifier
The purification accuracy of this type of water purifier is 0.5~2 nanometers, which is between ultrafiltration water purifier and reverse osmosis water purifier. Nanofiltration water purifier can not only filter out all the substances that can be filtered by ultrafiltration water purifier, but also filter out some heavy metal ions and some mineral ions in the water, which is safer to use. Nanofiltration water purifier filtered water is directly drinkable, currently used in primary and secondary schools in most of the water purifier for nanofiltration water purifier.

Is a reverse osmosis water purifier the optimal solution?
As you can see, four kinds of water purification equipment, only nanofiltration water purifier and reverse osmosis water purifier filtration of water is directly drinkable, and reverse osmosis water purifier in recent years in the market will often play similar to “pure water is good for health” and other publicity slogans. However, is pure water really the best for the human body?
In a 2013 RCT, it was found that after 30d of continuous drinking, homocysteine levels decreased in the tap water group, while the pure water group showed the greatest increase, followed by the bottled mineral water group, with no significant difference in the changes in C-reactive protein or arginase between the groups. Elevated homocysteine levels are considered to be an independent risk factor for the development of cardiovascular disease, and C-reactive protein is a strong predictor of coronary artery disease.
The combined findings suggest that long-term consumption of purified water may have a detrimental effect on bone health. The bioavailability of calcium in water is equivalent to or potentially higher than the bioavailability of calcium in milk and dairy products.The results of a 2018 evidence-based evaluation that included 15 studies showed that the majority of studies demonstrated a positive effect of calcium-rich water on both bone biomarkers and densitometric parameters.
The results of a 1999 study in China found that 10.1% of people who consumed tap water (low hardness) had good bone density, and 65.1% of people who consumed deep groundwater had good bone density. There is a direct relationship between drinking water hardness and bone density. Both of these studies show that drinking purified water is negatively correlated with bone health.

At the same time, pure water is acidic and does not contain any minerals, long-term consumption will lead to the body acid-base imbalance and loss of minerals, therefore, for our health, do not drink pure water for a long time.
This, reverse osmosis water purifier can remove the effective substances in the tap water, but also remove the minerals in the water is beneficial to people, long-term drinking instead of the human body is not good, or is recommended to choose the nanofiltration water purifier.

The above is the pure water, water jugs and home water purifier comparison share, you can see that the water purifier in the safety and cost-effective are much higher than the bottled/barrel water and water jugs products, and like Bishuiyuan this central enterprise background enterprises, quality has absolute guarantee.
I hope that everyone will soon drink clean and healthy water !
