What is off-grid?

According to Wikipedia's explanation, I made a summary, which is also my own understanding: off-grid is a feature of buildings and a way of life. It refers to designing a building in an independent way so that it can achieve self-sufficiency of people and buildings without relying on one or more public facilities. The public facilities here include the public power grid, water supply system, natural gas system and sewer system, etc.

Why do some people choose to go off-grid?

There are many reasons why people choose to go off-grid. They want to take a RV trip; they are tired of life in the big city and want to experience life close to nature; perhaps some people are worried about urban riots and choose to stay away from the city. Of course, in addition to these active off-grid ones, there are also passive off-grid ones, such as the paralysis of public facilities and water pollution due to hurricanes and fires. Before receiving government relief, they will have to be self-sufficient.

How to protect off-grid life?

Off-grid living is all about independence—but one thing you can’t compromise on is safe drinking water. When you’re far from city utilities, running to town to buy bottled water isn’t always practical, and natural water sources like rainwater, rivers, and lakes often become your primary option. The challenge is that “clear” doesn’t mean “safe”: these sources may contain viruses, bacteria, sediment, organic contaminants, and even heavy metals.That’s why, for anyone planning an off-grid lifestyle, the key question becomes: How do you reliably turn unknown outdoor water into safe drinking water anytime, anywhere? The answer is a water purifier. The common filter elements on the market include PP cotton filter element, activated carbon filter element, ultrafiltration filter element and reverse osmosis filter element (RO filter element).

Among them, the main material of the PP cotton filter element is polypropylene, and the filtration accuracy is between 0.5um and 20um. It is generally used as a pre-filter to filter large impurities in the water. There are many kinds of activated carbon filter elements. The coconut shell activated carbon filter element commonly used in water purifiers is a kind of granular activated carbon. Its main raw materials are coconut shells, almond shells, walnut shells and other shells or anthracite coal. Activated carbon has a good adsorption effect and can effectively remove residual chlorine, odor, color, and organic matter in water, and is often used in secondary filtration. The filtration accuracy of the ultrafiltration filter element is between 0.01-0.001um, which can remove some bacteria and viruses in the water, but cannot filter heavy metal elements,It is often used to filter tap water and cannot be used when the water quality is unknown.The last is the reverse osmosis filter element, its filtration accuracy is between 0.001-0.0001um, and it can filter substances larger than water molecules, including heavy metal elements. At first, reverse osmosis technology was used in the space capsule to solve the water problem of astronauts. In the small airtight space of the space capsule, every drop of water is very precious. The sweat, urine produced by astronauts, and the water used for bathing must be recycled, which is why the water treated by reverse osmosis was also called space water. Of course, because the pore size of the reverse osmosis filter element is very small, the reverse osmosis technology squeezes water molecules from the high concentration area to the low concentration area. Due to the violation of the normal water flow direction, the side with high concentration needs to be pressurized during use, so it needs electricity to maintain, but the water filtered by it will be cleaner than the water filtered by other filter elements mentioned above. It can be seen from the above that different filter elements are used in different scenarios. PP filter elements and activated carbon filter elements are often used as pre-filters; if you only use tap water, you can use a water purifier with an ultrafiltration filter element; In order to drink outdoor water safely, it is very necessary to be equipped with an electric-driven RO filter water purifier. Here, you are very welcome to choose ITEHIL’s RO Water Filtration System.

In addition, I would like to remind everyone that due to the strong filtration capacity of the RO filter, the minerals/electrolytes contained in the water will almost be removed, which requires you to supplement additionally to supplement what the body needs.

Therefore, I recommend ITEHIL’s remineralization filter, which adds back key minerals the body needs—such as calcium, potassium, sodium, magnesium, and zinc—and helps balance the water’s pH to 8.5. A slightly alkaline pH (around 8.5) can also make the water taste smoother and may help some people feel more comfortable if they occasionally experience acid reflux.
