Water filters are the most-used products in the market. These are the filters that help you in removing or reducing the impurities from contaminated water. Some of the impurities that these filters remove are lead, nickel, iron, mercury, and copper. The filters are said to purify more than these like virus and bacteria. They also restore the vitamins and minerals of water.

Though they do not assure to remove 100% of these bacteria and virus from the water, they reduce their level in the water. They make the water almost safe for consumption and not completely.

It is not always easy to carry water purifiers when you are on a trip because they are bulky. It is, therefore, recommended to carry a filter instead so that you have better accessibility to potent drinking water.

If you have to chose between a water purifier and a water filter, first determine what purpose you wish to use it for. If it is for the whole family at home, use the purifier. Filters are only for emergency purposes and purifiers are for consumption at home.

It really depends on your choice and your water requirements. Buy it from the market or online, always read the features and the functionalities of both the products and decide accordingly. Checking for the price range is also important since a filter could be on the cheaper side than a purifier.

Does Water Filtration Remove The Important Minerals Required For The Body?

It is true that filtration can remove minerals from the water, but they would not have added a significant number to the body’s overall requirements. Most of our nutrients are absorbed from food and not water that we drink.

You never know when a tornado hits or the area is inundated and you may have to just look for an alternative shelter, which is mostly likely an emergency camp.

Most often than not, these camps just have the bare minimum necessities, like a small shelter and running taps or borewells.

There is no guarantee that the water you are using here is absolutely fit for drinking or cooking. A collapsible water filter bottle could save your day in such a situation. If each of the family members has one of his own, access to clean drinking water would not be a problem at all.

However, ensure that the filtration capacity of the filter is high because you do not know how long will you have to stay in a camp before you headed back home.
