How to Choose a Water Filter Based on Water Hardness

By: Allen Brown

Fresh water is a necessity of life. No matter how much you trust the tap water in the area where you live, there is always some room for error. This means that one has to be cautious when it comes to consuming water, whether for cooking and drinking or for doing daily chores like washing and cleaning. Many people choose to invest in water filters to ensure that the water is completely purified before they use it. However, deciding on which water filter to go for can be a challenging ordeal if you do not know where to begin. Here are some tips that can help you choose the best water filter for your specific needs, depending on the water hardness where you are located.

Understanding Hard Water

To get the right water filter for your home or wherever you need one, you must first understand what hard water is and why you need to filter it. Hard water is basically flowing water where calcium and magnesium can be found undissolved in high amounts. That hardness can lead to the water feeling unclean, even after using it to clean yourself or to wash items. It leaves an irritating residue that can only be eliminated by using a water softener or a filter. The filter will pick up those small particles of calcium and magnesium and separate them from the natural elements, ensuring that the water you use for cooking or drinking is fresh and safe for use, with no residue.

Reverse Osmosis Filters

Softening hard water is no easy task. That is why there are several different types of water filters out there that can work on clearing the water, using different techniques, including the reverse osmosis method. The BOS review of the Soma water filter explains that the RO filters work in a way that is opposite to the osmosis where the water is pushed from the end that contains a high level of total dissolved solids to the other. This is done by applying pressure in the opposite direction of the water flow. This technique guarantees the separation of solvents and clears the water of dissolved solids along with other forms of bacteria, if any.

Ultrafiltration Devices

This method of filtration is quite similar to reverse osmosis in almost every way. Ultrafiltration, however, differs in the fact that it does not need electricity to operate, unlike the reverse osmosis filters. Another difference is that ultrafiltration uses bigger pores in its water-softening technique, which allows for these types of filters to soften and purify a higher amount of water than other types, such as RO. It is important to realize, however, that ultrafiltration would only be suitable for places where there is not a high level of total dissolved solids, as its large pores would not be efficient in clearing the water.

UV Purifiers

Softening water using ultraviolet purifying techniques can be quite efficient. UV purifiers clear the water of calcium and magnesium along with other bacteria and viruses, using high-intensity UV rays to target the impurities directly and dissolve them where they are. Although UV filters are incredibly effective in separating bacteria and solvents from one another to enable fresh water to flow, they are not that great in areas with high total dissolved solids, as they cannot always target those impurities fully. The water would be softened but not as pure as you would want it for daily use and consumption.

Gravitational Purifiers

A popular new kind of water filter that has taken the filter market by storm is the gravity-based purifier. These filters are very simple to use and can be easily attached to the water tap with minimal hassle and space requirement. However, the perks of their tiny size come with some consequences. Gravitational purifiers offer very basic filtration and purification for water hardness and can only be used in areas where the water is barely impure. It can be used as a precaution when the person already trusts that the tap water is clean but simply wants to take safety to an extra level.

Having clean, fresh water is an essential thing to work for, especially in your home. If you live in an area where you cannot trust the tap water entirely, then you should definitely consider investing in a water filter that will target water hardness. Before making any investment, you should make sure you do some extensive research and understand how impure your water actually is, so you can get the right kind of filter for the best possible results. Remember to clean any filter you get regularly or change it if it is too old, to ensure you always have fresh, clean water.
