How Do Water Purifiers Work | A Ultimate Guide

If you want to drink clean, healthy water, you know that you cannot afford to drink from your sink every day. But you should consider buying a water purifier to fix this. By purifying your water from home, you will separate your water from dirty contaminants thanks to one or more advanced filters.

There are purifiers in various brands, sizes, and types to consider. Some purifiers are more effective than others based on how they work to purify water.

These purifiers include activated carbon, ion exchange, distillation, and reverse osmosis purifiers. We will give you concise descriptions of each to help you understand which you should consider and which you should avoid.

Activated carbon purifier

This is the most common of residential purifiers. It is affordable, small and simple to use. With this purifier, activated carbon granules made of charcoal are used to block contaminants. This charcoal has a low density rating, allowing it to absorb and trap chemicals found in water. The end product results in crystal clear water.

While this activated carbon purifier is great at removing almost all contaminants, it cannot absorb limescale. Fluoride, sodium and microbes are also not attracted to charcoal, so it will remain in your water.

Another downside to this purifier is that the charcoal will clog up with contaminants, so when it is full, you will have to change the filter from time to time so that you can purify more water.

In summary, activated carbon filters are cheap and do a good job at removing noticeable contaminants, but the water does not get softer, and you have to clean the filter fairly often.

Distillation purifier

This is the most traditional way to purify water; you boil it. Boiling water makes it cleaner, but a distillation purifier works by collecting the steam and extracting it into a separate reservoir when it cools down. This is the water that you would drink.

Using a distillation purifier is a double-edged sword, however. For some contaminants, water will boil at a lower temperature, so they will stay in the first container with water that you wouldn’t use. The caveat is that other contaminants will boil before your water does, so these contaminants do get into the container that you would use.

Distillation purifiers are compact in size and are amazingly affordable, but the problems you might experience include the loss of important minerals and some contaminants will get into your filtered water.

Ion exchange purifier

Ion exchange purifiers are created from a series of zeolite beads. These beads have sodium ions. As hard water goes through the purifier, it will contain calcium and magnesium. The ions from zeolite beads will prefer calcium and magnesium over sodium. In result, they will collect these ions and create sodium of their own.

Unlike the activated carbon purifier, limescale is a is not a problem that you might encounter. Calcium and magnesium are primary parts of limescale.

Because limescale is removed from water, it is softer and better-tasting. With sodium, it will still be present in water, making it taste saltier. That is good news, but there is also bad news. The bad news is that you still will have sodium in your purified water.

Sodium allows the water to taste salty. Expect to taste something different to say the least. You might like the taste, or you might find it too much for your diet.

Ion exchange purifiers make water softer and get rid of unpleasant metals. However, these purifiers take up a lot of space on your counter, and the purified water you get will taste somewhat salty.

Reverse osmosis purifier

Reverse osmosis purifiers usually have multiple filters; often, they have three. These consist of pre-membrane, semipermeable membrane and post membrane filters. Depending on the model you have, some purifiers will even have more than three. 

The semipermeable membrane is the most important filter. This filter is known to block contaminants out according to size and molecular weight. Only contaminants that are microscopic will pass through. This is the most effective of purifiers, and will move about 95 to 99 percent of harmful contaminants inside your water.

These purifiers are the most expensive systems that you can buy, and they do a great job to eliminate all weird smells and tastes from your tap water.

You can guarantee clean water every day, thanks to it’s advanced purifying capabilities. The problem with this purifier though is that you will waste more water than what you would like to. Furthermore, the water will taste more bland, due to how effective it is in removing contaminants.

You likely won’t be used to drinking this kind of water, even when this is considered to be the best filtered water.

So which water purifier is considered the best? It all depends on what you want or need in your drinking water. They all have advantages as well as disadvantages, whether it be from taste, nutrients, cost, and size. In choosing a water purifier, we suggest to follow your gut and go with the type that you will gravitate towards the most.
