Common Types Of Water Filters And Their Features
Posted on: 10/12/2017, by : Roger Meadows


If you have decided to purchase and install a water filter in your home, you have made the right choice. However, now, you are probably faced with a tough task of choosing the right filter. Since there are a plethora of models and types on the market, you can easily find yourself confused as to which one to buy. To help you out with this task, we will cover the three most commonly used types of water filters today.

The reverse-osmosis types

22bvkjcjhThese can be installed as whole-house filters or under-counter ones. Reverse-osmosis filters were initially designed to clean salt water only. These days, they are commonly found in households, where they function by forcing water through a membrane, thus blocking the contaminants and allowing the water molecules to pass through. Sediments such as copper, mercury, and iron are effectively blocked, as well as all kinds of bacteria and other contaminants. This type of filter is also quite easy to maintain and clean.

The main drawback of a reverse-osmosis filter system is that it can waste a lot of water as it needs a higher ratio of unfiltered – filtered water, so as to push the molecules through the membrane. Usually, this ratio is 4:1, which means a lot of water is simply being wasted.

The activated carbon types

These are also known as activated charcoal filters. These types function by binding the water contaminants to the surface. This surface is quite massive as it has millions of tiny nooks and crannies. Where the “binding” process occurs. The main advantages of activated carbon filters are that they waste no water, are inexpensive, readily available, and held in small cartridges.

The most notable drawbacks of these filters include very frequent replacements. Also, if maintained improperly, they can easily become moldy, Shower filters that utilize the active carbon method can easily break down after being exposed to a lot of hot water, if not properly maintained. They can also become a breeding ground for mold, as well. If you want to avoid these problems, make sure to regularly maintain the filters and replace them when needed.

The ceramic types

These types of filters are made from fossilized remains of sea life. They are exceptionally effective when it comes to filtering out large sediments, alongside all kinds of viruses and bacteria, Ceramic water filters are commonly used in outdoor water filter systems, where the main objective is to filter out pathogens, instead of chemicals. Keep in mind that these types of filters do not filter out chlorine. For that, you will have to combine it with another type of filter.

Other systems

In addition to the previously mentioned types, you can also come across a number of other types of filters, which you can find at Easy Water Solutions.

Ionizing water filters

These filters are mainly used to separate the alkaline from acid and provide both in equal measure. These filters are mostly used in health clinics and hospitals.33nbxmbkj

Ultraviolet water filters

These function by bombarding the water with ultraviolet rays, which effectively eliminate all pathogens. Ultraviolet filters are exceptional when it comes to disinfecting water. However, they cannot filter out chemicals or sediments.

KDF filters

KDF filters feature a brass alloy that creates a strong galvanic action, which, in turn, breaks down chlorine. These filters are commonly used in shower heads, as the zinc and copper in the alloy are more effective at high temperatures.
