Whenever you go shopping for a water filter systems Australia for drinking purposes, there are many considerations you have to make. Choosing quality products from reputed manufacturers with great after-sales services is a must, but even more important is the type of water filtration device you choose. Since there are many types available in the market, it may be a good idea to get informed about them, such as knowing the advantages and drawbacks of each type of filtration.
There also exist many other types of filtration other than the ones listed below. For example, you can order fridge filters online to install them in your fridge for easy water filtration. Nevertheless, they aren’t as common, so it may be a better idea to focus on the others, which are as follows:
- Gravity Based Purifiers – These are often considered as the most basic type of water purifier out there. They simply use a difference in pressure to move water from one chamber to another, through a filter designed to filter out some germs and bacteria, as well as unnecessary salts and sediments. They are extremely cost effective and have large capacity, but they aren’t as effective as more modern types of filtration devices.
- RO Purifiers – RO or Reverse Osmosis Purifiers are suitable to remove heavy metals like lead, mercury, cadmium and harmful sediments like arsenic and fertilizer compound from water. Their great purification abilities make them great for both domestic and commercial use, but they do have high costs associated with them, particularly due to maintenance and their dependence on electric power. They also cannot filter out bacteria and other microorganisms.
- UV Purifiers – Using ultraviolet purification techniques, this type of purifier excels at removing bacteria, germs and viruses that may be present in water. This features also makes them useful for purifying water for purposes other than drinking, which explains their use in some pool filters out there. UV purifiers will also not affect salt concentration in any way, which means that water won’t taste acidic. Sadly, these also require electricity to operate, and they cannot remove heavy metal particles.
- UF Purifiers – UF here stands for Ultrafiltration, and it describes their use of an ultrafiltration membrane to get rid of harmful salts and minerals while keeping useful ones intact. They can also filter out bacteria, although not as effectively as UV purifiers. Their lower costs and ability to operate without electricity make them a suitable alternative to RO purifiers, although the latter type is recommended for water with extremely high heavy metal particle concentration due to their higher effectiveness.
- Multi-Stage Purifiers – These are purifiers which use a combination of two more types of the purifiers listed above for a more effective purification process. The most popular (and arguably the most effective) type of multi-stage purifier is the one that combines an RO purifier and an UV purifier. Together, they work in tandem to free water from heavy metal contaminants as well as living matter like bacteria and other microorganism.
