Water filtration is important when it comes to ensuring that you are drinking clean and safe water. There are many different purifiers that you can find but you need to understand the pros and cons of these when selecting a purifier for your home.
RO water filters have a semipermeable membrane that helps in purifying the water. These work due to reverse osmosis. During this process, substances that are dissolved in the water such as fluoride, nitrates, lead, chlorine etc. can be removed from it to provide purified water. If your area has hard water, an RO water purifier would be a good option to select. There are also different types of RO water purifiers due to how you mount the system. There are systems that you can mount underneath your sink (under-counter purifiers), wall mounted systems and table top purifiers. The under-counter purifiers hide the system from view and provide you with more wall and counter space to work with. The taste and smell of the water are improved with this filter. You can easily maintain this system. But one challenge with this system is that it provides a lot of waste water. Also, you will need electricity for the system to operate.
In ultrafiltration, water and other materials that are in the water are separated. There is an ultrafiltration membrane that will trap bacteria, viruses, solid particles etc. This is a little similar to RO purification. But when it comes to an ultrafiltration water purifier, it is able to block larger particles as opposed to smaller particles that are dealt with in a RO water purifier. If your source of water has low chemical contamination, ultrafiltration is a good option. But you need to understand that it will not remove chemicals from the water. The benefit of this system is that no electricity is required and you can use it in low pressure conditions. Unlike in UV purification, ultrafiltration can filter muddy and turbid water. However, you can’t use it with hard water.
An activated carbon water purifier can remove heavy materials and pesticides from the water. It will also improve taste and smell of the water. You can remove chorine quite effectively from water using this system. However, it is not able to remove dissolved salts and therefore remove hardness of water. Sediment filters are quite common and they are used alongside other filtration systems. They can remove turbidity of the water and remove dust, large particles that are present in water. When used with an RO or UV system, it will ensure durability of that system because it prevents sand particles from reaching the system.
A UV water purifier works by killing disease causing microorganisms such as cysts, bacteria, viruses etc. by exposing the water to UV light. If your source of water has low total dissolved solids, a UV filter is a good option. This is if you source water from rivers or lakes. But this will not help you get rid of chemicals such as heavy metals and remove hardness of water. There is low maintenance when it comes to UV water purification and there is a high rate of purification when compared to other systems. It consumes less electricity and will not remove essential minerals from the water. The dead bodies of the germs will however remain in the water. You will not be able to improve taste or smell of the water. The UV system is best served when you use it with another filtration system that can get rid of toxic chemicals.
