The system was originally developed for industrial use in printing and photo processing but because of the need for clean water, systems have been adapted for domestic use. Finding the right filter system for cleaner water at home is important if you understand that there are more than 2000 toxic chemicals in our drinking water.

A system is a water filtration system that uses high pressure to force water through a semi-permeable membrane in order to remove minerals, chemicals and toxins. Finding the right system for cleaner water at home will require you to look at the effectiveness of each system.

A major drawback of purifying water through a filter is that while toxins are removed from water, vital minerals (including trace minerals) are also eliminated from the water, leaving it virtually void of any minerals, good or harmful. There are two main types of membranes used in a purification system. If you want clean water at home, you must find the right system with its specific type of membrane. They each have their advantages and disadvantages so it will be up to you to decide which suits you best.

Cellulose triacetate membranes are also known as CTA membranes and are organic and cheaper than the FTC membranes, which are inorganic in nature. CTAs, however, tend to attract bacteria growth resulting in a lower quantity and quality of ‘clean’ water. To counteract this problem, regular disinfection must be performed. The CTA membrane performs best with chlorinated water.

When going about finding the right filter for cleaner water at home, you will find that there are two main types of systems – one with a tank and the other, tankless. Systems that use tanks typically consist of an internal plastic bladder that keeps the purified water before it is dispensed. Systems that are tankless have the ability to dispense their ‘clean water’ directly to taps instead.

If you want clean water at home, you must find the right filter especially if there are a variety of units you can choose from. From systems that are designed with tanks to hold ‘clean’ water to the tankless that can dispense purified water directly to the tap. Units that use tanks are typically use plastic bladder to hold water until it is required for dispensing. These are cheaper than the tankless versions but take up more space.

If you’re looking to finding the right filter for cleaner water at home, you should also be aware of the disadvantages that accompany a water system. Apart from these systems costing a hefty amount and the purified water also expensively produced, the main drawback from using is its removal almost all minerals from water, even trace minerals. As a result, supplements must also be taken to counteract the lack of vital minerals like calcium, magnesium and potassium found in normal drinking water.

If you’ve worked out your budget and are willing to spend the time and money in finding the right filter for cleaner water at home, then installing and maintaining such a system may be a good answer to drinking cleaner water. Bear in mind, however, that there are many other water filters that are cheaper and more apt to serving your domestic needs.

Look for a mid-range filter as most of them can give you quality at a reasonable rate. Taking your time to choose a system if you want clean water at home, you must find the right system that not only suits your budget but can also give you what you want. Remember, an investment may be worth it if you want safe drinking water in the long run.
