Whole House Water Filters
Whole house water filters are designed to provide quality water in the entire house and not just at the tap in the kitchen.Having said that , if you get your water from a well or borehole it is imperative that you have a water analysis done to determine what is in the incoming water feed so that the company supplying the filters can take into account all water issues.
Water is a universal solvent and all types of chemicals and nutrients are found in it. Most are beneficial in small quantities but some are a health risk and this may increase depending on the filtration system used. e.g if the water is relatively high in Sodium and a water softener is added then the water softener adds more sodium to the water to remove the hardness. In so doing the Sodium levels can increase dramatically which is a heart risk for people suffering from Hypertension or heart diseases.
Whole house water filters with municipal treated water is much easier as most municipalities treat the water to an acceptable level and the elements that have to be removed are far less problematic than groundwater.

like other systems are designed based on what problem has to be resolved, how fast the water flows and at what pressure. These important factors determine the size and nature of the filters and many options are available to suit most problems.
There are no generic water filters as each media type does a specific job and there are very few filters that can solve every water related problem. But there are some filters that form the basis of most systems.
In municipally treated water the major concerns are removing the chlorine, colour and sediments that may have been introduced in the piping systems and killing any bacteria or water borne diseases that may have got through.
A whole house water filter system to resolve these issues would comprise between 2-4 elements namely a sediment removal water filter cartridge to larger suspended particles such as rust, dirt, mud , leaves etc. The second water filter may be a activated carbon filter with an additive such as nono-silver or KDF-55 to remove chlorine and heavy metals , general herbicides and pesticides. The Third element may be a UV steriliser if the water is prone to e-coli infection or water borne bacteria.

To keep costs down on a whole house water filter system it is important that the water filters be installed on the incoming water supply after it splits off to the garden otherwise the water volume required and therefore the size of the filters and inherent cost of the media in the filter can increase dramatically.
Whole House Water Filter System for Borehole Water
Designing a whole house water filter system for a borehole can be substantially more complicated as the water quality may be seasonal and change in the dry and rainy months. These water quality changes could include hardness, degraded colour , bacteria infestation, chemical seepage from nearby industry and many more so a water analysis is always the starting point and preferably more than 1 test taken over the 2 seasons
Again the factors that will affect the cost are the amount of water required per hour , the current flow rate, the pressure of the incoming water, the type of pipe currently being used and the output water quality desired.
A typical whole house water filter system used on a borehole would comprise a pump at the borehole, chemical dosing of chlorine for bacteria control , a holding tank , feed pump to apply pressure to the outgoing sediment and activated carbon filter and UV steriliser if required . The output water is then pumped into the feed line in the house
Whole House Water Filter System for Borehole
Whole house water filter systems for a home start at around R5 200 ex Vat and installation and those for a borehole around R12 500 depending on what is required.
