Water Filters - Why Filter Water

Posted by

Water Filters NZ Why Do We Need Them? Water filters are becoming a necessity even in rural New Zealand as more of our ground water becomes polluted with pesticides and nutrients from farm run-off. 

We are all, more aware of the importance of chemical free drinking water. Whatever the source of your water - from a bore or your roof, or treated City water contaminated with Chlorine, the need for filtration is the same.

We all would benefit from some form of water filtration to improve the quality and taste of our water supply.

If you are on town water then the unpleasant taste will most likely be chlorine.

If you are using tank water and your water is discoloured or smells then your problem is most likely is rotting leaves or pollen from nearby pine trees, as well you can expect bacteria contamination from animal waste, rats, possums, birds... also your water can contain impurities from the zinc coating on roofing iron, aged peeling paint and lead from roof fixings and lead flashings  .

This contamination can be reduced/removed with a well maintained whole house filtration system.

Chlorine is a Health Hazard

In the past adding Chlorine to community water supplies was a relatively simple but crucial step in eradicating water-borne diseases, such as Cholera and Typhoid. Before chlorination, many cities around the world reported death tolls of 1 in 1000 people from Typhoid fever alone.

Chlorine has been used in community based water supplies  for more than 80 years with positive effects. Though in the early 70′s scientists found that chlorine added to water forms Trihalomethanes these chlorination by-products are now known to be harmful.

An American study has shown a 15% to 35% increase in certain cancers for people who use non-filtered chlorinated water. The study found many of the negative effects came from showering in chlorinated water… proving the risks extend past just drinking chlorinated water – the demand for water filters to remove chlorine is very high even more so than filters for tank water or untreated water supplies.

The National Cancer Institute estimates the risk of cancer for people who use chlorinated water is up to 93% higher than those who don’t use chlorinated water. The negative effects from chlorinated water has been hotly debated for years. Though most experts agree... significant risks stem from chlorine and chlorinated by-products in our water supply.

Effective removal of chlorine using carbon block filters is one answer.

Tank Water

Water collected from the roof has long been a favoured source of household water, especially in rural areas, it is often considered the healthy natural option.

the issues are in the collection, transferring and storage of your tank water. Any fecal matter washed of the roof (from bird or possum, rats etc.) has e-coli present, this can cause severe medical conditions, Giardia and Cryptosporidium also enter your water supply this way.

Ceramic water filters or Ultra Violet sterilization are the most effective methods for treating tank water that is carrying bacteria, viruses or e-coli.

VOC’s or Volatile Organic Chemicals…

Volatile Organic Chemicals are synthetic compounds that turn into vapor at relatively low temperatures. Most synthetic chemicals found in water supplies come from farm or orchard run off, such as pesticides and herbicides.

Volatile organic compounds have many harmful effects.

VOCs have been known to cause central nervous system depression (drowsiness, stupor). All VOC’s are a skin irritant as well as irritate the mucous membranes when inhaled.

Granular activated carbon (GAC) filters are typically used to reduce VOC levels in home drinking water
