Best Water Filters in New Zealand

The 8 Best Water Filters in NZ New Zealand Tested

The water we use is extremely important since this is what will end up in our cooking, showering, and drinking. Thus, to help you keep healthy, we’ve outlined the best water filters in  NZ New Zealand!

As you know, New Zealand homes take their water supply from the streams. Though clean, these have a likely chance of becoming contaminated with bacteria, protozoa, chemicals or sediments.

In addition, they can lead to a person getting disease and having poor health. Even if you are just taking a bath with dirty or chlorinated water, it can make your skin dry, irritated, peeled.

But there’s a solution to all that, which is to use the best water filters in NZ. First, we will differentiate the main types of filters, though, with the pros and cons of each one — this is so that you will know what to pick on our list!

Three Kinds of Water Filter Solutions in NZ

Whether you are searching for a benchtop water filter in NZ, or one to take with you on your camping trip, or just for saving space, these are the different kinds of water filters that you can use:

1)   Faucet

This water filter type is very easy to install & you won’t even need to open the cabinet below. It is simply attached to the spout of your faucet and locked in place, ready to use.

It filters quite effectively but not as well as full-system filters. Also it is cheaper in cost, but you will need to replace it every few months depending on how much water you are using.

2)   Cartridge

Cartridges are a type of water filter shaped like cylinders that you install under the kitchen sink. Once installed, it goes to work to remove the microbes, particulates, and chemicals from your water supply.

Though it is convenient and space-efficient, it can only supply water for up to several months to a year or more. And similar to the faucet water filter, it has to be replaced frequently.

3)   Full System

Full system water filters are suitable for permanent use at home. Each is designed with a cleaning process that separates bacteria, protozoa, sediments, lead, asbestos, and awful odours and tastes.

You will have access to clean and wholesome water for anything you need.

“Our drinking water is so much better (our city is notorious for its nasty water), and the filters are very reasonably priced. Not only that, but the prices haven’t noticeably changed over the last 6 years, a shocking contrast to Kenmore.
