Home Water Filters NZ

There are many home water filters NZ consumers can choose from. Activated carbon, Reverse osmosis, UV, and Activated alumina are just a few of the options. Each of these systems performs different functions. Understanding each type is essential in choosing the right filter for your needs.

Activated alumina

Activated alumina home water filters are an effective way to filter the water in your home, and most of them use household pressure to produce treated water. However, it is important to know that activated alumina filters must be disposed of properly or they will contaminate your water supply. Additionally, activated alumina may not be completely effective at removing coliform bacteria, which is one of the most common types of bacteria. This is why it is important to have your water tested to ensure the effectiveness of your filter.

When purchasing an activated alumina home water filter, be sure to choose one with NSF certification. These certifications are given to water filters that pass strict safety standards. A home water filter certified by NSF will not leach aluminum into the water, and will not have aluminum or other impurities that can cause health problems.

Activated carbon

Activated carbon is an essential part of many home water filters, and it can help protect your family from contaminants. Carbon filters have a large surface area and can absorb large amounts of toxins and chemicals. A single gram of carbon has about 500 square meters of surface area, equivalent to about one tenth of a football field. The surface area is a major factor in the effectiveness of carbon filters.

Activated carbon filters are one of the most common types of water filters. They can remove chlorine, odors, and other contaminants. However, activated carbon filters cannot remove harmful organic compounds or significant levels of metals or pathogens.

Reverse osmosis

Reverse osmosis home water filter systems can be an efficient way to clean your water. They can filter as much as 50 gallons of water each day. However, they are not instantaneous. They take some time to refill, so you should consider buying one with a higher capacity.

Reverse osmosis home water filter systems can remove many types of contaminants. These systems typically come with a carbon filter as an extra layer of filtration. This carbon layer helps to filter out contaminants that reverse osmosis cannot remove. These contaminants include disinfection byproducts and volatile organic compounds. These substances can damage the development of children and cause birth defects. They can also impact growth and impair a child’s brain function.


UV NZ home water filters are one of the best ways to remove harmful impurities from water. While most UV systems will last for several years, a few need to be replaced. This is due to a reduced UV lamp life after about 9,000 hours. This is because the mercury content in the UV lamp degrades over time. It is best to replace your UV lamp before this point to ensure continued effectiveness. Most UV systems have simple installation processes, including slipping the UV lamp into a sleeve and attaching it to your water line.

UV water filters do not change the taste or odor of water. Unlike other methods, UV water filters don’t need to be cleaned frequently. In addition, you only need to replace the lamp every couple of months or so. Another benefit to UV water filters is that they are inexpensive, which means they are an excellent option for a whole-house filtration system.

It has a unique, click-button design that allows you to quickly switch between unfiltered and filtered water. The system is fully recyclable and features a satisfaction guarantee.
