How To Choose A Whole House Water Filter System

by Tim Delian on October 21, 2020

How To Choose A Good Whole House Water Filter For The Home

The range of materials and chemicals used in water systems and their adverse effects on our health and overall drinking water quality is key to understanding the need for a whole house filtration system. Chemicals added to water include disinfectants, oxidants, coagulants, flocculants, algicides, antioxidants and chemicals for softening, pH adjustment, fluoridation and scale prevention. Industrial chemicals like PFCs, pharmaceutical residues, heavy metals, and pesticides can all be found in water supplies across Australia and the world. Chlorine, chloramines, fluoride and a range of other chemicals are regularly added to our water supply at local water treatment plants.


Thankfully, safer water requires a relatively small investment in a good whole house water filter. See the information we have gathered below on what you need to know to make informed decisions and improve your water quality.

There are a few questions to ask yourself (and your manufacturer) before getting one.

What does it filter out?

Most whole house filters are designed to filter out sediments with sizes of up to 0.35 micron. Some are made to remove chlorine, iron, and heavy metals. Some systems even include a water softener, UV light purifier and other special gadgets to make sure the water is completely purified.

Does the supplier have independent test results and information from the manufactures or testing laboratories on the effectiveness and life of the filters? 

Is there test results and does it meet NSF standards?

The NSF certifcaiton is a good industry certification but this doesn’t necessarily mean that anything not NSF certified is of poor quality. The cost to get the certifications is extremely high, which will be included in the product price. Some suppliers instead do their own testing in independent labs against NSF/ANSI standards. If they’re well trusted labs, the certification can be meaningful.

What's In Your Water?

Where is the filter made?

A country that has strong quality and material control will ensure that substandard material does not make its way into your filters. We have fount that the USA has the best material traceability and manufacturing and the key AlkaViva filters are made in the USA.

How long is the filter life?

Installing a whole house filtration system more difficult and time-consuming than a countertop filter but will provide filtration across the whole house. Replacement of the cartridge is fairly basic but may require assistance for less mobile home owners.

Ensure you have a quality filter that lasts at least 12 months to reduce spending a significant amount of money too often. It is better to find a good system with 12 months than a cheaper system for 6 months to avoid cost and inconvenience or replacing the filters.

What size is the filter?

A large filter is the best, and provides improved flow rate and contaminant removal. For an average home, the ideal size of a whole house filter should be 4.5″x 20″.

Are you paying for what you really need?

There’s no need to spend on an overkill. That said, never ever ever go for the cheapest when it comes to your health.
