AlkaWay Whole House – Optimal Safe Water Filter

$1,949.00 inc. GST

The Whole House – Optimal Safe Water System delivers optimal safe water for a whole medium to a large house with 2 or more bathrooms on town or tank water at an affordable price. This three filter system has superior sub-micron filter capacity and removes most heavy metals.

The system contains three filters:

  • 1 micron Nominal Sediment Filter
  • 20-micron Radial Granular Activated Carbon (GAC) Filter
  • Ultra-D Sub-micron Filter

Each filter is enclosed in 20-inch filter commercial strength housing.

For more information, please contact Leon, our whole of house water filter specialist on 1800 268 469.

Optimal Safe Water System Benefits

  • Removes pathogens
  • Removes heavy metals
  • Removes taste and odour
  • Chemical and organics removal or reduction
  • Suitable for the food and beverage industry for high purity water
  • Other high purity applications
  • Finer particle retention and filtration capacity (2 to 3-micron pore size comparable to a 0.02-micron size for virus and bacteria removal)
  • Higher loading capacity (up to 25 times greater)
  • Wider pH operating window (4 – 9pH)
  • Very low-pressure drop (approximately 2 psi)
  • Easy to install
  • Easy to maintain

NOTE: Doesn’t remove Fluoride. Fluoride can be mostly removed when used in conjunction with the UltraStream, the world’s most advanced water filter unit. The UltraStream purifies, alkalises, ionises and infuses the water with molecular hydrogen. Ideally, it would be added to the kitchen for drinking and cooking water.

All whole house systems use the same basic filter media: a combination of sediment filter, carbon filter and antibacterial ultraviolet. Filter capacity is maximised because we don’t like to change filters too often, and yet we need large filters because satisfactory performance is only achieved with a flow rate that doesn’t ‘die’ when you are in the shower and someone turns on a tap and the sink (More information on our Whole of House range).

Review our Installation manual.

* Reduces chlorine, endocrine inhibitors. Ibuprofen trace hydrocarbons, and Volatile Organic Compounds. Arsenic, Cadmium, Chromium, Lead, Silver, Iron, Mercury and Selenium.
** While whole-house filters may struggle to successfully and reliably remove Fluoride, because the water needs time to interact with the media in order to remove or reduce the fluoride in the water, the flow rate will be slow.  An effective way to address Fluoride is to combine these systems with the UltraStream drinking water filter.
*** Most customers add an UltraStream drinking water systems to remove bad taste, colour or odour issues.
**** On average each filter should last up to 12 months. This will depend on the water usage over that time and the condition of your water source. So, it may need replacing sooner than 12 months.


Our key ‘Consider this’ factors: 

1. Water source: Creek water, spring water, rainwater.. all have very different characteristics.

(a) Creek water is a prime source of bacteria mainly from faecal matter, either animal or human upstream. It can also be high in sediment especially after solid rain upstream or in the area. We take into consideration your need to be able to remove and clean a sediment filter without stress.

(b) Spring water is thought to be wonderful water, but today it’s not necessarily so. In vast areas of Australia, spring water can be highly alkaline. While not a bad thing, (it has been shown to be very healthy) it often has serious effects on your hot water service, your shower rose, and your kettle, and we look at alternatives to prevent the accretion of calcium in this form. In other areas such as Western Australia, iron can be a major component of spring water. Around our area we often find spring water to be quite acidic, because of the accumulative effect of composting layers of subtropical foliage.

(c) Tank water labours under another myth that water from the sky is clean. It is not, because it falls through a layer of quite mixed pollution onto a roof that is a catchall for airborne pollution (in its myriad forms), sweeping the accumulated pollution into a tank that usually accommodates at least one form of dead mammal. A recent serious problem for tank owners has been the discovery that bats (flying foxes etc) faeces carry many very serious diseases. Flying overhead, the bat faeces drop onto roofs and are washed into our drinking water tanks. As we know, in some areas thousands of bats pass overhead twice a night.

2. Tanks are also commonly thought to hold pH-neutral water. This is seldom the case. A concrete water tank will leach calcium into your water for up to 20 years, whereas modern plastic or fibreglass tanks seriously acidify your water.

3.  pH: This brings us to the whole question of pH for a whole of house filter. We do offer the alkaline pH system, but generally, only recommend this for areas that have highly acidic water. In general, we try to make sure that the only water with high alkalinity is your drinking water. This is most easily achieved with an at-tap system like the UltraStream, simply because alkalising all of your home water has no real benefit except (as already stated) your water is so acidic that it needs alkalising.

4. Bacteria and Viruses are a much bigger problem with water tanks than with city/municipal water supply, simply because it does not have chlorine in it. Some farmers have even taken the step of installing a chlorine generator to keep their water tank clean, but we feel that it’s more economical and more healthy to kill bacteria using ultraviolet light rather than a known carcinogen. Tank water users also regularly report that their skin is far better cared for and supple with no chlorine in the system. A good UV system, regularly checked, will achieve extreme kill rates for all manner of bacteria.

5. Media: As we mentioned, we will select the right media for your particular installation and budget. Generally, we offer two forms of sediment filter and two forms of carbon. We don’t want to bore you with all the tech specs, so we suggest giving us a call or email.

6. Quality: We only source NSF-approved media and replacement cartridges. Most pre-made units on the market use substandard filter media. We have learned the ‘tricks of the trade’ over the years and have made the decision that happy clients are better than high profits.

Replacement Filters
