8-Stage KDF Filtration Mechanism
The 8-Stage KDF Water Filter Cartridge is engineered to process municipal tap water through a systematic sequence of physical barriers and chemical reactions. Designed with a universal fit, it is compatible with most standard gravity-fed water coolers and dispensers.
Constructed entirely from BPA-free materials, this multi-stage system performs dual functions: aggressive contaminant reduction and passive remineralization. By passing water through specialized layers of media, the cartridge actively reduces heavy metals, neutralizes chlorine, and elevates the water's pH to an alkaline state.
Understanding KDF Technology
Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc formulation utilized primarily in the second stage of this filter block. It functions via oxidation-reduction (redox) reactions, actively exchanging electrons with contaminants present in the water supply.
This electron exchange process safely converts harmful chlorine gas into benign, water-soluble chloride ions. It also binds to heavy metals—such as lead, mercury, cadmium, and arsenic—along with hydrogen sulfide, effectively removing them from the active water supply before the water enters the lower collection tank. Additionally, KDF media significantly extends the operational lifespan and efficiency of the activated carbon layers beneath it.
Core Filtration Stages
As water drips through the cartridge housing, it is subjected to eight distinct stages of treatment to ensure structural purity, chemical reduction, and remineralization.
- Primary Filter Felt Pads: Acts as a preliminary silt pad, physically removing suspended rust, sediment, and particulate matter from the tap water.
- KDF Media: Utilizes redox reactions to heavily reduce chlorine, organic matter, and heavy metal contamination.
- Activated Carbon: Adsorbs volatile organic compounds (VOCs), actively reduces fluoride compounds, and eliminates the residual odors and tastes associated with municipal chemical treatments.
- Mineralised Balls: Begins the remineralization process by releasing beneficial, earth-derived trace elements into the water, including iron, zinc, lithium, magnesium, potassium, and iodine.
- Mineral Coralite Balls: Provides a slow release of primary minerals (predominantly calcium) to further enhance the mineral profile and stabilize the water's alkaline pH level.
- Refined Activated Carbon: An additional, finer granular layer of activated carbon that polishes the water and assists in the alkalinization process.
- Advanced Mineralised Balls: A finer-grade version of the media used in Stage 4 to ensure consistent mineral density in the final output.
- Ceramic Plate: Serves as the final micro-porous physical barrier to prevent internal filtration media and remaining physical impurities from escaping into the lower water reservoir.
Multi-Pack Configurations
To support long-term maintenance cycles for residential and commercial setups, the 8-Stage KDF replacement cartridges are available in several multi-pack configurations. Because each cartridge is rated for 6 months of use, ordering a multi-pack secures a continuous supply of filtered water.
| Configuration | Total Price (AUD) | Cost Per Cartridge |
|---|---|---|
| 1 x Filter Cartridge (6-Month Supply) | $38.00 | $38.00 |
| 2 x Filter Cartridge (12-Month Supply) | $64.00 | $32.00 |
| 3 x Filter Cartridge (18-Month Supply) | $84.00 | $28.00 |
| 4 x Filter Cartridge (24-Month Supply) | $108.00 | $27.00 |
Maintenance & Service Life
To maintain peak effectiveness and consistently convert tap water into highly filtered alkaline mineral water, the filter cartridge must be replaced every 6 months. Actual cartridge lifespan may vary depending on the turbidity of your local water source and daily consumption rates. Cartridges can be sourced directly from our water filters collection.
Frequently Asked Questions
What specific trace elements are added to the water?
Through the utilization of natural Mineralised and Coralite balls (Stages 4, 5, and 7), the filter passively infuses the water with Calcium, Magnesium, Zinc, Iodine, Lithium, Potassium, and Iron, establishing an alkaline pH balance.
Is this filter compatible with my existing water cooler?
Yes, the cartridge is designed with a universal fit to accommodate most standard gravity-fed bottled water coolers that utilize a multi-stage drop-in filtration reservoir.
Does this filter remove fluoride?
Yes. The integrated activated carbon layers work in conjunction with the other filtration media to actively reduce fluoride compounds found in standard municipal water supplies.
Shipping and Delivery Policy
Ace Water Shop can ship to virtually any address in mainland Australia, including Tasmania. Unfortunately, outlying islands off the mainland may incur extra charges.
Note that there are restrictions on some products. Our free shipping offer delivers to most areas around Australia, but some regional areas may incur extra charges from the transport company for delivery to your door.

Surcharge Chart for Heavy or Bulky Items
Additional shipping charges apply to some items of unusual size or weight. If a surcharge applies to your order, it will be indicated on the product page or during checkout. If a freight quote is necessary, we'll contact you with the additional surcharge as quoted by our courier, if applicable.
Freight is calculated per order, based on the destination and items being shipped. We provide free shipping for metro areas, but outside these areas, we request a quote upon receiving an order. Freight costs depend on the cubic size and/or weight of the product, the destination, and the level of service required.
If an item cannot be delivered to the provided address or if you place an order without acknowledging the freight quote, we will contact you via email with the extra shipping fee after the order is paid. You will need to pay the extra fee for the order to be delivered. Orders without shipment service or those declined due to extra shipping fees will be canceled and refunded automatically with email notification.
Change of Mind Request Procedure
We offer a 30-day no-questions-asked return policy for our ace water filtration systems, minus return shipping costs. We also offer an unlimited 2-year warranty on our compressors and a 12-month warranty on all parts of our Ace Water Coolers & Purifiers.
- Consult with us about any change of mind refund request before returning the product.
- Contact us via email at acewatercoolers@gmail.com or chat with us on the website, providing pictures or video that shows the condition of the received product and explaining why you wish to return it.
- Returns due to change of mind must be arranged by the customer.
- If a change of mind return is accepted, we will refund the item price minus return postage and a restocking fee of 10% of the item price and the shipping fee, or just the restocking fee if no return address was provided. For items returned to sender before receipt, the refund will include a restocking fee and the shipping fee, provided after the item is received back at our facility.
Waterworks Water Coolers Warranty
We offer a 36-month comprehensive warranty on bottle top & POU coolers and the IC8 chiller from the date of purchase. Most transactions may not be covered by the Australian Consumer Law (ACL), but all goods are warranted to the level provided by Waterworks Australia. Returns, for warranty purposes or otherwise, must be pre-approved and at our expense.
Under the ACL, consumers are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. The guarantees, rights, and remedies under the ACL vary significantly by factors such as industry standards and the nature of the product. Waterworks Australia adopts this approach for its warranty policies.
