Product Overview & Quick Buy
Below are the three alkaline filtration pitchers we reviewed, with direct links to buy on Amazon AU and eBay AU.
Invigorated Water pH Restore
Alkanatur Alkaline Hydrogen Pitcher
What Is Alkaline Filtration?
Alkaline filtration refers to any water treatment system that raises the pH of drinking water above the neutral value of 7. Most home alkaline filters target a pH range of 8.0–9.5. They achieve this through one of three primary mechanisms: mineral-addition media (such as calcium, magnesium, and tourmaline ceramics), electrolysis-based ionizers, or reverse osmosis systems paired with a remineralisation cartridge.
The pitcher-style systems reviewed here use mineral-addition media and multi-stage filter media to simultaneously reduce chlorine, chloramine, heavy metals, and other taste and odour contaminants, while adding beneficial alkaline minerals to boost pH. This makes them a simple, cost-effective entry point for anyone curious about alkaline water without committing to a plumbed-in system.
The global alkaline water filter market was valued at around US $1.2 billion in 2024 and is projected to more than double by 2032, driven by growing health-conscious consumer trends. In Australia specifically, alkaline pitcher sales have surged as people seek to reduce single-use plastic bottle waste while still enjoying mineral-rich drinking water.
It’s important to understand what alkaline filtration does not do. Drinking alkaline water will not change your blood pH — your kidneys and lungs tightly regulate that. The benefits most users experience are real but more modest: better-tasting water, improved daily hydration habits, a pleasant mineral mouthfeel, and in some cases reduced chlorine taste compared to straight tap water. If you need to remove PFAS, lead, or fluoride, you’ll need a system with certified reverse osmosis or specific media — a simple alkaline pitcher is not sufficient for heavy contaminant removal on its own.

Review: Invigorated Water pH Restore Alkaline Water Pitcher
The Invigorated Water pH Restore is one of the most popular alkaline water pitchers on Amazon AU, with over 1,300 reviews and a 4.3-star average. It’s the largest capacity option of the three reviewed here at 3.5 litres (14 cups), making it the obvious choice for families or households with high daily water consumption.
The pitcher uses a seven-stage filtration system that moves water through activated carbon, ion exchange resin, and mineral media to reduce chlorine, chloramine, heavy metals, and unpleasant odours, while simultaneously adding calcium and magnesium to boost pH to the 8.5–9.5 range. One of its standout features is the SmartLight filter change indicator — a built-in LED light that glows green, yellow, or red to tell you exactly when to replace the filter, removing the guesswork.
In real-world use, Australian reviewers consistently praise the noticeably improved taste of tap water and the convenience of the large 3.5L reservoir. Refill frequency is manageable even for a family of four. The slim ergonomic design fits comfortably in most refrigerator doors, and the lid detaches for easy cleaning.
The filter has a rated life of approximately 96 gallons (363 litres) — roughly 2–3 months of typical household use — before replacement is needed. Replacement filters are readily available on Amazon AU. One minor criticism raised in reviews is that the initial few litres through a new filter can produce slightly off-tasting water as the media settles; flushing 2–3 pitchers before regular use resolves this.
Invigorated Water pH Restore Alkaline Pitcher
3.5L capacity • 7-stage filtration • SmartLight indicator • 4.3/5 stars
✓ Pros
- Largest capacity (3.5L) — great for families
- SmartLight LED filter change reminder
- Strong 7-stage filtration system
- Over 1,300 reviews with consistently positive feedback
- Fits standard refrigerator door shelves
- Replacement filters easy to find on Amazon AU
✗ Cons
- First few litres may have off-taste (flush before use)
- Does not provide certified fluoride removal
- Ion exchange resin adds some sodium to water

Review: Alkanatur Alkaline Hydrogen Water Filter Pitcher
The Alkanatur is the premium option in this comparison — and for good reason. With CE, RoHS, and SGS certifications, it is one of the most rigorously tested alkaline pitchers available in Australia. Its most significant differentiator is the use of a patented bioceramic filter that does not employ ion exchange resin, which means it does not add sodium to your water — a point of particular importance for people on low-sodium diets or those with hypertension.
The Alkanatur achieves a pH of up to 9.5 and a negative ORP (oxidation-reduction potential) of around -350mV, which proponents describe as having antioxidant properties. Whether or not you subscribe to ORP health claims, there’s no question the water tastes exceptionally clean and smooth. The filter actively reduces fluoride, chlorine, heavy metals, microplastics, and PFAs while adding magnesium — a mineral many Australians are deficient in.
The filter life is up to 400 litres, which is among the longest of any pitcher in this category and helps offset the higher upfront cost when calculated as a cost-per-litre. The pitcher itself is compact at 1.5 litres — best suited to individuals, couples, or as a complementary desktop unit in an office setting. The BPA-free, BPS-free, and phthalate-free plastic construction matches Alkanatur’s commitment to clean chemistry throughout.
Australian reviewers highlight the measurably improved water quality (verified with pH test kits included in some bundles), the clean Spanish design, and the noticeable improvement in the taste of coffee and tea brewed with Alkanatur-filtered water. The higher price point is the main barrier for budget-conscious shoppers, but the per-litre cost over the filter’s life is competitive.
Alkanatur Alkaline Hydrogen Water Filter Pitcher
1.5L • pH up to 9.5 • Fluoride removal • CE/SGS certified • 4.4/5 stars
✓ Pros
- CE, RoHS, SGS certified — most accredited pitcher reviewed
- No ion exchange resin — does NOT add sodium
- Removes fluoride, microplastics, and PFAs
- High pH (up to 9.5) and antioxidant ORP
- Longest filter life (~400L per cartridge)
- Adds magnesium without adding sodium
✗ Cons
- Most expensive option (~AU $130–$150)
- Smallest capacity (1.5L) — may require frequent refilling
- Replacement filters can be harder to source locally
- No filter life indicator
Review: Ecobud Gentoo Lite Alkaline Water Filter Jug
The Ecobud Gentoo Lite is an Australian brand that has earned a loyal following for delivering reliable alkaline filtration at an accessible price point. It targets a pH range of 8.0–8.5 — slightly more conservative than the other two pitchers reviewed here, but squarely in the range considered ideal for safe, comfortable daily drinking according to most water quality guidelines.
What sets the Ecobud Gentoo Lite apart is its commitment to material safety: it is free from BPA, BPS, and phthalates, which is a higher standard than many competing pitchers that only claim BPA-free status. The filter cartridge uses a combination of activated carbon and mineral media to reduce chlorine, fluoride (partially), heavy metals, bacteria, and other contaminants, while adding alkaline minerals for a comfortable pH and pleasant taste.
The 1.5-litre capacity suits individuals or couples well. The ergonomic handle and detachable lid make filling and cleaning straightforward. Being an Australian brand, Ecobud products are widely available through local retailers, and replacement Gentoo filter cartridges are stocked at Woolworths, Coles online, and major online marketplaces — a significant convenience advantage over international competitors.
The filter life is approximately 150 litres, which is shorter than the Alkanatur but reflects the more aggressive mineral and contaminant removal per litre. Users praise the noticeably smoother taste compared to unfiltered tap water, and the Australian origin story resonates strongly with eco-conscious buyers looking to reduce their reliance on bottled water.

Alkaline Filter Buying Guide: What to Look For
Before purchasing an alkaline filtration system, consider the following factors to ensure you get the right fit for your household’s needs.
Capacity
A household of one or two people will find 1.5L pitchers perfectly adequate — you may fill once or twice per day. Families of three or more should strongly consider the 3.5L Invigorated Water pitcher or similar large-capacity options to avoid constantly waiting for the reservoir to refill.
Target pH
For general health and taste improvement, a pH of 8.0–8.5 (Ecobud Gentoo range) is more than sufficient. If you are specifically targeting antioxidant ORP benefits or want higher alkalinity, look for systems targeting pH 8.5–9.5, like the Invigorated Water or Alkanatur. Avoid routinely consuming water above pH 9.8 without professional guidance.
Contaminant Removal Needs
If your primary concern is taste and mild pH improvement, any of the three pitchers reviewed here will serve you well. If you need verified fluoride removal, the Alkanatur is the only pitcher in this review with certified fluoride reduction. For PFAS, lead, or arsenic removal, a reverse osmosis system with certified media is the recommended solution — alkaline pitchers alone are not sufficient.
Filter Life & Running Costs
Always calculate total cost of ownership. A cheaper pitcher with short-lived filters can cost more over 12 months than a premium unit with longer-lasting cartridges. The Alkanatur’s 400L filter life is the best value per litre of the three reviewed here, even accounting for the higher upfront price.
Certifications
Look for NSF/ANSI, CE, SGS, or WELS certifications relevant to your specific contaminant concerns. Vague “BPA-free” claims with no independent verification should be treated with scepticism. The Alkanatur’s CE and SGS certification package is the most comprehensive of the three pitchers reviewed.
Frequently Asked Questions
Most health authorities and water quality experts recommend drinking water in the pH 8.0–9.0 range for daily consumption. This is comfortable for the body and provides the taste and mineral benefits most users seek. Occasionally drinking water up to pH 9.5 (as the Alkanatur produces) is considered safe for healthy adults, but long-term consumption above pH 9.8 is not recommended without medical guidance.
Most alkaline pitcher filters offer only partial fluoride reduction. Of the three products reviewed here, the Alkanatur is the only one with certified fluoride removal capability. If fluoride reduction is a key priority for you, the Alkanatur is the correct choice among pitcher-style filters, or you should consider a reverse osmosis system with a certified fluoride-removal membrane.
It depends on your consumption and the specific product. The Ecobud Gentoo Lite cartridge lasts approximately 150 litres, the Invigorated Water filter around 363 litres, and the Alkanatur up to 400 litres. For a single person drinking 2–3 litres per day, the Alkanatur filter could last 4–6 months. Always follow the manufacturer’s replacement schedule and use filter life indicators where available to avoid drinking from an exhausted filter.
Alkaline water in the pH 8.0–8.5 range is generally considered safe for children, but infant formula should typically be prepared with water at pH 7–7.5 to avoid interfering with the formula’s chemistry. For older children, the mild alkalinity of a Gentoo Lite or similar system poses no known health risks. If in doubt, consult your paediatrician, particularly for infants and toddlers.
Absolutely. Australian tap water is generally safe but can have a noticeable chlorine taste in some cities. All three pitchers reviewed here use activated carbon to reduce chlorine and chloramine, which significantly improves taste. The added minerals also give a pleasant smoothness that many Australians find preferable to flat tap water. It’s an effective way to stop buying plastic bottles of mineral or alkaline water from supermarkets.
For most common medications, drinking water at pH 8.0–9.0 has no significant interaction. However, if you take medications that rely on stomach acid for activation or absorption, or electrolyte-sensitive drugs, consult your pharmacist before switching to high-alkalinity water. The Alkanatur’s near-9.5 pH is more relevant to this question than the Gentoo’s 8.0–8.5 range.
Alkaline filtered water should be stored in a clean, sealed container (glass or BPA-free plastic). Refrigerated, it retains its quality for 2–3 days before the pH begins to drop as the water absorbs CO₂ from the air. At room temperature, use filtered water within 24 hours. For best results, filter fresh batches regularly rather than storing large quantities.
Final Verdict
All three alkaline filtration pitchers reviewed here are solid performers that will meaningfully improve the taste and quality of your drinking water. The right choice depends on your budget, household size, and specific filtration priorities.
