How Alkaline Water Filters Work
Alkaline water filters work in two main phases: contaminant removal followed by remineralisation. Understanding this process helps you appreciate exactly what you’re getting in your glass.
In the first phase, water passes through layers of activated carbon, ion-exchange resin, and sometimes sediment pre-filters. This removes common tap water nasties including chlorine, chloramine, heavy metals (such as lead and copper), sediment, and other organic contaminants that cause unpleasant taste and odour.
In the second phase, the filtered water passes through a mineral media — typically a blend of calcite, ceramic balls, tourmaline, or magnesium — which slowly dissolves trace minerals into the water and raises its pH. The result is water with a pH typically between 8 and 9.5, enriched with calcium, magnesium, and potassium.
Some systems (like under-sink or countertop ionisers) use electrolysis to actively separate the water stream into alkaline and acidic fractions, achieving higher pH levels. Most pitcher and gravity filters use the passive remineralisation method, which is more affordable and requires no electricity or plumbing.
While the scientific evidence for health benefits of alkaline water is still developing, many users report improved taste, better hydration, and cleaner-tasting water overall. Some smaller studies suggest potential benefits for acid reflux sufferers and bone health, though these are not yet conclusively proven by large-scale clinical trials.

Review: Hskyhan 3.5L 7-Stage Alkaline Water Filter Pitcher
Rating: 4.2 / 5 | Best for: Budget-conscious households wanting reliable alkaline filtration
The Hskyhan 3.5L Alkaline Water Filter Pitcher is one of the most popular alkaline filter pitchers on Amazon Australia, and it’s easy to see why. For under $50, you get a well-rounded 7-stage filtration system that genuinely improves the taste and quality of tap water while raising the pH to a noticeably alkaline level.
The seven filtration stages include a PP cotton pre-filter (removes sediment), activated carbon (removes chlorine and odour), ion-exchange resin (softens water and removes heavy metals), and multiple layers of mineral media including maifan stone, tourmaline, and alkaline mineral balls. The combination effectively raises pH to between 8 and 9.5 while infusing small amounts of calcium, magnesium, and potassium.
The 3.5L capacity is generous — large enough to handle a family of three to four without constant refilling. It comes bundled with two replacement filters, which is excellent value and keeps you going for four to six months before you need to buy more. The BPA-free plastic construction is lightweight and easy to handle, though it does feel noticeably less premium than stainless steel options.
Setup is straightforward: soak the filter for 15 minutes, rinse, and you’re ready to pour. Filtration speed is average at about 16–20 minutes for a full 3.5L fill, which means a little planning ahead is needed. Keep it in the fridge for chilled alkaline water on demand.
✅ Pros
- Excellent value — 2 filters included
- 7-stage filtration with mineral enrichment
- 3.5L large capacity
- Raises pH to 8.0–9.5
- No electricity or plumbing needed
- Compact, fridge-friendly design
❌ Cons
- Plastic build feels less premium
- Filtration can be slow (15–20 min for full fill)
- Replacement filters not always easy to find locally
- Handle could be sturdier
Bottom line: If you’re new to alkaline water filters and want to try one without a big upfront investment, the Hskyhan pitcher is a fantastic starting point. It delivers real filtration performance at an entry-level price, and the two included filters sweeten the deal considerably.
Review: pH Vitality Stainless Steel Alkaline Water Filter Pitcher
Rating: 4.6 / 5 | Best for: Those wanting a stylish, durable alkaline pitcher for daily use
The pH Vitality Stainless Steel Alkaline Water Filter Pitcher by Invigorated Water is our Editor’s Choice pick for 2025. It steps up from the plastic competition with a sleek, brushed stainless steel exterior that not only looks impressive on a kitchen bench but also means no plastic leaching into your filtered water — a concern for some health-conscious buyers.
The 1.9L capacity is more compact than the Hskyhan option, making it ideal for individuals, couples, or those with limited fridge space. The multi-stage alkaline filter inside raises the pH of tap water to up to 9.5 while removing chlorine, chloramines, heavy metals, and other common contaminants. The result is noticeably cleaner, smoother-tasting water that many users say they genuinely prefer over bottled water.
Invigorated Water is a well-established brand in the alkaline water space, and their filters have earned a strong reputation for consistency. The cartridge lifespan is around 150L (two to three months of typical use), and replacement filters are easy to source online through Amazon Australia and eBay. The stainless steel body is dishwasher safe (minus the filter), which is a handy practical advantage.
The pour spout is designed for a clean, drip-free experience, and the ergonomic handle makes it comfortable to use at any fill level. The only real trade-off is the 1.9L capacity — if you have a larger household, you may find yourself refilling more often than you’d like.
✅ Pros
- Premium stainless steel construction
- Raises pH up to 9.5
- Drip-free ergonomic pour spout
- Dishwasher safe (body)
- Trusted brand with good filter availability
- No BPA or plastic water contact
❌ Cons
- Smaller 1.9L capacity

Review: Invigorated Water pH Recharge Glass Alkaline Dispenser
Rating: 4.5 / 5 | Best for: Families, offices, or those wanting a statement countertop water station
The Invigorated Water pH Recharge is the premium option in our lineup — a stunning 7.5L (2-gallon) countertop glass and wooden dispenser that brings a touch of Scandi-inspired design to your kitchen. It’s the kind of item that gets noticed by guests, but it also delivers excellent alkaline filtration performance to back up its good looks.
The borosilicate glass reservoir is heat-resistant, shatter-resistant, and entirely free of plastic in the water contact zone — a significant advantage for those wanting to eliminate all potential chemical leaching.

Setup is very simple: insert the filter into the upper tank, fill with tap water, and gravity does the rest over a few hours. There is no electricity, no plumbing, and no ongoing mechanical maintenance — just gravity filtration at its most elegant. The only real drawback is the price premium and the relatively long fill-to-ready time with such a large capacity tank.
✅ Pros
- Beautiful glass + wood design
- Huge 7.5L capacity
- No plastic water contact
- Easy-pour tap dispenser
- Great for families or offices
- Longer 200L filter life
❌ Cons
- Higher upfront cost

Buying Guide: What to Look For in an Alkaline Water Filter
1. Capacity
Think about how much water your household drinks daily. A single person or couple will likely manage well with a 1.9–2L pitcher. Families of three or more should look at 3.5L pitchers or larger countertop dispensers (7L+) to avoid constant refilling.
2. Filtration Stages
More stages don’t always mean better results, but look for a system that includes activated carbon (for chlorine removal), ion-exchange media (for heavy metals and hardness), and mineral/alkaline media (for pH raising and remineralisation). A 5–7 stage system covers most households’ needs.
3. pH Level Achieved
Most quality alkaline filters raise tap water to a pH of 8–9.5. Higher isn’t necessarily better for drinking water — a pH of 8–9 is a practical and well-regarded range. Avoid products that claim to reach pH 10+ through gravity filtration alone, as this is unlikely without electrolysis.
4. Filter Life and Running Cost
Check the rated filter life (usually 100–200L or 2–3 months) and the replacement cartridge price. Budget pitchers may have cheap upfront costs but expensive or hard-to-find replacement filters. The real cost of ownership is the filter cartridge — factor this into your comparison.
5. Material
BPA-free plastic is fine for most users, but if you prefer zero plastic contact, look for stainless steel or glass options. Both are more durable and don’t risk any trace chemical leaching, though they cost more upfront.
6. Ease of Use
Consider how the filter is filled, how fast it flows, and how easy it is to pour. Pitchers with a wide fill opening are easier to top up under a tap. Dispensers with a tap are more convenient for families. Some pitchers have indicator lights for filter change reminders — a handy feature.
Frequently Asked Questions
Is alkaline water actually good for you?
The science is still evolving, but there is some evidence that alkaline water may benefit people with acid reflux, and some small studies suggest potential benefits for bone density. Most users report improved taste and say they drink more water as a result — which is itself a genuine health benefit. Alkaline water is not a cure or treatment for any medical condition, but for most healthy adults it is perfectly safe.
How often do I need to replace the filter cartridge?
Most alkaline filter pitchers use cartridges rated for 100–200 litres, which typically equates to every 2–3 months for an average household. It’s important not to leave cartridges in use beyond their rated life, as bacteria can accumulate in spent filter media. Many pitchers include a filter life indicator or change reminder.
Does an alkaline filter remove fluoride?
Standard alkaline filter pitchers do not effectively remove fluoride. If fluoride removal is important to you, you’ll need a system with an activated alumina or reverse osmosis stage specifically designed for fluoride, such as an under-sink RO system with an alkaline remineralisation post-filter. Some premium gravity filter systems (like the zazen or Earths Water systems) include media rated for partial fluoride reduction.
Can I use an alkaline water filter with tank water or bore water?
Alkaline filter pitchers are designed for pre-treated mains tap water and are not suitable for untreated tank water, bore water, or water from unknown sources. These sources may contain bacteria, viruses, or high levels of contaminants that require a more robust treatment system (such as UV sterilisation or an ultrafiltration system). Always use a pitcher filter with a known-safe source water.
How long does it take to filter water in a gravity pitcher?
Gravity alkaline pitchers typically filter water at around 0.5–1.5L per hour, depending on the filter type and water temperature. A full 3.5L pitcher may take 15–20 minutes to fully filter. Keeping a filled pitcher in the fridge means you always have a ready supply of cold alkaline water without waiting.
What’s the difference between an alkaline filter and a water ioniser?
A water ioniser uses electrolysis — an electric current passed through water between platinum-coated plates — to actively separate water into an alkaline stream and an acidic stream. This can achieve higher pH levels (9.5–11) and also produces molecular hydrogen. Ionisers cost significantly more (typically AU $1,500–$5,000+). Alkaline filter pitchers use passive mineral media to raise pH through remineralisation, achieving pH 8–9.5 at a fraction of the cost with no electricity needed.
Where can I buy replacement filter cartridges in Australia?
Replacement cartridges for the brands reviewed here are available on Amazon Australia and eBay Australia. Many are also sold through Australian specialty water filter retailers online. Always check that you’re buying the correct cartridge model for your specific pitcher, as cartridges are not universally interchangeable between brands.
Final Verdict
All three alkaline water filters reviewed here deliver genuine results: cleaner, better-tasting water with a measurably raised pH. Your choice comes down to budget, capacity needs, and how much you value build quality and aesthetics.
