Can Prill Beads Be Used in Tap Water? Yes — Here’s How

Magnesium prill beads are one of the simplest ways to improve your tap water at home — no plumbing, no filters, no ongoing cartridge costs. Here’s what they actually do, how to use them, and what to realistically expect.

Can Prill Beads Be Used in Tap Water?

Yes — prill beads are designed to be used with tap water. That’s their primary purpose. You simply place the bag of beads in a glass or ceramic container, fill with tap water, and let them work. They’re also effective with filtered water, distilled water, or rainwater.

What Do Prill Beads Do?

Magnesium prill beads are made from magnesium oxide. When placed in water, they:

• Raise the pH — making the water mildly alkaline (typically around pH 7.4–8.0)
• Add magnesium — a beneficial mineral that many Australians don’t get enough of from diet alone
• Improve taste — water treated with prill beads has a softer, smoother flavour that most people prefer to straight tap water
• Reduce surface tension — which may improve cellular hydration

Important note: prill beads are not a water filter. They don’t remove chlorine, fluoride, bacteria, or heavy metals. For comprehensive filtration, use them alongside a benchtop water filter or reverse osmosis system.

How to Use Magnesium Prill Beads

1. Rinse the bag of prill beads under running water before first use to remove any loose particles.
2. Place the bag in a glass or ceramic container (up to 5 litres).
3. Fill with drinking water and leave for 24 hours before first use.
4. After that, drink one-third to one-half of the water and refill — the beads will continue treating the new water within a few hours.
5. Store at room temperature, away from direct sunlight (sunlight can encourage algae growth in the container).

How Long Do Prill Beads Last?

Prill beads don’t dissolve and can last for years with proper care. Their ability to raise pH gradually reduces over time, particularly when used with acidic water. Most users find they remain effective for 12–24 months of regular use.

Other Uses for Prill Beads

• Add to bath water for a softer feel
• Soak fruit and vegetables before eating
• Use in cooking water
• Add to a humidifier
• Extend the life of cut flowers
