Frequently Asked Questions

Everything you need to know about your Vortex water system

The AquaVive RO membrane is designed to last up to 12 months, depending on your water quality and daily usage.

Replacing it on time ensures consistent filtration performance and keeps your water as clean and safe as possible.

This filter is specifically designed for the Vortex Air H2 Oasis™ Elixir system.

For proper performance and fit, it should only be used with compatible H2 Oasis units.

Not at all.

The filter is designed for quick, tool-free replacement using a twist-in system. Simply remove the old filter and insert the new one in seconds.

The AquaVive RO membrane uses 0.0001-micron reverse osmosis filtration to remove up to 99.99% of contaminants.

This includes:

  • Heavy metals (like lead and mercury)
  • Chemicals (such as chlorine and VOCs)
  • Fluoride
  • Microplastics and other fine impurities

This is the core filtration stage that purifies your water at a molecular level.

Yes. Once the water has been filtered of all impurities, it will taste and smell noticeably better — the difference will be even more obvious if your unfiltered tap water was particularly poor to begin with.

Yes. By removing chlorine, chemicals, and impurities that affect flavor, this filter delivers cleaner, fresher-tasting water from the first use.

The Elixir works effectively in most UK homes. However, in very hard water areas, the high mineral content can reduce filter lifespan and may affect the machine's performance. 

We recommend checking your local water hardness before purchasing — a pre-filter or water softener may be needed to get the best out of your Elixir.
