Alka City Total
A complete, balanced mineral filtration system for city water, combining targeted fluoride reduction with everyday filtration and mineral restoration.
The Alka City Total is designed specifically for treated town water, where chlorine, fluoride, and common contaminants are present.
This system combines multi-stage filtration with a dedicated FluorEx stage to reduce fluoride and arsenic, alongside carbon and ultrafiltration to improve taste, reduce chemicals, and support everyday water quality.
Unlike many conventional fluoride filters that rely on activated alumina, the FluorEx stage uses a mineral-based media, designed to reduce contaminants without aluminium-based filtration materials.
After filtration, the Alka Spring stage restores essential minerals such as calcium and magnesium, improving taste and creating a more balanced, natural drinking experience.
This makes the Alka City Total a complete, everyday system for households wanting a reliable improvement in water quality, while maintaining a more local mineral profile.
What does this system remove?
- Chlorine and treatment chemicals
- FluorEx filter reduces fluoride and arsenic using mineral-based media (no alumina)
- Heavy metals such as lead and other common metals found in plumbing
- Microplastics and fine particles
- Reduces microorganisms, including chlorine-resistant cysts (e.g. Giardia, Cryptosporidium)
- Common contaminants found in town supply
- Improves taste and clarity
What this does not do
- Does not provide the same level of removal of dissolved contaminants (e.g. nitrates, PFAS) as reverse osmosis
- Not equivalent to reverse osmosis filtration
Where this system fits
- Complete system for most city water conditions (REMOVE + RESTORE)
- Balanced everyday filtration and mineral restoration
- A step below reverse osmosis in filtration depth
- Designed for most treated town supply
When should I consider a different system?
- If you are concerned about nitrates or PFAS → PureRevive
- If your water quality is unknown or high-risk → PureRevive
- If you want maximum contaminant removal → PureRevive
