Filtration Performance
Coldstream FTO+: Advanced Filtration for Pure and Safe Water
The Coldstream FTO+ filters incorporate dual-filtration technology to deliver exceptional water quality. Their design consists of:
Outer ceramic shell: Blocks microbiological contaminants, microplastics, PFAS (forever chemicals), and suspended particles.
Granular Activated Carbon (GAC) core: Reduces a wide range of chemical substances, enhancing the taste and purity of the water.
What Contaminants Are Removed?
- Bacteria and viruses: Including Klebsiella terrigena, rotavirus, and other harmful pathogens.
- Heavy metals: Lead, mercury, aluminum, arsenic, copper, nickel, zinc, silver, chromium, and more.
- Fluoride: Effectively reduces fluoride without requiring additional filters.
- Bad taste and odors: Chlorine, hydrogen sulfide, and volatile organic compounds (VOCs).

Filter Replacement:
The Coldstream FTO+ filters are designed to provide optimal filtration for an extended period.
- Recommended lifespan: 1,500 liters per filter.
- Total capacity with 2 filters: 3,000 liters, or about 1 year of use based on 8L/day.
When should you replace your filters?
The replacement frequency depends on your daily water usage and the quality of your water source. Each filter will produce safe water for up to 1,500 liters, so make your calculations accordingly. Even after exceeding their recommended lifespan, filters will continue to remove contaminants, but their effectiveness will decline.
Our advice: To ensure consistently pure and great-tasting water, always keep an extra set of replacement filters on hand.
Choosing the Right Size
Choosing the right capacity for your AQUA Coldstream system is essential to ensure a constant supply of pure, filtered water. The gravity filtration process delivers exceptional quality but takes time. To avoid long waits, it's important to select a model suited to your daily consumption. Here are some key considerations to help you make the best choice for both present and future needs.
Which Capacity is Best for Your Needs?
Your water consumption varies depending on the number of users and peak usage times. It is recommended to choose a system that meets your needs during peak hours:
- At home: Ensure enough water is available for meals and cooking.
- At the office, gym, or yoga studio: Avoid shortages during breaks when multiple people want to hydrate at the same time.
- During gatherings or events: A larger model allows you to host guests comfortably without running out of water.
Plan for Future Needs
An AQUA Coldstream system is a long-term investment. The stainless steel canisters are built to last a lifetime, provided they are well-maintained. Before purchasing, consider the following questions:
Will your family grow in the coming years?
Could your water consumption increase over time?
Would you prefer a larger capacity for greater convenience?
By anticipating these factors, you can make a smart decision and avoid needing to upgrade your system too soon.
6L, 9L, or 12L: Which Option is Best?
The price difference between an AQUA Coldstream 6L, 9L, and 12L is minimal compared to the product's lifespan. Consider these points when deciding:
- The 6L model is ideal for one or two people, but it is limited to 2 filters.
- The 9L and 12L models can accommodate up to 4 filters, providing a faster filtration rate.
- If you are unsure between two sizes, choose the larger model to offer more flexibility in the future. This way, you will never run out of pure AQUA Coldstream water!
