Pure, transparent water with no compromises or concerns.
A hot tub’s quality depends not on the number of jets but on its ability to keep water perfectly clean now, tomorrow, and even a year later. Sand filtration uses the same technology as professional pools, guaranteeing consistent water quality, lower operating costs, and maximum comfort.
The water remains clean even with regular use.
Sand filtration captures smaller particles than standard cartridge filters, keeping water clear over time by preventing turbidity and microparticles, even with heavy use. You don’t need to disassemble or rinse the filter frequently, since there’s no contact with captured particles. Just use clean water and enjoy peace of mind.
Lower operating costs. Long-term savings.
Traditional systems demand frequent cartridge filter replacements, while sand filtration provides a cost-effective, long-term solution. Its durable filter media lasts for a long time, and maintenance is simple—just switch the valve to backwash mode. This reduces costs and enhances convenience.
So, how does the system work?
Water flows through silica sand or modern filter media layers, trapping even the tiniest impurities. Purified water then returns to the hot tub. The system works reliably and efficiently, requiring little maintenance. As a result, water quality remains steady without fluctuations.
Water and energy savings
- ✔ Higher filtration efficiency results in less frequent water changes.
- ✔ You conserve hundreds of litres of water and reduce the expenses associated with reheating it.
- ✔ This enhances the cost-effectiveness and eco-friendliness of hot tub operation.
What you should know:
Sand filtration is a dedicated unit placed near the hot tub or in a utility room. Although the initial cost is higher than basic systems, it is compensated over time through lower operating expenses, better hygiene, and minimal upkeep.
Common concerns – and what really happens
„Sand filtration leads to considerable heat loss.“
Modern systems are contained within a thermally insulated enclosure capable of withstanding temperatures as low as -30°C, resulting in minimal heat loss.
„Rinsing wastes water.“
Rinsing uses approximately 10–15 litres of water each year, which is a very small amount in the context of total operation.
Who benefits most from sand filtration?
✔ Clients who regularly use their hot tub.
✔ It is also suitable for households that use more water.
✔ Clients seeking minimal maintenance will also find it advantageous.
✔ It is also suitable for clients considering the long term.
Sand filtration is more than just an accessory; it represents a commitment to higher standards of home wellness.
