Atlas BIG F PRO 156 filter set: replacement sediment cartridges (20 µm and 1 µm) for the Atlas Filtri BIG F PRO 156 system with UV sterilisation.

replacement cartridges from Atlas Filtri for the BIG F PRO 156 system with UV sterilisation
The Atlas BIG F PRO 156 filter set contains replacement sediment cartridges for the two-stage filtration system Atlas Filtri BIG F PRO 156 with UV-C water treatment. The system has two filtration stages: the first cartridge (TS BIG, 20 µm) traps sand, rust and coarse particles, and the second (CPP BIG, 1 µm) traps fine particles. After them, the water flows through a UV-C reactor, which according to the manufacturer physically inactivates microorganisms.
The two cartridges in the set are 10″ BIG in size (according to the page, 250 mm in length and 118 mm in diameter). Without replacing the cartridges, UV sterilisation does not work reliably, because particles in the water shade the UV light.
How does the system work and where are the two cartridges?
The Atlas BIG F PRO 156 filters water in two stages, followed by UV-C treatment. The first stage with a 20 µm cartridge protects the second, which with 1 µm filtration prepares the water for UV light, which is effective only in clean water.
The UV lamp is not part of the set. The 156 system uses a low-pressure UV lamp of 67 W with a service life of 9,000 hours, so replace it when that time has passed. The filter set does not replace the UV lamp and does not remove chlorine or dissolved substances.
When to replace it and what to add
Use the Atlas BIG F PRO 156 filter set for regular replacement of cartridges in the Atlas Filtri BIG F PRO 156 system. Replace the cartridges when you notice a drop in flow or pressure, or according to the quality of the water you are filtering. Replace the UV lamp separately after 9,000 hours.
If you need an additional stage, see the post carbon cartridge. You will find other cartridges for 10″ house filters in the category cartridges and spare parts for Big Blue 10″.
When to replace the two cartridges
The manufacturer does not state a fixed interval for the cartridges. Replacement depends on water quality. Replace them when the flow or pressure drops or the water visibly becomes cloudy. With water that contains a lot of sand or rust, this means more frequent replacement. Before replacing, switch off the system and shut off the water supply.
