0,2 Micron Sediment filter
We would use the 0,2 micron cartridge where it acts as a secondary filter, especially at your laundry, where you wish to keep your linen and towels white for as long as possible. This would typically be fitted to a single stage system after a big blue system.
The sediment filters are available in 4 filtration sizes and are the filters that works the hardest requiring the most frequent replacement.
