The FROST 2ST consists of 2 stages of water purification.

1st Stage: Aqua Filter AIPRO polypropylene filter. The In-line sediment filter cartridge removes sediments such as sand, silt, rust, and suspended solids. It is installed in compact systems and reverse osmosis units. Connection with a 6.3mm diameter tube. Available sizes: 2"x10". Available micron: 5. Operating Temperature: 2°C - 45°C. Long-term use: 3-6 months.

2nd Stage: In line Activated Carbon filter from Aqua Filter, size 10"x 2". It provides protection against chlorine, pesticides, and other organic contaminants, improving the taste and odor of the water. The construction method of activated carbon filters ensures maximum water flow, as the chemical medium is in granular form. It is used as a carbon filter in water coolers and as the final stage in under-sink reverse osmosis systems (post carbon filter). Their lifespan ranges from 4 to 6 months, depending on the water quality. It connects with a 6.3mm tube.
