HYDRA BIG TRIO Rainmaster 1” - 20 inch Household Water Filter

POWERFUL BIG TRIPLE filter housing with one-piece head

This filtration system treats the water at a high concentration cost-effectively and filters out contaminants as well as fine particles from the water.

This works through the self-cleaning/backwash pre-filter with 90 microns, an FA pre-filter with 25 microns, and a final water treatment with the CB CARBON cartridge.

The CTO 20 BIG 10 mcr - Activated Carbon Block consists of compressed activated carbon and filters contaminants from the water such as chlorine, organic contaminants, light hydrocarbons, solvents, pesticides, insecticides, oils and flavors, taste impairments, odor impairments, fine particles (rust, lime flakes, sand, flakes) and suspended solids.

The filter cleans the water to 10 microns.



Usage, Scope, Dimensions:

The 3-stage water treatment system is designed to be very space-saving and easy to assemble.

The HYDRA TRIO household water filter features a drain funnel/backflow preventer to protect the drinking water supply.

The HYDRA TRIO household water filter is used for the filtration and treatment of drinking water, household water, and wastewater, and serves to protect fittings, pumps, water tanks, and other technical systems as well as the pipelines.

The individual filtration stages:

1 x RLH 90mcr HYDRA BIG - Sediment Filter Polyester Mesh
Self-cleaning Pre-filtration Cartridge – RLH: 90 MIC
filters sand and other particles larger than 90 microns
Lifespan: approx. 12-24 months (depending on water quality and flow rate)


1 x FA 20 Big SX 25 Micron - Sediment Wound Filter Polypropylene

Wound filters are powerful sediment filters for removing sand, dust, rust, and other particles. The particularly uniform winding of the polypropylene thread during production results in a compact cartridge with a large effective filter surface.
Lifespan: approx. 6 months (depending on water quality and flow rate)

1 x CTO 20 BIG 10 mcr - Activated Carbon Block
filters chlorine, organic pollutants, light hydrocarbons, solvents, pesticides, oils and aromas, taste impairments, odor impairments, fine particles (rust, lime flakes, sand, flakes) and suspended solids.
Lifespan: approx. 6 months (depending on water quality and flow rate)


The filter system is originally packaged, with filter housing, a housing key, a wall mount, screws, and three filter cartridges.
