Natural filtration without use of chemicals 

The filtration process is purely mechanical and uses water pressure, while forgoing the need for chemicals and electricity entirely. The water passes through a three-stage filtration system consisting of a pre-filter, a microfiltration membrane, and activated carbon.

1. Pre-filter

Physically retains solids, such as sand and larger suspended particles.

2. Microfiltration membrane

Blocks up to 99.9 % of bacteria and germs. Also effective against solids, including microplastics and rust particles, up to 0.3 micron (= 0.003 millimeters) in diameter.

3. Activated carbon (block)

Activated carbon block filters are made from fine coconut shells because they provide an exceptionally large surface area and thus an enormous capacity for retaining pollutants. This is how the activated carbon binds dissolved solids such as pharmaceutical residues, pesticides, hormone-like substances, etc. Organic substances and chlorine are also significantly reduced, which improves taste and smell.

Seccua filtered drinking water retains valuable minerals and salts
