Seccua MK7 — The compact water filtration system for perfect drinking water straight from the tap

Good hydration is crucial for our health and physical well-being and drinking water from the tap is significantly cheaper than the bottled alternative, regardless of whether it comes in glass or in single-use or reusable plastic. Why should we have to continue producing mountains of waste when we could significantly reduce our environmental footprints while protecting the environment and climate instead?

We can’t forget that the water that flows from our faucets isn’t necessarily clean, however. Waterborne pathogens and pollutants can contaminate tap water before it reaches our homes.

The Seccua MK7 under-sink water filtration system offers an instant solution. It takes just a few easy steps to install under the kitchen or bathroom sink at the point of use and guarantees perfect drinking water from the moment you turn on the tap.

Advantages of a Seccua MK7 under-sink water filtration system

Significantly reduce pathogens in drinking water

Old pipework, stagnant or warm water, and dead-legs all jeopardize water quality because they allow pathogens to multiply exponentially. The Seccua MK7 under-sink water filter significantly reduces microbial contamination in drinking water.

Remove microplastics and other harmful substances

Seccua MK7 removes microplastics up to 99 percent and rust. It also protects against dissolved substances such as pesticides, pharmaceutical residues and hormones, while preserving important minerals such as calcium and magnesium.

Reject bottled water’s miserable environmental record

Drinking water from the tap is not only easy on the wallet but on the climate and the environment as well. It takes a thousand times more energy to produce, package, and transport bottled water than it does to properly treat drinking water.

Cut down on plastic waste

According to Environmental Action Germany (DUH), around 2 million disposable plastic bottles are used in the country every single hour. That amounts to more than 47 million bottles per day. By drinking water from the tap, you can help cut down on this immense consumption of resources.

Perfect water to keep you fit

If you are someone who works out and wants to maintain high levels of mental and physical performance, then you need to drink a lot of liquid in order to replace the fluids you lost sweating. Drinking water is not only refreshing, it’s also sugar and calorie free.

Delicious drinking water for young and old alike

You can rely on the activated carbon in the Seccua MK7 to remove any unpleasant odor or taste, thereby maintaining drinking water from the tap water as the best thirst-quenching alternative in your home. After all, proper hydration is vital for the human body at any age.

Natural filtration without use of chemicals

Three-stage microfiltration for perfect drinking water.

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.
