Our Very 1st
Project,

Automatic
Water Filter Pitcher

"Why should clean water be so complicated?"

Most people still rely on heavy bottled water, bulky installations, or complex purifiers just to enjoy safe drinking water. We believed there had to be a better way.

At Sflux, we started with a simple observation: access to clean water should be effortless.

Instead, many households were struggling with complicated installations, carrying plastic bottles, and frequent maintenance. We set out to redesign this experience from the ground up.

The Problem We Saw

We began by purchasing and testing every major water pitcher on the market.

What we found were common flaws:

Slow natural gravity flow

Most pitchers depended on gravity alone, resulting in slow flow rates (around 0.2 LPM) and leaving stagnant water in the reservoir.

Inconvenient filter

replacement

The process often involved shaking the filter in water and rinsing it multiple times before use.

Low-performance filters

Conventional pitchers mostly relied on granular activated carbon and ion-exchange resins, offering only basic taste improvement and chlorine removal.

Unhygienic filter replacement

Users had to reach inside the raw water tank to replace filters, leading to inconvenience and secondary contamination risks.

Mixing of raw and purified water

Poor internal separation often led to cross-contamination, where raw water could mix with purified water during pouring.

The Design Journey

01.

From weak to powerful filtration

02.

From contamination risks to hygienic design

03.

From mixing to complete separation

04.

From slow gravity flow to efficient pumping

These insights shaped the foundation of Sflux.

2019 - Blow Mold Design

First concept models with integrated top units.

We realized internal filters made the pitcher bulky and less user-friendly.

01

Installation free,
No power supply,
Rechargeable

The battery lasts 2~3months per charge, which is very convenient to use either indoor or outdoor.

02

Fast filtration technology
in just 2 minutes

There is a pump under the base, which allows fast filtration of water within 2 minutes.

03

Hygienic and easy
filter change

It's just that simple to have a quick snap of filter, and you can replace it with a new filter in a blink!

04

Smart keep up,
Battery & filter life indicator

Counts the overall filtration time for filter replacement.

It also alarms you when it needs charging.

05

High quality,

long filter life

Three types of filter, which allows high removal rate such as bacteria and virus.

Filter can be used 500~800L depend on the local water quality.

06

Hygienic,

leak-safe Safeguards

Counts the overall filtration time for filter replacement.

It also alarms you when it needs charging.
