Don’t strip your water to filter it.

The system selectively refines treated tap water through three complementary filtration stages.

KDF and coconut-shell carbon provide the initial pre-treatment stage. Silver-infused activated carbon further refines chlorine-related taste and odor, while the final 0.01 μm hollow-fiber membrane creates a physical barrier against fine suspended particles, cysts, parasites, and bacteria.

Unlike filtration methods designed to remove nearly all dissolved material, the Python system allows naturally occurring calcium, magnesium, and other dissolved mineral salts to remain where present.

Each stage performs a different role so the final membrane does not have to work alone.

A 0.01 μm membrane creates an exceptionally fine physical barrier for treated drinking water.

Ultrafiltration at this scale is used to retain suspended particles, turbidity, cysts, parasites, and bacteria that are larger than the membrane pores.

Some viruses may also be reduced depending on their size and the complete system configuration. The Python system is designed for water that has already been treated by a municipal water supplier rather than untreated or microbiologically unsafe source water.

Chemical refinement is handled primarily by the KDF and activated-carbon stages. The ultrafiltration membrane itself works principally through physical size exclusion.

No. The Python system is designed to preserve the naturally occurring mineral profile of treated tap water.

Dissolved calcium and magnesium ions are much smaller than the suspended particles and microorganisms targeted by the ultrafiltration membrane. They therefore remain in the water where they were already present.

This is the central principle of selective filtration: reduce what does not belong without demineralizing the water by default.

For treated municipal tap water, ultrafiltration is often the better fit when the goal is cleaner daily drinking water without removing the existing mineral profile.

The appropriate system depends on the source water. Ultrafiltration is optimized for treated municipal water. Reverse osmosis is more appropriate when desalination or broad dissolved-ion reduction is required.

The system is not designed to substantially lower total dissolved solids—and that is intentional.

A TDS meter counts dissolved mineral salts, including naturally occurring calcium and magnesium. It does not distinguish between desirable minerals and substances a customer may want to reduce.

A lower TDS reading therefore does not automatically mean better drinking water. Python focuses on selective refinement rather than treating the lowest possible TDS number as the objective.

Yes. The carbon stages are specifically designed to refine chlorine-related taste and odor.

Coconut-shell activated carbon provides a high internal surface area that adsorbs compatible compounds as water passes through it.

The combination of pre-treatment, activated carbon, and final ultrafiltration is designed to produce cleaner-tasting water without stripping away the dissolved minerals that contribute to its natural character.

No. The Python system provides direct-flow filtration without a storage tank or reject-water line.

Incoming water passes through the three filtration stages and continues directly to the drinking-water outlet. There is no separate stream of concentrated reject water being sent down the drain during normal filtration.

The tankless configuration also avoids storing previously filtered water under the sink before it is consumed.

The Python Nano Ultrafiltration System is designed primarily for treated municipal tap water.

It is a strong fit when the source water has already been disinfected and the goal is further refinement, improved taste, physical filtration, and mineral preservation at the point of use.

Private-well water should be laboratory tested before selecting a treatment system. Depending on the results, well water may require additional sediment treatment, disinfection, softening, or dissolved-contaminant reduction before ultrafiltration.

The system is installed under the sink as a direct-flow, point-of-use drinking-water filter.

Because it does not require a storage tank or reject-water connection, the system uses a cleaner and more direct plumbing configuration than a traditional tank-based reverse-osmosis installation.
