Premium Multi-Stage Media
DUAL Filtration System

The Prime Water dual filtration system is made up of multi level stage specialized media filter and a premium activated carbon filter.

The Premium Activated Carbon filter is structured to improve the reduction of heavy metals and fluoride found in many city water sources. The silver activated carbon portion of the filter kills bacteria and keeps them from growing within the filter and being passed through to the electrolysis chamber.

The multi level stage sediment filter reduces additional sediment particles in the water maintaining the life and performance of your water ionizer.

FAQs

1) How does the PRIME 1301S work and what are the benefits?

The PRIME 1301S filters and ionizes tap water through dual filtration and electrolysis, producing alkaline, neutral, or acidic water.

  • Alkaline water – for daily drinking, crisp taste, antioxidant properties.
  • Acidic water – for external use such as cleaning, skin care, and sanitation.
  • Purified water – filtered but non-ionized, ideal for infants or when taking medication.

2) What is the difference between the undercounter and countertop versions?

  • Undercounter: the unit is installed under the sink, controlled through a stylish digital faucet with a touch display. Best for modern kitchens with a clean look.
  • Countertop: the unit sits on the counter next to the sink with its own control panel.

Both produce the same quality of water, the difference is only in design and installation style.


3) How much space and what conditions are required for installation?

  • Unit size: approx. 33 cm (W) × 34.7 cm (H) × 15 cm (D).
  • Requires a 110/220 V power outlet under the sink.
  • Faucet hole diameter: 33 - 35 mm (standard sink/blade hole size).

Installation can be done DIY, but a plumber is recommended for drilling and proper drainage connection.


4) What performance levels does it offer?

  • Max flow rate: up to 3 L/min.
  • pH range: approx. 7.5 - 10 for alkaline, 3.5 - 6.5 for acidic (depending on source water).
  • Advanced settings: multiple programmable pH and ORP levels to fine-tune results.
  • Electrolysis chamber: premium titanium plates coated with platinum, designed for efficiency and durability.

5) What filters does it use and how long do they last?

The PRIME 1301S is equipped with two internal filters that remove chlorine, heavy metals, and impurities.

  • Average lifespan: around 6 months (based on ~20 L/day usage and water quality).
  • The digital faucet shows a clear replacement indicator.
    Filters are user-replaceable and easy to change.

6) Is it compatible with all water types?

  • Municipal tap water – fully compatible.
  • Well or hard water – recommended to use pre-filtration and ensure potability.
  • Reverse Osmosis (RO) water – works only if a remineralization cartridge is added, since ionization requires minerals.

7) How is acidic water discharged?

Acidic water is not for drinking. It is discharged into the sink or connected to the drain pipe. Many users also collect it separately for cleaning or cosmetic use.


8) What are the maintenance and running costs?

  • Filters: usually replaced twice a year, depending on usage.
  • Electricity: very low consumption, only while ionizing.
  • Optional pre-filter may be required in areas with very hard water.

9) Is it safe for children or while taking medication?

  • Infants and toddlers: should drink purified (non-ionized) water.
  • Adults: start with a lower alkaline level and gradually increase.
  • Avoid alkaline water 30 - 60 minutes before or after medication.

10) What warranty and certifications does it have?

  • Warranty: up to 5 years (depending on distributor).
  • Certifications: compliant with CE and EMC standards, ensuring safety and product quality.
