[PenChuNiu] Full Link Water Purification Protection Series - Pure Protection from Source to End "

Series concept:
Faced with the increasingly complex water quality environment, we have established a multiple protection system of "pre protection+core purification+bathing and skincare", aiming to provide a comprehensive healthy water solution for the whole family from drinking to washing.

Core products:

Function: Intercept large particles of impurities such as sediment and rust, and protect water related electrical appliances in the home.

Function: Deeply remove residual chlorine, heavy metals, and organic pollutants.

Technology: Using imported KDF+pickled coconut shell activated carbon combination, certified with NSF42/53 dual certification, effectively improves taste and retains beneficial minerals.

Function: To solve the problems of dry skin and damaged hair caused by residual chlorine in bath water.

Technology: built-in calcium sulfite ball and VC essence, instantly neutralize residual chlorine, release skin care factors, and make bathing a SPA level enjoyment.

Scientific grading filtration not only ensures that the effluent quality meets the standard, but also extends the service life of the precision filter element at the back end through pre protection, reducing the overall cost of use by 30%. All products comply with national standards, allowing you to use them with peace of mind.

Our company's household pre filter is positioned as the "primary gatekeeper" for whole house water use, mainly used at the front end of the household main water pipe, aiming to intercept large particles such as sediment, rust, and insect eggs with a diameter of over 40 microns. Its wide range of applications covers the following three major fields:

1. Whole house water related appliance protection

Effectively safeguard precision equipment such as water heaters, wall mounted boilers, underfloor heating systems, and smart toilets to prevent pipeline blockages, valve core failures, and decreased thermal efficiency caused by impurity accumulation; As an ideal pre-treatment partner for water purifiers and softeners, it significantly extends the service life of the backend filter element and reduces maintenance costs.

• Hot water system: water heater (gas/electric), wall mounted boiler, underfloor heating water separator, heat sink. Prevent the mixing of scale and impurities from blocking the pipeline and improve heat exchange efficiency.

• Washing equipment: washing machine, dishwasher. Protect the inlet valve from being stuck by sand particles, extend the life of the motor and water pump, and improve the cleanliness of clothing and tableware.
• Smart bathroom: smart toilet, thermostatic showerhead, high-end faucet. Prevent small particles from blocking the nozzle or valve core to avoid dripping faults.
• Deep water purification equipment: central water purifier, water softener, kitchen RO reverse osmosis water purifier. As a pre filtration stage, it significantly reduces the burden on the backend filter element, extends the replacement cycle of expensive filters, and reduces long-term usage costs.

2. Ensuring high-quality domestic water supply

Suitable for daily washing, bathing, laundry, and dishwashing scenarios. By removing suspended particles from water, reducing water stains, protecting skin health, and enhancing clothing cleanliness and tableware shine.

• Daily grooming: The filtered water is used for washing face and bathing, reducing the physical friction and potential irritation of sediment on the skin.
• Cleaning and washing: used for mopping, washing cars, watering plants, etc., to avoid impurities residue causing surface stains or clogging of spray cans.

3. Multi environment adaptive installation

1) Family users

• Urban apartments: Especially suitable for old pipe network communities and high-rise residential buildings, to solve the problem of secondary pollution of tap water.
• Old residential areas: For scenarios where water supply pipelines are aging and prone to secondary pollution (rust, yellow water), pre filters are essential.
• High rise residential buildings: Dealing with pipeline impurity erosion caused by fluctuations in municipal water supply pressure.
• Newly renovated homes: Installed during the water and electricity renovation phase as a basic component of the entire house's water purification system.
• Rural self construction: adapted to complex environments with well water or water sources, efficiently filters high concentration sediment, and protects the stable operation of household water supply systems.
• Strong compatibility: Supports installation of hot and cold water pipelines, compatible with most standard household water pipe interfaces, making it easy to install for both new and old house renovations.

2) Special water quality environment

• Rural self built houses/well water users: In response to high sediment content and suspended solids in water sources, pre filters can significantly improve household water quality and protect water pumps and tanks.
• Near temporary water supply/construction areas: Provide emergency protection in case of temporary turbidity caused by municipal pipeline maintenance or surrounding construction.

3) Non household small-scale application scenarios

• Small commercial venues: coffee shops (protecting coffee machines and boilers), beauty salons (protecting shampoo beds and waterways).
• Agriculture/Horticulture: Greenhouse drip irrigation system, fish tank circulating water pretreatment to prevent nozzle clogging.

This series of faucet water purifiers is suitable for purifying household kitchen tap water terminals, and the incoming water quality should meet the requirements of the "Sanitary Standards for Drinking Water".

Applicable scenarios: Direct connection of municipal water pipelines, water temperature of 5-38 ℃, water pressure of 0.1-0.4MPa.
