A sink water filtration system is a water purification device designed to improve the quality and safety of the water coming from your kitchen sink. These systems are commonly used to remove impurities, contaminants, and unpleasant tastes or odors from tap water, providing cleaner and better-tasting water for drinking and cooking. Here are the key features and information about sink water filtration systems:

Types of Sink Water Filtration Systems:
- Under-Sink Filtration Systems: These systems are installed beneath your kitchen sink and are connected to the water supply line. They typically consist of multiple filtration stages, including sediment filters, carbon filters, and sometimes reverse osmosis membranes, to effectively remove a wide range of impurities.
- Countertop Filtration Systems: Countertop systems sit on your kitchen countertop and are connected to your sink faucet.They use filters to purify the water as it flows through the system.
- Faucet-Mounted Filters: These are smaller, more portable filtration devices that attach directly to your sink faucet. They are easy to install and provide filtered water on demand when you turn on the tap.
Filtration Methods:
- Carbon Filtration: Most sink water filtration systems use activated carbon filters, which can remove chlorine, sediment, volatile organic compounds (VOCs), and bad tastes and odors from the water.
- Reverse Osmosis (RO): Some under-sink systems incorporate RO technology, which uses a semipermeable membrane to remove a wide range of contaminants, including heavy metals, fluoride, and microorganisms.
- Sediment Filtration: Initial stages in many systems involve sediment filters that capture larger particles like sand and rust.
Contaminant Removal: Sink water filtration systems can effectively remove various impurities, including chlorine, lead, arsenic, bacteria, viruses, pesticides, and more, depending on the type of filtration media and technology used.
Flow Rate and Capacity: The flow rate of these systems varies, and it can affect the speed at which filtered water is delivered. Some systems may also have limited filter capacity, which means you'll need to replace filters periodically.
Maintenance: Regular maintenance is required to ensure the continued effectiveness of the filtration system. This includes replacing filters or cartridges as recommended by the manufacturer.
Installation: Most under-sink filtration systems require professional installation due to their connection to the water supply. Countertop and faucet-mounted filters are typically easier to install yourself.
Cost: The cost of sink water filtration systems can vary widely depending on the type, brand, and complexity of the system. Initial costs include the purchase of the system and installation (if needed), and ongoing costs include filter replacements.
Health Benefits: Using a sink water filtration system can lead to improved water quality, potentially reducing exposure to harmful contaminants, and promoting better health.
Environmental Impact: By filtering tap water at home, you can reduce the consumption of bottled water and minimize plastic waste, contributing to a more eco-friendly lifestyle.

Installing a sink water filtration system can be a practical and cost-effective way to ensure that your household has access to clean and safe drinking water. It's important to choose a system that aligns with your specific water quality concerns and preferences for convenience and maintenance.

User questions & answers

Question:	Cuanto dura cada filtro
Answer:	Dos años cada uno
Question:	Is the faucet brushed nickel finished
Answer:	Hi Javier. Great question, thanks for inquiring with us. Yes, the faucet is made of Stainless steel with brushed nickel finished. Please feel free to contac us any time if you have any more questions. Thanks you. Frizzlife Customer Service Team.
Question:	Just discovered I have pex piping.. How do I proceed
Answer:	PEX is just a supply line. It is an excellent product and would have no affect on using this filter system since all connections are made after the shut off valves under the sink. Now if you choose to put a filter inline and not at the valve, then special PEX brass connectors will be needed along with a PEX tool for installation.
Question:	How often do you need to change the filter
Answer:	Hi dear customer, The filtration capacity for Chlorine is 5000G, and filtration life for LEAD is 1000G, so the filter life can be 1-3 years depend on your daily usage and it can even be 3 years, but we won’t suggest you do the cartridge change that long. As you know the filtration performance is dropping gradually when time goes by, so the longer time you use, the less good water you get. The best time is 1 year or less, the filter cartridge maintenance is much cheaper than the other brands, so it will still save you a lot of money even you change often. Frizzlife suggest no matter what brand of water filtration you will get, do not use that for over 3 years not changing the cartridge, the performance of filtering will be very very low.
