Water is life. Every living creature on earth needs water to survive. Yet, the water resources have become limited, the access to clean water source particularly. To solve this problem, water filters and related water filtration products are being developed to fulfill the market needs.
What Is A Water Filter System
A water filter system is like an appliance using water filtration technology to remove impurities from the water. The commonly used filtration technologies include physical filtration barrier, chemical process, and biological process.
Today, most home-use water filter systems are using the physical filtration method. It involves a progressive structure based on the principle of blocking and filtering, which uses the pressure difference to filter.
Similar to a sieve that sifts sand, sands that are larger than the sieve will be retained and those smaller than the sieve screen will pass through. The quality of the water highly depends on the size of the filtration media, also known as filtration accuracy.
The filtration accuracy determines what would be filtered out. In layman's terms, various filter materials are used to intercept harmful components in the water, and only get the clean water to pass through.
Harmful Impurities Found in Water
The water contaminants that are commonly found in water include:
- Sands
- Chlorine
- Fluoride
- PFAS
- Viruses
- Microorganism
- Nitrates
- Phosphorus and phosphoric acid
- Lead
- Arsenic
- Nickel
- Chromium
Types of Water Filter Systems
As we have mentioned above, the principle of the water filter system is to filter out impurities in the water through layers of filtration media. The water filter systems you can find on the market vary in shapes and designs, but the internal filter membrane can be categorized into the following types:
- Quartz Sand layer
- Stainless steel filter screen
- PPF cotton
- Ordinary activated carbon
- Coconut shell activated carbon
- Ceramic filter element
- Microfiltration
- Ultrafiltration
- Nanofiltration
- RO membrane
RO membrane filtration is currently the best terminal filtration method, and it is also usually the last filtration stage of a water filter system.
The following section will introduce to you some best water filter systems you can find on the market.
Reverse Osmosis Water Filter
A well-designed RO system should include at least one granular activated carbon filter element, one reverse osmosis filter element, and one post-activated carbon filter. The Waterdrop G3 P800 reverse osmosis system fulfills those basic requirements and brings water purification to the next level.
Space-saving
The advanced tankless design and innovative composite filter allow the system to achieve supreme filtration performance with minimum space.
Finest filtration performance
The multistage filtration media not only can remove impurities such as sand, rust, bacteria, suspended solids, etc., but also remove metal ions and radioactive substances such as calcium and magnesium in the water, and completely purify and reduce the TDS (Total dissolved solids) in water. The UV sterilization layer provides 360-degree protection against any contamination.
Efficiency
Featuring a breakthrough water-saving technology, the G3 P800 lowers the drain ratio to 3:1, meaning you can get 3 cups of pure water with only one cup of wastewater. This excellent drain ratio can save 12 times more water compared to the traditional RO systems and reduce the water bill as well.
Smart design
The system’s front panel design allows you to monitor real-time water TDS values and filter life status with a glance. The 800 GPD large capacity and fast water flow make the system an ideal choice to satisfy the water needs of large households or small business offices.
Whole House Water Filter
The Waterdrop whole house water filter system is a pre-filter designed to be the first defense line of your home.
Versatility
Having a whole house filter installed can protect your home appliances from clogging and scale build-up, which eventually prolongs the service life. You can trust the clean filtered water for washing, cooking, taking shower, and doing laundry.
Unlike other water systems that are usually installed inside the kitchen settings, the whole house water filter systems can be installed anywhere with your home water lines.
Effective removal
The system adopts a 2-stage filtration process that can effectively remove large particles like dirt and sands while improving the water taste by removing chlorine and bad odor.
Long lifespan
As a pre-filter, the short lifespan has always been a headache problem for many house owners as the filters can easily be clogged by the large particles and sediments in the water. The Waterdrop whole house water filter uses advanced filter design to solve the problem and extends the lifespan to up to 6 months.
Sturdy design
The Waterdrop whole house water filter is built out of high-quality materials that are able to withstand extreme outside conditions. The special dual-sealing design prevents water from leaking and the pressure release design saves you much effort when replacing the filters.
Under Sink Water Filter
If you are looking for an efficient undersink water filter with zero wastewater, then the Waterdrop ultrafiltration undersink water filter would be a perfect choice.
Smart indicating system
Similar to the Waterdrop RO line, this ultrafiltration system comes in a compact tankless design. The indicating system as displayed on the front panel allows you to check the filter life status in real-time.
Excellent filtration performance
With a fine filtration accuracy of 0.01-micron, the ultrafiltration membrane can reduce 99.99% chlorine. The system can also effectively remove lead, chloramine, fluoride, heavy metals, VOCs, and other common water contaminants.
Extended filter life
The advanced filter design enables the system to run up to 24 months without the need to concern about the UF filter replacement. The long lifespan not only reduces the frequency of filter replacements but also saves maintenance costs and efforts.
Countertop Water Filter - Waterdrop N1
For people who are concerned about the waterline connection and hole drilling, the countertop reverse osmosis system might be the right solution. As the leading brand in the water purification industry, Waterdrop just released the N1 countertop reverse osmosis system.
Convenience
The N1 system looks like a water dispenser that requires no installation and drilling work. The system carries all the benefits of an RO system with an additional UV light sterilizer to provide extra protection for the filtered water.
Cost-effective
The advanced filtration technology of this RO system achieves an impressive 3:1 drain ratio, meaning you only discharge one cup of wastewater for every three cups of clean water. Besides the reduction in water consumption, the system automatically goes on standby mode or sleep mode when not in use to minimize energy usage.
If you want the best water quality but are worried about the installation hassle, you can trust the N1 system to deliver you clean water nearly anywhere with an electrical socket.
Gravity-Fed Water Filter
Great purification capability
This gravity-fed water filter from Waterdrop can filter out suspended solids, bacteria, rust, algae, microorganisms, and other impurities in water through the adsorption of activated carbon. It can also filter out almost 99% of the residual chlorine in the tap water, bringing you filtered water that is healthier to drink.
High quality
This water filter system is built out of 304 food-grade stainless-steel material, meaning the housing of the system is corrosion-proof. The metallic water level spigot prevents water leakage and ensures inside water safety.
Large capacity and long lifespan
The Waterdrop King Tank stainless steel gravity water filter comes in a 2.25-gallon large capacity, which is enough to keep a medium-sized family stay hydrated the whole day. The advanced activated carbon filters are capable of filtering up to 6,000 gallons of water.
Accessibility
The complete accessory kit ensures you need no additional tools for installation. Unlike other water filters that need to run under electricity, the King Tank is gravity-based and can be used anywhere even during extreme conditions. You can easily get safe drinking water with the Waterdrop King Tank water filter system.
