The water filter was invented by the Germans, but the most powerful is the American brand, and the American brand is the first to be Clear2O. Clear2O is a well-known water purification brand in the North American market, ranking among the top three in the North American market share, with outstanding strength, but it is not well-known in the domestic market. Its products include water filters, whole-house water purifiers, and filtering sports bottles, the most famous of which is the water filter bottle.
 
Clear2O's water filter jug is represented by the CWS100, which ranked first in the U.S. Consumer Reports' water filter jug evaluation and received a "Best Buy" rating.
 
The traditional water filter pot uses the gravity of the water itself to filter, and the water flows out slowly through the filter element in the pot, which is long and inefficient. Clear2O's original solid carbon block pressurized filtration technology greatly shortens the filtration time, and it only takes a few seconds to filter out a pot of water, which solves the problem of long waiting.
 
The filtration effect of the water filter pot is determined by the filter element, the solid carbon block technology is to replace the small particles of activated carbon in the filter element with a whole piece of carbon, which is connected to the faucet through an adapter, and the filtration process is accelerated with the help of the pressure of the water flow when the water is filled, when the water is forced to pass through the carbon block, the carbon will capture and adsorb pollutants, and solid carbon can filter more pollutants than granular carbon. This technology is used on the CWS100.
 
In addition to its extremely fast filtration speed, Clear2O also has excellent filtration performance, removing 53 contaminants, far more than Brita's 21, and removing lead and organic compounds more efficiently than Brita.
 
CWS100 comes with an adapter, screw it into the locked position and close the lid to use, there is a tutorial video on the official website, you can watch it for reference when you first install and use it. The disadvantages are that the included adapter is only suitable for standard faucets, which is not compatible with spray faucets, and the included tube is shorter, and there are long tubes on the market that can be replaced. The CWS100 filter can filter 50 gallons (about 190L) of water, which is nearly 140 liters more than Brita.
 
Clear2O's other two products, the GRP200 and the CAP350BL, are gravity water filter jugs. The GRP200 water filter jug adopts a lid-free design, which can be easily filled without removing the lid, and the water outlet can be automatically opened when pouring water, which is easy to operate and avoids secondary pollution. The filter element is a calcium ion filter element, which grafts nano alumina fibers to microglass fibers to form a filter medium with a strong positive charge, and removes pollutants of more than 1 micron through electroadsorption, which is better than mechanical filtration. The GRP200 filters up to 1.42 liters of water at a time, making it portable, with a 60 gallon (227 liter) filter life.
 
CAP350BL advertise alkaline water filters as adding calcium, magnesium, and other beneficial minerals to strengthen water and increase pH. But in fact, scientific research has proved that alkaline water has no obvious health benefits for the human body, and is just a marketing concept. However, this does not prevent CAP350BL from being an excellent water filter pot, and its filter element uses 5-stage filtration, such as micro-grid, activated carbon, tourmaline mineral layer, porous stone, and non-woven membrane filter media, which can effectively remove particulate matter, scale, residual chlorine, organic matter, lead and mercury, and its performance ranks in the upstream of similar products, which is comparable to the Brita Marella series. Cartridge life is 80 gallons (300 liters).
 
Clear2O's water filter jug is made of food-grade material and does not contain BPA, so you can use it with confidence. All three water filters cost around $30 on Amazon in the United States, and the filter cartridge is about $10, which is relatively low in cost per year, and all are equipped with a filter life indicator to tell the user when to replace the filter. It should be noted that the filter cartridges of the three products cannot be used universally, and consumers should pay special attention when purchasing.
 
Unfortunately, although Clear2O's products have excellent performance, they have not yet entered the Chinese market and can only be purchased through purchasing agents or overseas shopping.
