Industrial pollution has led to increasingly serious pollution of heavy metals such as mercury, cadmium, chromium, lead, manganese, zinc, and arsenic.Water filters have become one of the effective ways to solve water pollution, and people are most concerned that heavy metals in water that can cause cancer. So, what kind of water filter can effectively remove heavy metals?
Water filter that removes heavy metals
At present, there are several water purification technologies suitable for the removal of heavy metals: one is activated carbon adsorption, the other is chemical reaction removal by KDF filter element, and the third is RO reverse osmosis membrane filtration.
A pure ultrafiltration membrane cannot filter out heavy metals, which is determined by the filtration pore size of the membrane, because the filtration pore size of the ultrafiltration membrane is generally 0.01 microns, and the diameter of heavy metals such as lead ions is 0.28 nanometers. RO reverse osmosis water filter is currently the most ideal water purification product for heavy metal purification, and belongs to the middle and high-end water filters. It can completely pass through the pore size of the ultrafiltration membrane. The filtration pore size of the RO reverse osmosis membrane is 0.0001 microns, that is, 0.1 nanometers, so it can filter out heavy metal ions.
The chemical reaction of KDF filter element can remove heavy metals. The adsorption of activated carbon can remove some heavy metals in water. The removal rate of heavy metals has a great relationship with the quality of activated carbon. Activated carbon includes coal charcoal, nut shell activated carbon, bamboo charcoal, etc. Shell activated carbon, the filtration principle of the water filter is the principle of physical screening. The smaller the aperture, the higher the filtration precision, and the safer the water quality. Therefore, only if the filtration accuracy is less than the diameter of the above heavy metal ions and viruses can ensure that there is no heavy metal pollution and virus hazards in the water.
best water filter for heavy metals
Since there are so many heavy metals in the water that cannot be removed by heating, external equipment is needed.The heavy metals water filter was born specifically to filter heavy metals.Here are some of the water filters that best for heavy metals.
1.HideAway T1 five-Stage Reverse Osmosis Water Filter
This heavy metals water filter is equiped With five stages reverse osmosis water filter process, the filtration system can remove up to 99% of harmful including heavy metals in the water,
2.HideAway Ultimate 6-Stage Reverse Osmosis Under Sink Water Filter
With 6 stages reverse osmosis water filter process, the filtration system can remove up to 99% of harmful contaminants such as heavy metals in the water,
3.SpaceSaver Tankless Reverse Osmosis System
SimPure Q6 tankless reverse osmosis system 4-stage with a filtration accuracy of 0.0001 μm. It removes 99.99% of 1000+ harmful contaminants from your tap water, including lead, chlorine, fluoride, chloramine, odors, heavy metals, chemicals, TDS, limescale, etc.
4.SimPure Water Filter Straw
The water filter straw creatively designed with 4-in-1 filtration: Pre-filter removes large and solid sediments in water; PP cotton fiber filters out small particles like sand; Coconut shell activated carbon removes odor, heavy metals, etc
5.Simpure Water Filtering Pitcher
This AS & ABS material water filtering pitcher can reduces chlorine taste and odor, heavy metals and other impurities found in tap water. It reduces TDS value by up to 15% and chlorine up to 97%.
Boiling water cannot be effectively remove heavy metals,which may cause cancer. Therefore, it is necessary to use a water filter to effectively filter out the heavy metals.
