Lead is a heavy metal that leaches into drinking water through corroded pipes and fixtures in homes, making it one of the most prevalent contaminants in tap water.
Lead contamination is an urgent problem that must be addressed. It can affect people of all ages and has been linked to health problems such as cognitive deficits and memory loss.
Reverse osmosis removes lead and chlorine from tap water by forcing it through a semi-permeable membrane.
Removing lead and chlorine from water can reduce health risks. Reverse osmosis also removes water odors and tastes.
Selecting the right system ensures your family has clean, healthy water. Check your budget, space, and needs.
Under-sink reverse osmosis is best for most applications. Countertop models use little plumbing and dispense filtered water from the faucet. If you have a large family, you may want a larger storage tank to store more filtered water.
Carbon filters remove chlorine, lead, and other pollutants from drinking water. Carbon activated by steam or high temperatures without oxygen creates millions of pores for greater surface area and adsorption capacity in these filters.
Coconut shells and corn husks can boost the effectiveness of activated carbon from coal, wood, or peat. Steam or chemicals enhance their adsorption after preparation.
Most CTO-removing activated carbon filters (chlorine, taste, and odor). Through mechanical filtration, submicron carbon block filters can also remove coliform, cysts, lead, and iron. Material safety requires third-party testing and certification of carbon filters.
KDF works well in filters. It boosts contaminant removal in activated carbon/blocks carbon filters and under-sink or faucet filters.
KDF transfers electrons between impurities to create new elements, which are harmless. These water-soluble compounds are flushed away during backwashing.
KDF removes chlorine, lead, and soluble heavy metals like iron, copper, nickel, zinc, chromium, and hydrogen sulfide.
Showerhead filters and well water treatment use KDF process media. Unfortunately, backwashing is needed to remove contaminants (at least every 9–12 months). Unfortunately, high flow rates and incoming water pressure are rare. Luckily, some manufacturers combine KDF process media with other filtration technologies to extend its lifespan and reduce maintenance.
Reverse osmosis systems remove more lead than water filters. They remove chlorine, odor, and limescale but not lead or pesticides.
Water filters remove particles before they enter your home, reducing their concentration and risk. This includes chlorine, small particulates, bacteria, and microbial cysts from municipal water sources.
Ion exchange water filters are common in homes. A resin bed with cation and anion beads is used (anions).
