Home and Health: Understanding Lead Contaminants and Filtration Systems


Home is where we seek refuge, comfort, and safety. However, an invisible threat might be lurking within our homes—lead contamination. Lead, a toxic heavy metal, can find its way into our households through various sources such as home piping and industrial runoff, posing a serious risk to our health. In this blog, we'll explore the sources of lead contaminants in homes and discuss the importance of lead filtration systems in ensuring the safety of our water supply.

Understanding Lead Contamination:

  • Lead can enter homes through several avenues, with the most common sources being lead-based paint, plumbing pipes, and certain imported goods. Homes built before 1978 are more likely to have lead-based paint, which can deteriorate over time, leading to dust or chips containing lead. Additionally, lead pipes or plumbing fixtures can contribute to lead leaching into tap water, especially in homes with older plumbing systems. So be sure to check when your home was built and the codes and standards it was built to. 

Health Risks:

  • The health risks associated with lead exposure are severe, particularly for children, pregnant women, and pets. Lead poisoning can lead to developmental delays, learning disabilities, and behavioral issues in children. In adults, lead exposure can result in cardiovascular problems, kidney damage, and reproductive issues. Recognizing the sources of lead and taking preventive measures is crucial for maintaining a healthy living environment. 

Lead Filtration Systems:

Activated Carbon Filters:

  • Activated carbon filters are a popular choice for removing lead from drinking water. These filters work by adsorption, trapping lead particles on the surface of the carbon. The carbon grains are extracted from high grade coconut shells and densely packed inside these filters. While we can’t speak on others, REN Water’s MWH-3 consists of a high-tech lead filter specifically curated to filter out lead alongside VOCs, Chlorine, Tastes, and odors down to 0.5 microns! The human eye can barely see things as small as 30 Microns so imagine 0.5 microns! This is perfect for a system that offers comprehensive health benefits and piece of mind. It's essential to note that the effectiveness of activated carbon filters from other manufacturers may vary, and regular maintenance is crucial to ensure optimal performance. We recommend an annual replacement while others may require more frequent replacement filters.

Whole-House Filtration Systems:

  • All our systems are Whole-house filtration systems, which are installed at the point where water enters the home, ensuring that all water used in the household is filtered. From the kitchen tap to the faucets in your bathrooms everything is filtered. REN Water’s systems may combine various filtration methods, including activated carbon and sediment filters, providing a comprehensive solution for lead and other contaminants.
  • One of the most important things for shopping for these systems is price and maintenance. Money doesn’t grow on trees so choosing which system and how much to spend is crucial. There are many out there who sell useless systems for outrageous prices. Then they require frequent, complicated replacements which also come out near a thousand or two. With REN Water it is simple. No plumber, no useless equipment. It’s a 10 minute filter swap once a year. 

Proper Installation:

  • When installing a lead filtration system, follow manufacturer guidelines and consider professional installation, especially for whole-house systems. Proper installation ensures optimal performance and longevity of the filtration system. While they may not be complicated and DIY follow step by step to ensure a seamless install. 

Do I need a lead filter?

  • If you suspect lead contamination in your home, it's advisable to seek a professional inspection. Periodic testing of your water for lead levels is crucial, especially if you live in an older home or an area with known lead contamination issues. Home testing kits are available and ensure they get tested by an approved, certified testing center for an accurate report on your water. 


Lead contamination in homes poses a significant threat to the health and well-being of occupants. Recognizing the sources of lead and implementing effective filtration systems are crucial steps in safeguarding the quality of your water supply. Should you opt for REN Water’s whole house lead filtration systems or not, the key is to choose a method that suits your specific needs. Our systems are perfect for any home/apartment with water usage up to 15 GPM looking for a whole house filtration system. 

Investing in a reliable lead filtration system is an investment in the health and safety of your household. By staying informed, testing your water regularly, and taking proactive measures, you can create a home environment that is free from the harmful effects of lead contamination.
