Filters for Lead Removal Must be Certified to Meet NSF 53

Filters for Lead Removal Must be Certified to Meet NSF 53

Various types of water treatment devices are certified for household use. These devices can remove a broad range of contaminants from water — including lead — and minimize taste and odor issues. You should choose the type of filter that best fits your needs.

If you have a lead source or do not know if you have a lead source, DC Water recommends that you filter your water before drinking and cooking until all sources of lead have been removed. This includes water used for making infant formula, beverages, and ice.

Certified Filters

  • Any type of water treatment device that you choose should meet National Sanitation Foundation (NSF) standards.
  • For lead removal, filters must be certified to meet NSF Standard 53. The filter package should specifically list the device as certified for removing the contaminant "lead."
  • View the NSF Contaminant Guide.

Types of Water Filters

  • Various styles of devices are available, including point-of-entry (POE) and point-of-use (POU).
  • DC Water recommends point-of-use filters, such as faucet mounts and pitcher-style, and filters that have protection against microbial growth.
  • Visit the NSF Home Water Treatment Devices Guide.

Water Filter Maintenance

  • It is important to routinely replace filter cartridges according to the manufacturer's instructions. Over time, a filter can accumulate metals and bacteria.
  • Water filters and cartridges can vary in their longevity (length of use) and replacement costs.
