Lead can get into drinking water from old lead service lines, lead solder, and some older faucets and fixtures. You cannot see, smell, or taste it. The good news is that many affordable filters are certified to reduce lead. This guide explains which filters work, how to check the certification, and what else you can do to protect your family.

Quick Answer
Yes, many water filters remove lead, but only if they are certified for it. Look for a filter certified to NSF/ANSI 53 for lead reduction, or a reverse-osmosis system certified to NSF/ANSI 58 for lead. Many pitchers, faucet-mounted filters, under-sink filters, and RO systems carry this claim. Always check the exact model, and replace the cartridge on schedule.
Why Lead in Water Matters
The EPA and CDC say there is no known safe level of lead exposure. Children and pregnant people are at the greatest risk, because lead can affect brain development. Lead usually enters water after it leaves the treatment plant, as water sits in lead pipes or older plumbing.
What Is Changing With Lead Rules
In October 2024, the EPA finalized the Lead and Copper Rule Improvements. The rule lowers the lead “action level” that triggers utility response from 15 parts per billion to 10 parts per billion starting in 2027, and requires most water systems to replace lead service lines within 10 years, by about 2037. Industry groups have challenged the replacement timeline in court, and the EPA has been defending the rule. Because replacement will take years, a certified filter is a practical step if your home may have lead pipes.
Does Your Home Have Lead Risk?
- Homes built before 1986 are more likely to have lead pipes, solder, or fixtures
- Ask your water utility whether your address has a lead service line. Utilities have been required to build inventories
- Check the pipe where water enters your home. Lead pipe is dull gray, soft, and shiny when scratched, and a magnet will not stick to it
- Read your utility’s annual water quality report
- The only way to know whether there is lead in your tap water is to test it
Some utilities offer free lead testing. You can also use a certified laboratory or a lead water test kit for screening. See how to test your water before buying a filter.
Filters That Can Reduce Lead
| Filter type | Good for | Look for |
|---|---|---|
| Pitchers | Small households, renters, low cost | NSF/ANSI 53 lead reduction |
| Faucet-mounted filters | Quick installation at the kitchen sink | NSF/ANSI 53 lead reduction |
| Under-sink filters | Larger capacity at one faucet | NSF/ANSI 53 lead reduction |
| Reverse osmosis | Lead plus many other dissolved substances | NSF/ANSI 58 with a lead claim |
| Whole-house filters | Usually not the main lead solution | Lead often comes from plumbing inside the home, after a whole-house filter |

How to Check a Lead Certification
- Find the exact filter or cartridge model number
- Read the performance data sheet and confirm that “lead” is listed under NSF/ANSI 53 or 58
- Look the model up on the certifier’s public listing, such as NSF, IAPMO R&T, or WQA
- A filter certified only to NSF/ANSI 42 is for taste and odor. It is not a lead claim
- Watch for “tested to” language. It is not the same as “certified to”
Use Your Filter the Right Way
- Filter all water used for drinking, cooking, and mixing baby formula
- Use cold water only. Hot water can contain more lead, and most filters are rated for cold water
- Replace cartridges on schedule. An expired filter may stop reducing lead
- Do not boil water to remove lead. Boiling does not remove it and can concentrate it
- If water has been sitting for several hours, run the cold tap for a short time before use, as your utility advises

Other Steps to Lower Lead Exposure
- Clean faucet aerators regularly, since they can trap lead particles
- Ask your utility about lead service line replacement programs in your area
- Replace older faucets and fixtures with lead-free models
- Talk with your doctor about a blood lead test for children if you are concerned
Frequently Asked Questions
Does Brita remove lead?
Brita says its Elite filter reduces 99% of lead. Check the performance data sheet for the exact filter you buy, because not every Brita filter carries the same claims.
Does boiling water remove lead?
No. Boiling does not remove lead and can make it more concentrated as water evaporates.
Does a whole-house filter remove lead?
Not reliably. Lead often comes from pipes and fixtures inside the house, after the whole-house filter. A certified point-of-use filter at the kitchen sink is usually the better choice.
Final Thoughts
If your home may have lead pipes or older plumbing, test your water and use a filter certified to NSF/ANSI 53 or 58 for lead. Filter all drinking and cooking water, use cold water, and replace the cartridge on schedule. For health questions, talk with your doctor or local health department.
