Not every water filter removes lead, and a general “certified” label doesn’t mean it does. Tell us what kind of filter fits your home, and we’ll show models whose lead reduction we checked on NSF’s own certification listings, with capacity, replacement schedule and where to buy.
In short: look for certification to NSF/ANSI 53 for lead reduction (or NSF/ANSI 58 for reverse osmosis systems), confirmed on the certifier’s listing for that exact model. Then use the filter as directed and replace the cartridge on time; a used-up cartridge stops reducing lead.
How we choose the filters
We include a filter only when NSF’s public listing for that model shows lead reduction under NSF/ANSI 53 or 58. Each card links to the listing so you can check it yourself before you buy. Other certifiers (such as WQA and IAPMO) also certify filters for lead; we haven’t added models certified only by them yet, because we couldn’t check their listings the same way. Prices change often: each card shows when we saw the price.
| Type | Good for | Keep in mind |
|---|---|---|
| Pitcher | Renters, small households, no installation | Few pitchers are NSF-listed for lead; slow to fill |
| Faucet-mount | Filtered water straight from the tap, no plumbing | Doesn’t fit every faucet; filters only that tap |
| Refrigerator | Homes with a fridge water dispenser | Only the water and ice from the fridge |
| Under-sink | A dedicated filtered tap, larger capacity | Needs plumbing work |
| Reverse osmosis | Most thorough treatment at one tap | Needs plumbing; wastes some water; slower |
A filter is not the whole fix
A certified filter reduces lead in the water that passes through it, at that tap. Use filtered or bottled water for drinking, cooking and baby formula, find out whether your service line is lead, and test your tap water with a certified lab.
