- Test or check your water first. If it has no harmful germs or chemicals, you may not need a filter (CDC).
- Most pitcher filters are not designed to remove germs. They use carbon to improve taste or reduce metals like lead (CDC).
- For lead, look for a filter certified to NSF/ANSI 53 with a lead claim, and ideally NSF/ANSI 42 too (EPA).
- Popular pitchers and filters are listed below with Amazon links. Read each performance data sheet.
A water filter pitcher is one of the cheapest ways to change how your tap water tastes, and in some cases to reduce certain contaminants such as lead. But filters differ a lot, and many do not do what people assume. This guide summarizes what the CDC, the EPA and NSF say about choosing a home water filter, and lists popular, widely reviewed pitchers and filters on Amazon. If you have a weakened immune system or a private well, read the notes carefully and talk to your health care provider.
1. Do You Need a Filter at All?
The CDC says water filters can improve the taste of water, the safety of water, or both. It advises you to test your water and choose a filter that removes the harmful germs or chemicals you are concerned about. If your tap water does not contain harmful germs or chemicals, you may not need a filter. The CDC also notes that some filters can remove beneficial chemicals, like chlorine, which kills germs in water, or fluoride, which prevents cavities.
NSF suggests starting by getting a copy of your water quality report (also called a consumer confidence report) from your local water utility. If you have a private well, consider having your water independently tested.
2. Most Pitcher Filters Do Not Remove Germs
The CDC says most home water filters, like pitcher or fridge filters, are not designed to remove germs from your water. They typically use a carbon filter to make water taste better or remove heavy metals like lead. If you have a weakened immune system, the CDC says to talk to your health care provider and a water disinfection specialist about whether to get a water treatment system, to look for one that will remove Cryptosporidium, and to avoid changing water filters yourself, because changing a filter could expose you to the germs or chemicals caught in it.
3. Look for Certification, and for the Specific Claim
The CDC says one way to figure out what a water filter removes is to look for an NSF certification on the label. The EPA says there is no mandatory federal requirement for third-party certification of point-of-use filters, but you can increase your confidence by buying a filter tested by an accredited third-party certification body. For lead, the EPA’s consumer tool says to look for a filter evaluated for lead reduction to 5 parts per billion (ppb) or less and particulate reduction (Class I), against both NSF/ANSI Standards 53 and 42.
- NSF/ANSI 42 covers aesthetic effects such as chlorine taste and odor and particulates.
- NSF/ANSI 53 covers health-related reductions such as lead, if the product claims it.
- NSF says to check the packaging for both the standard name (such as NSF/ANSI 53) and a claim for specific contaminant reduction, such as lead.
4. Popular Pitchers and Dispensers on Amazon
These are widely reviewed examples. Whether a given pitcher or filter is certified for lead depends on the model and the filter inside it, so read the packaging and the performance data sheet before you rely on it. The listings do not guarantee any particular certification.

5. Faucet-Mount and Other Options
NSF notes that point-of-use systems treat the water where you drink or use it, and include water pitchers, faucet filters and reverse osmosis systems. A faucet-mount filter can be a good option if you do not want to refill a pitcher, but check the certification too.
6. Keep Your Filter Working
- Replace the filter when required (NSF). A filter past its life may not work as claimed.
- Wash the pitcher regularly, following the maker’s instructions.
- If you have a weakened immune system, ask someone else to change the filter or ask your provider first (CDC).
- Keep your water quality report and the filter performance data sheet together.
7. Frequently Asked Questions
Does a pitcher filter make water germ-free?
No. The CDC says most pitcher and fridge filters are not designed to remove germs.
How do I know a filter reduces lead?
The EPA says to look for a filter certified by an accredited third party against NSF/ANSI Standard 53 with a claim of lead reduction, ideally also tested against NSF/ANSI 42. Check the packaging and performance data sheet.
Do I need a filter if my water is safe?
The CDC says if your tap water does not contain harmful germs or chemicals, you may not need a filter.
What if I have a private well?
NSF suggests having your water independently tested. Talk to a water treatment professional and your health department.
