The Wirecutter’s Guide to Choosing the Best Water Filter
Finding the right water filter can feel tricky. You want clean, great-tasting water without spending too much time or money. Wirecutter often tests and recommends the best gear. This guide helps you pick a filter that fits your needs, just like their expert reviews.
Key Features to Look For
Good water filters do more than just make water taste better. They remove harmful stuff too. Think about what you need the filter to do.
Contaminant Removal
- Lead: This is super important, especially in older homes. Make sure the filter explicitly says it reduces lead.
- Chlorine: This chemical keeps city water safe, but it tastes and smells bad. Most good filters remove chlorine well.
- Microplastics and Cysts: These tiny particles can be in your water. Look for filters certified to block them.
Flow Rate and Capacity
How fast does the water come out? If you need a lot of water quickly, a slow pitcher filter might frustrate you. High-capacity filters mean you change the cartridge less often, which saves time.
Certifications
Look for seals from organizations like NSF International. These seals prove the filter works as advertised. Certification Standard 42 deals with taste and odor. Standard 53 deals with health-related contaminants like lead.
Important Materials in Water Filters
The material inside the filter does the hard work. The type of material affects what the filter can remove.
Activated Carbon
This is the most common material. Carbon works like a sponge. It traps chlorine and bad tastes. Granular Activated Carbon (GAC) and Carbon Block filters are the two main types. Carbon Block filters are usually denser and remove smaller particles better.
Ion Exchange Resins
These materials swap out bad minerals for harmless ones. They are often used to reduce hardness or remove heavy metals like lead.
Factors That Improve or Reduce Quality
Not all filters are created equal. Some design choices make a big difference in performance and ease of use.
Filter Lifespan (Quality Booster)
A filter that lasts longer means less waste and fewer trips to the store. A pitcher filter might last two months. A whole-house system lasts years. Check the stated lifespan in gallons.
Ease of Installation and Use (User Experience Factor)
If you buy a faucet filter, can you install it without tools? Can you easily see when the cartridge needs changing? Simple designs usually lead to happier users. Complicated setups often get ignored.
Filter Clogging (Quality Reducer)
If you start with very cloudy or silty water (like well water), your filter might clog fast. This slows down the flow rate dramatically. Pre-filters can help prevent this clogging in heavy-use situations.
User Experience and Use Cases
Where and how you plan to use the filter changes what you should buy.
Pitchers and Dispensers
These are great for renters or small households. You fill them up and keep them in the fridge. They are very easy to use. The downside is they take up fridge space and filter slowly.
Faucet Mounts
These attach directly to your kitchen sink faucet. They offer filtered water on demand. They are convenient but might not fit all faucet styles. They are a good middle ground for families.
Under-Sink Systems (Reverse Osmosis or Multi-Stage)
These offer the highest quality filtration and large volumes of water. They require installation under your sink, sometimes taking up cabinet space. These are best for people serious about water quality who plan to stay in their home for a while.
Water Filter Wirecutter FAQs
Q: What is the main difference between a pitcher filter and a faucet filter?
A: Pitcher filters hold water in a container you keep in the fridge. Faucet filters attach to your tap and filter water as you pour it out. Pitchers need refilling; faucet filters are instant.
Q: How often should I change the filter cartridge?
A: This changes depending on the brand and how much water you use. Most standard pitcher filters last about 40 gallons, often 2 to 3 months. Always check the manufacturer’s instructions.
Q: Are expensive filters always better?
A: Not always. An expensive filter is only better if it removes contaminants you actually need removed. A $30 filter certified for lead removal might be better for you than a $150 filter that only removes chlorine.
Q: Can a water filter remove bacteria?
A: Most standard carbon filters do not remove bacteria or viruses. If you use well water or are worried about pathogens, you need a filter specifically rated for microbial removal, like some UV or specialized reverse osmosis systems.
Q: What does “NSF Certified” really mean?
A: It means an independent group tested the filter and confirmed it removes what the label says it removes. It is proof the product works correctly.
Q: Will a filter change the pH of my water?
A: Some filters, especially Reverse Osmosis (RO) systems, can slightly lower the pH, making the water a bit more acidic. Other filters might slightly raise it. It usually isn’t a big health concern for most people.
Q: Do I need a filter if I already drink city tap water?
A: City water is safe, but it often contains chlorine and sometimes trace amounts of lead or other chemicals that travel through old pipes. A filter improves taste and removes these traces.
Q: What is the biggest quality reducer when using a filter?
A: Not changing the filter on time. When the filter media gets full, it stops working well. Sometimes, old, dirty filters can even release trapped contaminants back into the water.
Q: Are filter pitchers good for travel?
A: Some companies make smaller, travel-sized pitchers or personal water bottles with built-in filters. These are great for camping or hotel use where you are unsure of the water source.
Q: Does filtration remove healthy minerals from the water?
A: Yes, some systems like Reverse Osmosis remove almost everything, including healthy minerals like calcium and magnesium. Standard carbon filters usually leave most of these beneficial minerals in the water.
