Sedimentation is a method of filtration that separates hard and suspended solids from water, making it a crucial step in the purification process.

Sedimentation works by allowing particles to settle at the bottom of a container, leaving cleaner water on top. This ancient technique has been used for centuries and is still effective today.

Activated charcoal treatment is another effective method, where boiled water is poured through a piece of cloth to trap undesired residuals. This simple yet effective method can remove a wide range of impurities from water.

Activated charcoal is particularly good at removing chlorine and other chemicals from water, making it a popular choice for people who want to improve the taste and odor of their drinking water.

Activated carbon filters are another type of water filter that can be effective in removing chlorine and other chemicals from water. They work by passing water through a bed of activated carbon, which absorbs impurities.

Reverse osmosis filters are a type of water filter that use a semi-permeable membrane to remove impurities from water. This type of filter can remove up to 99% of dissolved solids from water.

Ultraviolet (UV) light filters use UV light to kill bacteria and other microorganisms in water. These filters are often used in conjunction with other types of filters to provide a comprehensive solution.

Some countertop filters can be quite affordable, with prices starting at $, making them a great option for those on a budget.

Point of Use filters are a great option for those who want to filter their drinking water. They usually filter water in batches and deliver it to a single tap, such as your kitchen sink.

There are several types of Point of Use filters, including under-sink filters and those that attach to your faucet. Consider this option if you only need to filter the water you drink and cook with.

Some Point of Use filters use more than one filtration method, making them very effective at removing contaminants. Examples include multi-barrier systems and filters that combine granular-activated carbon with other methods.

If your tap water does not contain harmful germs or chemicals, you may not need a Point of Use filter. But if you're concerned about safety or taste, a Point of Use filter can be a good choice.

Here are some common types of Point of Use filters:

For households with multiple people, a pitcher or dispenser with a large water capacity is a must. The Brita Ultramax Dispenser holds enough water for a large household's daily needs.

Its spill-resistant spigot is a thoughtful design feature that makes it easy for children to use.

If you're short on counter space, consider a pitcher or dispenser with a compact design.

Sedimentation is a simple yet effective way to remove suspended solids from water. It's often used in conjunction with other methods to achieve better results.

Activated charcoal treatment is another ancient method that's still widely used today. It involves pouring boiled water through a cloth to trap unwanted residuals.

Activated charcoal is particularly effective at removing impurities and improving the taste and odor of water. I've used activated charcoal filters in the past and can attest to their effectiveness.

Filters can remove particles much smaller than the holes through which water passes, including nitrates and germs like Cryptosporidium. This is because filters use various processes like sieving, adsorption, and ion exchanges.

Some filters can remove bacteria like Salmonella and E. coli from water. These filters typically have an absolute pore size of 0.3 micron or smaller, or use ultrafiltration, nanofiltration, or reverse osmosis.

Here are some common filtration methods:

Portable water filters are small, portable, and lightweight, usually weighing 1–2 lb (0.45–0.91 kg) or less. They're perfect for hikers, aid organizations, and the military.

Some portable filters work with a mechanical hand pump, while others use a siphon drip system. Dirty water is pumped through a screen-filtered flexible silicon tube, and clean water ends up in a container.

Portable filters are designed to remove bacteria, protozoa, and microbial cysts that can cause disease. They may have fine meshes that need to be replaced or cleaned, and ceramic filters require their outside to be abraded when clogged.

Whole-home filters, also called point-of-entry filters, filter water as it comes into your home.

Water filters can improve the taste of water, the safety of water, or both. This is especially important if you have concerns about the quality of your tap water.

To choose the right filter, test your water and identify the specific contaminants you want to remove. This will help you select a filter that targets those particular issues.

If your tap water is already safe and free of harmful germs or chemicals, you may not need a filter.

Regular maintenance is crucial to keep your filter working properly and prevent germs from growing in it. You'll need to change filters according to the manufacturer's recommendations.

Wear gloves while changing filters and wash your hands afterward to avoid getting sick.

Always check the label of your water filter, especially if you're looking to improve the safety of your water. This is because different filters are designed to remove different types of germs and chemicals.

Some filters, like those that use activated carbon, are mainly designed to improve the taste and smell of water, rather than its safety. They may be certified to NSF standard 42, which indicates their ability to remove certain contaminants.

Microfiltration, ultrafiltration, and nanofiltration filters remove different types of germs depending on the pore size of the specific product. This means you should check the label to see what types of germs each filter is designed to remove.

Take a look at this: Irrigation Check Valves

Reverse osmosis filters, on the other hand, are designed to remove germs and some types of chemicals, making them a good choice if you're concerned about the safety of your water.

Here's a quick rundown of what to look for on the label:

To ensure we recommend only trustworthy filters, we follow a rigorous process. We insist that our picks meet the gold standard: ANSI/NSF certification.

The American National Standards Institute (ANSI) and NSF are private, nonprofit organizations that establish strict quality standards and testing protocols for thousands of products, including water filters. They work closely with the EPA, manufacturers, and experts to ensure filters meet the highest standards.

We test filters to their limits, using "challenge" samples that are far more polluted than most tap water. This ensures filters can remove contaminants even when faced with extreme conditions.

We accept filters that have been "tested to ANSI/NSF standards" if certain conditions are met. This includes testing by an independent laboratory, not the filter manufacturer, and the laboratory itself being accredited by ANSI or another national or nongovernmental equivalent.

We further narrowed our scope to filters with, at a minimum, certification or the equivalent under the two main ANSI/NSF standards, Standard 42 and Standard 53. Standard 42 covers chlorine and other "aesthetic" contaminants, while Standard 53 covers heavy metals like lead and organic compounds like pesticides.

Here are the key factors we consider when evaluating filters:

Removing contaminants from water is a crucial aspect of using a water filter. Filters can remove both good and bad substances from your water, including beneficial chemicals like chlorine and fluoride.

Some filters, like reverse osmosis filters, can remove a wide range of chemicals, including lead, copper, and arsenic. These filters may also reduce fluoride, radium, and other chemicals.

To ensure a filter removes the contaminants you're concerned about, check the filter's label for certification from reputable third-party testing organizations like NSF, WQA, or IAPMO. Look for the code NSF/ANSI 53 (or NSF/ANSI 58 for reverse osmosis systems) to indicate the filter is certified to remove PFAS.

Here are some common contaminants and the types of filters that can remove them:

Filters remove both good and bad substances from your water, including germs that can make you sick.

To ensure your filter is effective, check the pore size to see if it's small enough to remove the type of germ you're concerned about. For example, parasites and amebas are larger than bacteria, which are larger than viruses.

Parasites like Giardia and Cryptosporidium can make you sick if you swallow them, and the ameba Naegleria fowleri can make you sick if it goes up your nose while rinsing your sinuses.

To remove parasites and amebas, look for filters that meet the following criteria:

Viruses, such as norovirus or Hepatitis A, can also be removed with the right filter. Nanofiltration and reverse osmosis are effective methods for removing viruses from water.

Reverse osmosis filters can remove a wide range of chemicals from water, including lead, copper, and arsenic.

Some filters may also reduce fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous.

If your tap water is already free from harmful germs and chemicals, you may not need a filter at all.

To ensure a filter can remove specific chemicals, check the filter's label for certification by a reputable third-party testing organization.

Certified products are independently tested and found to comply with an accepted standard specific to that contaminant.

Reputable third-party testing organizations include NSF, WQA, IAPMO, UL Solutions, CSA Group, and Intertek (ETL).

For a filter that can remove PFAS, look for one with the code NSF/ANSI 53 or NSF/ANSI 58 for reverse osmosis systems.

Some filters may make unsubstantiated claims about removing chemicals, but it's essential to verify their certification before making a purchase.

PFAS removal is a crucial aspect of water filtration. You can find out if your water has PFAS by checking your Consumer Confidence Report (CCR) from your water supplier.

The Environmental Protection Agency (EPA) established limits for PFAS in drinking water in 2024, but the agency rescinded and reconsidered the limits on four of the compounds in 2025. This means consumers need to rely on individual state action and their own awareness of PFAS levels in their water.

Some states, like Maine, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Washington, and Wisconsin, have established standards for the level of PFAS in drinking water.

To remove PFAS from your drinking water, you can use a home water filter that's certified to remove PFAS. Look for filters with the code NSF/ANSI 53 (or NSF/ANSI 58 for reverse osmosis systems), followed by the manufacturer's claim that the product can remove PFAS.

Certified products will also bear a seal from the testing organization that identifies which contaminants they reduce. Reputable third-party testing organizations include the National Sanitation Foundation (NSF), Water Quality Association (WQA), and International Association of Plumbing & Mechanical Officials (IAPMO).

If you're looking for a water filter that's effective at removing disinfection byproducts, I'd recommend checking out the PUR Plus or Amazon Basics options.

They're nearly 100 percent effective at removing these byproducts, which is a big plus in my book.

These two options also offer a lower price point compared to other water filters on the market, making them a great choice for those on a budget.

If you're in the market for a water filter pitcher, you've got several options to consider. The Pur Plus is nearly 100 percent effective at removing disinfection byproducts at a lower price.

The Amazon Basics 10-Cup Water Filter and Pitcher is a cheaper alternative to the top-pick Amazon-exclusive Brita Everyday, but it has a one-piece lid that you have to remove and replace every time you need to refill the pitcher.

While the Pur Plus has a design that's hard to beat, its filters' shortcomings mean it's no longer a top recommendation. The Amazon Basics 10-Cup Water Filter and Pitcher is a good option if you're willing to deal with a slightly less convenient lid.

Ultimately, the choice between the Pur Plus and Amazon Basics comes down to your priorities and budget.

In 2016, we conducted our own tests on multiple filters to compare results against ANSI/NSF certifications and manufacturer claims.

We measured each filter's removal of chlorine in a lab, and for our top two picks, we contracted an independent test for lead removal using a more contaminated solution than the NSF certification protocol requires.

Our main takeaway from testing is that ANSI/NSF certification or the equivalent is a reliable measure of a filter's performance, thanks to the rigor of the certification standards.

Since then, we've relied on ANSI/NSF certifications to determine a filter's capabilities, as they provide a consistent and trustworthy measure of a filter's effectiveness.

We've focused our subsequent tests on real-world usability, looking at practical features and drawbacks that become apparent only after using these products long-term.

The Elite filter's certifications apply only when used in a pitcher or dispenser with a performance indication device (PID) that measures the volume of water passed through the filter, but we don't think this matters due to the rigorous testing standards.

Brita's Ultramax Dispenser is a great option for large households, holding enough water for daily needs and featuring a spill-resistant spigot that's easy for kids to use. It's a reliable choice for families with young children.

Brita's filters can be prone to clogging, especially with sediment. The LifeStraw Home Dispenser, on the other hand, has a filter that's far more resistant to clogging than Brita's, making it a great alternative for those who have experienced clogging issues.

The LifeStraw filter is certified to remove bacteria and parasites, providing protection against some waterborne illnesses. However, it's still recommended to use bottled water during a boil-water notice.
