Buyer’s Guide – How to Select the Best Water Filter
A water filter is your first line of defense against the harmful contaminants in tap water. But there are no fewer than a dozen types of water filters using different filtration methods that only target specific substances. No one model does it all, so we’ll help you identify the best water filters for your unique filtration needs.
Why You Should Trust Us?
We’re not rocket scientists, but we understand the importance of clean water and what it means to you and your family. Our team has decades of experience in the filtration industry.
Our buying guides and product reviews were written exclusively for you — the average consumer who just needs a hand selecting a quality water filter. Your trust is priceless, and we work hard to earn it.
How We Evaluate Water Filters
We use more than a dozen metrics to evaluate filtration systems. We research companies, pour through reviews and analyze customer feedback across hundreds of websites.
We verify NSF and WQA certifications — plus we do our own testing under real-world conditions, so you’ll know first-hand what to expect. Knowledge is power, and it’s our gift to you.
Which Filter is Right for You?
Amazon sells more than 10,000 water filters. If you don’t know where to start shopping, you’re not alone. So, let’s refine your choices based on a few key factors.
Do you own or rent your home?
Whole-house filters are permanently plumbed into your main water line. The return on investment is low if you’re in a short-term rental because you can’t take it with you.
And if the landlord doesn’t approve, you’re out of luck. But that doesn’t mean you can’t buy a water filter — you’ll just need a different type. We’ll discuss your options in depth.
A filter that doesn’t target the contaminants unique to your water supply is a waste of your money. We’ll explain more about water quality and testing.
If it takes more time than you have to maintain a water filter, or it doesn’t produce enough filtered water to meet your needs, it’s not the right fit. We’ll help you find you one that is.
The best water filter for you is one that fixes your water quality issues and fits your lifestyle for a price you can afford. Keep reading — we’ll put the puzzle pieces together.
Understanding Water Quality
Water quality is the sum of what it contains. The more you know, the easier it is to choose the right water filter.
If you drink city water, your annual consumer confidence report lists the problem contaminants in your water supply from heavy metals and minerals to chlorine and fluoride. It’s mandated by the Environmental Protection Agency and produced by your water utility.
If you drink well water, testing is up to you. The CDC suggests annual testing for pH, nitrates, total dissolved solids and coliform bacteria. It’s a start, but if your water looks, smells or tastes bad, we recommend the Tap Score Essential Well Water Kit. It tests for 52 of the most common contaminants in well water.
Contaminant Removal Capability
Different types of filters remove different kinds and quantities of contaminants — no one system does it all. Carbon filters, for example, reduce chlorine, lead and volatile organic compounds (VOCs). But sometimes, that’s not enough.
In some parts of the country, municipal tap water contains dozens of chemicals and other contaminants from pharmaceuticals to microplastics. The filter you choose should reflect the contaminants in your water supply.
What to Look for in a Water Filter
There are two types of water filters — point-of-entry (POE) or whole-house filtration systems, and point-of-use (POU) filters.
Whole-house water filters are integrated into your plumbing system and treat water home-wide.
POU filters treat water from one tap. Examples include:
Under-Sink Water Filters
Under-sink filters treat small volumes of water for drinking and cooking. Installed under the kitchen sink, installation requires no permanent changes to your plumbing.
Pros include price. Under-sink filters are inexpensive, yet some can remove as many major contaminants as a whole-house filtration system. And because they’re not permanent, they’re ideal for renters and nomads.
Cons include size. The storage tank on a reverse osmosis system fills an entire cabinet.
Countertop filters come in two types — filters that attach to the faucet via a hose — and freestanding, top-loading filters with a spigot. Both are equally capable.
Freestanding filters offer better aesthetics but pouring in water is a chore. Faucet-attached filters are more convenient, but the hose is a hassle.
Faucet Water Filters
Faucet filters attach to the faucet in place of the usual aerator. Most are just carbon filters, but better models kick it up a notch with microfilters that remove a broader range of harmful contaminants.
Pros include tool-free installation and price — if you have $20, you can have better drinking water. And they install in seconds without tools or plumbers.
Filtered Water Pitcher
Most water filter pitchers are just activated carbon filters. But the best water pitcher filters boast enhanced filtration media that reduces hundreds of harmful contaminants from heavy metals to uranium. It’s a lot of bang for your buck.
Pour tap water into the top chamber and it flows through a cartridge and into a filtered water reservoir below. Store it in the refrigerator for access to clean drinking water anytime. Ultra-convenient, some are even dishwasher-safe.
Pros include cost — a basic Brita pitcher starts at $25. Better models like the PUR filter cost a few dollars more. Cons include capacity. If you have a thirsty family, you may fill them a dozen times a day, and they rarely hold enough to meet cooking needs.
Refrigerator filters are activated carbon filters that purify ice and water from built-in dispensers. But you can still enjoy better-tasting ice by adding an external filter if you don’t have one built in.
Inexpensive, they attach to the water line behind your refrigerator. For most homeowners, it’s an easy DIY project.
Showerhead filters are a type of faucet filter for your shower tap. Screw it on and it removes contaminants like chlorine that can irritate your skin and respiratory tract.
If you can’t afford a whole-house filter, installing a faucet filter in the kitchen and a showerhead filter in the bathroom is an affordable solution.
Water Bottle Filters
For filtered water on the road, try a water bottle filter. Like a filter pitcher, just fill it and go. Brita makes both bottle filters and pitchers.
Water filters use one or more of these filtration methods to eliminate contaminants from drinking water.
The adsorption process draws contaminants to solid surfaces like activated carbon. Its expansive surface area is a magnet for fine sediment, chlorine, lead, pharmaceuticals and chemicals from glyphosate to trihalomethanes.
But not all activated carbon filters are equal. How the carbon is activated, processed and enhanced determines it’s filtration capability. Catalytic carbon, for example, is activated using iron hydroxide to increase adsorption of negatively charged contaminants such as PFOA/PFAS. Enhancing carbon with KDF media increases the amount of lead it reduces.
And carbon isn’t the only adsorptive media used in water filters. Activated alumina, for example, is similar, but it targets fluoride, selenium and arsenic.
The reverse osmosis process relies on a semi-permeable membrane laced with microscopic pores. Like a paper sediment filter for dirt, molecules larger than the pore size are eliminated.
Reverse osmosis filters remove 99% or more of most tap water contaminants, including heavy metals, fluoride, bacteria, parasites and hard minerals. They struggle with sediment, chlorine and certain chemicals, however, so most are part of multi-stage reverse osmosis systems that include sediment and activated carbon cartridges.
The gold standard for filtration, under-sink reverse osmosis systems are budget-friendly and effective. But they waste water. A reverse osmosis filter produces two gallons of wastewater for each gallon of purified water it produces. Still, RO filters can make even the most brackish water drinkable. For some families, it’s the only solution.
Distillation is one of the world’s oldest filtration methods. As water boils in the bottom chamber of a two-chamber pot, steam is captured and condensed. The purified droplets are collected in a carafe and contaminants with a boiling point lower than water are left behind.
Distillation is an inexpensive filtration method, but it has limitations. A mid-sized home distiller produces a maximum of 6 gallons per day of filtered water. And it requires electricity to operate — an average of $0.25 per gallon and climbing given today’s skyrocketing power rates.
Still, you can purchase a distiller for less than $100, and it produces water so pure that you can use it in medical devices like CPAP machines. If you have to buy distilled water, it could pay for itself within two years.
Nanofiltration is similar to the reverse osmosis process but without producing wastewater or removing the healthy minerals that give water its refreshing taste. It removes contaminants as tiny as 0.01 microns.
Ion exchange filters use electrically charged resin beads to pull contaminants out of water. Opposites attract, so beads carry a positive or negative charge depending on the target contaminants.
In a water softener, for example, negatively charged beads target positively charged hard minerals, trapping them in the softening tank. An occasional burst of salt water from the brine tank breaks the electrical bonds, sending contaminants down the drain while regenerating the resin.
Ion exchange media can also be blended with carbon to enhance its contaminant removal capability. Brita’s filters are a good example — it’s why they remove more contaminants than average carbon filters.
Water conditioners treat hard water, but they don’t remove minerals. Instead, they change their molecular structure so that they can’t form limescale.
Conditioning addresses some but not all hard water issues. But it requires no salt, uses no electricity, produces no wastewater, and it’s better for the environment.
Ultraviolet light is one of the few filtration methods guaranteed to make water potable. Other water filters remove some pathogens, but not enough to protect you from illness. UV light renders bacteria unable to reproduce or cause disease.
Used alone or as a backup filtration system, a UV water filter is the best protection against waterborne microbes as long as the bulb is replaced regularly.
A filter’s capacity is how many gallons of water it can treat before it needs to be replaced. High-capacity filters last longer. Low-capacity filters are cheaper, but you’ll replace them more often.
Lifespans vary significantly. Some whole-house water filters are good for a million gallons or more while cartridges in an under-sink filter need changing every few months.
Choosing a water filter with the right capacity is the key to taming maintenance chores. A single person, for example, may get six months out of a faucet-mount filter. A large family will have to buy replacement filters by the crate.
Flow rate is the maximum number of gallons that can flow through a filter per minute. The faster the flow rate, the better your water pressure. The industry average for whole-house systems is 6-7 GPM, but the best water filters offer 10 GPM or more. Anything less and brisk showers turn into trickles.
Flow rate is less impactful with point-of-use filters. Refrigerator filters, faucet-mount models and pitcher filters average 0.5-0.75 GPM — it’s plenty for most folks.
Several factors, including the size of your plumbing, your incoming water pressure and your water quality, impact flow rate. But the filtration method has the most impact. Water naturally flows faster through a loose granular carbon filter than it does through a reverse osmosis membrane.
Installation & Maintenance
DIY installation can save you $1000 or more on a water filtration system. Plumbing skills are a must for installing whole-house filters. But setting up under-sink filters, faucet-mount filters and pitcher filters requires no technical skills.
Filter replacement is straightforward. The maintenance schedule varies based on the type of filter. A water conditioner, for example, is a self-cleaning, set-it-and-forget-it system.
But most filters need changing as follows:
- Water softener resin every 5-10 years
- Whole-house carbon media every 10-15 years
- Reverse osmosis membranes every 3-5 years
- Faucet filters every 1-6 months
- Refrigerator filters every 6-12 months
- Countertop filters every 3-6 months
- Showerhead filters every 3-6 months
- Filter pitcher cartridges every 1-3 months
- Water bottle filters once a month
- UV lightbulbs every 12 months
Replacement Filter Costs
The cost of replacement filters contributes to the annual operating cost of a filtration system.
On average, here’s what you’ll spend annually:
- Reverse osmosis membranes — $75-$100 per unit
- Whole-house carbon media — $150-$300
- Water softener resin — $400 every 7 years
- Faucet filters — $30
- Refrigerator filters — $60
- Countertop filters — $80
- Showerhead filters — $80
- Faucet filters — $70 a
- Filter pitcher — $80
- Water bottle filters — $70
- UV filters — $50
Maintenance costs add up, but it’s a fraction of what you’d pay for bottled water. A single cartridge can replace thousands of single-serve water bottles. It’s a bargain for you and the planet.
Certifications are the best assurance you have that filters are safe and effective. The two most pertinent are:
The National Sanitation Foundation is a non-profit organization that tests water filters for quality and performance. Certified models are independently tested and guaranteed to perform as advertised.
Of the dozens of standards, these are the most reassuring:
- NSF 42 for chlorine reduction
- NSF 44 for water softeners
- NSF 53 for contaminants with adverse health effects, like lead
- NSF 58 for reverse osmosis water filters
- NSF 177 for showerhead filters
- NSF 401 for emerging contaminants
- NSF P473 for the removal of forever chemicals including PFOA and PFOS
Like the NSF, the Water Quality Association tests and certifies water filters. The standards are similar, but the WQA also considers environmental impact.
Gold Seal filters are performance-certified. Models with sustainability certification are money-savers. They use less energy and produce less wastewater than similar filters.
A good warranty protects your investment if something goes wrong. But it’s critical to read the fine print.
The best water filters have comprehensive warranties that cover both parts and performance — if your six-month filter only lasts three, you have recourse. But because water quality is so variable, most warranties only apply to defects in workmanship and not normal wear and tear.
Questions you should ask yourself include:
- Who pays for return shipping if the filter is defective?
- Does DIY or outdoor installation void the warranty?
- Does the warranty cover both parts and labor for repairs?
Some manufacturers offer extended warranties for an additional fee. It’s an option worth considering if you’re on a strict budget.
Frequently Asked Questions
City water may contain contaminants that can be unhealthy and tasteless. Even disinfectants can have adverse effects. Lead contamination is common in older communities, and water treatment errors occur. We’d rather be safe than sorry – invest in a filter to ensure your health and safety.
Well water is synonymous with purity, but the truth is — groundwater can be as contaminated as city water. At a minimum, you’ll likely need a sediment filter to remove sand, dirt and silt.
But well water can also contain bacteria, parasites, hard minerals, arsenic and chemical contaminants. Most well owners have some type of water filter.
The best water filters for contaminant removal are reverse osmosis systems and nanofilters. But there are exceptions. As filtration technology improves, other filters are catching up fast.
The best filter is an affordable water filter that removes target contaminants. Price doesn’t always reflect quality, but you won’t go wrong with an NSF-certified filter backed by a company with a proven track record.
Among whole-house filters, SpringWell CF Series filters are top performers. The Clearly Filtered 3-Stage under-sink system is a premium POU option.
For safe yet dirty well water, a sediment filter will do the job. But if it tastes bad, carbon filtration is recommended. For bacteria, chlorine injection systems and reverse osmosis filters with a UV light work best. Hard water requires softeners or TAC conditioners. With so many options, there’s always a solution.
If you need broader filtration than the Brita filter offers, the Clearly Filtered pitcher is the best water filter pitcher for overall contaminant removal. Or you could upgrade to a countertop filter like the Big Berkey or the Epic Nano.
Not only do water filters work, but they work well. The best water filters rely on the same technology used by treatment facilities. If you buy smart, you won’t be disappointed.
