🧾 Buyer’s Guide – How to Select the Best Water Filter

This guide covers everything you should keep in mind when searching for a water filtration system for your family.

📌 Personal Filtration Needs

Everyone has their own unique reasons for wanting to buy a water filtration system. Perhaps you want to cut down on the number of plastic water bottles you use, or your tap water doesn’t taste good, or you’re concerned about contaminants – or a combination of all three.

Think about when, and how, you’d be using a water filtration system. There are different kinds of water filters that suit different filtration needs.

Consider whether you’ll benefit most from a filter you can take with you on the go, a filter that provides clean water for your whole home, or a filter that you can store out of sight when not in use.

Understanding Water Quality

Your tap water quality is unique to where you live. Although tap water is generally safe to drink, there are still hundreds of possible contaminants that it might contain.

Ask yourself the following questions about your water quality:

  • Does your water come from a municipal supplier or private well?
  • Are there high concentrations of any specific minerals in your water?
  • What common contaminants might be found in your water?
  • Are there particular substances you know you want to remove?

Check out this guide to learn all about testing your home’s water quality.

🧫 Contaminant Removal Capability

Virtually every water filter with basic filtration capabilities can greatly reduce or remove chlorine, heavy metals like lead, and VOCs. But the best water filters can do so much more than that.

Different types of water filters remove different types – and quantities – of contaminants. You don’t always have to pay more money for more thorough filtration, either – there are plenty of water filter pitchers that can remove more than 100 contaminants nowadays.

If you want to achieve the purest drinking water, consider reverse osmosis systems.. Some of the more unique contaminants that RO systems can remove are sodium, mercury, barium, arsenic, selenium, nickel, total volatile organics, cyanide, algae, and silicate.

Of course, it’s not essential that you purify your water if you’re only dealing with a few select contaminants.

✅24 Specific Water Filter Buying Guides

🔍 What to Look For in a Water Filter

System Type

The main water filtration system types, and what they do, are listed below:

  • Water filtering pitcher – Water is added to the pitcher and moves through a filter, which traps contaminants
  • Countertop filter system – Water is added to a top container and flows through a filter into a lower container
  • Faucet filter – The water from a faucet is forced through a filter attached to the end of the spout
  • Whole home water filter – Unit is set up at water’s point of entry into a home, filters water flowing through the plumbing system
  • Reverse osmosis – Can be installed under a kitchen sink or on a countertop for point-of-use applications, forces water through an RO membrane and several filters
  • Shower filter – Attached to the end of a showerhead, removes contaminants like chlorine
  • Backpacking filter – Gravity filter type, water is added to the bag and passes through the filter at the bottom of an attached pipe
  • Water bottle filter – Works like a small pitcher, filters faucet, river, lake, and well water for drinking directly from the bottle
  • Water softener – Doesn’t technically filter contaminants, but removes magnesium and calcium ions, which cause limescale

Filtration Method

Though there are a wide variety of system types, some of them use the same filtration methods. The most popular methods, and how they work, are:

Reverse osmosis

A reverse osmosis filter system forces water through a semi-permeable RO membrane, which prevents most total dissolved solids (TDS) from passing through. These molecules are then eliminated through a waste pipe, and only tiny water molecules can pass through the RO membrane. Reverse osmosis is a highly effective filtration solution with a price tag to show for it.


The chemical process of adsorption is used in activated carbon, carbon block, or granulated carbon filters. During adsorption, contaminants are trapped inside the pore structure of the carbon filter media. An activated carbon filtering cartridge is the best adsorptive filter media because of its large surface area.


One of the oldest filtration methods is distillation. In the process, water is heated to extremely high temperatures and vaporized. The vapor then condenses back into liquid form. This process purifies water, as the majority of contaminants can’t evaporate and condense like water, and remain in the boiling tank after distillation.

Ion exchange

Ion exchange is traditionally used in salt-based water softeners. During ion exchange, calcium and magnesium hardness minerals are replaced with sodium ions, preventing scale formation. Ion exchange systems are designed to regenerate frequently to flush out the unwanted calcium and magnesium ions and replace the used sodium ions.

Water conditioning

A popular alternative to salt-based water softening is water conditioning, which alters the structure of hardness ions and prevents them from sticking to surfaces as scale. The most popular water conditioning technique is template-assisted crystallization.

Filter Capacity

The filter capacity measures the amount of water a filter can treat before it needs to be replaced. The capacity of a system varies depending on the system you opt for. The size and design of a filter greatly affect how long it will last. You will also see this expressed as a length of time.

Here’s how long the most popular media and cartridge filters typically last for:

  • Water filter pitcher – 2 months
  • Countertop – 4-8 months
  • Faucet – 2 months
  • Whole home – 3-6 months
  • Reverse osmosis – RO membrane: 2-5 years; additional filters: 6-12 months
  • Shower filter – 6 months
  • Backpacking filter – 2-6 years
  • Water bottle filter – 2 months
  • Water softener -10-20 years

Keep in mind that there’s other maintenance to consider aside from replacing filters or media. Even if a system has a high capacity, you may need to spend money on maintenance between filter changes.

Flow Rate

A filter’s flow rate determines how quickly it can process unfiltered water.

There are several filter types that use gravity to filter water, and have a slower flow rate of up to 20 minutes, depending on how much water is needed:

  • Water filter pitchers
  • Some countertop filters
  • Backpacking filters
  • Straw/ bottle filters (these use the force of suction, not gravity)

Other filter systems are hooked up to your water supply and use the force of water pressure to filter water. These filters include:

  • Whole house systems
  • Under-sink filters
  • Water softeners
  • RO systems
  • Faucet filters
  • Sediment filters
  • Showerhead filters

All water filters, whether they’re supported by your home’s water pressure or not, will experience a slow-down in flow rate as the filter becomes more clogged with sediment. The tap water quality in your home will, in part, determine how quickly you need to replace your filters.

Installation & Maintenance

Installation of a water filter depends on the type of system you’re using.

Systems that are easiest to install are those that don’t need connecting up to your plumbing are countertop units, filter pitchers, water bottle filters, and gravity filters.

Also easy to install are faucet water systems, which can be attached to your faucet without the need for tools, and showerhead units, which can be attached to your shower hose in the same fashion.

Units that are more difficult to install are under-sink systems, which need attaching up to your cold water line, and whole-house filtration system units and water softeners, which you need to attach at your home’s point of entry. If you don’t have much plumbing knowledge, a plumber can do the job for you at an extra cost.

The majority of filters require maintenance. Buying replacement filters is the biggest responsibility, and most systems require a replacement filter at least twice per year. If the system uses media or resin, it may require less frequent maintenance.


There are water filtration solutions to suit all budgets, and you don’t have to spend thousands on a filter to achieve the desired results.

Water filter systems fall into three tiers:

  1. Low-cost (between $20 and $200)
  2. Mid-price (between $200 and $600)
  3. High-cost ( $600+)

Low-cost systems include water pitchers, faucet water filtration systems, water bottles with a filter, and backpack water filtration systems. Though these have cheaper upfront costs, you’ll generally need to replace the filter more frequently (around every two months on average). Still, filter replacement cartridges for these systems are cheap, and maintenance will cost around $50-$100/year.

Mid-price systems include countertop filter units and some under sink filtration systems. These are a little more expensive, for both the unit and its replaceable components, but you may only need to replace their filter media once every year or more.

The highest cost systems are reverse osmosis units, water softeners, and whole-home filtration systems. These can cost thousands of dollars but provide the biggest benefits, either filtering your entire home’s water supply or greatly improving the quality of tap water.

📝 Filter Certifications

An official certification is the best indication of a filter’s performance. There are two common certifications that a manufacturer can apply for: a WQA certification and an NSF certification.


The WQA, or Water Quality Association, is a not-for-profit independent trade party that represents the water treatment industry. Manufacturers who have gained a WQA certification have been able to achieve a “certified level of professional expertise and are dedicated to high professional standards”.


NSF International is an accredited third-party certification body that tests and certifies water filter products to check that they meet their promotional claims. There are a number of NSF Standards that a product can be certified for, including:

  • NSF 42, for chlorine removal
  • NSF 44, for cation exchange water softeners
  • NSF 53, for contaminants with health effects, like lead
  • NSF 58, for reverse osmosis systems
  • NSF 177, for chlorine removing showerhead filters
  • NSF 401, for emerging contaminants
  • NSF P473, for the removal of PFOA and PFOS

❔ Frequently Asked Questions

Which contaminants should I be most concerned about in my drinking water?

It depends whether you’re more bothered about water taste or quality. If you’re looking to improve the taste of your water, a chlorine water filter can be used to remove the chlorine taste and odor from water. If your water has a higher-than-average lead content, look for a filter that is specifically advertised to remove lead. If you want to remove total dissolved solids (TDS), only a reverse osmosis filter system can be used.

Other city water and well water contaminants to be concerned about include harmful chemicals like pesticides and herbicides, volatile organic compounds, other heavy metals like mercury and arsenic, and microorganisms like bacteria and viruses.

Which water filter is best of all?

That’s impossible to answer! The best filter for you might be different from the best filter for somebody else. You may have a higher budget that allows you to consider thorough filtration options like reverse osmosis units, but these aren’t necessarily “best” for everyone. Systems like countertop filtration units can remove the most common contaminants, like chlorine and lead, for a fraction of the cost.

What’s the best filter for using to treat well water?

Anything that removes common contaminants often found in well sources, including heavy metals, fluoride, nitrates, organic compounds, and viruses and bacteria. Whole home systems, reverse osmosis systems, and systems designed specifically for treating well water, will work best for you.
