#6 Waterdrop Filter

Waterdrop Filtration System

  • 320 gallons of refreshing water
  • 0.5 gpm steady flow
  • Ranges from 0.01 micron to 0.1 micron

Waterdrop, another relatively new name in the scene of water filtration systems, brings several fantastic features in their flagship product: the 320-Gallon Ultra Filtration System. As its name implies, this water filter can go through 320 gallons before having to be changed—which, for the average user, will last most of one full year.

The amount of quality and longevity this represents is staggering. You’d think that—with the amount of savings this would net you in unneeded filter replacements—you’d be expected to pay much more for this product! However, this isn’t the case. This incredibly long-lasting product is yours for the same price as many of its shorter-wear competitors.

This filtration system was the very first to innovate and practically use the UltraFiltration system, a system of filtering water which measures its pore size in microns—which are magnitudes smaller than the pore sizes of similarly priced models. This product gets rid of 99% of the chlorine in water, is ten times more absorptive than usual carbon filters, and gives you water that isn’t just clean and tasty—it’s downright silky.

Thanks to its steady 0.5 GPM flow rate, stutters and uneven flows are a thing of the past. With the Waterdrop Ultra Filtration System, it’ll be just like using your regular kitchen faucet—only much, much better.

#7 Instapure Filter

Instapure F2 ESSENTIALS Tap Water Filtration System Review


  • Chrome Base with clear cap
  • No tools necessary for installation
  • Reduces bad taste and odor from chlorine

The Instapure system provides a simple way to switch between filtered and unfiltered water - not a thing that most other filters do, assuming (as they do) that once you get filtered water, you won’t want to go back. However, that isn’t always the case! There are some projects for which unfiltered water will suffice.

Being able to go back and forth between filtered and unfiltered water gives you an important advantage: You’ll be able to extend the life of your water filters by a lot! Therefore, the simple switch that the Instapure F2 Essentials Water filtration System includes is a huge plus for longevity: a mark that the company behind it is caring about you, and not simply its bottom line.

This product is certified ANSI/NSF for the complete and effective removal of chlorine from your drinking water, which will not only make it a lot safer but also make it taste a lot better: definitely a win-win for you and your household.

This water filtration system features a sturdy chrome base which has a clear cap atop it, exposing an easy view of the filter itself so you can tell at a glance if it’s time to change the filter. The engineers who designed this product were clearly thinking of customer experience when they designed it—and it really shows.

Faucet Water Filter Buying Guide

Faucet Water Filter Buying Guide

Now that we’ve introduced the cream of the crop in the water filtration system world, let’s talk about some of the ways you can make the crucial decision: which faucet water filter is right for you?

To make that decision, it’ll help to have a basic understanding, first, of what you’re getting into. We all want clean and tasty water—it’s clear why you’d need a water filter. But how do these faucet water filters work? Read on as we tackle that question next.

How Do Faucet Water Filters Work?

The first thing to distinguish is the difference between purifiers and filters. The terms are often used interchangeably in the industry, but they’re actually technically differing things. A filter removes contaminants that are large enough to be caught by filters. A purifier removes even things that cannot be caught by filters.

If a water filtration system is referring to itself as a purifier, then you’ll want to ask how (aside from filtration) it’s cleaning the water it delivers from your tap system. Aside from that, here’s how water filters work:

  • Sediment Removal

This is the simplest (and most important) part of a filtration system. Once the water enters the filtration device, it passes through a non-woven screen that’s been placed just under the faucet. This gets rid of any larger particles of sediment that may be in your water reserves.

  • Activated Carbon Block

After all large sediment has been removed, the water will pass through a block of extremely compressed carbon (and often, other minerals, such as zeolite). These minerals have sponge-like properties wherein they can suck chemicals out of the water.

  • Chemical Removal

Building on the previous point, the sponge-like activated carbon block will remove chemicals from the water. How many chemicals it has time to remove is directly related to how long it comes into contact with the water. When you’re evaluating water filtration systems, you may want to keep an eye on how thick the activated carbon block is—that’ll determine how long the water is flowing through it, and, because of that, how many chemicals the block will be able to remove from your drinking water.

Next, let’s take a look at the benefits of having a home water filtration system.

What Are the Benefits of Faucet Water Filters

What Are the Benefits of Faucet Water Filters?

  • Healthier Water

There’s a basic premise that filtered water is much healthier for you. It’s true that drinking overly concentrated amounts of sediment and chemicals that may have laced their way into your groundwater won’t be the best for your system. Particularly if you live near a chemical treatment plant or other large factory known for dumping their contaminants into water reservoirs, a water filtration system might be a great investment.

  • No Foul Smell or Taste

Unless there’s a chemical polluting your water which is actually extremely dangerous, a smell or taste alone is unlikely to make you sick. However, there are many benefits you can receive from merely staying hydrated, and if having a weird smell or taste associated with your water makes it more difficult for you to drink water, that could be an excellent reason to look into a water filtration system.

  • No Chlorine

Chlorine is put into drinking water to disinfect it. Chlorine, when dissolved in water, breaks down into hypochlorous acid, which is toxic to some microorganisms that (when in water that is eventually drunk) can cause sickness in human beings. Therefore, a little bit of chlorine is usually a good thing! However, when there’s too much chlorine, or if someone in your home is allergic to it, removing the chlorine through an activated charcoal system will likely be beneficial.

  • No Nitrates or Nitrites

Nitrates and nitrites in water come from being near fertilization companies or products, so this is typically a problem if you live in a more rural area. If your water system only has low levels of this, it’s unlikely to be a huge problem; however, if there are large amounts of these two chemicals in your drinking water, you may be susceptible to methemoglobinemia (or “blue baby” syndrome). If this is the case, removing the nitrates and nitrites through a good purification system is a good idea.

  • Blocks Heavy Metals

Heavy metals in your drinking water are probably bad news because at high concentrations they tend to bioaccumulate — meaning, build up in your system — and when they’re inside you at very high concentrations, the effects can be poisonous. Whether there are heavy metals in your water will likely be a case-by-case situation. They can be caused by anything from environmental concerns to simple proximity issues like having your water delivered to you via lead pipes. If this is the case, investing in a water filtration system is a good step for your health.

  • Easy to Install

While many water filtration systems are billed with the option of paying for expert installation, most water filtration companies build their products with you in mind. Therefore, to install most of these systems (as well as performing simple ongoing maintenance, such as replacing filters) only requires a simple motion and a snap. Take the device out of the packaging it came in without breaking it and fit it over your faucet! Some manufacturers include adapters to fit different types of faucets.

  • Low Maintenance

Aside from cleaning the water filter on its surface whenever you happen to wipe down the rest of your sink, one great thing about water filters is that they don’t require any other maintenance! Simply make sure that you have some way of checking or remembering whenever the system will need a water filter change, and then you’re good to go. It’s as easy as using your faucet — but better.

  • Environmentally Friendly

Water filtration systems are good for the environment partially because they will help you drink more water and cycle more water through your home, helping contribute to your own health as well as the beneficial overall motion of the water cycle. You can feel good when you use your water filtration system, knowing that you’re doing your part to keep water clean, your home healthy, and your environmental impact low.

  • No Plastic

One of the most cogent arguments for water filtration systems is that it will reduce your need for specially bottled water. If you’re producing clean, tasty water in your home, you won’t need to buy it in a store—which can save you money and also reduce the amount of plastics in your home. As minting new plastic does take a toll on the earth, reducing your need for new plastic appliances and products (such as water bottles) will greatly assist in keeping your environmental impact as low as it can be.

Things to Consider When Buying a Faucet Water Filter

Things to Consider When Buying a Faucet Water Filter

We’ve listed out a lot of great reasons for purchasing a faucet water filter. They can be good for you, good for your home and family, and good for the environment—what’s not to love! However, once you’ve made the decision to purchase a faucet water filter, you have to choose which one to buy.

This can be an extremely overwhelming proposition. We’ve tried to help by listing out above some of the best and most affordable options on Amazon. We firmly believe that each of these would help you for years to come. However, that isn’t enough. You need to choose which one of the above products to purchase based on your innate knowledge of the strengths of your home.

This means that you’ll need to put on a pair of observing eyes and gaze around your home (or kitchen, or bathroom) with a bunch of criteria in mind which will help you know which water filtration system is right for you. Below, we’ve helped you out by listing a series of factors that should go into your water filtration buying decision.

  • Size

The first thing you’ll want to consider when purchasing a water filtration system is its size. Not only will its size affect how it fits on your faucet (which can matter both in terms of aesthetic and how it performs in your kitchen), but its size also determines how well it’s able to do its job.

The activated carbon block in a faucet water filter system is able to purify the water by extracting chemicals from any water which passes through it. The amount of contaminants the carbon block is able to sponge out is directly proportional to how long the water is exposed to the activated carbon block.

This means that the larger the filter is, the longer the water will be in the block; and the more time that the water is in the activated carbon block, the more chemicals it might be able to extrude. Therefore, in terms of size, for a faucet water filter, you’ll want to find the sweet spot between a filtration system that’s small enough for your faucet in terms of aesthetics and function and big enough that the filter itself (which contains the activated carbon block) is large enough to have a good impact on the purity of your water.

  • Filter Change Sensor

Will you want a filter change sensor included in your package? A filter change sensor is a small light which changes color or otherwise demarcates when the filter needs to be changed, taking a lot of onus off you as the filter changer. No longer will you have to remember specific days or times, no longer will you have to rely on handwritten notes on the calendar which can be erased or misinterpreted or forgotten! There’s a better way, and that better way often involves LED sensors on the filter itself that alert you to needed changes.

These filter change sensors often come in one of two varieties.

  • Light Sensors: The first sensor type is often a simple LED light sensor, one which often appears green at the beginning of the cycle and morphs over to red once the filter needs to be replaced. This takes a lot of guesswork out of your day! LED is also an energy-efficient lighting system which can last seemingly forever; you don’t need to worry about what’s providing the energy for that source.
  • Day Counting Sensor: Another option for a filter change sensor, the Day Counting Sensor allows you a little more autonomy as to when you’d like to change your filter. The Day Counting type of sensor does precisely what it says it will: it counts the number of days which have passed since the last time you changed your filter. Excellent for people on a budget or for people who want to go the maximum number of days between filter changes, the Day Counting Sensor will allow you to make that decision for yourself.
  • Filter Cartridge

Filter Cartridge - Water Filters

If you have a specific preference as to how you would like your filter cartridges to be presented, packaged, or otherwise formulated, this would be a good time to figure out what your proclivities are. Think about what you need to have removed from your water and what your values are in terms of how they are packaged and how recyclable your removable filters may be! After all, if you’re lowering your environmental impact through using the filtration system in the first place, you likely don’t want to have to do anything that would adversely affect the environment in the same fell swoop.

  • 360 degree Swivel

Depending on how the faucet water filtration system attaches to your faucet and how it’s made, the water filter may be able to pivot in a full circle around your faucet, allowing full dexterity—or not. Consider whether this is important to you! If your faucet is already stationary, you might not have issues with this; however, if you’re used to being able to manipulate precisely where your water flow hits your sink, you may want to consider looking for a brand which features the requested 360 degree swivel.

  • Different Finishes

This is purely an aesthetic choice. When it comes to differing finishes, none of the ways that your water filtration system presents externally will have any effect whatsoever on your quality of water. To make this decision, you’ll want to look around your kitchen. Note the finishes and colors you have in your room! This will influence what finish you’ll want on your water filtration system.

You’ll also have to decide if you want everything in your kitchen to match with a monochrome sort of look, or if you’d rather have a dozen different finishes and colors involved. Either way is great! It’s just another way that you can use your kitchen appliances to reflect your unique and personal style.

  • Ease of Installation

One of the great ways that water filtration systems differ from other typical kitchen appliances is that they are incredibly easy to install! Different brands may have differing levels of ease, however, so you may want to look into installation systems (perhaps by looking up examples on Youtube) prior to purchasing.

This is also a good chance to think about your prowess when it comes to tools. As the saying goes, the most expensive tool is the one that goes unused—so you definitely don’t want to overestimate your ability to install something, not be able to when it arrives, and then have to return or simply not use your water filtration device.

Fortunately, no matter the ease of installation involved with the product, each of our featured products above comes with the option to request expert installation along with the product itself. This can also, often, help with the warranty: many manufacturers will void a warranty if the product has been improperly installed.

  • Style

Water Filters Style

Going eco-friendly and healthy doesn’t have to be an unfashionable thing! Each of the faucet water filters we reviewed has a specific style and cache. Again, you’ll have to know yourself on this one: Consider what kind of aesthetic you’re going for in your kitchen, and then look over the photos and feature descriptions of your future water filter with a critical eye.

Do you need colors or finishes to match? Do you prefer smooth, unbuckled surfaces, or do you like it when there are a lot of moving parts? If there’s an LED light, does it matter to you that it might flash bright green or bright red? These are all things you need to think about when you’re looking for the perfect small appliance to add to your kitchen.

  • Cost and Warranty

Whenever you’re making an investment in your home, you definitely need to balance cost and value. You don’t want to buy the cheapest, flimsiest piece on the market, because that’s going to be something that you’re going to live with. However, you also don’t want to buy the most expensive one out there, if that’s going to break the bank for you!

Before you go shopping, definitely take the time to sit down with your bank statement and examine your options. Come up with a budget that will be good for you, and then simply exercise the willpower it may take to ensure that you don’t look at any products that are outside of that comfortable range.

One thing that may help you justify investing in a higher-priced model is if that model comes with a good warranty. A warranty may feature a price-back or replacement parts guarantee if you don’t like or use the product, or if the product breaks within a set amount of time after you purchase it.

Fortunately, each of the products we’ve linked above comes with a decent warranty and a product at a low price. However, you will still want to make sure that you decide what budgetary numbers will work for you and your wallet.

How to Install a Faucet Water Filter

How to Install a Faucet Water Filter

Now that we’ve discussed reasons to buy a water filter and the different factors that might go into your decision as to which water filter to purchase, let’s end by talking a little bit about how to install the faucet water filter you just purchased! After all, the story only ends happily if you’re able to use it as soon as you are able.

1. Turn off the Water Supply

To avoid any painful or embarrassing water spouts which could arise as a direct result of your tampering with your water system, it’s a good idea to start any plumbing project (no matter how minor) by turning off your water supply. It’s a quick step which has enormous results; don’t discount the positive mental effects of being clean and dry!

2. Remove The Faucet´s Aerator

Most faucets come equipped with a built-in aerator, a tiny device at the very end of your water faucet which helps add a bit of air to your water flow (which is why water comes spurting out of most faucets instead of merely flowing quietly). You’ll need to remove this in order to attach your faucet water filter to the faucet.

Fortunately, most aerators are built to come off quickly and easily, often without any tools. If you need a tool, likely the most intense one you’ll need is a screwdriver. If you need to know precisely what your aerator looks like, you’ll want to look up the specific brand and model of your faucet on the Internet—that’ll help you find a picture of exactly what you’re trying to remove (and it may even include instructions!)

3. Clean the Buildup

This part may be a little gross, but it should also be motivating in that what you’re removing from your faucet now is exactly what you’ll be removing from your water via the filtration system you’re about to install! Get some hot water and a clean towel, and make sure to get the gunk all out of there.

4. Check if You Need an Adapter

While the manufacturers of faucet water filters have tried to make their filters as universal as possible, sometimes an adapter unit will be required. Some of the products we’ve linked above include these adapters—but it’s always a good idea to check the make of your sink and faucet against the shape of the filter, just to make sure that you won’t be frustrated by a bad fit once you have the product at home.

5. Attach the Water Filter

This part speaks for itself! Click the water filter on to your faucet.

6. Flush the Cartridge

You’ll want to fully saturate the water filter for about a minute before drinking any of the water that comes out, just to make sure it works properly!

Faucet Water Filter Cleaning and Replacement

As far as ongoing maintenance goes, the makers of the water filtration systems have tried to keep it as simple as possible (which is good for you!). Wipe down the water filter whenever you clean your kitchen, and make sure to remember how often to change the water filter—whether that be by a note on your calendar or an LED sensor on the device itself.
