The 6 Best Ceramic Water Filters – Reviews 2021
1. Zen Water Systems 4G-MP Countertop Filtration – Best Overall
You’re most likely to drink healthier filtered water if you can make it convenient. Luckily, the Zen Water Systems 4G-MP Countertop Filtration System makes it very convenient and easy to get filtered water any time you want. And since it will be on your counter in plain view, you’ll get regular reminders to drink the healthy and delicious water from your filter.
If you’re going to keep a big bulky water filter on your counter, it needs to be attractive, Luckily, this filter looks elegant, so it’s got both form and function. Of course, it’s our favorite because it performs better than the rest of the pack. We weren’t thrilled that it’s made from plastic, but at least it is BPA-free. And the magnetized spigot was a nice touch.
With a five-stage mineral filter and a micro-ceramic filter as well, this filter removes a plethora of impurities, including bacteria, chlorine, chemicals, and more. Plus, it adds healthy minerals back into your water, boosting its alkalinity for even further health benefits. The ceramic filter is good for 1,000 gallons and the five-stage filter is good for 500 gallons, so it’s safe to say that this is a low maintenance system.
2. SimPure Countertop Water Ceramic Filter – Best Value
What if it was affordable to add a second tap to your sink that was devoted just to filtered water? Well, with the SimPure Countertop Water Ceramic Filter it can be. This reasonably-priced filter sits beside your sink, adding a second faucet that’s just for providing delicious filtered water. But don’t worry, it’s easy to install by simply attaching the hose to your existing faucet. No changes to your piping are necessary and it’s a non-permanent installation.
This filter is very lowmaintenance with a long-lasting six-month filter life. And unlike some of the filters we tested, it has a very respectable flow rate of up to two gallons per minute. However, since it’s got a hose that attaches to your faucet, it makes your sink less convenient to use, especially if you need it for washing dishes or anything similar.
With this filter, you can have nearly unlimited filter water on tap in your kitchen. It filters out benzene, radon, chlorine, heavy metals, and more. Considering how affordable this filter is for six months’ worth of filtered water, we think it’s the best ceramic water filter for the money.
3. Crystal Clear Supply Undercounter Water Filter – Premium Choice
If you’re looking for the convenience of having filtered water on tap without the drawbacks of a countertop unit, then the Crystal Clear Supply Undercounter Water Filter is an option to consider. It’s got a dedicated faucet for filtered water, but the filters are housed under the sink instead of beside the sink on your counter. This is much less of an eyesore and leaves all your counter space open for other uses.
Most of the filters we tested had a lifespan of about 6 months to one year. But this filter has an impressive 3-year lifespan, meaning you can filter 12,000 gallons before you need to replace the filter cartridges. And these filters do a good job of removing impurities, filtering out E. Coli, Salmonella, Fecal Coliform, cysts, bacteria, and more. Even better, it still leaves all the healthy minerals you need, ensuring you get as pure of a drinking experience as possible.
We were surprised at just how easy this filter was to install since it used all push-connect fittings, eliminating the need for professional installation. We were glad to save the extra money since this is one of the more expensive filters already.
4. Internet Prepper Ceramic Water Filter Kit
If you’re more of the hands-on type and you enjoy a good DIY project from time to time, then you may prefer the Internet Prepper Ceramic Water Filter Kit that lets you build and assemble you’re own gravity filtration system with the included ceramic filter and spigot. Using this system, you can filter up to 14 gallons per day, providing plenty of water for a whole family.
While this kit doesn’t include everything you need to build your filter system, it does include the important parts. The rest of your supplies will be easy to find since all you really need are some buckets from a local hardware store. You’ll also need a drill and a bit to assemble everything, so make sure you have the necessary tools on hand.
This filter can remove quite a few contaminants to leave you with pure and clean drinking water. It removes arsenic, hydrogen sulfide, chlorine, aluminum, pesticides, bacteria, cysts, e. Coli, and more. With filter pores of just 0.2 microns, it will strip all the unwanted impurities from your water.
5. Doulton W9330958 SuperCarb Under Sink Filter System
The Doulton W9330958 SuperCarb Under Sink Filter System is an easy, albeit expensive way for you to add an unlimited supply of filtered water to your home. There are cheaper alternatives that function just as well, which is why this filter is ranked lower on our list.
This system hooks into your kitchen sink’s main water line and provides a second tap at the sink that’s just for filtered water. It’s not very difficult to install, thanks to the included push connectors. However, the included fittings won’t work with every sink, so you may need to make a trip to the hardware store to get some more parts to make it fit with your specific sink.
The Doulton filters have a lifespan of 12 months, which is about average for this type of filter. But we liked that these filters can be washed. If your water flow starts to slow down, a good washing can restore flow and prolong the filter’s lifespan.
6. Doulton W9331032 HCPS Countertop Filter System
Though it’s easy to install and not too expensive, the Doulton HCPS Countertop Filter System still didn’t manage to impress us. It’s not the most attractive system, which matters since it will be sitting on your counter in plain view. But it does provide almost unlimited filtered water on tap.
To hook this filter up, you simply attach the hose to the end of your kitchen faucet. Then, you can use the diverter knob on the attachment to divert the water from your kitchen faucet to the filter. The water will then come from the filter’s dedicated faucet.
The Doulton filter seemed to clog more often than any of the other filters we tested. Luckily, it can be washed out to restore flow. But we had to do it so often that it became an annoyance. Plus, the water filtered through this cartridge doesn’t taste very good. And worst, this filter seemed to add grit to the water, making it a very unpleasant drinking experience. We prefer water that’s enjoyable to drink, which is why the Doulton HCPS Countertop Filter has earned the lowest position on our list.
Now that you’ve seen how some of the most popular ceramic water filters compare, it’s time to decide. But before you do, we think it might be helpful to discuss the important factors that should be at the forefront of your thoughts while you make this choice.
Choosing A Ceramic Water Filter
When you’re deciding on a ceramic filter to provide your family with safe and healthy drinking water, there are several considerations to keep in mind. Ceramic water filters can come in different forms with varying levels of functionality, so just picking any old ceramic filter won’t do. The first choice to make is what type of filter system you want.
Countertop filters will sit on your counter as the name implies. This makes it easy and convenient to get water since it’s right next to your sink where you’d normally get water from anyway. But this also means that you’ll be sacrificing some counter space. The filter will always be visible, so it will affect the overall look of your kitchen.
There are two main types of countertop filters. The first is a gravity filter with two reservoirs. You pour water into the top reservoir and travels through the filter and down into the bottom reservoir where you will retrieve your drinking water from. These filters require no installation and can simply sit on the counter. But they’re not the most convenient since you’ll constantly need to refill it if you want to continue to have filtered water.
The other type of countertop filter has a built-in dedicated faucet for filtered water and a hose that attaches to your existing faucet. You can turn the built-in diverter switch to send the water from your kitchen faucet to your filter faucet, supplying you with a nearly endless amount of filtered water on tap. But the hose is an eyesore and it hinders the normal functionality of your sink.
If a countertop filter doesn’t sound like the right fit for you, then you might consider an under-sink filter instead. As the name implies, these filters are mounted under your sink where they’re hidden from view. They have a dedicated faucet that will be installed on your sink. This type of filter will hook directly into the main water line for your sink, but you won’t have to divert the flow to use it. When you turn on the filter faucet, you’ll get endless filtered water.
You won’t have to sacrifice any counter space for an under-sink filter, and it won’t affect the look of your kitchen. But they’re much more difficult to install. You may even need to hire a professional. And they tend to be more expensive than the simpler countertop filter systems.
Once you’ve decided on what type of ceramic filter system you want, the next consideration is the filter lifespan. Filter cartridges vary drastically in what they can remove from your water and how long they can do it before they need to be replaced. For ceramic filters, a lifespan of six to 12 months is about average. But if that still sounds like more maintenance than you care to perform, you can find ceramic filters with lifespans of up to three years!
After filtering our water through many different ceramic filters, we’ve settled on three systems that we preferred over the rest. If you’ve read our reviews, then you already know how they compare. But to make sure they’re fresh in your mind, we’re going to quickly summarize our recommendations.
The Zen Water Systems 4G-MP Countertop Filter was our favorite overall. It’s an elegant looking system that strips all the impurities from your water while adding essential minerals to boost alkalinity. The filters have 500-gallon and 1,000-gallon lifespans and the entire device is BPA-free.
For the best value, we suggest the SimPure Countertop Water Ceramic Filter. This system adds a second faucet to your sink that’s just for filtered water. It offers an impressive flow rate of over two gallons per minute with a great six-month filter life.
Finally, our premium pick was the Crystal Clear Supply Undercounter Water Filter. It strips contaminants while leaving healthy minerals in your water and each filter lasts for an incredible three years between replacements.
