Apex Countertop Drinking Water Filter
Suppose you are looking for a simple and affordable way to increase the healthy mineral content in your drinking water while also removing harmful contaminants. In that case, the Apex Countertop Drinking Water Filter is a great option.
One of the biggest highlights is that the Apex Countertop Drinking Water Filter is easy to install. It comes with all of the hardware you need, plus instructions for DIY installation. It simply screws onto a standard kitchen faucet; however, it must be a standard faucet.
Although this unit takes up a bit of space, it’s not too bad compared to the other options. Moreover, we do have to say that it actually looks quite stylish.
To make your water more alkaline, the Apex Countertop Drinking Water Filter features a set of alkaline beads to help accomplish this goal, thus providing you with various health benefits. Keep in mind that this filter should raise the pH level of your drinking water to around 8.0.
This filter can do so for up to 750 gallons of water before it needs to be replaced. On that same note, the Apex Countertop Drinking Water Filter has a replaceable filter cartridge, so you can y replace the media instead of having to buy a new filter.
This is an efficient multi-stage water filtration system with KDF-55, various micro-felt pads, and granular activated carbon.
These filtration media work together to remove harmful substances from your drinking water, including but not limited to sediment, dirt, rust, radon, bacteria, heavy metals, chlorine, chloramine, odors, tastes, and colors, organic chemicals, and more.
The good part about the Apex Countertop Drinking Water Filter is that it’s just a small, simple, and affordable water filtration system that fits neatly on your countertop while looking decent and not costing a fortune. It’s nothing revolutionary, but it gets the job done, and that’s what we really like. It doesn’t have to be fancy, just as long as it works.
What is not so great about the Apex Countertop Drinking Water Filter is that the filter is hard to replace; getting the system open to remove the old filter and replace it is not easy.
It takes a good deal of muscle power to open. It has also been noted that prolonged exposure to sunlight may also cause an algae bloom at the top of the filter.
- Fairly stylish
- Lasts a long time
- Works as advertised
- Tastes decent
Replacing the filter can be a challenge
Express Water ROALK5D Reverse Osmosis Alkaline Water Filtration System
Suppose you want a high-quality under-sink water filtration system that can remove virtually any and every contaminant from your water while also adding healthy minerals. In that case, the Express Water ROALK5D Reverse Osmosis Alkaline Water Filtration System is something to consider.
The most impressive part about the Express Water ROALK5D Reverse Osmosis Alkaline Water Filtration System is that it is a ten-stage water filter. That’s right, ten stages. We want to look at each of these ten stages and what they do for your drinking water.
The first stage is a sediment filter that removes dirt, rust, and other sediment from the water, thus protecting the rest of the filter, your pipes, and your hardware from sediment buildup and damage.
The second and third stages consist of two types of activated carbon that can remove chlorine, volatile organic compounds, and odors from the water.
The fourth stage is the reverse osmosis membrane that is tough on various contaminants that most other filter types cannot handle, like chromium, total dissolved solids, fluoride, radium, lead, and arsenic. On a side note, the tenth stage is also a carbon filter, just to remove any lingering tastes and odors.
Stages five through nine of the filtration process consist of mineralization. In other words, these four stages add healthy minerals, oxygen, and antioxidants to the water. What’s more is that the minerals are ionically activated, which means that they attract more minerals from within the water, producing increased alkaline benefits.
What is worth noting is that the sediment filter and the carbon blocks need to be replaced only twice per year, with all of the other filtration media needing to be replaced only a year. All filter media comes color-coded, so you know what’s what.
The Express Water ROALK5D Reverse Osmosis Alkaline Water Filtration System features double-sealed filters to produce the highest filtration efficiency. There is also a leak-stop valve that stops water flow if excess water is detected. This unit can achieve a flow rate of about 0.8 gallons per minute, for a total of roughly 50 gallons per day.
Although there are a lot of components involved, the installation process is still fairly straightforward. The chrome faucet is beautiful.
The good part is that it’s just a really comprehensive and full-scale water filtration system that can remove virtually all contaminants from the water. The fact that it comes with four mineralization filters is a pretty big deal.
One thing that is not exactly great about the Express Water ROALK5D Reverse Osmosis Alkaline Water Filtration System is that it does take up a lot of space under the sink. Moreover, although rare, it has been noted that some of the valves can be a bit leaky.
- Good price
- Simple installation
- Easy maintenance
- Ten stages of filtration
- Removes virtually all contaminants
- Adds oxygen, minerals, and antioxidants
- Takes up a good bit of space
- Some of the valves may leak after prolonged use
APEC Supreme Alkaline Reverse Osmosis Filter System
This is a very high-end under-sink water filtration system that features six stages of mineralization and filtration, resulting in clean, clear, and healthy drinking water. One of the most significant selling points is its high output.
This is a six-stage filtration system. The first stage consists of a 5-micron sediment filter, removes sand, rust, dirt, and other particles from the water. This protects the rest of the filter and your pipes and fixtures from damage.
The second and third stages consist of activated carbon to remove chlorine, cloudiness, colors, and foul odors. These two stages can also remove volatile organic compounds, as well as some other common chemicals.
The fourth stage is a high-rejection TFC reverse osmosis filter, which can remove arsenic, lead, fluoride, chromium, radium, and 99% of all total dissolved solids (TDS). The fifth and final stage of filtration consists of coconut shell refining carbon for complete contamination removal.
The APEC Supreme Alkaline Reverse Osmosis Filter System has a last calcium carbonate stage that effectively mineralizes the water after it has been filtered; it should raise the pH level of your drinking water.
What’s really cool about the APEC Supreme Alkaline Reverse Osmosis Filter System is that all filters are super-capacity filters that last for a year before they need to be replaced. Moreover, unlike many other mineralizing RO filters, this one leaves your water tasting pretty decent.
There is also the fact that the APEC Supreme Alkaline Reverse Osmosis Filter System is relatively easy to install. Remember, this is an under-sink filtration system, not a whole house system, so be aware that you will need to have a good bit of space under your sink, but that said, it should be pretty easy to install.
Everything is color-coded for ease of installation, and you should be able to do it without professional help.
We really like the APEC Supreme Alkaline Reverse Osmosis Filter System because it is simple to install and maintain. It has so many benefits; it’s durable and doesn’t cost a fortune. It’s just a simple and effective way to make your water healthier to drink.
What is not good about the APEC Supreme Alkaline Reverse Osmosis Filter System is that although it is supposed to be a high-flow system, it seems to have problems achieving a high flow rate. Some people have figured out how to turn up the pressure, and others have not.
- Simple installation
- Five efficient water filtration stages
- Adds lots of high-quality minerals to the water
- High-quality calcium carbonate made in the US
Some issues with the flow rate
Pure Hydration Alkaline Water Machine
If you are looking for a stylish filter for your drinking water that attaches to your tap, sits on the counter, and has a dispenser you can put a glass under, the Pure Hydration Alkaline Water Machine is a great product.
The Pure Hydration Alkaline Water Machine looks like an espresso machine or small appliance that you put on your countertop, which is what it is. We appreciate that it looks decent because many water filters are not exactly stylish.
Moreover, another benefit is that although it takes up a bit of counter space, it doesn’t take up any room under your sink, not to mention that it is straightforward to install. However, there is additional hardware available that will allow you to convert it into an under-sink model.
It comes with the required installation hardware, plus a diverter valve, so you can screw it right onto your kitchen faucet. The diverter valve allows you to use the sink as usual or divert the water to the Pure Hydration Alkaline Water Machine for filtration. You also get a kitchen faucet.
In terms of the filter media, they’re quick-change cartridges, so there is not much work involved. Keep in mind that the Pure Hydration Alkaline Water Machine has various stages of filtration to make your water as clean and clear as possible, so let’s take a quick look at each of these stages.
The first stage is a resin filter that removes heavy metals from the water; it also acts as a water softener. The second stage is a compressed ceramic diatomic filter to remove small particles like rust and dirt from the water.
The third stage is an activated carbon block infused with magnesium, with the carbon removing various bacteria, microbes, viruses, and many other chemicals from the water. In contrast, magnesium helps add antioxidants to the water.
The fifth stage is another carbon block with a mineral chamber. That mineral chamber is loaded with different minerals designed to make the water more alkaline.
What’s really nice about the Pure Hydration Alkaline Water Machine is that it is so simple and straightforward. It doesn’t require electricity, the cartridges are easy to change, and installation should only take a few minutes, not to mention that this water filtration system is affordable.
It’s not like the Pure Hydration Alkaline Water Machine is bad, but keep in mind that it’s not nearly as effective at removing various substances from the water as the other filters reviewed today. The other filters on the list can remove somewhere around 1,000 substances from the water, whereas this one removes just over 220.
- Great for mineralizing the water
- Low maintenance
- Easy installation
- Space efficient
- Looks pretty nice
Filtration is limited
Invigorated Water pH Recharge 1F Alkaline Water Filter
This is the simplest, most basic, and most affordable alkaline water filter on the list today. For all intents and purposes, it is more or less a large and high-quality Britta drip filter designed to handle fairly large quantities of water (at least when compared to other filters of this type).
Unlike the other filters we reviewed, which all connect directly to your faucet or to the water supply, this one does not. We said it’s more like a Britta filter because you put it under the tap and manually fill it up.
This can be seen as a bad thing, but there is zero installation required. It’s just a simple plastic bin that contains a filter. You pour the water into the top of the Invigorated Water pH Recharge 1F Alkaline Water Filter; the water flows through the filter and then into the reservoir in the bottom, at which point you can use the spout to pour your drinking water.
The other benefit of not being connected directly to a tap or water supply is that you can pop the whole thing into the fridge, so not only will your drinking water be clean and clear, but cold as well. Keep in mind that the Invigorated Water pH Recharge 1F Alkaline Water Filter has a 2.6-gallon reservoir.
All things considered, the Invigorated Water pH Recharge 1F Alkaline Water Filter is actually good. It comes with a PH001 filter and an optional PH002 filter, which are both great multi-stage filters that can remove sand, dust, rust, fluoride, chlorine, chloramine, heavy metals, and more from the water.
It’s not as good as full-scale reverse osmosis systems, but it’s better than drinking unfiltered water. Moreover, this unit is designed to add iron, zinc, calcium, magnesium, selenium, lithium, iodine, other minerals, and antioxidants to the water.
What’s nice about the Invigorated Water pH Recharge 1F Alkaline Water Filter is how simple it is. This is truly old school, and we are OK with that. Just pour water into it, pop it in the fridge, and that’s it, and all for a fantastic price.
What is not great about the Invigorated Water pH Recharge 1F Alkaline Water Filter is its capacity and flow rate. This filter is not designed for speed or large quantities of water, just to filter a bit of drinking water for those times when you want a cold drink.
- Low maintenance
- No installation needed
- No electricity
- Decent water filtration
- Adds high-quality minerals
- Filtration is not as complete as with higher-end units
Before you spend money on water filtration systems that create alkaline water, there are a few essential points to consider.
One thing to consider is the type of alkaline filter you want to get. For instance, you can get whole house systems that filter the water before it gets to any of your faucets. Then there are under-sink filtration systems, which are mounted under a sink and filter the water for a specific tap, but not the whole house.
There are countertop models that sit on the counter and screw into your faucet. Finally, you have the older style as well, the Britta-style filter that requires you to pour water into it and then wait as it drips through the filter.
On a side note, this is the only type that you can put in the fridge, as it is not connected to anything.
Measure of Alkalinity (pH)
The second thing to consider is how alkaline you want the water to be, keeping in mind that 1 and 2 are super acidic, 7 is neutral, and 14 is the most basic. For most people, if you want your water to be as healthy as possible, aim for an alkaline level between 8 and 10.
Keep in mind that too much is not good. Simply put, pay attention to how many pH points the filter can raise the water.
Number of Plates
The next thing is how many plates or how many filter media pieces the system comes with. Without going into too much detail here, the more, the better. The more filtration plates the unit has, the better the filtering will be, not to mention that the plate type matters, which we will discuss in the section below.
Material of Plates
The material of the filtration plates is also important to consider, and there are many types, more than we can talk about today; do some research on this front.
Some of the best filtration materials or types include reverse osmosis membranes, activated carbon filters, water softeners, and sediment filters.
Although a low flow rate is not a deal-breaker per se, it is nice when you can filter water faster than at a snail’s pace. If you don’t want to go insane waiting for your water, aim for a filtration system that can handle 0.8 gallons per minute at least.
Before we call it a day, let’s answer the most common questions about alkaline water filters just so you know exactly what you are getting into.
What is an Alkaline Water?
Alkaline water is simply water that is alkaline or basic. Remember that the pH scale goes from 1 to 14, with 14 being the most alkaline. Seven on the pH scale is neutral, so alkaline water is any water with a pH level over 7, which means that it contains plenty of dissolved minerals.
What are the Benefits of Alkaline Water?
There are a variety of benefits associated with alkaline water. When it comes to your health, the benefits include blood sugar regulation and diabetes management, increased metabolism, alleviating arthritis pain, detoxification, faster post-workout recovery, reduced acid reflux and heartburn, and more.
Simply put, consider the individual health benefits of the various minerals that you get with alkaline water.
The Differences Between Alkaline Water and Regular Water?
Regular water is generally neutral, with a pH level of 7, whereas alkaline water is higher up on the pH scale, usually 8 or 9.
Do Alkaline Filters Remove Fluoride?
Standard alkaline filters do not remove fluoride from the water. One of the only filtration types that can remove fluoride is reverse osmosis. All of that said, none of the filters reviewed today are just alkaline filters.
Are Alkaline Water Filters Safe?
In general, yes, they are safe but keep in mind that if your body becomes too alkaline, you may experience gastrointestinal issues, mainly metabolic alkalosis, a condition that involves severe nausea.
When it comes down to it, we think that the best alkaline water filter is the Express Water ROALK5D Reverse Osmosis Alkaline Water Filtration System. It has the most stages of filtration and the most mineralization components of all filters reviewed here, not to mention that it has a reasonable flow rate, it’s easy to install, and not insanely expensive.
