2. AquaTru Portable Countertop Water Filter System – Best For Apartments

So I tested the AquaTru Portable Water Filter System for two weeks and can attest to its effectiveness. This countertop water filter utilizes reverse osmosis technology to remove up to 99% of harmful contaminants, including arsenic, barium, cadmium, chromium, fluoride, copper, lead, and radium.
While it may not be my top pick, I still rank it as my #2 rated system in my best countertop filter list this year. The filter has a capacity of up to 90 gallons per day, making it suitable for families, and can be moved around for use in apartments or homes.
Installation is simple, requiring the system to be hooked up to your faucet and for water to be run through it. It works great for apartments or homes and is portable, allowing it to be moved around. However, it can only be connected to a standard faucet, so those with a hose or sprayer will need to replace their faucet before using this product.
The system does produce wastewater, called brine water, but this can be repurposed for other household tasks. While the filtration process may slow down water flow, this is common for most filtration systems, particularly those utilizing reverse osmosis.
For those with water pressure ranging from 40 to 80 psi, this is an excellent option for improving the quality of their drinking water. Whether you are an individual or part of a family, the AquaTru Portable Water Filter System is an effective and convenient solution.

3. Apex Countertop Alkaline Water Filter

Alkaline water is becoming very popular because it adds valuable minerals into the water and slightly increases the pH. Purchasing alkaline water is quite expensive and produces a lot of waste, so a countertop filter is a good option.
This water filter screws into any standard tap water and begins working. It has a five-step filtration process, including KDF 55, which reduces or removes bacteria, heavy metals, and microorganisms.
Water will also flow through granular activated carbon, removing or reducing chlorine, chloramine, benzene, and organic chemicals. Alkaline beads and calcite add in magnesium, potassium, and calcium.
Depending on usage, the filter media must be replaced every few months. The average filter should last about six months before needing to be replaced. Alkaline water reduces fatigue, promotes bone health, and supports the immune system.
Suppose you independently test your water to ensure the filter is effective. In that case, it is essential to note that the total dissolved solids (TDS) will not be reduced as the filter adds minerals into the water. In fact, the filter should increase the TDS in your water.
Additional Specification
- Ideal For: Apartments or Homes
- Capacity: 750 Gallons
- Flow Rate: 0.75 Gallons Per Minute
- Stage: 5-stage
- Key Features: NSF Certified

4. New Wave Enviro 10-Stage Water Filter

This small but effective water filter attaches to any standard water faucet. The product weighs a mere 8 ounces. It has ten filtration stages, including micron filters and pads, which are great for removing solid waste and separating different layers of filter media.
KDF-55, a very common filter media, is also used to reduce or remove chlorine and heavy metals. A fine mesh includes coconut shells and granulated activated carbon to remove bad odors and color from the water and organic matter like pesticides and herbicides.
An ion exchange resin within the filter reduces lead in the water. When the ten stages work together, they will reduce lead, mercury, chlorine, pesticides, herbicides, trihalomethanes, arsenic, PCBs, and organic matter.
The filter cartridge will need to be replaced every 1,500 gallons and is fairly simple to do. Be careful when you do so, though, because the housing is made of plastic and is vulnerable to cracking. Filter cartridge replacements are an additional cost; no extras come with the filter.
Additional Specification

- Capacity: 800 Gallons
- Material: Plastic

What To Look For When Buying A Countertop Water Filter
As someone who has reviewed many countertop water filters over the years, I understand how overwhelming it can be to choose the right one. Knowing which filter is best for your specific needs can be hard with so many different types and features available.

One thing to consider when choosing a filter is the type of filtration it uses. There are many different types, each with its pros and cons. For example, reverse osmosis filters are highly effective at removing contaminants but can be wasteful and expensive.
It’s also important to consider the price range of different filters. While some filters may seem to do the same thing, there can be a significant price difference between them. However, it’s worth considering whether a filter that removes 97% of a contaminant is that much better than one that removes 93%.
To help make the decision process easier, this buying guide will break down the significant features of countertop filters and explain how they can impact your decision. By considering factors such as filtration type, price, and effectiveness, you can find the best countertop water filter for your needs.
Filtration Type
There are so many different types of filtration on the market. All of them essentially do the same thing: they clean your water. But they each do it slightly differently and have pros and cons. Here is a breakdown of some of the more common filter types:
Reverse Osmosis
Reverse osmosis is arguably one of the most effective types of filters around. Usually, an RO system will remove up to 99.99% of nearly all water contaminants. That is a huge asset to people who live in an area with truly dirty water.
The downside of an RO system is it wastes a lot of water. Many people use the excess water to water their plants or do dishes. They also tend to be more expensive than a standard filter. For many, these cons are a small price for clean water.
Gravity-Fed System
A gravity-fed system is straightforward and low-maintenance. It is excellent for camping, cabins, or even your home. The method comprises two stacked chambers with a filtration device in between.
You fill the top chamber up with water, and the force of gravity will pull the water through the filter and out clean on the other side. It is a straightforward way to clean water and does not require a hook-up to a faucet.
The downside of a gravity-fed system is you have to remember to fill the top chamber. Unlike other filters, you cannot just turn on a tap and have the water start filtering. It does require a bit of planning and remembering.
Standard Countertop Tower Filter
The vast majority of the countertop filters look like small towers. They usually have a plastic or metal housing that holds and protects the filter itself. These filters are simple to hook and unhook from any standard faucet and are very travel-friendly.
While the design for these filters is pretty much the same, the filtration media and filter cartridge lifespan are usually different.
Alkaline Filtration System
Alkaline water has been gaining popularity in the last few years. An alkaline filtration system will filter water out, similar to a standard countertop filter, but contaminants will add essential minerals back into the water after filtering out.
Alkaline water will generally have a higher pH and usually add minerals such as magnesium, calcium, and potassium back into the water. These filters are usually meant for water that is already very clean and is more of a preference by the drinker than a necessity.
Length Of Filter Cartridge Life And Cost
Depending on your budget and lifestyle, the lifespan of the filter cartridge could play a crucial role in your decision-making process. For instance, if you’re a busy college student or have a large family, remembering to replace the filter every three months might not be feasible.
Most filter cartridges have a volume or time limit, indicating the number of gallons it can filter or the duration it can last. However, estimating how many gallons of water you consume is challenging until you start using the filter.
If you’re an individual or a college student, you’ll likely consume less filtered water than a family or someone living with a roommate. In such cases, you can expect the filter to last longer before needing a replacement. On the other hand, if several people use the filter, you’ll likely exhaust the filter’s capacity faster.
Replacing filter cartridges can be costly, and prices vary across different filters. Before purchasing a filter, check the cost of replacing the cartridge since you might have to replace it up to four times a year.
Conducting a cost analysis could be beneficial, as a pricier filter might be more cost-effective in the long run if you only need to replace it once a year. However, for some people, the benefits of a specific filter might outweigh the cost of replacing the filters.
Do The Contaminant Removal Percentages Matter?
For some, the contaminant removal percentages will play a significant part in decision-making. Most contaminants are already filtered out if your municipality has relatively clean water, such as Chicago, New York, or Denver.
In this case, you probably don’t need a filter to clean 99% of the contaminants from the water. If you live in a municipality with clean water, you likely want to remove something specific from the water, such as fluoride, which most cities will add to the drinking water.
If you live in a municipality with low-quality drinking water, you will probably be more interested in a filter that removes more contaminants. Some water in cities has high lead levels and other potentially dangerous contaminants. In this case, getting as much of it out of the water as possible before consuming it is essential.
If you do not know the status of the drinking water in your municipality, the EPA has some great resources to learn and understand more about the drinking water in your area.
Frequently Asked Questions
What are some of the different types of countertop water filters available in the market?
There are various types of countertop water filters available in the market. Common types include reverse osmosis, gravity-fed systems, standard countertop tower filters, and alkaline filtration systems.
How do you determine the lifespan of a filter cartridge, and why is it important to consider when buying a countertop water filter?
The lifespan of a filter cartridge is determined by its volume or time limit, indicating the number of gallons it can filter or the duration it can last. It’s important to consider the filter cartridge’s lifespan when buying a countertop water filter because it can affect how often you need to replace the filter cartridge, which can impact the overall cost and convenience of using the filter.
My municipal water is fairly clean; do I need a filter?
While you likely do not need a filter, if you are looking for a better taste or removing any additives your municipality puts in, such as fluoride, you might want to consider a filter.
Why should I get a countertop filter over other types of permanent filters?
A countertop filter is simple to install, usually costs less money, and can be moved easily from place to place. They are ideal for those in apartments or who move a lot but are great for houses.
How often do I need to change the filter cartridge in a countertop water filter?
The frequency of filter cartridge replacement depends on the filter’s volume or time limit and your household’s water consumption. Most filters have a lifespan of three to six months or filter a certain number of gallons before requiring replacement. It’s important to keep track of the filter’s lifespan and replace it promptly to ensure you get clean, safe water.
Are countertop water filters easy to install and use?
Yes, most countertop water filters are designed for easy installation and use. They typically come with all the necessary components, including adapters, hoses, and instructions, and can be installed in just a few minutes without any special tools. They are also easy to use, with most filters having simple on/off switches or valves to control the water flow.
Can a countertop water filter remove all types of contaminants from water?
While countertop water filters can effectively remove many contaminants from water, including sediment, chlorine, and heavy metals, they may not remove all contaminants. Some filters are better suited for specific types of pollutants, such as fluoride or lead, so choosing a filter that can effectively remove the contaminants you’re most concerned about is crucial. It’s also worth noting that some filters may not remove microorganisms, so if you’re worried about bacteria or viruses in your water, you may need to consider a different type of filtration system.
Conclusions
Whether you are simply looking for better tasting and cleaner water or need to remove potentially dangerous contaminants from your water, a countertop water filter can be a great solution.
Though there are different types of water filters and different features to go with each, there should be a filter that best fits your needs and works within your lifestyle.
Our top pick is the APEC Portable Countertop Reverse Osmosis Water Filter System, which will remove nearly all contaminants and provide extremely safe and clean drinking water. It is a system that is easy to install and extremely effective.
Hopefully, between the comprehensive buying guide and the recommendations for the best countertop water filter picks, a potentially overwhelming decision has been made more straightforward.
