Water filtration technology continues to advance in efficiency and efficacy. A reverse osmosis system is the gold standard of water purification, removing up to 99.9-percent of all harmful particles, hormones, and pathogens. However, many standard water filters now remove contaminants from tap water almost as well as an RO system.
Our best under sink water filter guide introduces you to the best under sink water filter systems. Searching, selecting, and spending money on the right unit to suit your needs, is an important lifestyle choice. We’re confident we have the best solution to protect the health of your household. Evaluate the options and make an informed purchase decision.
Things to Consider
Test Your Water with a Testing Kit
When evaluating your home’s needs for an under sink water filter, it’s critical to establish a base reading of the contaminants in your drinking water. Each state has specific guidelines set per the local authorities in line with the EPA set limits for pollutants.
To complete a test, order a water testing kit online. There are dozens of types available — the best test for more than 170 contaminants, including volatile organic compounds (VOC’s,) heavy metals, and inorganic chemicals.
These kits are relatively inexpensive, and they’re a great way to find out exactly what’s in the water you and your family are drinking. While testing kits are readily available and reasonably accurate, you should never take the results of a testing kit as indisputable.
For a more accurate assessment of your drinking water, call a professional testing service and have them evaluate the condition of your tap water.
Most manufacturers design their under sink filters to purify water in the kitchen. These systems typically feature large filtration capacities, with most averaging a 50,000-gallon lifespan. As filter technology advances, so does the filter longevity, and some brands have products that last for years between changes.
Whole-home filtration systems feature the most significant capacity when it comes to residential water purification. Some whole-home solutions filter up to 1-million gallons of water over ten years.
A reverse osmosis membrane can filter anywhere between 1,000 to 5,000-gallons before replacement. This capacity is far higher than an under-the-sink reverse osmosis unit, but the final water product of RO has a higher level of purity – with some systems returning minerals into the filtered water.
Easy to Install?
Look at the design of the filtration system you intend to purchase. Is it easy to install by unqualified professionals such as yourself? Most come with easy-to-follow instructions and require no special tools for installation. It’s possible to fit your filter and have it running a few hours after opening the box.
However, if you have no idea of how to even open a toolbox – you might want to consider hiring a professional to do the installation for you.
The filters themselves are easy to change. Some models come with clear filter housings that allow you to visualize when it’s time to change the filter. Replacing the cartridges require little effort. All you need to do is open the housing, remove the filter and replace it with a new one.
Some manufacturers specify that their filter cartridges require replacement every 6-months, while some last for up to 3-years – So, what’s the difference? Long-lasting filters typically feature better construction with improved filtering materials. Always consider the price you’re paying and how it relates to the quality of the system.
We’re not saying that there aren’t high- quality budget products available, but the rule of thumb is – you get what you pay for, and spending more on a high-quality brand means longer filter life, easy installation, excellent customer service, and easy filter changes.
Water quality is another contributing factor to filter life. Manufacturers test their products on municipal water. However, in reality, the further you live away from your local water treatment facility – the more contaminated the supply.
As water moves through the infrastructure, it collects more particles from the piping system – which end up in what you’re drinking. Therefore, if you live far away from your local reservoir or filter or treatment plant, you can expect your water to contain more foreign particles – such as heavy metals, which impact filter service life.
Most water filtration systems work using water pressure. Filters require minimum pressures of between 40 to 75-Psi to work efficiently. Households with low water pressure may not be able to benefit from a water filter, due to the inability of the water to pass through the filter membrane.
Another thing to consider is the fact that most water filters reduce the water pressure in your home during operation. If you currently have low water pressure in your pipework, it may adversely affect efficiency.
Why an Under Sink Water Filter?
Under Sink System Vs Counter Water Filter – 5 Benefits
Most countertop filters work on a 3-stage filtration process. An under-the-sink solution typically works with 5-stages. Therefore, the materials in the membrane come under less stress and last longer than countertop units.
More filtration stages provide improved water filtration efficiency. Most under sink systems feature reverse osmosis which removes 99-percent of all particles from drinking water, as opposed to 85-percent from conventional countertop filter units.
Under the sink systems munt to the back wall of your sink cupboard. They’re out of sight and out of mind, keeping your kitchen counter looking clean and free of clutter.
Wide Choice of Models
There is a wide variety of under sink units available, from 3-stage to 6-stage systems, and even some that use up to 9-stages of filtration, including UV treatment.
Better Water Quality
More stages of filtration provide improved water quality and fewer contaminants. Reverse osmosis systems even clean trace amounts of hormones, bacteria, viruses, and pharmaceuticals.
Under Sink System Vs Counter Water Filter – 5 Disadvantages
Reduced Water Pressure
Under sink systems work on your homes water pressure, if your home has low water pressure, it further exacerbates the situation and drops filter efficiency.
More Difficult to Install
Under the counter units require you to fit the filters, machine head, and run lines for the faucet. Some reverse osmosis systems come with a flush feature to connect with your waste pipe. While it’s possible to do the fitment yourself, some may need professional assistance.
Under sink systems typically cost a fair deal more than a countertop filter. However, they last longer and free up countertop space.
Monitoring and Maintenance
Since your units hidden away in the cupboard, you may not notice that they need changing. Under-sink systems run the risk of leaking without you being aware of it. Fortunately, most leading brands come with leak detection.
Under-sink filters link to a separate faucet. So, you’ll need to cut a hole in your sink to accommodate the tap. This circumstance becomes an issue if you have a granite or marble countertop.
Which Type of Under Sink Water Filter?
Simple Under Sink Filter
This system gets its name from the ease of installation – not the process in which it filters water. During the installation process, you’ll divert the cold water supply through the filter.
Therefore, you don’t need an additional faucet on your kitchen sink for operation. Instead, the unit delivers water directly to your current plumbing. Since the filter line connects to your cold water main, it only filters the incoming cold water, not the hot water from your geyser, heat pump, or gas water heater.
Ease of use is the primary advantage of a “simple system.” Instead of relying on two separate faucets to deliver water, a single tap provides your purified water supply.
- Inexpensive compared to other under sink systems.
- The unit doesn’t require the installation of a separate faucet.
- Easy to install, clip-on connectors.
- Filters all water coming in from your cold water main. Therefore, it’s not the most efficient system, as you’ll be using filtered water to clean your dishes or wash your hands as well.
- Since you’re filtering more water, the filters don’t last as long as a conventional system.
- Simple systems have a higher flow rate than conventional units. Therefore, it’s less efficient at removing all particles and contaminants from your drinking water.
Conventional Under Sink Filter
This system garners its name from its installation. Initially, under sink units were the first design available to the public, hence the name. The difference between a conventional and simple unit is that you divert the cold water main into a separate line when installing a conventional water filter.
The line runs through the system and into a permeate tank before delivering the purified water through a separate faucet that mounts to your sink. Therefore, you have two taps on your counter – one supplies unfiltered cold and hot water suitable for cleaning, while the other faucet delivers purified drinking water.
- Extended filter longevity, therefore less money spent on filter units.
- Lower flow rate means more time in the filter and improved filter efficiency.
- Easy installation and universal connection on all plumbing types.
- Installation requires a separate hole in the sink for the faucet.
- Some users may need to cut a hole in their kitchen sink.
- Lower flow rate than a simple system.
Reverse Osmosis Water Filter
RO systems differ from typical water filters in the fact that they use an additional “membrane” during the final filter stage. This membrane removes up to 99.9-percent of all particles, chemicals, pathogens, and bacteria from your drinking water.
However, RO also removes all of the minerals from the water as well. Some RO systems come with an additional filtration stage adding alkalinity, calcium, and other valuable minerals back into the water before sending it to the permeate tank for storage.
RO systems typically offer more service time compared to simple or conventional filters. The membrane tends to clog up less than traditional carbon filters. You can expect a reverse osmosis membrane to provide 2 to 3-years of service, while a carbon filter provides 6 to 12-months of use before efficiency drops dramatically. Reverse osmosis also requires higher water pressure than simple or conventional units to operate efficiently.
- Removes up to 99.9-percent of all harmful particles and contaminants.
- Eliminates heavy metals, hormones, and pharmaceuticals.
- Easy installation.
- The membrane offers less service time than conventional or simple filters.
- Slightly more expensive to maintain due to membrane costs.
- Removes all minerals from the water and requires a separate filter to reintroduce them.
