If you’re looking for a reliable water treatment system that filters all the water coming through your faucet, then an under-sink water filter may be a good investment. As their name suggests, under-sink water filters (a.k.a., under-counter filters) can fit under your kitchen sink – entirely out of sight. Not only are they unobtrusive, but they are also budget-friendly and efficient. They can even solve the constant refilling issue associated with pitcher filters. Thank goodness!

Further, under-counter water filters require low maintenance. Once installed, you won’t have to change the filters for months. That means you can banish all those pitcher filters from your life forever, and enjoy the healthy perks of crystal-clear, great-tasting filtered water without the frequent refilling problems.

But considering all those excellent benefits, you might start to wonder if under-sink water filters are a good investment compared to some of the other types of water filtering solutions on the market, such as whole-house filtering systems and others.

To satisfy your curiosity, we’ll be discussing the good, the bad, and the ugly about under-counter water filters. Hopefully, you’ll learn everything you need to make an informed buying decision when the time comes. Let’s go!

What is an under-sink water filter?

An under-sink water filter is a Point-of-Use (POU) device that works to remove many different kinds of contaminants from drinking water. POU means that the system is installed where you need access to clean water, such as at your kitchen or bathroom faucet, or anywhere you have an appliance that requires clean, filtered water. Also, under-sink water filters are in-line filters that connect directly to your waterline. The water passes through the filter before coming through your tap or other outlets. However, some under-sink filters dispense water through their own specially-installed faucet.

How do under-sink water filters work?

A typical under-sink filter system uses a straightforward delivery process. The filter receives its water through a bendable plastic tube linked to the cold-water line below the sink. This tube then sends some of the water over to the filter itself.

Once the water has passed through the filter, it is expelled via a flexible polyethylene tube and exits to you from a tap installed directly into the sink. In this way, there will never be any crossover of unfiltered water.

The continuous pressure of the system causes water to emerge from the purifying device and spurt out when the particular tap is opened. The standard hot and cold water features stay apart at the sink. Just whisky that has gone through the exclusive tap is filtered.

The Pros

  • They’re convenient and efficient: Under-sink water filters provide instant, permanent access to filtered water from a single water source. So, you won’t have to purchase a more expensive solution or refill a pitcher anymore.

  • They deliver targeted filtration: If you don’t want to waste money filtering water for your bathroom, laundry, and toilet with a whole-house filter, under-sink filters allow you to treat water at specific points in your home. After all, most families are mostly concerned with making sure that their drinking water is safe.

  • They save counter space: If you need the valuable storage space on top of your sink or counter, installing an under-sink filter will be a good choice, especially if you live in a small apartment and need all the countertop space possible.

  • Better capacity and speed: The best under-sink water filters on the market clean around 1,000 gallons of water. This means that some under-sink filters can last for a year before they need to be replaced. Moreover, because under-sink filter use water pressure to force water through the filter, their filters can be denser, so they can remove a broader range of potential contaminants.

  • No need to replace cartridges very often: When it comes to maintenance, under-sink water filters are a step-up from pitcher filters. Under-sink filters offer at least six months of filter-replacement-free operation, while filter replacement is required every two months or so for pitcher filters.

The Cons

  • Cost-wise, under-sink water filters may have a steeper price tag than pitcher filters; however, they require less frequent replacements.

  • The normal kitchen faucets offer a higher flow rate than the smaller counterparts that usually come with under-sink filters. Filling up a 16-ounce glass with some dedicated taps may take up to 20 seconds.

  • Water from a sink filter will not be as cold as the liquid from a refrigerator pitcher or emitter. It can be quite laborious for some to add ice cubes hastily to achieve their desired coldness.

  • If you need more room beneath your sink, then there may be better choices than an under-sink water filter. This is especially relevant when you require maximized space in your kitchen area.

  • Most likely, it will take a plumber to install the filter: To make things simpler and quicker, utilizing the service of an accredited plumber in your location is recommended. If you do not possess any plumbing background, enlisting an experienced person may be the best way to put your filter in.

What differentiates under-sink water filters from other forms of filtering structures accessible in the marketplace?

under sink vs normal water filter

Under-sink Water Filters vs. Water Pitcher Filters

Pitcher filters offer a variety of advantages, including the increased flavor of the water and the ability to quickly and efficiently obtain cold, filtered drinking water from the refrigerator. Furthermore, these are ideal for households with already excellent water sources as they likely won’t be able to fix severe quality or taste problems.

Still, a pitcher filter might not be the optimum or cost-effective approach if there is considerable demand for drinking water in your home. An under-sink system offering quick access to high quality drinking water exclusively from the faucet or thereabouts may be worth considering in such a case.

Compared to water pitcher filters, under-counter filters produce a higher quality and better-tasting water that can serve the needs of an entire household. Not to mention, users will appreciate its convenience and the effective filtration that under-sink water filters can provide.

Under-sink Water Filters vs. Countertop Water Filters

It is apparent that under-sink and countertop water filters are the two most common types utilized in homes. Nevertheless, in terms of convenience and effectiveness, it appears that under-sink filters tend to be the favored choice for many house dwellers – we can certainly appreciate why.

Countertop filters provide more utility than under-sink models, as they do not need plumbing or specialized faucets and are highly transportable. This makes them optimal for homeowners in small apartments, renters, university students, and others who desire a clear water filter. However, compared to the alternative of sinking filters, countertop versions typically come with fewer filtration system options and levels of contaminant removal. Additionally, they may take up valuable kitchen space on the countertops. Countertop filters mostly utilize activated carbon and ceramic media for filtration.

In comparison, under-sink filters have a range of filter media integrated into one system, such as reverse osmosis and activated carbon filter. Furthermore, these can offer numerous filter cartridges with micron ratings for superior water output, enhanced ability to remove contaminants, and so forth.

The intricate characteristics of under-sink water filters render them as more suitable than countertop ones as they can offer an even more thorough filtration.

Under-sink Water Filters vs. Whole-House Water Filters

Whole-house water filters tend to be the most expensive of all the filtration options. However, they are known for treating the entire house’s water access point at entry (POE) or the main water line. This gives all inhabitants fresh drinking waters right away. Alternatively, an under-sink filter supervises water at its source of use and promises immediate availability of pure liquid wherever it is needed.

A whole-house filtration system can be a great asset, although it may only sometimes be necessary also to implement an under-sink filter. Usually, both setups are beneficial since the water used for cleaning and laundry does not need to be as pure as intended for drinking.

Various whole-house filters are available, so the best choice for you is determined by your water source and the type of filtration needed. If your water comes from a private well, a whole-house filter specifically designed for well water is necessary. Moreover, filter systems contain softening mechanisms to get rid of hardness minerals in the water and those with UV purification technology to eliminate bacteria and other dangerous microorganisms.

One definitive point is that under-sink water filters and whole-house systems both serve the same goal and can be very beneficial, depending on your particular situation and what type of filtration you are looking for.

So, should I invest in an under-sink water filter?

It is difficult to answer that question in a simple way. We advise that prior to investing in an under-sink water filter, conducting a water test should be the first step. A home water testing kit would be the most efficient approach. Moreover, it is possible to obtain FREE Water Testing of your Tap water by getting in touch with us.

The next step is choosing whether you want to filter all the water flowing into your residence, or just certain locations like the kitchen or bathroom. If it’s the whole house that needs filtration, then you’ll need a complete system. On the other hand, if you only require special areas to be treated, opting for a dedicated unit is recommended. But before rushing out or browsing online shops for purchase, consider these factors so you acquire the device best suited to your requirements:

  • When buying an under-sink water filter, bear in mind the lifetime of the filters. They may have a short shelf life with some lasting for no more than 3 months whereas others will hold up for 6 to 12 months.

  • To find the right system size, first, measure the area in which it will be placed and take into consideration the potential difficulty in maneuvering around it to change filters. Small under-sink water filters normally occupy little space, while larger multi-stage filtration systems might be a bit too bulky for some spaces.

  • The filtration ability of a system is reflective of the quantity of unwanted contaminants that can be removed from your drinking water. Thus, it is essential to read through the product description for each unit in order to determine whether the pollutants listed on your water test results can be eliminated, alongside other hazardous materials that might obstruct the quality of your health.

  • It is essential to determine whether the system has a built-in tap or not: certain undersink water filters will only function with special taps. Setting up such a filter may take extra effort, although some professionals are convinced that connected faucets give the purest water overall.

  • The pressure generated by the system: Beneath the sink based water purifiers generally do not create a strong streaming water pressure. Consequently, the refill rate of a glass is slower than usual. Nonetheless, this simply implies that all the stages of filtration are effective. As they say: Patience result in good things.

  • When it comes to items such as under-sink water filters, most home appliances will feature some form of a manufacturer’s warranty. In general, the longer the warranty duration, typically the higher the product quality level. Before buying an under-sink filter or any other household device, be sure to store all receipts and other proof of purchase in a secure area if you want to take advantage of it later.

  • Your financial plan: You can get sensible under-sink water filters at a cost of less than $50. To rent, we provide an under sink water filter with a Reverse Osmosis filter and Bottleless water cooler for only $35 per month. If you would prefer to buy, our price plan offers a scheme for $599 – look it up for further info.

What water filter system do you suggest for under the sink?

Aqua Chill offers two under-sink filters: the Reverse Osmosis Drinking Water System and the Carbon Water Filter. This convenient point-of-use (POU) filtration systems can be installed beneath most kitchen sinks and are estimated to generate 75 gallons of pure water daily. Thanks to these compact fits, contaminants like fluoride, aluminum, arsenic, lead, chlorine byproducts etc. can be removed from your drinking water with ease.

When it comes to filtering, four stages of Reverse Osmosis and Carbon filtration are used for water filtration.

  • Stage 1 (Sediment Filtration): Firstly, the system filters out coarse impurities that may be found in your water.

 

  • Stage 2 (Carbon Filtration): Subsequently, the carbon filter dislodges chlorine, chloramine, herbicides, pesticides and other hazardous matter from the water.

 

  • Stage 3 – Thin Film Composite Membrane: Through utilizing a TFC process small particles such as bacteria, pharmaceuticals, etc are eradicated from the drinking water.

 

  • Stage 4 (Carbon Filtration): Ultimately, the carbon filter accomplishes the treatment phase by eliminating any remaining minute particles that escaped previous steps.

On top of that, we offer a one year warranty against defects on all covered parts and a six-month money-back guarantee. We recommend replacing the sediment filter and the carbon filters every 9-12 months, and the reverse osmosis membrane every 5+ years.

Here’s the icing on the cake: If you cannot afford to purchase any of the filters in full, we also provide rental service with Free installation and Free Service. All we need is a few pieces of information to make a real-time decision. Plus, there are no hidden fees. We’ll tell you upfront exactly how much you owe.
