If you are looking for water filter systems, you have probably understood the need for such products and the benefits that they can bring. However, in order to find the right product for your needs, it is important to base your decision on accurate information. Despite the fact that water is relatively clean when it leaves municipal water filtering institutions, by the time it reaches our homes, it gathers numerous contaminants from the old pipes that it uses to travel. Furthermore, even if municipally filtered water is not highly dangerous for our health, it is still far from being pure. Over 85% of the homes in the USA have hard tap water. Hard water contains a below-average level of minerals. Hard water is safe to drink but is very destructive for appliances, it clogs pipes, reduces the cleaning abilities of detergents, and so on. Other than minerals, tap water also contains a lot of toxins, gathered either from pipes or created as byproducts of the municipal filtration process. This being said, you need to test your water and determine your needs before investing in a water filter system. Today, we will present you with some Whirlpool Undersink Filters. Undersink filtration systems are very convenient because they don’t use any of your useful kitchen space.

Whirlpool WHER25 Reverse Osmosis (RO) Filtration System

The WHEUFF filter, also known as Whirlpool® Main Faucet Filtration System is one of the most popular under-sink filters. The good reviews were based on its efficiency but also on its easy installation process. According to your plumbing skills, it will take between 10-20 minutes to install this filter under your sink. The Whirlpool Main Faucet Filtration System is NSF certified and it is designed in order to reduce the unpleasant taste and odor of chlorine but also to reduce cysts and sediment. The product has the following dimensions: D 3 in., W 4 in., and H 14.5 in. As you can see, it is very small so it takes very little space under the sink. The filter is designed to last for about 6 months. This means that one filter can handle approximately 2,000 gallons before needing to be replaced. The replacement filters cost about $20 and are very easy to install. As we mentioned above, it is essential to do a water analysis of your water and determine your needs in order to know what type of water filter you need to buy. If your water contains heavy traces of pharmaceuticals, lead, chemicals or micro-organisms, you might want to check out another water filter because this one is not equipped to handle such water contaminants. However, if your water is reasonably clean and your main concern are sediments and chlorine, this filter will work just fine.

If the previous filter was too basic for your needs, you might find the following one to be more useful as it is definitely a step one from a basic filter. Whirlpool Dual Stage Filtration System, also known as the WHED20 water filter is designed for municipal and private well water supplies. Aside from sediment and the unpleasant taste and odor of chlorine, this filtration system also eliminates cysts, lead, VOCc and MTBE. VOCs (Volatile Organic Contaminants) are very dangerous as they can lead to numerous health problems. In order to ensure an optimal efficiency at all times, this water filter system features an EZ-Change indicator light which lets you know when the filter is no longer useful and needs to be replaced. This system can fit under most kitchen sinks and aside from the filters and hardware, also comes with a decorative faucet. The filters can literally be changed in just a few seconds without any trouble or mess. The filters are designed to last for 6 months or for 2,000 gallons of water. The system has the following dimensions: D 4 1/2 in., W 14 in. and H 13 1/2 in. Last but not least, this water filtration system is NSF certified, it costs $99.99 and comes with a one year limited warranty (which does not include the filter cartridges).


Whirlpool under sink filters can satisfy a wide range of filter needs. The Reverse Osmosis system is perhaps the most complex filtration system. For those of you who are unfamiliar with this term, reverse osmosis is a process that involves forcing the water through a semipermeable membrane that traps most of the water contaminants. This system is used by many bottled water distributors. This particular system designed by Whirlpool which is also known as WHER25 is designed for municipal and private well water supplies. The water delivered by this system does not just taste better, but it is a lot safer to drink. Furthermore, it only costs a fraction of the cost of bottled water. The most common contaminants which can be trapped by this system include arsenic, copper, Cysts of lead, radium, Cryptosporidium, Giardia cysts, and industrial discharge turbidity. Needless to say, the unpleasant taste and odor of chlorine will be a long-lost memory once you start using this filtration system. During numerous tests, the membrane of this system has also proven very useful in trapping dissolved solids such as nitrites, chromium, sodium, and magnesium. The system also features an indicator light that does not just notify you when the filter needs to be changed but also displays the water quality. This product comes with a one-year limited warranty which does not extend to the filter replacement cartridges.

While water filters are rather common, water purifiers are newer on the market and most people haven’t heard about them. The difference between a filter and a purifier is the fact that filters are designed to prevent contaminants from entering a water filter while purifiers remove contaminants from a water system. This particular purifier, also known as Whirlpool WHEMB40 is designed for municipal or private well water supplies. The great thing about it is that it does not waste any water. It is considered the ultimate water filtration system as it exceeds all the EPA standards for removal of cysts (99.95%), bacteria (99,9999%) or viruses (99,99%). It is also fully certified to remove chemicals, sediment, chlorine, and lead. This product comes with filters, hardware, and a decorative faucet. It fits under most sinks and the filters are very easy to replace. It has a reminder light which lets you know when the filter needs to be replaced. The system costs $232.99. The price might seem a little spicy, but if you value the well being of your family, you won’t make any compromises when it comes to water purity. Nevertheless, this is only useful if your water has proven to contain high levels of dangerous contaminants.

Conclusion: Whirlpool Undersink Filters


As you can see, water filtration systems come in a wide variety of models and at different prices. Choosing a filter without testing the quality of your water would be a waste of money as you wouldn’t know what type of contaminants your water contains. If your water only contains chlorine, then the only thing you need is a basic filter whereas if your water contains dangerous contaminants, you will need a highly efficient purifier.
