Top 10 Dishwasher Water Filters

Dishwashers are no longer just about putting in dirty dishes and taking them out sparkling clean.

The quality of the water being used in the dishwasher can determine the cleanliness of the dishes, the amount of electricity and soap used, and even the integrity of your machine.

Water filters fitted in the tap-water system or the dishwasher remove minerals, metals, and chemicals from water, reduce the deposit of minerals inside the machine, and prevent clogging and the accumulation of scale inside the dishwasher.

Installing a water filter in your dishwasher improves how your dishes are washed and preserves the quality of your machine.

Below are some of the best dishwasher water filters you can buy.

1.       WaterSentinel WSD-1 Scale and Lime Guard Dishwasher Filter

This filter is perfect for both residential and commercial use.


  • It removes chlorine, tastes, and odors in water.
  • It cleans the heating element hence increasing the efficiency of the machine.
  • It prevents the forming of lime and scale on dishware.

Is your dishwasher consuming more soap than normal and you have no idea why? It is probably because you are using hard water which is rich in minerals and metals that make it hard for soap to lather. My last dishwasher broke down after the metal parts inside it were corroded and compromised by the metal and mineral deposits from the tap water. The damage was so severe that I had to replace the whole machine. The plumber advised me to invest in a water filter which would prevent all those contaminants from ruining my dishwasher or my dishes. Since I began using this filter my dishes come out looking sparkly and I do not even use as much soap as before. It is great and installing it is pretty easy so you can do it yourself. If you use well water like me you can buy a sediment filter and install just before the water filter so you can prolong the life of your filter.


This water filter is perfect for commercial residential water filtration and ideal for water heaters and boilers.


  • It has a scale inhibitor which fights hard water and cloudy residue on glassware.
  • It reduces the accumulation of mineral deposits in the dishwasher.
  • It is extra convenient since it comes with all its installation components.

I had a problem with the pipes in my dishwasher clogging and preventing the free flow of water inside it when washing the dishes. My machine would make a lot of noise because the water came out in spurts and sometimes it left green slimy residue on the dishes and in the trays. I kept calling the plumber to fix my machine every two weeks and he advised me to get a water filter because the water was causing scales to build up inside the pipes and if I did nothing about it I would have to replace the whole thing. I bought the filter and installed it myself using the instruction sheet in the package. It`s been two months since I had a plumber in my house and my dishwasher is as good as new. The best part is that it comes with several spare filters and a hose so you can replace them at the bottom of the unit several times before buying a new one. It is worth every dollar.

3.       BLUONICS Dual Whole House Water Filter Purifier

This water filter is suitable for the whole-house cold water system.


  • It has carbon block and sediment filters that remove sediment, chlorine, odors, chemicals, and contaminants.
  • it effectively removes impurities from tap water.
  • It comes complete with filter cartridges, a wall bracket, screws and a housing wrench hence you do not need to call a plumber.

The water filter is great and it is especially convenient that you can see the filters through the clear plastic cartridges so you can change them out when they get dirty. It is not a large filter so you might want to put a pressure relief in the piping to avoid breaking it or simply use it for a water system that does not have heavy water flow.  It is ideal for cleaning your house water supply so using it for construction or other heavy work where the water is more contaminated will surely overwhelm it and you probably won’t get the desired quality of water. I was afraid that using a filter would leave the tap water tasteless but it`s pretty good. My kids don’t fuss about buying bottled water anymore because they just get it straight from the kitchen sink. I would recommend it to a friend.

4.       Hansing Under Sink Water Filter

This water filter is perfect for commercial use because of its high flow water filtration system and ultra-high water capacity.


  • It removes chlorine, chloramine, lead and other heavy metals.
  • It gets rid of bad taste and odors.
  • It prevents the accumulation of scale and mineral deposits inside your machine.

I started shopping for a water filter after the iron present in our house water started affecting my baby’s skin. The water had this metallic smell and would leave a ring of what looked like dirt in the kettle and it was so hard to come off. I bought the Hansing filter from Amazon mostly because it was cheaper than the rest but it has proven to be a good buy. I installed it myself with a Teflon tape, an adjustable wrench and a drill to mount the bracket on the wall. Now the water coming into my kitchen is so clean I can drink it from the tap without having to boil it and we do not have metal in our water anymore. You may need to buy a pressure relief or install the filter where the water flow is not too high because high water pressure is bound to break it. If your water has a higher pollutant level compared to normal municipal water, you might need to install a sediment filter for better results and to avoid blocking the filter. I am very happy with the results.

5.       KleenWater Dishwasher Water Filter

It is perfect for households that receive hard water.


  • It contains a resin softener that softens hard water.
  • It gets rid of the cloudy build up on glass utensils.
  • It reduces mineral deposits inside pipes and other water passages in the machine.

I installed this filter after the hard water in my home ruined all my dishes, silverware, and glasses (the water in my city is milky white).

There were brown stains on my dishes that did not come off even after scrubbing and my glasses had turned from sparkling to a white film appearance. I had to wash my dishes by hand after putting them in the dishwasher. This filter has removed all those ugly stains and I do not have to be embarrassed when I’m hosting. It might be better to get a plumber to install it for you if you aren’t handy with tools because installation is a bit complicated. The filter works great and my new set of dishes is as sparkly as when I bought it. I had to buy a new dishwasher though because the metal parts of mine had begun to rust because of all the mineral deposits in there so it might be a great idea to invest in a water filter to avoid more expenses in the long run. This filter is highly recommended.

6.       Woder WD-S-8K Water Filter

It is more suitable for refrigerators and ice makers but works well with dishwashers and tap systems too.


  • It gets rid of chlorine, lead, and other contaminants.
  • It removes turbidity.
  • It removes bad odor and taste from water.

Do your dishes smell foul even though they seem clean or are just out of the washing machine? That was my problem too for a long time before I discovered that a good filter could do away with it. My friends would complain that my water tasted like there were frogs in it but now the aftertaste is completely gone. The Woder filter has eliminated the unpleasant smell and taste in my water and I can confidently use it for cooking, cleaning, and drinking. The filter also softens the water going into my dishwasher so I don’t have to worry about the pipes clogging. The fittings on the filter are pretty fragile so it would be wise to have a pressure relief fitted if your water system has high a high water flow. It is made ideally for a refrigerator so it would be best to have a plumber install it for you if it is going in your dishwasher.

7.       Woder WD-10K-DC Ultra High Capacity Under Sink Water Filtration System

It is most suitable for water that has been disinfected properly before use.


  • It eliminates lead, heavy metals, chlorine, chromium 6, and mercury.
  • It removes turbidity.
  • It is high quality and long-lasting.

This filter completely transformed my dish-washing experience. I bought it because I was seeing mineral deposits on my plates and glasses and my dishwasher had started to smell foul. I had to do some research into filters because I’ve never heard of anyone using them but now that I have one I cannot stop telling people to buy them too. I admit that it is a bit pricey but it`s worth every penny. My utensils are back to being sparkly and I am saving big on soap and electricity. I also had one installed in the main water system of the house because the water here is full of impurities and they are always clogging my taps and showerheads. I had my house water tested and it does not have traces of iron like before so I am really happy about that. The fittings on it are very strong and they fit into my pipes perfectly so there is hardly ever any leaking. I will buy it again.

8.       Frizzlife Under Sink Water Filter System

It is great for filtering drinking water but can also be fitted into your dishwasher or refrigerator.


  • It removes lead, chlorine, bad taste and odor from water.
  • It has a two-stage advanced purifier that removes the contaminants and retains essential minerals.
  • It is very easy to install without the help of a plumber.

I own a restaurant and have been struggling with contaminated municipal water for the longest time. I had to invest in a filtration system because my workers and customers were complaining about foul-smelling water that had a metallic aftertaste. Everyone would comment that the food was great but the water was awful and I wasn’t having it. Having used more than five different filters in the past year I can confidently tell you that this is the best water filter out there. I noticed that other filters filtered out all the minerals in the water. This is not necessarily a bad thing if you are using it for your dishwasher but when it comes to drinking water I prefer mine with a more natural taste. After using other filters I ended up having dead water which is tasteless water and most people aren’t comfortable drinking it. Frizzlife gives me clean drinking water and I couldn’t ask for more. It is also pretty easy to install by just following the instructions on the package if you want to use it for your home water but you’ll need to hire a plumber if you want it installed in a big establishment. This is my newly found holy grail.

9.       Woder WD-4K-Ultra High Capacity Under Sink Water Filter

It is great for both residential and industrial purposes because of its ultra high capacity features.


  • It removes lead, mercury, heavy metals, chromium 6, carcinogens, and other contaminants.
  • It removes turbidity, unpleasant odor, and taste.
  • It supports up to 4,000 gallons of water and is very long-lasting.

Having an expensive dishwasher that does not give you the expected results is depressing. I bought this water filter after coming across a lot of positive reviews on Amazon concerning it. The best feature for me in this filter has to be the direct connect fittings that make it super easy to fit into your dishwasher, I installed it in less than 10 minutes. This may depend on the dishwasher brand you use so maybe it is best to inquire before buying. I first bought it when I was using well water for all my household activities and it did not last long. When I moved houses, I bought it again but was advised to use it together with a sediment filter to avoid having the residue mostly food in well water clogging the filter. My dishwasher now takes less time to complete one cycle and I have not found any stains or residue in my dishes since I started using it. It would have been great to use it for my hot water system but it is specifically made for cold water so that would be ruining it. Its fittings are really strong and I have a feeling I`ll be using it for a long time. I would buy it again.

10.  KleenWater Hot Water Filter

It is ideal for both commercial and residential dishwasher water filtration.


  • It provides three layers of filtration that trap large particles, smaller ones, and even the finest particles.
  • It entraps sediment.
  • It has a grooved surface which increases the filter cartridge surface area, enabling it to last longer.

I started shopping for a dishwasher water filter when I started to notice a musty smell on my utensils and stains on them that wouldn’t come off. My glasses and silverware had completely lost their shine and I had to wash them again afterward to restore some semblance of cleanliness to them. A friend of mine who has used the KleenWater filter before recommended it and I couldn’t be more grateful. This filter works great. I had to buy new pipes for my dishwasher because the old ones had been clogged by scales and lime from hard water so you might want to get ahead of things by getting a filter as soon as possible. I had no idea of using hard water for dish-washing could increase the amount of time and electricity you use in a wash cycle. Now I have saved on both electricity and the extra water I would use to wash my dishes a second time. The filter is mainly suited for removing particles from the water so if you have really hard water you might consider a more suitable option. The fact that you can fit it in both tap water and hot water systems is also a huge plus. It is really easy to install on your own but I had to call in a plumber because I had a lot of parts to install including fitting it into the sink so it would filter my drinking water too. I would recommend this to my friends.

Choosing a Dishwasher That Works for You

 Although shopping for a dishwasher may be exciting, settling for the wrong one can leave you counting your losses if it doesn’t fit your kitchen, washes few dishes, or leaves food on the dishes.

This is why it is necessary to consider the options below before picking out a dishwasher for your home.

  • Integrated or freestanding

Integrated dishwashers are made to be integrated into built-in kitchens. Its displays are normally hidden inside the cabinet so you have to keep opening the door to check what time you have left.

Freestanding dishwashers are the most common so finding one that suits your budget is easy. They are portable so you can easily pull them out for maintenance or if you are moving homes.

  • Slimline, full-sized or compact

Slimline dishwashers are narrow and taller than other dishwashers so they are a perfect fit for a small kitchen but they aren’t capable of washing as many dishes at a time as others.

Full-sized dishwashers can wash more than a hundred items at once, therefore, saving both water and electricity. They are bigger than the slimline ones hence suitable for large kitchen space.

Compact dishwashers are efficient for washing a few dishes. They are small and can be placed on a table or counter. They are quite expensive but use less electricity compared to other dishwashers.

  • Features and dishwasher programs

Some dishwashers have adjustable racks that allow you to fit in more dishes.

Some dishwashers have float switches to detect water at the base of the machine and stop it from filling more and aqua stops to prevent flooding in case the hose leaks.

Most dishwashers have a child safety lock to prevent interference with the machine settings when it is in use.

Although the use of filters for dishwashers is not a popular practice at the moment, it is something you ought the consider especially if you have hard water in your area and are looking to prolong the life of your machine together with the quality of your dishes and silverware.

Some filters are best suited for other appliances and trying to use them for your dishwasher could flood your kitchen and prove to be a waste of time and money so be sure to inquire if the fittings of the water filter you want can be modified.

An expensive filter does not necessarily guarantee that you will be getting the best quality so you might want to look for one that fits your budget, is compatible with your dishwasher, and solves the problem that you have.

It is best to seek the services of a plumber while making water filter installations to avoid damaging your filter or your dishwasher especially because most of them require one to have some knowledge when it comes to handling tools.
