Every home needs a dishwasher water filter.

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.

They also reduce the deposit of minerals inside the machine and prevent clogging and 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 Scale & Lime Guard Dishwasher Filter

Scale & Lime Guard Dishwasher FilterThis filter is perfect for both residential and commercial use.

Is your dishwasher consuming more soap than normal and you have no idea why?

It’s probably because you’re using hard water which is rich in minerals and metals that make it hard for soap to lather.

One customer said that his 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 he had to replace the whole machine.

The plumber advised him to invest in a water filter that would prevent all those contaminants from ruining his dishwasher or his dishes.

Since he began using this filter, his dishes come out looking sparkly and he doesn’t even use as much soap as before.

It’s great and installing it is pretty easy so you can do it yourself.

If you use well water, you can buy a sediment filter and install it just before the water filter so you can prolong the life of your filter.

Pros & Benefits:

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


2. 3M Aqua-Pure Whole House Inline Water System

Whole House Inline Water SystemThis water filter is perfect for commercial residential water filtration and ideal for water heaters and boilers.

A customer said that he had a problem with the pipes in his dishwasher clogging and preventing the free flow of water inside it when washing the dishes.

His 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.

He kept calling the plumber to fix his machine every two weeks.

The plumber advised him to get a water filter because the water was causing scales to build up inside the pipes and if he does nothing about it, he would have to replace the whole thing.

So, he bought the filter and installed it by himself using the instruction sheet in the package.

It’s been two months since he had a plumber in his house and his 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’s worth every dollar.

Pros & Benefits:

  • 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’s extra convenient since it comes with all its installation components


3. BLUONICS Dual Whole House Water Filter Purifier

Dual Whole House Water Filter PurifierThis water filter is suitable for the whole house cold water system.

The water filter is great and it’s especially convenient that you can see the filters through the clear plastic cartridges, so you can change them out when they get dirty.

It’s 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’s 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.

A customer said that he was afraid that using a filter would leave the tap water tasteless but it’s pretty good.

His kids don’t fuss about buying bottled water anymore because they just get it straight from the kitchen sink.

He said that he would recommend it to a friend.

Pros & Benefits:

  • 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 don’t need to call a plumber


4. Hansing Under Sink Water Filter

Under Sink Water FilterThis water filter is perfect for commercial use because of its high flow water filtration system and ultra-high water capacity.

A customer said that he started shopping for a water filter after the iron present in his house water started affecting his 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.

He bought the Hansing filter from Amazon mostly because it was cheaper than the rest, but it has proven to be a good buy.

He installed it by himself with a Teflon tape, an adjustable wrench, and a drill to mount the bracket on the wall.

Now, the water coming into his kitchen is so clean that he can drink it from the tap without having to boil it.

He doesn’t 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 the 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 to avoid blocking the filter.

He said that he’s very happy with the results.

Pros & Benefits:

  • 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

He had to wash his dishes by hand after putting them in the dishwasher.

This filter has removed all those ugly stains and he doesn’t have to be embarrassed when he’s hosting guests.

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 the new set of dishes is as sparkly as when bought.

He had to buy a new dishwasher though because the metal parts had begun to rust because of all the mineral deposits in there.

That was the problem of one customer for a long time before he discovered that a good filter could do away with it.

His friends would complain that his 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 the water and he can confidently use it for cooking, cleaning, and drinking.

The filter also softens the water going into his dishwasher so he doesn’t have to worry about the pipes clogging.

He admits that it’s a bit pricey but it’s worth every penny.

His utensils are back to being sparkly and he’s saving big on soap and electricity.

He had to invest in a filtration system because his 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.

Having used more than five different filters in the past year, he can confidently tell that this is the best water filter out there.

He noticed that other filters filtered out all the minerals in the water.

This is not necessarily a bad thing if you’re using it for your dishwasher, but when it comes to drinking water, he prefers one with a more natural taste.

After using other filters, he ended up having dead water which is tasteless water and most people aren’t comfortable drinking it.

Frizzlife gives him clean drinking water and he couldn’t ask for more.

The best feature for him in this filter has to be the direct connect fittings that make it super easy to fit into your dishwasher.

He installed it in less than 10 minutes.

This may depend on the dishwasher brand you use so maybe it’s best to inquire before buying.

He first bought it when he was using well water for all the household activities and it did not last long.

When he moved houses, he 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.

His dishwasher now takes less time to complete one cycle and he hasn’t found any stains or residue in his dishes since I started using it.

It would have been great to use it for his hot water system but it’s specifically made for cold water so that would be ruining it.

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’s 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’re portable so you can easily pull them out for maintenance or if you’re 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’re bigger than the slimline ones, hence suitable for large kitchen space.

Compact dishwashers are efficient for washing a few dishes.

They’re small and can be placed on a table or counter.

They’re quite expensive but use less electricity compared to other dishwashers.

Features & 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.

Aqua stops prevent flooding in case of hose leaks.

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

Final Thoughts

Although the use of filters for dishwashers is not a popular practice at the moment, it’s something you must consider.

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, buying a dishwasher water filter can help.

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.

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