Easy to Install: The installation seems tricky in most of the filters. So, it becomes difficult for us to replace filters. But this filter has a trouble-free installation. You just need to exchange the filters and then flush it for about 5mins for better results. Don’t forget to close the valve before replacing it. And it’s just as simple as that!

Activated Carbon: Granular carbon prevents the amalgamation of carbon particles. Granular ones are made with either coal or coconut shells which is why they are sometimes called “Charcoal” filters. The activated carbon removes odor and controls pesticides.

Wrench Included: Installation made easier! The packaging includes a stiff wrench which is really very useful. The KW1 water filters do not bear any tools in the packaging. But this filter has a wrench which is for removing sump and garden fittings. This wrench also helps to deal with tight nuts or bolts.

No Contamination: This replacement filter acts like the original one. It controls pesticides in water. The inner covering has no harmful chemicals like BPA or leads, or any other chemicals. So, no extra contamination will occur due to the filter alone. Its activated carbon controls carbon amalgamation as well.

American Water Solutions (CCI-10-CLW)

Reduces Chlorine: Water becomes impure real quick. These impurities may include chlorine, dust, rust, etc. Chlorine is not something that we should consume with water. Hence, this filter reduces the amount of chlorine and makes the water drinkable. The filter is capable of reducing other sediments as well. Interestingly, it also reduces calcium, iron, lead and other heavy metals, which is indeed a great plus of this filter.

You can trust wholly on this purifier as it’s NSF certified. The brand has been working for many years to better all with all the necessary proofs and certificates.

Durable Material: The purifier is made of polypropylene. Polypropylene is really tough and scratch-resistant. It has a semi-crystalline nature which makes it flexible and tough. The filter won’t get damaged easily due to the contact of different chemicals as PP is chemical resistant.

Reduces Pesticides: Pesticides being in the drinking water is a common phenomenon. Especially in agricultural lands, pesticides get into the water. This filter has an RO unit to solve this problem as well. The reverse osmosis system reduces more or less 99% pesticide and makes the water healthy.

Multi-Layered: Three-layered filters are hard to find. Surprisingly, this purifier is made of three layers with different widths (inner one 5micron, middle one is 7 while the outer one is 10micron). The layers capture the impurities precisely and keep your family away from diseases.

Capacity: The longevity depends on the use of a filter. The water demand indicates the use of a filter. However, this purifier has a capacity of 13000gallons which isn’t similar to the KW1 water filter. KW1 does not have sufficient capacity, in my opinion.

Flow Rate: The strainer is true to its job. It can purify water in a jiffy. The flow rate is sufficient as it’s 2.5-5GPM on average. Many of you can say that the flow rate isn’t as expected. That’s because the rate highly depends on the region from where the water is coming. Other than that, the filter is very swift.

  • Durable
  • Multiple layers ensure pure water
  • Reduces pesticides
  • High capacity
  • Do not work well in case of well water

4. SimPure Carbon Block Filter Replacement

Be it an under-sink or a countertop filter, SimPure can fit in all seamlessly! It’s a carbon-made filter with a huge capacity and many other amazing features.

Coconut Shell: The filter has activated carbon with a coconut shell. The carbon is covered with PP, which is food grade. The covering is a non-shedding one. The activated carbon does not let any carbon particles contaminate the purified water. The carbon block reduces about 98% of chlorine.

Improve Taste: Pure water tastes healthier and tastier. This purifier introduces you to the real taste of water through its high purifying techniques. Moreover, the filter disrupts the entrance of harmful chemicals and heavy metals like lead, cysts, chlorine, and many more.

Compatible: KW1 filters do not easily fit in most of the brands. You can consider this filter as an alternative as it has great compatibility. Starting from countertop filters to under-sink ones, this filter fits in all types. This one’s suitable for any 10-inch housing and cooperates with the brand, including Whirlpool, Culligan, etc.

Filter Life: You’ll be glad to know about the capacity and lifetime of this one. 15000gallons is its unbelievable capacity! You can use it for about 3-6 months at ease. It’s too good for personal use. Moreover, it’s a pack of four which is really fantastic.

BPA-Free: BPA is used to make various plastic materials as it’s inexpensive. But it’s not at all good for our health. This filter is BPA free which means water will also be BPA-free. So, no chances are there for the water to get contaminated. So, to keep yourself healthy, there’s no alternative to this one.

  • BPA free
  • High compatibility
  • Activated carbon reduces chlorine

Why Would you Need to Analyze the Limitations of the Reverse Osmosis unit?

Every object has its advantages and disadvantages. So when you’re about to use a particular object, you need to be aware of its advantages and disadvantages.

For a healthy life, we need to ensure a suitable water filter first. RO filters provide maximum pure water. These filters are perfect for dealing with hard water. The semi-permeable membrane used in the RO unit strains all the chemicals and impurities precisely.

But certainly, there are some limitations. For example, RO filters can’t deal with microorganisms. Moreover, it removes essential minerals from water that can cause a mineral deficiency. In addition, it takes more time to purify water and uses more electricity. Apart from these, a RO filter is a perfect one to have. However, these advantages are negligible, and so most people prefer RO filters.

So, you need to know all the advantages and shortcomings to choose the suitable one for yourself.

What to Look at While Selecting a KW1 Water Filter Alternative?

Every equipment or appliance has both advantages and disadvantages. But when the disadvantages are not negligible, then we feel the need to look for an alternative. For example, KW1 filters have such disadvantages. But looking for an alternative seems really tough. So, here are some key points to help you with that:

  • Compatibility: As you know, KW1 filters aren’t compatible at all. No other brands will fit in it, which is problematic. So, the filters which are compatible with most of the brands are to be chosen. Otherwise, you’ll face difficulty every time you replace the filter.
  • Time-Saving: The slow filters use more electricity as well. Also, you need to wait for a long. Time-saving filters are essential for our day to day life, and it also saves much electricity. You need to get a time-saving one for yourself to have a hassle-free morning.
  • Easy Installation Process: While replacing a filter, we often do not know the process. Some filters have a tricky installation process, and our guesswork doesn’t come in any use. At times, we end up breaking any equipment. While selecting an alternative, be aware of the installation process. Select the ones which seem convenient to you.
  • Zero Contamination: Water gets contaminated even if the filter works perfectly. But why? That’s because the inner portion of the filter isn’t food grade or contains heavy metals. These contaminate even the filtered water. So, do check the materials with which the filter is made of. Most importantly, these filters are highly efficient in removing coliform and other pathogenic bacteria.
  • Filter Life: The lifespan of a filter depends on the source of water at times. These matter a lot, like if it’s feed-water or river water. But in general, you should prefer the filters which have 13000-15000gallons capacity. This is the standard range, and a filterless than that will be troublesome.
