Springwell CF1 Whole House Water Filter System Review

It is easy to believe that the city water that flows through your taps is clean and safe to drink. Often, this is not the case, and you actually need a filter system to remove invisible contaminants in the water. In this Springwell water filter review, you will find the advantages of having a water filter system and why the Springwell filter is a great option for your home.

Why Do You Need a Filter System?

Many cities work hard to clean up the water as much as possible. However, they also miss conducting essential tests which detect imperceptible contaminants in the water. These contaminants, such as chlorine, bacteria, and even lead, can leave the water with an unpleasant taste or smell.

A water filter helps filter out these contaminants, ensuring that your water has a good taste and is safe to consume. A water filter system is also more cost-effective than buying bottled water.

Springwell has top-notch filtration systems that are made with brilliantly set-up components designed to powerfully eliminate contaminants. Springwell Whole House Water Filter System is one of the brand’s most popular filters suitable for decontaminated water supply in the whole house.

The water comes in different model sizes, CF1, CF4, and CF+, all of which can treat up to a million gallons of water. Each of these sizes caters to homes with varying sizes or a different number of bathrooms, and they can all last for up to ten years, depending on the size of the family.

To put things in perspective, the Springwell Whole House Water Filter System can process up to a million gallons of water before there’s a significant drop in performance. This shows how durable the filter can be under normal usage.

As mentioned earlier, there are three model sizes. Most small houses (1-3 bathrooms) would do just fine with the CF1 model. Medium to large houses with around 4-6 bathrooms will do better with the CF4. However, houses with 7 bathrooms or more need the CF+.

The Springwell Whole House Water Filter System is uniquely designed to prevent the loss of water pressure. Unlike with many other filter systems, your shower pressure will not be slowed down by the filtration process. This filter system uses a 4-step filtration system that thoroughly gets rid of chlorine, pesticides, sediments, heavy metals, and other hazardous chemicals.

How It Works

As we said earlier, the Springwell Water Filter filters water in four steps. The first step sees the filter pass the water through the KDF process media. This media removes various contaminants, especially chlorine and soluble heavy metals, by chemically converting them. Typically, the contaminants are converted to non-harmful forms or insoluble forms.

For instance, chlorine is converted to chloride ions, which are soluble and harmless. In fact, the chloride ions may contribute to the body’s chloride needs.

The second step uses a catalytic carbon media to remove contaminants from water through a process called adsorption. The media generally removes organic impurities such as herbicides, VOCs, and pesticides. Removing organic impurities should also take care of smell to a large extent.

No process is truly 100% efficient. So, for thoroughness, the second step also removes contaminants like chlorine and chloramine.

As water flows through each filtration media, there’s a chance that it will create channels within the media. When such channels are created, water will go through them without coming in contact with the affected filtration media. In other words, some water will escape the filtration process and retain contaminants. The third filtration stage of the Springwell filter tries to eliminate this with a proprietary design called Flex Bed.

Flex Bed is meant to prevent the formation of water channels in filtration media. It also increases how long water stays in contact with the filtration media. Of course, with the longer contact time, we can expect a deeper level of filtration.

The fourth filtration stage uses a 5-micron sediment filter to remove both large and small particles from the water. So, if there are fine sediments like sand, clay, silt, or soil particles, the filter should take care of them.

The combination of these 4 stages offers a decontamination rate well above 90%. However, the company suggests the contaminant removal efficacy is as high as 99.6%

Springwell Whole House Water Filter vs. Similar Products

The large capacity of the Springwell filter system coupled with its high pressure makes it formidable when compared with similar products. The combination of these two qualities means that the filter can produce a large amount of filtered water in a very short period. So, even in times of high demand from the household, it would keep up.

When we compared the GPM of the three models of this filtration system with other top products, we found a similar level of performance. With the CF1, you can expect around 9 GPM or even slightly higher. The CF4 does 12 GPM, and the CF+ goes as high as 20 GPM.


  • Cost-effective
  • Excellent capacity
  • Does not lower water pressure in taps and showers
  • Healthier skin and hair
  • Offers more advantages over bottled water.
  • Does not need constant maintenance – change sediment pre-filters every 6-9 months
  • Eliminates chlorine
  • Comes with a lifetime warranty on tanks and valves


  • Installation may prove challenging for some people

How Do You Install The Springwell Water Filter?

Despite the challenges a few people might face with installation, the Springwell Whole House Water Filter System is easy to install. Because the system does not come preassembled, it is up to you to assemble and then install. The bypass valve included in the installation package makes the process much easier with straightforward visuals in the manual.

The additional components include a bypass valve, 1” MNPT fittings, the pre-filters mounting bracket, the Hose bib Assembly, the housing for the pre-filter, the spanner wrench for the pre-filter housing, an O-ring for the pre-filter housing (comes with lube), and a sediment filter.

Your Springwell filter can be installed outside as long it is not exposed to freezing temperatures. This filter system is remarkably effective and has great capacity.
