Top 3 Whole House Water
Filter Comparison

what's behind our

Filtering Technology

The type of technology used by a certain whole house filter says much about its performance. The finest units use several cartridges and incorporate innovative technologies that work together to make the water safer for drinking. The more cartridges included and the more advanced the technology used, the wider the range of pollutants eliminated from the water.

Contaminants Removal

Without a doubt, the amounts of contaminants a water filter can remove is essential when deciding on its efficiency and reliability. A good filter can handle bacteria and heavy metals with the same ease it handles large sediments and it can also remove the unpleasant chlorine odor that makes water hard to drink.

Flow Rate

The flow rate represents how much water runs at your tap in a certain amount of time and is measured in gallons per minute. Although some people are worried about the fact the water runs through a series of filters, you must know that the flow rate should not be altered by the water filter. A reliable unit maintains a high water flow regardless the filtering process.

Filter Capacity

It’s also useful to analyze how many gallons of water the filter can handle before requiring a cartridge replacement. Some filters have a capacity of 300,000 while others can reach an outstanding 1,000,000 gallons, meaning that the cartridge will not have to be replaced in as much as 10 years.


Some whole house filtering systems include a UV light that can kill dangerous viruses in the water while others are paired with a water softener that can solve the hard water issue. These additional features extend the utility and convenience of the whole house filter and make it an even wiser improvement.

Ease of Installation

Given the fact that a whole house system is installed on the main water pipe, it’s important to find the model that doesn’t require too much plumbing. A unit that is easy to install will be ready to use faster and will eliminate the need to pay for a plumber.

The Filtering Systems Evaluation

1. Pelican PC1000 System

A high-capacity system that you can easily install on your own if you have the right skill set, the PC1000 is desirable for a wide array of reasons. It is virtually maintenance-free, which adds to its value as you won’t need to make expensive replacements or waste personal time on tedious tasks too often, but rather only once every 6 to 9 months. When it comes to the removal of chlorine, a common and harmful water pollutant, this is the system that best handles it. Of course, as it takes care of purifying the water before it reaches the taps and all water dispensing sources, it helps improve your health as you will hydrate properly, it will boost the taste of your meals as the water you use when cooking will actually be clean, and it will provide you with contaminant-free water to bathe/shower with, thus helping improve skin and hair health.

Filtration Technology

To provide these exceptional results, it passes the water which runs through your pipes through 4 different filtration stages before releasing it. During each of the 4 stages, certain issues of contaminants are handled for optimum results to be guaranteed.

  • Stage 1: During the first filtration stage, a 5-micron pre-filter system is employed. This system helps reduce sediment, debris, silt, and sand found in the supplied water down to 5 microns in size. To protect plumbing and the water-using appliances from excess sediment and to ensure a proper efficiency of the system as a whole, you should replace the filter once every 9 months at tops.
  • Stage 2: In the second stage, a catalytic granular activated carbon media is used. The role it plays is quite a crucial one as it tends to the removal of chlorine, pharmaceuticals, chloramines, pesticides, herbicides, solvents, and hundreds of other health-threatening impurities.
  • Stage 3: Just like in the second stage, during the third filtration stage another catalytic granular activated carbon media is used to further remove any contaminants that have escaped the first GAC media.
  • Stage 4: In the last stage, a copper and zinc oxidation media also known as KDF-55 is utilized. It has the purpose to prevent and reduce the growth of algae and bacteria, thus ensuring a sanitary environment and a complete lack of health-damaging microorganisms in the water you use and consume.
Filtration Capacity

As aforementioned, the water pollutant against which the system fights the most is chlorine as it is ever-present in all American household, unfortunately. This contaminant is all the more dreadful as it alters the taste and smell of the water, thus making you less inclined to consume it and maintain a proper hydration. Of course, this isn’t where the list ends as there are other health-threatening contaminants the system helps remove or reduce. Some of the most important contaminants it fights against include chloramines, particulate matter, MTBEs, atrazine, xylene, VOCs, PAHs, THMs, heavy metals, sediment, herbicides, pesticides, insecticides, and hundreds of other harmful contaminants and chemicals.
