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

A low-maintenance, easy to install system we regard as being the best product in its niche is the PC1000 produced by Pelican Water Systems. In terms of performance, it is hard if not impossible for any other filtration system intended for whole house use to surpass it due to its superior capacity and contaminant removal capability. Unlike most systems of its kind, it actually tends to the elimination of chloramine, a powerful and dangerous water pollutant you do not want to enter into contact with, let alone ingest it. Other important contaminants it removes include chlorine, volatile organic compounds, mercury, herbicides, and pesticides.

One of the media which gives it this high performance is the 5-micron pre-filter system that reduces water content like debris and sediments down to 5 microns, making it easier for them to be eliminated. We must mention the fact that this pre-filter system actually need maintenance work done on it only once every 6-9 months. Thus, you won’t spend too much money on filter replacement. Additionally, considering the fact that the lifespan of the unit itself is 5 years or until it filters approximately 1 million gallons of water, not a lot of money will be spent on keeping it in a top notch shape.

The 15 gallons per minute flow rate it delivers ensures you won’t have any issues with water flow after installing the system, regardless of how large your home and household are. Another highlight worth mentioning is the fact that it utilizes a granular activated carbon media in addition to the pre-filter and the KDF-55 filter, providing the purest quality water as even unwanted odors are eliminated. Furthermore, it is produced by one of the best manufacturers on this market with the highest quality parts and materials, so performance, durability, and reliability will never be an issue with it.
