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.

Frequently Asked Questions

1. How effective are these systems in terms of contaminant removal?

All systems do a more than an astounding job when it comes to contaminant removal, especially for chlorine contamination. However, there are major differences between the capabilities they boast as these products use different filtration media and have unique features, thus some systems being more prolific than others. High-end systems generally remove the following water contaminants – chlorine, chloramine, VOC’s, pesticides, herbicides, lead, and mercury.

2. What maintenance work is required to preserve performance quality?

As the system utilizes filtration media to remove the unwanted contaminants present in potable water, the main maintenance task which must be regularly performed is to replace the media. Pre-filters and filter cartridges have different necessities in terms of replacement, so you should check the user manual to see what is the lifespan of each and all filters used by the system you own. Pre-filters generally require being replaced 1-2 times per year, while filter cartridges, depending on their capacity, requires less maintenance work. For example, a filter cartridge with a 1-million gallon capacity could require replacement once every 5 or 10 years.

3. What is the role fulfilled by UV filtration technology?

The UV technology takes water purification to a whole new level as it endorses the destruction of microorganisms, more precisely up to 99.9% of bacteria, viruses, and germs. Chemical-free and cost-effective, it is an appealing feature of water cleaning systems as it greatly heightens contaminant removal efficiency, leaving behind clean and safe water for consumption and use.

4. Does the number of filtration stages used by the system affect its performance?

The number of filtration stages used indicates how many separate filtration processes the water will be passed through, so it can be considered an influential spec in terms of performance quality. However, the types of media utilized by the product have a greater effect than the number of media it features as certain filter cartridges are more effective in contaminant removal than others or they cover a wider range of impurities. Thus, it is best to look at both aspects when deciding what is the right system to go for.

5. Does the water cleaning system impact flow rate and water pressure in any manner?

Yes, the system does affect flow rate and water pressure, so special caution is due when purchasing and installing it. The whole house system produces a sort of choke point when its filtration media gets clogged or if it is picked wrongfully to start with. Before you settle for a specific product, calculate the water demand of your home to know what is the system type you need. If you cannot do the calculation on your own, call in a professional plumber to make sure you get the right stats.
