what's behind our
ratings

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.

Accessories

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.
