Frequently Asked Questions (FAQ)

What is the best faucet water filter?

It's no surprise that faucet water filters are the most popular type of water filter for the home. They are generally inexpensive, don’t require any installation, and therefore require far less effort than other water filter systems. They are also very elegant, compact, and produce excellent results. Plus, they are the easiest type to maintain and the most likely to be around once the others fall out of favor.

Most faucet water filters require no installation. They simply screw onto the end of your faucet giving you an instant water filter. Some, like the PUR Advanced Filtration System, have an attached filter and are mounted under the sink.

What is the healthiest water filter system?

Water filter systems can vary greatly depending on the specific model and price. Some provide more filtration and some provide less but a lower price. While there is a lot of variation, most models use an ultraviolet light, ceramic, or carbon to filter the water.

When choosing the best model for your family, you should consider the filter’s capacity, reliability, and how easy it is to service. Simply stated, the higher the amount of gallons a filter can filter, the less frequently you have to change it out. Likewise, more expensive and powerful filters are easier to service yourself. Many models make it possible to change the filter without having to turn off the main water supply.

Are faucet water filters worth it?

We love faucet water filters. They can potentially save you thousands of dollars in drinking water each year.

However, not all faucet filters are the same. They all do the same thing, but they vary tremendously in terms of quality of filtration.

Find out how to get the best faucet water filter that also provides plenty of healthy minerals and doesn't leach more contaminants back into the water.

What is the best material for filtering dirty water?

To filter dirty water, we recommend a four-stage system. This is how water is purified in the United States, but it often takes place in one big plant. Instead, the system provides optimal water safety at home.

First, the water should be filtered out in the environment. This usually occurs by filtering out the dirt through a sand filter.

Second, the remaining water should be filtered out using charcoal for impurities and controlling pH balance.

Third, remove any remaining chemicals using an iodine filter.

Finally, remove particulate using a final filter such as an activated carbon filter.

While there are other ways to purify water at home, this is the most effective way to do this. We've chosen these steps to help remove specific impurities from your water in a safe manner. Activated carbon is an excellent filter and is standard practice in US water filtration plants.
