Effectiveness

Of course, you will want to make sure that the filter system you choose removes all of the impurities from the water. Take a close look at the types of impurities that are removed as well as the percentages. For example, the best inline water filters claim to remove up to 99.9% of all known contaminants.

The filter should also remove any unpleasant odors and tastes from the water. This means that it will be left with an improved taste and without lingering odors. After it has been filtered, this water will be safe and even pleasant to drink.

Location, Location, Location

Spare a thought for the place where you are planning to install your new inline water filter. You will need to make sure that you have enough available space to complete the installation process. If your model needs to be installed behind the refrigerator, make sure that your kitchen is large enough to accommodate this.

Most filters of this type are designed to be installed underneath the kitchen sink. This is a space saving solution that prevents your counters from becoming cluttered. However, it should be noted that top of the range models tend to take up quite a bit of space.

The Filter Lifespan

Different filters are designed to last for a certain amount of time, which is quoted by the gallons they filter. Basic models generally start at 750 gallons, while this can go all the way up to 20,000 gallons. Depending on the number of gallons, you can expect the filter to last from three months to three years.

As a result, the exact lifespan of your filter will depend on how much water you actually use. If you live alone, a 750-gallon inline water filter is likely to last much longer than three months. However, large families are likely to use the allotted 750 gallons much more quickly.

The Filter Use

The best inline water filter for your needs will depend on what you want to use it for. Some models are designed specifically to be used with an icebox or an RV. However, other models are intended to filter the water of the entire house.

Replacing the Filter

Last but not least, take a look at how easy the filter is likely to be to replace. Some inline water filters have to be completely dismantled in order to replace the filter. However, the best inline filter system is likely to provide you with quick and easy access to make the process easy.

The Flow Rate

Traditional water filters are known for reducing the water flow rate while they remove contaminants. This can be a bit of an issue if several people are using the water supply at the same time. However, this is not such an issue when it comes to the best inline water filter.

If you are simply planning to install the filter on an icebox or refrigerator, the flow rate will not be an issue. Similarly, if you live alone or with one other person, it will not be a concern. However, large households should pay close attention to the water flow rate to make sure that it is sufficient.

The Installation Process

Installing a new inline water filter is generally a quick and easy process. However, this is not always the case. Some models come with a large number of parts that can be a little overwhelming if you are a novice.

To make the installation process as easy as possible, make sure that you have everything you need before you start. Some models come complete with a full installation kit. This saves you the time and trouble of tracking down all of the necessary parts.

Top of the range models should also come with a set of clear installation instructions. This will allow you to follow the step by step guide to get the job done. If you have everything you need at the start, the whole process should only take a few minutes.

Other Filtering Options
