We all know that we should drink at least eight glasses of water a day. Many people choose bottled water as they know this water is safe and free from any contaminants. The only problem is that bottled water is very expensive, especially if you live in a large household. Getting clean water from your mains supply is not always guaranteed, so a good option is to install a water filtration system in your home. An osmosis filter system comes up as one of the best options, but because there are so many makes and models in the market, how do you choose the best one?


The first factor you should consider is the cost. Reverse osmosis systems, for example, will fall in a large price range but in most cases, the more expensive the system, the better it is. The more expensive systems usually have more filtration stages, the ability to filter large amounts of water at once, and many other useful features. Some of them are also able to add useful nutrients and minerals to the water after it has been filtered. 


The most common types of reverse osmosis systems are those that live on top of your counter and those that are installed under the sink. Regardless of the system you favor, space is an important consideration to make.

If you have limited space on your counter, a large filtration system will clutter the space. If you decide to add one under the counter, it has to fit under there. 

Ensure you measure the space you have and read the size specifications of the reverse osmosis system you want to buy on the retailer’s website.

Amount of Filtered Water

A reverse osmosis system should produce enough water for your needs depending on the number of people in your household. Most of these systems have specifications provided on how much water you will get out of them in a given amount of time. 

If you have a small household, about 50 gallons a day is a good place to start.

Number of Stages

The number of stages is simply the number of filters the filtration system has. These include filters for things like dirt and sand (sediments), a carbon filter for chemicals such as chlorine, and a reverse-osmosis membrane to remove any impurities that remain.

For a good balance between cost and size, you should go for a reverse osmosis system that has five to six stages.

Ease of Installation and Use

How difficult it is to install the filtration system will determine how much you pay the contractor to do it for you. A system that is easy and straightforward to install is the best option.

Although a filtration system is easy to use, you have to maintain them. Things like replacing the filter and cleaning the system are all important considerations to keep in mind. If you know you will find it hard to do these maintenance tasks regularly, find a system that can go for longer before it needs maintenance.

Choosing the right filtration system for your home depends on a lot of things. The most important of these include the amount of water produced and how well the system filters the water.
