How To Choose the Right iSpring Filtration System

Now that you’ve gone over the 3 best iSpring water filters out there – it is time to learn how to pick the ideal one. Here are some factors to consider:

Types of Filter (Stages)

There are various types of filters and/or stages to consider. For example, a 3-stage filter will make the water go through a sediment filter that gets rid of most large particles like dirt and debris. Then, the water goes through CTO carbon filters that get rid of the smallest particles. Here, the water is drinkable.

For a 6-stage filter, however, the process adds up several stages. Apart from sediment and CTO carbon filter, you may also add the alkaline filter, which re-mineralizes the water to make it nutrient-rich. Then you find the RO (reverse osmosis) system that passes the water through red mineral stones.

And finally, you can find the extra stage; usually, it is a UV filtration system. This filter can get rid of germs that only UV light can kill. With this filter along with the others, you can enjoy the healthiest water out there.


When it comes to installation the filtration system, it shouldn’t take more than 3 hours. Any filter that takes more time than that is probably too tricky and may take more maintenance effort eventually.

For the smallest filters (3-stage), you shouldn’t waste more than an hour installing the piece. And you should be able to do it alone – even if you have little to no experience.

Lastly, make sure the filtration system has clear instructions and 24/7 available support. If you can’t install the filter, support may always help you out via voice call.


The last thing to consider when choosing an filtration system is how many extras it offers. There are several things to consider here.

One would be the faucet. A filtration system that comes with its own faucet will make the entire installation a lot easier – especially when having to look for a compatible piece. Make sure it is durable and good-looking, though. You don’t have an ugly or fragile faucet even if it is practical.

Another excellent extra to consider is a booster pump. These pumps will increase the overall efficiency of the filtration system, aiding to save water, and prevent waste. And sure enough, it will help to filter even faster than usual.

Last but not least, consider housings, fittings, and filter replacements as useful extras as well. They will make the installation easier, but also the entire maintenance process.

The more extra features you find on the filtration system, the better. So don’t dismiss them to get an even better value for your money.


There’s nothing healthier or safer than drinking clean water. That’s where an iSpring water filter enters into action. And that’s also why you should get one.

After taking an in-depth look into the different models available and the overall quality they offer – it is time you pick the one that better matches your needs. It will make your water-drinking experience at home much better.

So, what are you waiting for? Don’t drink filthy and contaminated water anymore. Get one of these filters now – you won’t regret it!
