You can set up the unit yourself, but if you need assistance, there are plenty of videos online that show how to do so.

This is a highly efficient model, with all the basics that you’ll need for a decent water filter. It has a great build quality and does not compromise on performance.

The main difference between this and the previous model is that it uses carbon technology instead of chlorine removal.

Carbon filters are much cheaper to produce, but they don't remove the same amount of contaminants.

This will result in clean and healthy water that will be noticeably different from the water you were drinking before.

The CuZn UC-200 works by using a triple filtration process.

There are a few must-have features for any under sink water filter. Firstly, you’ll need to think about how big it is and whether you can fit it under your sink.

You’ll also have to think about how much water it saves you and whether it will last you for 6 months or 6 years.

Here are a few features you should be looking for:

If you’re going to be living in an apartment, then you don't really need a large filter. However, if you’re moving into a house, you’ll definitely want a larger filter.

A bigger filter means that there will be more room for water to flow through. That way, you’ll save more water.

You’ll want to know what type of water it filters.

There are two main types of water: soft and hard. Hard water contains higher amounts of minerals such as calcium and magnesium.

These minerals can cause problems when they get into your pipes. Soft water doesn't contain these minerals and therefore isn't as problematic.

You’ll find that most units only filter tap water. They don't filter bottled water because they don't have enough filtering power.

Most people will tell you that installing an under sink water filter is pretty simple. In fact, it takes just a few minutes.

What you’ll need to do is unscrew the old filter, place the new filter in its place, and tighten everything back down.

As long as you follow the instructions, you shouldn't run into any problems.

However, if you’re not sure how to install it, we recommend contacting a professional plumber.

The amount that you’ll save depends on where you live. Some areas charge by the gallon while others charge per month.

Most states charge based on the size of your home. For example, if you live in a 1,000 square foot house, you’ll pay $20-$25 per month.

Most manufacturers recommend changing your filter every six months. However, some say that you can go longer than that.

Yes, although this will contribute to your overall water usage.

No, although you might consider replacing it if it has been leaking for a while.

Yes. All filters are made out of plastic and stainless steel. Therefore, they are completely safe and will be easy to clean when the time comes.

No, most of these units are designed to be kept under your sink.

When your unit does eventually give out, you’ll have to get it replaced completely. You should also change the filter every 6 months to promote longer life.

This varies depending on the brand and model. You should expect to spend between $50 and $100 for a good quality one.

We hope our list of some of the best under sink water filters has helped you to narrow down which one you’ll need for your home.

Remember that you’ll also need to consider the number of people in your home, how many rooms you’ll want to filter and how much water you’ll be needing to filter on a regular basis.
