Is an under sink reverse osmosis water filter right for you?

Deciding to move to a reverse osmosis water filter to remove microplastics from your drinking water is already a great step, but you might be wondering what kind of reverse osmosis filter you should get. 

RO filters are commonly broken down into categories - under the sink, and countertop. 

Countertop filters are generally easier to install, being plug and play solutions that require no technical changes to your plumbing and can help you start drinking microplastic-free water right away. Some consumers may be in a situation where they are moving often, or are unable to make changes to their plumbing (in an apartment, for example), so a countertop would be a perfect solution.

However, countertop RO filters will generally be more expensive, and need their filter units replaced more often. Additionally, they filter water more slowly and require manually dumping residual water and refilling of containers, which could be cumbersome if you and your family drink a lot of water daily.

Also, countertop water filters are quite large, nearly the size of a PC tower and could take up precious countertop space in your kitchen.

Both variants require remineralization at some point before drinking to ensure you are re-adding important trace elements that are found in water naturally, but some products can automatically add these elements back into your drinking water, which we will mention in picks.

If an under sink variant sounds like the option for you, read on to see our recommended picks.
