Pros of Under Sink Water Filters

Moreover, under sink water filters directly get connected to your house’s water lines, so they don’t take up any space in your fridge as well. 

2. Water Flow

2. Pricing

Countertop Water Filtration Systems 

An alternative to under sink water filters, a countertop water filter is a good option to go with when you’re looking to buy a water filtration system. Known as point-of-use systems, countertop water filters can be installed wherever you need them.

These filters don’t require a lot of effort to assemble and install, and they fit on your kitchen’s countertop.

These filters have their own set of advantages and disadvantages. Let’s go through some pros and cons of countertop water filters: 

Pros of Countertop Water Filters

1. Installation Process 

The installation process of a countertop water filter is very convenient when you compare it to the installation process of an under sink water filter.

Most countertop water filters don’t even require any plumbing or installation. This means that all you’ll have to do is unbox the filter and plug it in to start getting filtered water.

Cons of Countertop Water Filters

As a countertop water filter fits on your kitchen counter, it takes up space. If you’re short on countertop space or don’t like your countertop to look messy, we suggest you consider buying an under-sink water filter. 

2. Its Size

Countertop water filters are compact, meaning they don’t have a lot of water holding capacity. As a result, countertop water filters may not be able to store a lot of water at a time, and it won’t be suitable for you if you have many members in the house and heavy water usage. 

Under Sink vs Countertop Water Filter: Final Verdict
