In this buying guide, I will share my personal experience and provide you with the necessary information to help you make an informed decision.

Why choose a reverse osmosis under sink system?

There are several reasons why I prefer a reverse osmosis under sink system over other options such as countertop or pitcher filters. Firstly, it provides a more thorough filtration process by removing up to 99% of contaminants including bacteria, viruses, heavy metals and chemicals. This ensures that the water I drink is safe and healthy for me and my family. Secondly, it saves counter space as it is installed under the sink, giving a clutter-free appearance to my kitchen. Lastly, it produces a large amount of filtered water compared to other options, making it convenient for larger households.

Factors to consider when buying a reverse osmosis under sink system

1. Filtration Process

The most important factor to consider is the filtration process of the system. Look for systems that use multiple stages of filtration including sediment filter, activated carbon filter, reverse osmosis membrane and post-filter. This ensures that all types of contaminants are removed from your drinking water.

2. Water Pressure

Another important factor is the water pressure required for the system to function effectively. Make sure to check your home’s water pressure before purchasing as some systems may require additional pumps or adjustments.

3. Storage Capacity

The storage capacity refers to how much filtered water the system can hold at once. If you have a large household or frequently use large amounts of water, look for systems with larger storage tanks.
