My Buying Guide on ‘Best Under Sink Reverse Osmosis’

Introduction

As a homeowner, I know the importance of having clean and safe drinking water. After researching various options, I found that under sink reverse osmosis (RO) systems are one of the most effective and convenient ways to purify tap water. In this guide, I will share my personal experience and provide you with all the necessary information to help you choose the best under sink reverse osmosis system for your home.

Benefits of Under Sink Reverse Osmosis

Under sink reverse osmosis systems have many advantages over other types of water filtration systems. Some of the main benefits include:

– Removes contaminants: RO systems use a semi-permeable membrane to filter out impurities such as chlorine, lead, bacteria, and viruses from your tap water.

– Improves taste and odor: By removing impurities, under sink RO systems can significantly improve the taste and odor of your drinking water.

– Space-saving design: Unlike bulky countertop filtration systems, under sink RO systems are installed under your kitchen sink, saving counter space.

– Cost-effective: Although the initial cost may be higher compared to other filtration methods, under sink RO systems have low maintenance costs in the long run.

Factors to Consider

Before purchasing an under sink reverse osmosis system, here are some important factors to consider:

Water Quality

It is essential to know the quality of your tap water before choosing an under sink reverse osmosis system. You can get a water quality report from your local utility company or use a home testing kit. This will help you determine which contaminants need to be removed from your water.

Filtration Stages

The number of filtration stages in an RO system determines its effectiveness in removing contaminants. Generally, more stages mean better purification results. Look for a system with at least 5 stages for optimal performance.

Water Waste Ratio

RO systems produce clean drinking water by filtering out impurities and flushing them down the drain. This means that some amount of water is wasted during the purification process. Look for a system with a high efficiency rating to minimize water waste.

Installation and Maintenance

Under sink RO systems require installation by a professional plumber or DIY installation if you have basic plumbing skills. Consider the complexity and cost of installation before making a purchase. Additionally, look for a system with easy maintenance procedures such as filter replacement that can be done without any special tools.
