Buying Guide
When looking for the best 7 stage reverse osmosis water filtration system, there are several factors to consider. Here are some key features to look for:
1. Filtration Stages
The number of filtration stages is an important factor to consider. A 7 stage RO system typically includes pre-filters, a reverse osmosis membrane, and post-filters. Pre-filters remove larger particles, while post-filters polish the water. Look for a system with a variety of filters to address specific contaminants.
2. Membrane Quality
The quality of the reverse osmosis membrane is crucial to the system’s effectiveness. Look for a membrane with a high rejection rate and low TDS (total dissolved solids) level. A good membrane should remove up to 99% of contaminants, including fluoride and chlorine.
3. Flow Rate
The flow rate of the system is another important factor to consider. A high flow rate means that more water can be filtered in less time. Look for a system with a flow rate of at least 50 gallons per day.
4. Storage Tank
A storage tank is necessary to store the filtered water. Look for a tank made of food-grade material and with a capacity of at least 3 gallons.
5. Installation
Installation is an important consideration when purchasing a RO system. Look for a system that is easy to install and comes with clear instructions. Some systems may require professional installation, so be sure to check the manufacturer’s recommendations.
By considering these key features, you can choose the best 7 stage reverse osmosis water filtration system for your needs.
