What is reverse osmosis?

This technology was originally invented to improve seawater for regular consumption. Additionally, these machines are designed to remove heavy metals and other chemical contaminants from tap water.

Basically, reverse osmosis refers to a process that filters your tap water and removes various types of dissolved minerals.

What can you remove using a reverse osmosis filter?

Reverse osmosis units remove various types of contaminants from your tap water. Some common contaminants on this list include sodium, potassium, calcium, and magnesium. In fact, you can remove hundreds of these elements from plain water. And the good thing is that the efficiency of these devices is 99%.

But these devices have their own set of limitations. For example, you cannot use them to remove chlorine or to soften water. Because of this, these units come with activated carbon filters that can help remove more than 70 types of contaminants, such as pharmaceuticals, chlorine byproducts, herbicides, and pesticides.

RO filters can help reduce the TDS level

With a TDS meter you can measure the dissolved elements in your tap water. However, you cannot take a decision based on the TDS readings. If the TDS rating of your regular water is more than 150 PPM, it means that your tap water contains a lot of minerals. And that might be good news.
