Improve Your Home’s Water with Reverse Osmosis System

Unless you are one of the people who cares about the quality of water that you’re drinking, you probably don’t know what reverse osmosis is.

reverse osmosis water system

Reverse osmosis basically removes contaminants from the water, making the water purer. When the water is filtered, the freshwater is called permeate and the leftover waste/dirty water is basically called the brine. So basically, all the bad stuff in the water that you hear about is removed by reverse osmosis.

Now that you have an idea of what it is, read on to see why you should have a reverse osmosis system and why we picked some of the best ones on the market.

How to choose

These are the following factors that you should consider before buying a reverse osmosis system for your home:

Water waste

Believe it or not, not all water that’s pumped through the reverse osmosis filter is all pure water. You will be lucky, maybe 50% or less is safe to drink. The rest is actually waste. When looking for a RO system, make sure you get a unit that gives you at least 50% or more that is safe to drink vs waste.


Filtering gallons of reverse osmosis water takes a lot of time, so you’ll want to consider getting a larger tank/container if you and your family are planning to drink filtered water all day long.


There are some reverse osmosis filters that can filter water exactly when you need it, but a lot of time likes to take their sweet time. If drinking filtered water is going to be a thing for you and your family, you should consider a system that can filter 50 gallons or more a day.

Different Types of Reverse Osmosis Systems

Benefits of Reverse Osmosis

Clean Water

Reverse Osmosis water is much safer to drink than regular water. It reduces your risk of dangerous components and you won’t even need to drink from bottled water anymore once you’ve started drinking reverse osmosis water. Also, it filters out dangerous components such as:

  • Lead
  • Salts
  • Particles/Parasites
  • & more

Tastes better

It’s one of the reasons why we drink liquids in general. Because it tastes good. If the water smells awful, it’s likely either magnesium or sulfur, which is plain nasty. But if you have a reverse osmosis system, it filters out that nastiness and you’ll have filtered, crisp, clean water to drink or to use for dishes.

Saves Money

We live in such an expensive world as it is. The cost of groceries is going up; bills are piling up and there doesn’t seem to be a break. If you’re continuously buying bottled water, that can be very expensive. However, if you get a reverse osmosis system, you’ll save so much money on water alone because you’ll be drinking clean water for practically free.
