Gravity Water Filter vs Reverse Osmosis
Gravity Water Filters and Reverse Osmosis both create healthy water by filtering out contaminants.
Both options are excellent at removing contaminants from water, but they are different in the way that they work and come with varying benefits.
This guide will explore the gravity water filter vs reverse osmosis. We will cover their key differences to ensure that you can find the right option for you.
What is a Gravity Water Filter?
Gravity water filters work by filtering water through the force of gravity. They are split into two chambers, with water coming from the upper chamber and becoming purified as it descends down to the lower chamber.
While a straightforward and simple process, a gravity water filter possesses the capability to remove a variety of contaminants, catching the larger contaminants at the top, before taking out the smaller ones at the lower end of the chamber.
It is a method of water filtration that has been used for a long period of time because it doesn’t require power or electricity, solely relying on the force of gravity.
What is Reverse Osmosis?
Reverse osmosis is a water filtration method where water is pushed through a semipermeable membrane in order to eradicate contaminated substances, such as pesticides and sulfates.
A regular reverse osmosis system will include numerous filtration stages. It is a beneficial household solution for clean water, where it can be fitted as a unit beneath the sink. Other features can be utilised to enhance the overall system, such as:
Primary Differences between a Gravity Water Filter and Reverse Osmosis
Purification:
- Gravity Water Filter: Filters out contaminants through its upper and lower chambers through the force of gravity.
- Reverse Osmosis: Purifies the water through a multi-stage membrane system.
Taste:
- Gravity Water Filter: While it certainly filters your drinking water, gravity water filters don’t remove all contaminants.
- Reverse Osmosis: Provides a much more thorough purification of water, providing a cleaner and nicer taste.
Complexity:
- Gravity Water Filter: Very simple to use. It doesn’t require power and has the added benefit of being portable, making it a good option for hiking and camping trips.
- Reverse Osmosis: More difficult to set up in terms of installing underneath a sink. However, once fitted, it provides a straightforward and clean supply of water. If needed, replacement filters aren’t too expensive.
Environmental:
- Gravity Water Filter: Reduces the need for plastic waste, limiting the necessity to buy bottled water from supermarkets.
- Reverse Osmosis: Uses energy to function and causes wastewater.
Price:
- Gravity Water Filter: Cheaper upfront, but can be more expensive as frequent use can lead to a regular need for filter replacement.
- Reverse Osmosis: Initially more expensive but requires less maintenance and helps you to save money in the long run.
Regarding your choice, it is worth considering what (if any) industry you need the water purifier for and the contaminants that you want to filter out.
What is the Better Option?
There is no definitive way to say which option is best. That comes down to your personal preferences, with many factors to consider.
A gravity water filter doesn’t require powering and will enable you to reduce your carbon footprint by cutting down on constantly purchasing bottled water. Simple to use, it allows you to make a cheaper upfront purchase and have a means to filter water on outdoor trips.
Reverse osmosis is a longer-term option that will cost more money upfront, but can be financially beneficial in the long run. It offers a more extensive purification of water that removes significant amounts of contaminants, providing clean tasting water that can also be used for cooking.
