Airthereal Reverse Osmosis Countertop Water Filter with Premium Glass Pitcher - 5 Stage Purification for Safe Drinking, No Installation RO Filtration, Purified Water Dispenser, Pristine Lite3: desertcart.com: Tools & Home Improvement

Review: An Excellent Investment - This is one of the best purchases that I am truly happy that I have made. I have a Berkey filter but the Airthereal is not just carbon filtered water, it is a reverse osmosis filtration system. It is so easy to set up and use and the filtration occurs so quickly. The Berkey filtration takes some time to complete. The water is filtered into a glass pitcher and has a nice, crisp, clean taste. The pitcher holds about 68 oz which is not a problem because the filtering process occurs so fast.
Review: A M A Z I N G ! yes - This machine is the REAL DEAL! The water in our city is HORRIBLE and runs anywhere from 520~ 740 ppm's. I bought this machine in early April last spring, and we have used it every day multiple times a day for EVERYTHING water/food. We have not even replaced the filters yet and the machine is still filtering the water anywhere from 8~14 ppm's. A M A Z I N G !! The machine is perfect size for our counter top next to the sink. Water sits at room temp which is preferred in our home. There are four different heat settings as well as four different size distribution. BUY THIS MACHINE ! What a value for this cost! Life Saver !! (sorry for blurry pic)

## Questions & Answers

**Q: What are the differences between RO systems and standard water filter pitchers?**
A: RO systems use a semi-permeable membrane to remove dissolved solids, heavy metals, particles & other pollutants, producing purified water. Standard filter pitchers use activated carbon to remove chlorine, odors, and larger particles.

**Q: How to handle the wastewater generated by reverse osmosis?**
A: Wastewater will be generated by reverse osmosis, Wastewater needs to be dumped regularly. The wastewater can be used for plant irrigation or cleaning purposes. This helps to reduce waste water and decrease the demand for water resources.

**Q: Is RO water as good as bottled water?**
A: RO water, with its removal of particles, chemicals, and impurities, generally has higher quality compared to most bottled water. Also it helps avoid the need to purchase and dispose of plastic bottled water.

### ⭐ Didn't work very long
*by A***R on February 5, 2024*

The water tasted great and I loved the convenient set up. However it only lasted 2 weeks before it would no longer filter water through. I don't know if it already needed new filters but I just returned it instead of trying new ones.
