Disadvantages of Reverse Osmosis Filtration Systems

By Edited May 16, 2016 0 3

Reverse osmosis systems (or RO systems) are often installed in homes with the intent of purifying the drinking water. The idea behind it is that it is an easy, economical, and safe way to filter water. These systems are often recommended by very nice sales men. However, these sales men aren't always completely honest and don't always tell you the disadvantages to these systems.

How Most Systems Work.
Most of the RO systems are rented from a company. The company then comes and takes care of the reverse osmosis system for a monthly fee. Depending on your deal this could be a small fee or a much larger fee. All in all, it can become a very expensive filtration system.

Wasted Water.
In order to produce five gallons of fresh drinking water the reverse osmosis system flushes 50 to 70 gallons of water through its system. All of this water goes into the septic tank or sewer system as waste water. In a day and age where water is scarce and we should be concerned with the environment and how it is doing wasting water is definitely bad. However, there isn't a way to use an RO system and not waste water! Additionally many home owners who have septic tanks have additional problems. Some don't realize that this much water will be put through their system and they find themselves with overflowing septic tanks. Others know that this is the case and have to deal with the cost of pumping the tank. With all of these issues it should be noted that the cost of running the reverse osmosis system is a great one.

Reverse osmosis systems not only use a lot of water, they also use a lot of electricity. The use of electricity is bad for our environment and costly for those who chose to have reverse osmosis systems.

No matter how you look at it reverse osmosis systems are expensive. They not only have a starting fee or an equipment fee, they also have monthly fees, the cost of water, and the cost of electricity. It is all expensive. There are a lot of other filter options.

How It Works.
The reverse osmosis systems remove helpful minerals from the water. This makes the water that you drink less healthy then if you were to consume it from a different filter system. However, there is an additional problem. Those who claim all the wonders of the reverse osmosis systems, claim that it makes the water great. But that isn't the way it works. The reverse osmosis system doesn't remove harmful chemicals.

With all of these things, you really should consider other options when it comes to finding a filtration system for better water. After all reverse osmosis is expensive and dangerous for the community. It is also not near as good for us as we are lead to believe!

We had a reverse osmosis system installed in the kitchen about 6 to 8 years ago at the house we were living at then. We picked it up at Lowe's. We didn't experience any of these things. It was quite inexpensive to run and none of our utilities or water bill went up. In all fairness though, I can remember having a salesman come to the door and hoodwink my ex into buying an expensive water softener and so-called reverse osmosis system that was installed underneath the sink many many years ago. However, the on-going expense had to do with the water softener and not the reverse osmosis water filter at the tap.

An average reverse osmosis system uses about 15 gallons of water to produce 5 gallons of purified water, so your statistics in the article are off by a factor of 5 or 6. Unless you add a booster pump or a UV lamp, they use no electricity, contrary to your assertion that they use "a lot of electricity". And your claim that reverse osmosis doesn't remove harmful chemicals is simply untrue. Reverse osmosis systems will remove between 96 and 99.99% of chlorine and it's carcinogenic byproducts, organic chemicals, heavy metals, fluoride, lead, arsenic, cysts and other pathogens, and even pharmaceuticals and hormones that are in many public water supplies. Since you can pick one up at Costco or Home Depot for under $150 and install it yourself, it's one of the cheapest and most effective ways to ensure that your drinking water is clean and free from contaminants of all kinds. Just because some charlatans are ripping people off with these systems doesn't mean they don't work or are inefficient or ineffective.
