1️⃣ Distillers

  • Distillers do an excellent job at eliminating contaminants from water. The water quality matches reverse osmosis. In fact, experts consider distilled water to be one of the purest forms of water for a balanced diet. During distillation, water is first boiled and turned into vapors. These vapors are then condensed and turned into a liquid form free from all impurities.
  • The problem with distillers is that they can be very time-consuming, have electrical energy consumption, and the output can be meagre and not worth the effort required.

2️⃣ Alkaline Filters

9 Best Alternatives To Reverse Osmosis Systems (2023) - Aqua Professor (1)
  • These filters are the exact opposite of reverse osmosis filters. While reverse osmosis filters remove all types of impurities from water, alkaline filters are used to remineralize water and add back the vitamins and minerals needed in the water.
  • Alkaline filters do nothing to filter the water for contaminants like lead.

3️⃣ Carbon Filters

  • Carbon filters are a great option for having an affordable filter that can easily remove bacterial contamination and produce healthy fresh water. These filters are not expensive; they inhibit bacterial growth, remove chlorine very well, and retain the essential minerals in the water.
  • The downside is that they do not perform well when removing sediments, viruses, excess minerals, etc. Carbon filters can be activated carbon blocks or granular activated carbon.

4️⃣ Sediment filters

Reverse osmosis filters do not remove the sediments themselves. Even they use a sediment prefilter to remove sediment impurities from water. Sediment filters help remove contaminants with a size of 5 microns or larger.

5️⃣ Water pitchers

  • A handy alternative to reverse osmosis filters are water pitchers. They are small, easy-to-use filters that can provide you with instant filtered clean water.
  • The main downside of water pitchers is the capacity. Since they are small, the filtration capacity is really low and may not be suitable for all households.
  • Produces more waste water than RO systems. You have to replace filters every two months, twice as much as a traditional reverse osmosis filter.

6️⃣ Ion Exchange

9 Best Alternatives To Reverse Osmosis Systems (2023) - Aqua Professor (2)
  • The ion exchange method is another alternative to reverse osmosis. The water is passed through a resin bed where the unwanted mineral ions are exchanged and eliminated. The water is made free from all kinds of mineral and inorganic impurities.
  • The ion exchange method’s downside is that it cannot remove organic impurities like bacteria, organic chemicals, etc. Moreover, the resin bed itself becomes vulnerable to bacterial growth over time.

7️⃣ UV + UF

  • The ultraviolet filtration technique is very efficient at killing the microorganisms in the water. It eliminates all bacterial contamination from water and provides clean, healthy water. They are an energy-efficient low-cost type of filtration technique.
  • The downside is that UV can only filter out microorganisms and bacterial impurities, and they do not work well with inorganic and other sediment contamination in water.

8️⃣ Gravity Filters

  • These are portable water filters. These can be used to filter water that comes from natural sources like water or lakes. They can provide you with instant fresh water. They can come in very handy when going on a nature adventure.
  • The limitations include a slower filtration rate than pressured water filters, less capacity, and lesser efficiency.

9️⃣ Countertop Filters

These small, easy-to-install filters are a good option for smaller homes and people on a budget. Although, you must note that countertop filters, being smaller in size, have a lesser output volume and may not be able to keep up with your household needs.

As a final note, know this:"When filtering water you have to start with your reason for filtration before you determine the environmental impact. For example if someone says, "I have lead in my drinking water", then Alkaline, Carbon, and Sediment filtration won't do any good. *you can get Carbon filters with lead reduction*, but again, you have to determine need before environmental.This is also true if you live in an area with almost perfect water. (I used to live where the water from the aquifer was almost perfectly clean and soft with no treatment). In this case we used sediment only because everything else was good." -u/PercMaint in r/WaterTreatment

Why Shouldn’t You Use Reverse Osmosis? (Medical Science)

9 Best Alternatives To Reverse Osmosis Systems (2023) - Aqua Professor (3)

When it comes to the use of reverse osmosis as a filtration technique for water, there are many myths surrounding the topic. With the growth of the internet and social media, it has become easy to get anything and everything up on the web. It becomes difficult in such scenarios to tell myth from fact.

But don’t you worry, I’ve got you covered. Yes, reverse osmosis has some disadvantages, but not everything negative that you find online about RO systems is true.

Let’s discuss some common myths about reverse osmosis:

#1 Myth: Minerals in Drinking Water Are Necessary

Fact: While minerals (up to a certain amount) are necessary for the body, the source of the minerals is hardly ever an issue. Also, most of the body’s mineral requirements are taken care of by the food intake one gets.

Even in the best-case scenarios, only 6.5 percent of mineral requirements is provided by water consumption, and the rest is up to the food.

So, even though reverse osmosis water may lack certain minerals, it is not necessarily a major downside for the treatment method. Also, there are several ways in which one can have their reverse osmosis water remineralized.

#2 Myth: Reverse Osmosis Water Attacks the Body

9 Best Alternatives To Reverse Osmosis Systems (2023) - Aqua Professor (4)

Fact: Even though reverse osmosis water may have low TDS levels, the notion that it may cause the degeneration of mucous membranes of the body or cause deficiency of minerals in the bloodstream is wrong.

No proven studies can say that the consumption of water with low levels of total dissolved solids causes any major health problems.

Many studies and surveys, including those done by WHO, say there is no health-based guideline value for TDS levels in water and that they are not established because it is not of health concern at levels found in drinking water.

#3 Myth: Alternative Technologies Are Just as Effective

Fact: Yes, there are quite a few alternative options available for reverse osmosis, but you have to keep in mind that they may not be as effective as reverse osmosis technology. The others might eliminate impurities up to a certain level.

Still, only Reverse Osmosis successfully eliminates all and every type of contamination, providing you with nothing but the purest form of drinking water.

Now that we have addressed some myths about reverse osmosis water, it’s time to flip over to the other side of the coin, i.e. the disadvantages.

There are a few disadvantages of reverse osmosis water as well, which are discussed in detail below:

  • There is no doubt about the efficiency of reverse osmosis filters. These filters are so good at what they do that they literally eliminate everything from the water. The result is the removal of even the healthy minerals from water. The reverse osmosis treated water lacks certain vitamins and minerals and becomes demineralized.
  • The reverse osmosis filters are so good at what they do that they come at a price that might not be low. Reverse Osmosis filters can be expensive, and maintenance isn’t a piece of cake either. The filtration systems are expensive, and the filters might cost you a lot with the frequent replacement needed to keep functioning effectively.
  • Since reverse osmosis treated water does not have any sort of minerals or vitamins, the pH of such water may not be as alkaline as mineralized water. This lack of alkaline water may cause it to develop a flat taste that everyone may not appreciate.

Due to such limitations of the reverse osmosis filter, there are a few alternatives to this treatment method which we have already discussed earlier.

When Should You Not Consider RO Alternatives? (Don’t Ignore This)

9 Best Alternatives To Reverse Osmosis Systems (2023) - Aqua Professor (5)

We have now covered the disadvantages and alternatives of reverse osmosis water. However, it is not always disadvantageous to use reverse osmosis. There are situations wherein the use of reverse osmosis water becomes necessary.

Also Read: Top 5 Waterdrop Filters

Before we dive into what all situations ask for the mandatory use of reverse osmosis, let’s understand how exactly the RO systems work.


Reverse osmosis water filtration systems, or RO, are a purification technique used to eliminate contamination from water. Reverse osmosis uses a semipermeable membrane, and impurities and contaminants are removed from drinking water via diffusion through the semi-permeable membrane.

During reverse osmosis, two streams are formed, the solute stream and the solvent stream. In this case, the solvent stream is what is of use to us, as it is the purified drinking water suitable for consumption. The solute stream eliminates all sorts of chemical and organic impurities.

The reverse osmosis process is an excellent water purification method when the main water issue you are facing is the presence of bacterial and organic contaminants. The reverse osmosis membrane successfully removes all herbicidal or pesticide impurities from water.

While this may be a plus point for reverse osmosis, the downside is that reverse osmosis water may lack certain minerals like calcium, magnesium, iron, etc., that are necessary for human needs. Other than that, they are expensive and have tiresome maintenance considering replacement filters, etc.

Now, let’s talk about when exactly you should not consider reverse osmosis alternatives. There are some situations where going for a reverse osmosis alternative won’t suffice. Sometimes, the job can only be done by RO filters.

If you’re residing in an area where the water supply is contaminated with herbicides and pesticides, you should stick to reverse osmosis only. Only RO is the water treatment method that can resolve your water issues in this case.

If you’re worried about the lack of minerals in reverse osmosis treated water, remember that there are always several ways to remineralize water.

It is also a fact that most mineral requirements of the human body are tended to by the food intake, i.e. the minerals that are necessary for us are present in the food we consume and is not much dependent on our water intake.

Ensure you are consuming freshly treated reverse osmosis water and keeping up with your hydration needs.
