A Reverse Osmosis Water Filter is great for those who want to remove as many impurities from their drinking water as possible and perfect for those who don’t like the smell and taste of chlorine and want to avoid fluoride at all costs.

Here are the Pros and Cons of Reverse Osmosis Water Filters:

Pros of Reverse Osmosis Filters

Removes The Most Amount Of Contaminants Of All Water Filter Options

Of all the filtration methods available, Reverse Osmosis removes the most contaminants and creates healthier drinking water for the whole family.

Cheaper Than Bottled Water

Our article, Bottle Water VS Filtered, outlines how much money can be saved by choosing filtered water over bottled water. Bottled Water is overrated!

Makes Food Taste Better

Reverse Osmosis removes all taste and odour from water, so when you cook with filtered water, the flavours in your food can shine.

Most effective water filtration available for Fluoride Treatment

Of the water filters on the market, Reverse Osmosis Water Filters are the only proven method and the most effective treatment against Fluoride.


A good quality, middle of the range Reverse Osmosis Water Filter is around about $400-500. Which is super cheap if you think about the type of protection it gives the health-conscious family.

Removes Chlorine and Fluoride

No more worrying about ruining your gut microbiome with chlorine or messing up your thyroid due to fluoride. RO systems are effective at removing both of these terrible water contaminants.

Nicer Tasting Water

When water is pure, without pollutants or dissolved substances, it’s much nicer to drink.

Cons of Reverse Osmosis Filters

Requires Occasional Maintenance

Sometimes chlorine can clog the reverse osmosis membrane, making the pre-filter more critical.

A pre-filter is designed to remove some chlorine before the water reaches the reverse osmosis membrane.

Slower Water Production Than Other Filters

Reverse Osmosis takes longer than most other filtration methods because it undergoes the RO process.

Removes Essential Minerals

Because Reverse Osmosis removes practically everything from the water, it also removes all of the good stuff. In other words, essential minerals such as calcium, magnesium and salt, required for the body to function properly, are removed during the filtration process.

We always recommend units that include features to raise the pH after the water has been purified.

Our Top Reverse Osmosis Filter Recommendations

If you require a Benchtop System for drinking, we recommend an RO 4000 Benchtop Reverse Osmosis Water Filter System with Standard Alkaline. You’ll get great tasting water with high alkalinity.

If you require an Under Sink System and are looking for pH 7 with healthy minerals, we recommend the Aquasana; If you want high alkalinity, we recommend a HPF 7 Stage Reverse Osmosis Under Sink Water Filter System. Both options create really fantastic water.
