Our very first recommendation is a powerful and compact RO system manufactured by Waterdrop. It is one of the most reputable osmosis systems you will find in the market that is stylish, sleek, feature oriented and can easily be fixed under your kitchen sink

The Waterdrop RO Water Filtration System provides you with clean drinking water after processing it through seven stages such as a sediment pre-filter containing three stages, a 0.0001μm RO membrane that effectively removes all the harmful contaminants from the water through three internal-stages and a carbon post-filter stage.

The Waterdrop RO System is set apart from the rest of the products because of its three main features, all of them that we will be discussing in-depth one by one.

Tankless Design:

Most of the under-sink RO systems rely substantially on tanks. They keep the filtered water in their storage and that not only increases the size of the filtration system but also provides a minimum amount of water.

The Waterdrop RO Water Filtration System comes with a tankless design. It not only provides you water on demand but it also has the ability to perform instantly. The tank will keep providing you with filtered water even when most of the other water filters slow down because they have to fill the tank.

5-Times Daily Output:

If you have a big family, chances are you must be looking for an RO System that can provide you tons of water every day.

Lucky for you, the Waterdrop RO Filtration System comes with the ability to produce minimum 400 gallons per day.

While we were researching, we came across numerous systems and most of the ones that we found to be useful were only able to provide 75-gallons-per-day which was a huge setback.

With this filtration system, you will be able to provide your family with clean drinking water without having the thought of running out of it.

Real-time Feedback:

The Waterdrop RO Water Filtration Systems features an LCD ring that will provide you with all the information you need while your water is being filtered.

It comes with different colors of LEDs that will keep you updated on the status of your filtration process. The LCD screen will also report the status of the current total dissolved solids allowing you to know the level of filtered water in real time.

Most of the other filtration system require a third-party mechanism to provide the customer with TDS information while this one comes integrated with the same mechanism.

Ease Of Installation:

In fact, of all the systems that we came across and ended up testing, the Waterdrop RO System was the easiest to install.

Buying Guide For Best Reverse Osmosis Systems

Since you have read through all our recommended reverse osmosis system, it is about time we discuss the things that you really need to look for when you’re hunting for best residential reverse osmosis systems.

All our above mentioned products are ideal for small and bigger homes. Some of those products are portable while other can be easily fixed under your kitchen sink or inside a small cabinet.

Moving on, if you think those recommendations have not come close to what you have looking for, our buying guide can make up for that loss.

Here, we will be discussing sevven things that you must consider when buying a reverse osmosis system so you never regret your purchase.

Water Source

If you’re living in an urban area, you will easily be able to find a reverse osmosis system with the regular RO membrane.

But in case you’re living in rural areas where you have to use the dam or river water in your homes, you will need something far more powerful than a regular RO system.

See, the thing is, the town water supply has already been filtered through big plants so it is relatively cleaner than the water available in rural areas, thus, easier to clean in RO systems.

But the rural areas have to take water directly from the river so they require powerful RO systems to tackle the dirt present in the water.

Filter Stages

The first and foremost thing you need to consider when buying reverse osmosis system are how many filter stages does it go through.

Normally, most of the units that you find in the market comprise of 3-5 filtration stages. Each stage removes the solid contaminants from the water efficiently and provide you with clean drinking water.

So, when you’re searching for a reverse osmosis system, make sure you choose the unit that offers more than 5-stages.

The RO Membrane

The RO membrane in such filtration systems is the most important aspect and feature to consider.

The water purification process thoroughly depends on this membrane so it should be from a reputable company. Also, always check the GDP capacity of the RO membrane before your purchase it. A good quality RO system will provide you with at least 50-gallons-per-day.

Waste Water Ratio

We all know that waste water ratio against pure water is a lot, that is something we cannot control but what we can control is choose a unit that wastes as minimum water as it can.

There are numerous products available in the market that waste very less water to provide you with pure drinking water. Keep your search thorough and make sure you choose that RO system that is efficient in saving water.

Residential RO Membranes

Another thing that you need to keep in mind is that residential RO membranes can only be used to filter town supply of water. They cannot be used filter rain, dam or river water.

If you are buying a reverse osmosis system for commercial purposes where town water supply won’t be filtered, then you need to go for special RO membranes, ones that are capable of eradicating any kind of harmful contaminant from the water.

Size

We have often noticed that size is the first thing most of the buyers consider when they’re getting the reverse osmosis system they need. This is a good thing. Nobody wants to spend money on something they won’t be able to keep in their homes.

Always see how much space you have in your home and then choose the product accordingly. There are many RO systems now available in the market that come in compact sizes and still provide excellent efficiency.

Budget

Always determine your budget beforehand. You don’t want to end up in an awkward situation where you love a product but it doesn’t fall under your price range.

The best way to make the most of your budget and choose the best product under that range is by going through several brands and determine which product offers the most in the least price. This will allow you to stay ahead from the ever-changing RO industry and choose the best unit without overdoing your pocket.

So, these are the things that you need to keep in perspective when you’re looking for a reverse osmosis system. We hope this buying guide has been thoroughly helpful and now you have a better idea of what you need to look for when you’re out on a shopping spree.
