Reverse osmosis water systems are one of the most efficient ways of getting clean, safe water for your household. If we compare them to other water filter solutions, they compare very favourably, often removing up to 99% of the contaminants in the water. We\u2019ve put together some helpful information about what this system is, key characteristics to look out for and a list of ten of the best systems to buy. Our Top Picks Best Reverse Osmosis Systems of 2020 Water Distillers that are worth mentioning We understand that it can sometimes be quite overwhelming trying to work out what system to buy, with so many options out there. As a result, we\u2019ve done the research and put together a list of 10 great reverse osmosis systems that would be a great addition to your households water system. 1. Home Master Artesian \u2013 Full Contact Reverse Osmosis Water Filtration System We start off with a fantastic reverse osmosis system that removes up to 98% of harmful contaminants from your water supply, including chemicals, metals and other minerals. It achieves this through a patented full contact technology which remineralises the water twice, allows for better-tasting water and a longer-lasting product. This product offers lots of upgrades and the option of a second faucet, with more than 10 types to choose from (for those that didn\u2019t realise - a reverse osmosis system requires its own tap). The filters are reported to last up to 2,500 gallons, so depending on your households water usage, we recommend changing filters at least once per year. 2. iSpring RCC7AK Under Sink Reverse Osmosis System This system is hard to beat, with an incredible removal of up to 99% of contaminants and other bacteria in your water supply, as well as reducing the fluoride. This is in part to its interesting six-stage filtration system that uses the first five filters to remove harmful content and the final stage actually restores a lot of the good minerals back into the water for improved health and improved taste. The other reason we like this product from iSpring is that it is fairly simple to install, compared to some of the other reverse osmosis systems on the market. The instructions are clear, minimal tools are required and the customer support is pretty good. On top of that, once installed, it only took moments to flush the system and have it ready for your family to start getting healthy, clean filtered water. 3. Quality Water Treatment SoftPro GREEN RO System The next reverse osmosis system on our list really does live up to its claim to being green, with an impressive efficiency that you will struggle to beat with the other models. On average, systems will have a waste rating of approximately 3-4 gallons, whereas the ratio for this one is closer to 1:1, which means that for each gallon of water that is purified, only 1 gallon is wastewater. A fantastic improvement for both the environment and your water bills. Away from the wastewater improvements, its 5 stage filtration offers up to 96% removal of any contaminants in the water supply, and so it still offers a fantastic tasting clean water solution. You can also get a different version that uses an alkalizing filter which improves the pH level. Finally, the manufacturer\u2019s warranty is for five years, so it is a safe investment over the long term and we\u2019ve found that the installation is relatively straight forward and can be done without professional assistance. 4. Waterdrop Reverse Osmosis System If we were to tell you this product is a space-saving reverse osmosis solution that still offers industry-leading filtration levels and great features, then you\u2019d think what a great deal. Well, you would be right! As a result of not having a tank, it is a fantastic compact solution that features displays for easier monitoring of water quality and TDS. Following the theme of great design, the installation is fairly simple and the filter changeovers shouldn\u2019t cause you much bother with a simple removal and replacement system in place. The only real downsides we can find with this model is that it doesn\u2019t improve the pH level and requires a 30 minute flush after installation before it can be used - not exactly deal breakers but good to know. 5. APEC ROES PH75 6 Stage Reverse Osmosis Water System Another on our list that offers a 6 stage filtration process including the final stage of adding in healthy minerals, creating a better tasting, healthier product for your family to drink. A reasonably priced reverse osmosis system with a good wastewater ratio and filters that are long-lasting, it should be one to consider for anyone purchasing such a filtration system. When we say the filters are long-lasting, it is important to note that the ones that come with the product are limited to around 6 months but subsequent ones state they can be changed every 2 to 3 years, with the water neutraliser lasting an incredible 4 to 6 years. All of this is dependant on the type of water your household has access to of course, but still, these are fantastic statistics. In terms of installation, we\u2019ve found this product is supplied with detailed instructions, video guides and plenty of advice out there from customers who have successfully installed the system. 6. Home Master HydroPerfection RO Water Filter System The Home Master HydroPerfection is another reverse osmosis system that offers up to 99.9% removal of microorganisms and approximately 98% of chemicals and metals, along with nicer tasting water. Where this product stands out from the crowd is with its Fast Flow technology, designed to improve the water flow by on average, double the amount compared to normal systems. This really does stop the frustrating issue of low pressure and slow flow rates, without reducing its effectiveness. Add into that a purify to waste ratio of 1:1, long-lasting filters that work for a good year before needing to be replaced and you\u2019ve got a product to shortlist. We like the fact that this manufacturer allows you to customise your order by upgrading the faucet, not simply sticking you with the boring, standard design, as well as offering a strong 5-year manufacturers warranty on the system. 7. iSpring RCC7 5 Stage Reverse Osmosis System Another system on our list from iSpring, one of the giants in water filtration, is the RCC7. At the cheaper end of the range, it still boasts an impressive 5 filter system that provides your household with safe, clean water for drinking and cooking. Following in the footsteps of the majority of reverse osmosis systems on our list, the efficiency ratio is far better than the industry standard. This model sees an average ratio of 2.5:1, offering significant savings in both wastewater and energy bills, as well as helping protect the environment. We also love the customer support that iSpring provides, with clear and simple instructions for installation, as well as video tutorials and a great customer service line to help. 8. Express Water ROALK10DCG 10 Stage Reverse Osmosis System You will instantly notice the headline here - a 10 stage reverse osmosis system from Express Water. Like us, you may well be a bit sceptical of this, so let us explain what it all means. Firstly, the majority of manufacturers believe the remineralisation part of the process is a sixth step, with the first five being filtration. Where this company differs is that they view the remineralisation as multiple steps, hence the 10 stages. Whatever they want to call it, all you need to know is that they offer a filtration system that removes up to 99% of harmful contaminants, as well as a remineralisation step that creates healthier, better-tasting water. Throw in a superb water efficiency os 2:1, easy installation process and colour coded pieces to make life easy, and you\u2019ve got a great choice for your home reverse osmosis filter system. 9. Brondell H2O+ Circle Reverse Osmosis Water Filter We really do love the design on this reverse osmosis system, with its stylish and compact design allowing it to fit in far tighter cupboards and sink areas compared to many of the others. Furthermore, they supply a chrome finished faucet with an LED light to signal when a filter needs replacing, a far nicer touch than some of the basic faucets offered elsewhere. You\u2019re not stuck with their standard faucet though and you can connect others to this system, but it is important to contact them and confirm the model you have chosen is compatible. This leads on to one of the downsides we\u2019ve found with this model and that is the filters seem to be harder to source than other brands, and in general with less availability, comes higher prices, so its good to add this into your decision-making process. 10. APEC ROES 50 5 Stage Reverse Osmosis Water System The last on our list but by no means the least is another budget-friendly model, this time from APEC, who have delivered a five-stage filtration system that still has an efficiency of 3:1. This is still above average but not quite up to the standard of some of the other models on our list. You still get the same, high-quality filtration system and it will remove the majority of harmful minerals in your water supply. The cost-effectiveness doesn\u2019t stop at the initial purchase, as APEC provides replacement filters at very reasonable prices, meaning over the long term it is even more budget-friendly compared to other systems. As an added bonus, replacement filters come with the system, so you will be unlikely to need more for another year or so. Installation instructions are clear and in detail, with images to support each step. Summary Reverse Osmosis water filters are a fantastic solution for any household waiting clean, safe and healthy water. Efficiencies in water wastage and filtration are being improved all the time, so the majority on the market will offer cost savings in the long term, as well as helping protect the environment, which is a win for everyone. We hope the information on this page has helped you take a step closer to getting a water filtration system that works for you. What is a reverse osmosis system? We will all have heard of water filters for the home or office, particularly if you live in an area with a poor water supply or particularly hard water. A reverse osmosis system is a way of purifying water by the passing of contaminated water through a semipermeable membrane using pressure, that then removes harmful minerals and contaminants. It is this membrane that blocks molecules above a certain size from getting through. Where a reverse osmosis system stands out from the crowded field of water filter systems, is in its ability to filter out far smaller particles in the water, such as molecules, bacteria and even salt. As a result, this type of system is a popular choice for industrial processes such as treating wastewater, recycling and even energy production. What you should consider Whilst you may have heard of reverse osmosis, it is important to understand some of the key characteristics of these systems, so you know what to look out for when buying one for your household. System Storage In general, a reverse osmosis system should be installed under the sink and requires space for all of the components including the tank. As a result, you will need to measure your storage space and work out early on whether a reverse osmosis system is a solution for you. If not, then there are plenty of other options to go for, especially for those households lacking much space. Water Pressure This is a very important point to note - if the water pressure at your property is under 40PSI, then you need to increase the water pressure in order to effectively use a reverse osmosis system. Some systems come with a booster pump, or you can buy one separately, that will help resolve this. If however, the water pressure doesn\u2019t improve with a booster, then you need to look at an alternative solution. Water Usage A reverse osmosis system isn\u2019t particularly easy on the water usage front and this is putting it mildly. These systems do use large amounts of water because they drain so water during the filter process because the harmful minerals are drained away using more water than feeds through to your tap. If wastewater is an issue or simply not an option, you will need to have a rethink. Replacement Filters Any type of water filter system you choose for your house will require regular maintenance and filter replacements. For reverse osmosis systems, this is a slightly more complex process because it has multiple filters to keep track of. Furthermore, this obviously increases the cost both initially and over the lifespan of the system. Water Source This is less of an issue in more urban and developed areas but if you live in remote areas that rely on water from a well, you may find this solution unsuitable due to how much water is required for it to work, as well as the pressure required.
