Reverse osmosis systems remove contaminants and bacteria from your tap water. They’re often a great choice for families with contaminated water and for those who are looking to get rid of lead and other hard-to-treat metals.
When it comes to deciding which reverse osmosis system is best for your home, there are several important factors to consider. One of the most important is whether you want a storage tank or a tankless system.
1. Brondell H2O+ Circle
The Brondell H2O+ Circle is a compact, best reverse osmosis system. Its patented Smart Valve and unique circular reservoir eliminate back pressure resulting in a substantial reduction in wastewater, up to 10 times more efficient than standard RO systems.
This system also saves you money by reducing your water bill because it is less wasteful than traditional RO systems. Other features include a space-saving design, LED filter life indicator, and automatic membrane flushing.
The Brondell H2O+ Circle uses 3 advanced filters to reduce harmful contaminants like VOCs, chlorine, fluoride, heavy metals, cysts and industrial chemicals in your water. The filters are easy to replace and the faucet has a filter change indicator.
2. Waterdrop G3 P800
The Waterdrop G3 P800 is an under sink RO system that meets the needs of a big household or small business. It has a large capacity and produces filtered water quickly.
Its tankless design is also space-efficient, taking up less than the counter space of a traditional tank system. Its innovative technology saves water, too, with a remarkable 3:1 filtration ratio.
It has a seven-layer reverse osmosis membrane that removes dissolved solids like salt, chlorine, arsenic, and fluoride. It also has a carbon block filter and a scale inhibitor membrane that reduces hardness minerals and effectively removes water scale.
3. NU Aqua Systems TMHP HydroPerfection
Aside from removing contaminants like chlorine, lead, chromium 6 and more from the water, the NU Aqua Systems TMHP HydroPerfection also offers remineralization to enhance the taste. This system produces up to 75 gallons of filtered water each day and features larger fittings and tubing to increase the flow rate of the water.
Compared to standard reverse osmosis systems, the NU Aqua System TMHP HydroPerfection wastes only 0.25 gallons of water per gallon of purified water thanks to a pressure pump. It’s a great choice for people who want a better quality RO unit and one that will save them money on water bills!
This countertop reverse osmosis system is easy to install, requires no professional plumbing skills and doesn’t require drilling. Filters last between six months and two years and are easy to replace without tools (the unit will tell you when it’s time to do so).
4. iSpring RCC7AK-UV
If you’re looking for an efficient RO system that produces less than 2 gallons of wastewater for every gallon of pure water, then the iSpring RCC7AK-UV is a great option. This unit is certified to NSF/ANSI 58 standards and has a flow sensor that turns the UV light on automatically when water flows through it.
It has a dual tank design to separate the membrane and filter media. It also has an efficient 7-stage filtration system that removes up to 99% of contaminants, including arsenic, asbestos, lead (removes up to 98%), chlorine, fluoride, sodium and more.
The iSpring RCC7AK-UV also has an alkaline remineralization filter that returns healthy minerals to your water to help balance the pH and improve its taste. It also includes a UV ultraviolet stage that kills all the living microorganisms, viruses and bacteria.
5. Frizzlife PD-600-TAM3
The Frizzlife PD-600-TAM3 is a tankless reverse osmosis system with multi-stage filtration and alkaline remineralization. It removes chlorine and other contaminants, adds back alkaline minerals, and helps to improve the taste of water.
It also features smart life indicators and a filter cartridge that only needs to be replaced once per year. This makes it very cost-effective and a great choice for the environment.
The system has 7 stages of filtration, including a pleated sediment filter, high-grade ACF1 and ACF2 media, an RO membrane, a coconut carbon block filter, and an alkaline remineralization filter. It has a 500 GPD flow rate and a 1.5:1 efficiency ratio.
