How We Rated the Products

Now let’s find out more about how the products were rated. When we looked for the best osmosis systems, we thoroughly analyzed their performance and durability, just to make sure you pick the appropriate model for your needs. Therefore, we took into consideration the most important aspects of this type of system, including how much water it can filter and what contaminants it can eliminate.

  • Dimensions

    Although not an essential characteristic, the size of a RO plays a significant role if you don’t have too much space available. Considering the fact that these systems are usually designed for under countertop installation, we tried to select the models that feature a compact design. Home Master TMAFC is the only exception as is a little bit larger than the other models. However, its dimensions don’t pose any serious problems as it fits most standard under sink cabinet sizes. Nevertheless, is always good to measure how much space your future system takes to avoid any unpleasant situations.

  • Faucet Included

    When the system you buy includes a faucet, it simply means that you will save more money. There are many manufacturers that include a faucet dispenser and all the necessary parts for installation, just to make sure you get all you need without losing time or money. Some of them even offer you the possibility to choose from more faucet colors, such as Pelican Water or Aquasana. Therefore, Pelican Water PRO-RO-PC Pro 6-Stage comes with a Polished Chrome Faucet but you can opt for Brushed Nickel or an Oil Rubbed Bronze faucet. Aquasana OptimH2O includes a Brushed Nickel faucet, but for more money, you can choose a Chrome Metal or an Oil Rubbed Bronze faucet.

  • Daily Production

    The daily production or the membrane capacity for a home reverse osmosis system is measured in gallons per day (GPD). The production estimated by the manufacturer can be affected by many factors, including water pressure, temperature, pH, and so on. For enjoying superior results, you have to always follow the manufacturer’s requirements in terms of water because otherwise you may be disappointed with the system performance. If you take a closer look at our comparison chart, 3 models feature a daily production of up to 50 gallons per minute. The only exceptions are Aquasana OptimH2O with a maximum production of 35 gallons per day and iSpring RCC7 that can filter up to 75 gallons per day.

  • Contaminates Removed

    Since the main purpose of a RO system is to remove the common tap water contaminants and to deliver unlimited clean water, it is only natural to know more about this aspect. All the models selected by us can effectively reduce more than 60 contaminants, including chlorine, copper, lead, and so on. The reduction percentage is up to 99% or even 100% in some cases, which is quite impressive. This means you will no longer have to worry about the possible health risks you expose to when drinking unfiltered tap water.

  • Number of Filters and Stages of Filtration

    More filters doesn’t necessarily mean more efficiency, so you shouldn’t be fooled by this information. There are many systems that deliver superior performance with only 3 filters, such as Aquasana OptimH2O and Home Master TMAFC. The model with the most filters included is Pelican Water PRO-RO-PC Pro 6-Stage. All our models come with quality filters that have been previously tested and are designed for longevity. In general, a good RO system features a sediment filter to remove dust and particles, a carbon filter to eliminate bad tastes, odors, and chemicals, and a RO membrane to remove the common contaminants like lead, fluoride, arsenic, etc. Additionally, some systems come with a postfilter that replaces beneficial minerals back into the water for good taste and nourishing properties. The systems with a remineralizer filter are Pelican Water PRO-RO-PC Pro 6-Stage, Aquasana OptimH2O, and Home Master TMAFC.

  • Warranty

    For more peace of mind, a reverse osmosis water filtration system should be covered by a longer warranty. Unfortunately, most units come with a standard 1-year warranty, like Pelican Water PRO-RO-PC Pro 6-Stage and APEC Top Tier 5-Stage. The models with a longer warranty are iSpring RCC7 and Home Master TMAFC. The first one is backed for 3 years, while the second one for 5 years.

Health Risks of Drinking Contaminated Tap Water

To better understand the advantages of the water filtration systems, let’s see which are the possible health risks you expose to when drinking contaminated water. Taking the necessary measures to prevent all sorts of dangers is the wisest thing you can do. Here is what specialists say:


  • Thyroid Disorders: Water that contains fluoride can seriously affect thyroid gland. This is possible due to the fact that fluoride can suppress thyroid function, being considered an endocrine disrupter.
  • Skin Affections:Many water supplies in the U.S.A. contain high arsenic levels and this chemical contaminant is known for causing all sorts of skin affections. Additionally, some specialists say it is a carcinogen.
  • Neuromuscular Disorders:Water supply contain lead which can cause neuromuscular disorders. This metal is very toxic, so is best to eliminate it as much as possible. Once present in the body, lead can cause fatigue, concentration difficulties, or even severe brain damage.
  • Cancer and Birth Defect: Although there are many contaminants that can be associated with cancers, one of the most dangerous ones is chlorine. While it’s true that chlorine can destroy many of the pathogens in water and lower the chances to develop waterborne diseases, it is also very dangerous. It is linked to various cancers like rectum, breast, or threat cancer.


Best Brands to Consider

Although there are many RO systems available, not all of them deliver the same performance. For this reason, opting for a leading brand is an assurance that you won’t invest your money in a poor-quality system. In the water purification market industry, brands like Pelican Water, Aquasana, or Home Master are very popular because they design and manufacture innovative water filtration systems for every house.

  • Pelican Water
