Portable Reverse Osmosis Water Filters

How to select the best portable reverse osmosis water filters? Use this buying guide to learn more about reverse osmosis water treatment, find the top portable models and features.

Reverse osmosis water treatment (RO) is one of the most popular ways of removing the contaminants from water and making it clean and healthy to drink. RO water filters are very effective against the lead, chlorine, pesticides, cysts and many other substances that can affect the taste of water and your health.

Reverse osmosis is the most used method of water filtering, but it has several disadvantages. Permanent (i.e. undercounter) and portable reverse osmosis water filters used at home are not effective against organic substances, unless combined with other water treatment systems. Water treated by reverse osmosis is acidic, aggressive and has a flat taste so add-on cartridges should be considered.

There is a lot of wasted water as the result of the RO water treatment, but the good thing is that most impurities are flushed away. According to some websites, several gallons of water are needed to produce one gallon of RO treated water. Reverse osmosis is a slow filtration process, and it might take some time before you get enough drinking water for your home.

The best filtration systems are the combination of the reverse osmosis and other methods, such as, carbon filter, used to reduce carbon particles, and which cannot be captured by the membranes in RO systems.

How reverse osmosis water treatment works

Reverse osmosis (RO) is, according to Wikipedia, a process used in water purification that uses a membrane filtration to remove water contaminants with large molecules and ions and by applying the pressure. The membrane does not allow larger molecules of contaminants to pass through its pores but smaller water molecules.

Portable reverse osmosis water filters are known as countertop models, and these are using multi-stage method for purifying water; the best RO systems have 3,4 and even 10 phases.

Portable reverse osmosis water filters do require high water pressure for the correct water treatment. Before you buy a portable RO water filter check if the water pressure inside your plumbing system is higher than the specified working water pressure for particular RO filter. If it is lower than find another system.

Built as the portable systems, they are very simple to install and due to its compact size, easy to store.They do not require any power to operate, so they can be used when camping, but remember the minimum required pressure has to be met. Use the faucet adaptor to connect the RO water filter to the faucet, turn ON your tap water and collect filtered water into the container.
