Reverse osmosis filters are first-line filters for removing a large percentage of contaminants from water, which can include dangerous waterborne bacteria. The filters work by pushing water through the reverse osmosis membrane using pressure. Perhaps the most effective type, reverse osmosis (RO) units force water through a multi-stage filtration process. The first stage is a sediment pre-filter, designed to remove larger particles (such as sand and silt).

Next is a charcoal filter to remove organic contaminants, including those that affect the smell and taste of water. Last but not least, a semipermeable membrane handles chemical contaminants. In some reverse osmosis filters, there is even a fourth and final “polishing” stage. The inconvenience? Reverse osmosis filters do nothing to mitigate the presence of microorganisms.

A reverse osmosis system is the most effective type of filter for drinking water. Many of them have seven or more filtration stages, along with the osmosis process, which makes them effective in removing 99 percent of contaminants from water, including chemicals, such as chlorine, heavy metals, pesticides and herbicides. Some reverse osmosis systems even add healthy minerals and nutrients to water. If you're using water from a private well, or water whose quality you're not so sure, there are several ways to check if it's safe.

It's ideal for filtering drinking water for singles or small families and is small enough to take to the office or when traveling. A number of customers say the dispenser was very easy to set up and operate, although some point out that it takes some time to filter the water. The entire unit weighs just 15 ounces, making it light enough for hiking, and each cartridge can filter up to 500 gallons of water. However, the AquaHomeGroup filter remains an excellent (and easy) solution for irritation of brittle and falling hair and skin caused by ordinary water.

CDC has a wealth of information to help you decide what type of water filter is best for your home. While there are a variety of water filtration systems, no type is inherently better (or worse) at filtering contaminants. Filters certified to remove chlorine, for example, can also promote hydration by making water more pleasant to drink. The Sawyer Squeeze filter is one of the best companions you can have for a backpacking trip in the woods, mountains or any corner of the world where water quality cannot be taken for granted.

Multistage reverse osmosis systems with seven stages of filtration can produce the purest water you can drink, but the cost of replacing seven different filters can quickly increase. With physical filtration, water is filtered through a membrane layer, which captures particles and prevents them from entering the purified water. Therefore, if your filter needs to be replaced every six months, NSF will test each filter to ensure a six-month lifespan. Unlike some bulky water filtration systems, the Brita water jug has a refrigerator-safe design, measures 10.7 by 5.4 inches and weighs 1.3 pounds.

You can get an affordable water filter for personal use without breaking the bank, but be sure to look for certifications.
