Reverse osmosis is one of the most widely used water-treatment technologies for producing highly filtered drinking water at home. But before buying or maintaining an RO system, homeowners often have questions about safety, contaminants, minerals, water waste, maintenance, pressure, and cost. This guide answers the most common reverse osmosis FAQs in one place. If you’re […]

Reverse Osmosis Buying Guide: How to Choose the Best RO System for Your Home
Buying a reverse osmosis system can be confusing. There are tank-based systems, tankless systems, countertop units, systems with booster pumps, remineralization filters, UV stages, different gallon-per-day ratings, and a wide range of contaminant-reduction claims.
Continue readingDo You Need Reverse Osmosis? How to Decide if an RO System Is Right for Your Home
Do you need reverse osmosis? Not necessarily. Reverse osmosis (RO) is one of the most capable point-of-use water-treatment technologies available for reducing a broad range of dissolved contaminants. But that doesn’t mean every household needs an RO system. The right answer depends on what is in your water, what you want to remove, and which […]
Continue readingWhy Reverse Osmosis Removes Contaminants: How RO Water Filtration Works
Reverse osmosis is one of the most effective technologies available for reducing a wide range of contaminants from drinking water. But why does reverse osmosis remove contaminants when ordinary filters cannot? The answer lies in the way an RO system combines pressure, a semipermeable membrane, selective separation, and multiple stages of filtration. Unlike a conventional […]
Continue readingIs Reverse Osmosis Water Healthy? What You Need to Know
Is reverse osmosis water healthy? Yes. For most people, drinking water produced by a properly maintained reverse osmosis (RO) system is considered safe and can be an excellent way to reduce many contaminants found in drinking water. Reverse osmosis removes or substantially reduces a broad range of dissolved substances, including certain metals, salts, nitrate, fluoride, […]
Continue readingIs Reverse Osmosis Water Safe? What You Need to Know Before Drinking RO Water
Reverse osmosis, commonly called RO, is one of the most effective household water-treatment technologies available. It can reduce a wide range of dissolved contaminants, including many heavy metals, salts, inorganic compounds, and certain organic chemicals. The EPA describes reverse osmosis as a membrane process capable of removing a broad range of contaminants from drinking water. […]

Clean drinking water is essential for good health, but water can sometimes contain microbial contaminants—microscopic organisms capable of causing illness. These contaminants include bacteria, viruses, protozoa, and other microorganisms. Microbial contamination is particularly important because even relatively small amounts of some disease-causing organisms can create a health risk. EPA states that for microbial contaminants that […]
Continue readingBacteria and Viruses in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
Bacteria and viruses are among the most important biological contaminants that can affect drinking water. Unlike many chemical contaminants, microorganisms can multiply or spread rapidly and may cause illness after relatively short-term exposure. Potential sources include human and animal waste, sewage, agricultural runoff, failing septic systems, flooding, contaminated groundwater, and problems within water distribution systems. […]
Continue readingPharmaceuticals in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
Pharmaceuticals in drinking water are an emerging water-quality concern. Trace amounts of prescription drugs, over-the-counter medications, and veterinary pharmaceuticals can enter rivers, groundwater, reservoirs, and wastewater streams and, in some circumstances, be detected downstream of treatment facilities. The important distinction is that detecting a pharmaceutical in water does not automatically mean the water is unsafe […]
Continue readingPesticides in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
Pesticides play an important role in agriculture, landscaping, pest control, and public-health programs, but some pesticide chemicals can enter drinking-water sources through agricultural runoff, groundwater contamination, stormwater, and other pathways. Whether pesticides in drinking water present a health concern depends on which pesticide is present, how much is present, and how long people are exposed. […]
Continue readingMicroplastics in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
Microplastics have become an increasingly important drinking-water concern as researchers continue to detect tiny plastic particles in tap water, bottled water, rivers, groundwater, and other parts of the water cycle. Unlike contaminants such as lead, arsenic, or nitrate, microplastics are particles rather than dissolved chemicals. Their size, shape, polymer type, and surface characteristics can vary […]
Continue readingNitrites in Drinking Water: Health Risks, EPA Limits, Testing & Filtration
Nitrite is a nitrogen-containing chemical that can occur naturally in the environment but is more commonly associated with fertilizer runoff, wastewater, septic systems, animal waste, and the biological conversion of nitrogen compounds. Although nitrite and nitrate are closely related, they are not the same chemical. Both are regulated in drinking water because elevated concentrations can […]
