Reverse Osmosis (RO)

Reverse osmosis (RO) water filters are advanced filtration systems that remove a wide range of contaminants from water by forcing it through a semi-permeable membrane. This process effectively eliminates impurities such as dissolved salts, heavy metals, chlorine, fluoride, bacteria, and other harmful substances. RO systems typically include multiple stages of filtration, often starting with sediment and carbon pre-filters to protect the membrane, followed by the RO membrane itself and a post-filter to polish the final water. The result is clean, purified water with improved taste and safety, making reverse osmosis a popular choice for households seeking high-quality drinking water. ROs can remove components that other filters cannot (see FAQs)

FAQs

What can an RO remove from water?

Reverse osmosis (RO) filters remove a broader and more precise range of contaminants than most standard filters. While basic filters like carbon or sediment cartridges remove chlorine, bad taste, odors, and larger particles such as rust or sand, RO filters go further by targeting dissolved solids and microscopic contaminants that other filters can't.

Here’s what RO removes that standard filters typically don't:

  • Dissolved salts and minerals (e.g sodium, calcium, magnesium
  • Heavy metals like lead, arsenic, mercury and chromium
  • Fluoride
  • Nitrates and sulfates, common in agricultural runoff
  • Microorgansism, such as bacteria and some viruses (in combination with a post-filter or UV ligth, depending on the system)
  • Pharmaceutical residues and volatile organci compounds (VOCs) to a greater extenet than most fitlers

This makes RO systems especially effective for areas with poor water quality or specific health-related filtration needs

Is reverse osmosis water safe to drink?

Yes, RO water is safe to drink and often much cleaner than tap water. Some people choose to remineralize it after filtration because the process also removes beneficial minerals like calcium and magnesium.

Is reverse osmosis better than other filtration methods?

It depends on your water quality and needs. RO provides more thorough filtration than standard carbon or sediment filters, making it ideal for areas with high contamination levels or for people with specific health concerns.

How often do RO filters need to be replaced?

RO systems have multiple filters with different lifespans. Pre-filters and post-filters typically need to be replaced every 6–12 months, while the RO membrane usually lasts 2–3 years, depending on water quality and usage.
