Tank vs. Tankless Reverse Osmosis: Which One is Better?

If you want to make sure that your home has clean, safe drinking water, a reverse osmosis(RO) system is an ideal choice. However, when you are selecting a system, whether there are tanks or not, needs some major consideration. Both kinds of RO systems have their advantages and disadvantages. We will detail the differences and help you make up your mind about which one is best for you.

Space Requirements

  • Tank RO Systems: These systems come with a storage tank for the filtered water. While this is great for storing water, it does take up a bit more space.
  • Tankless RO Systems: Without a storage tank, tankless systems are much smaller and more compact. Perfect for homes with limited space.

Noise Levels

  • Tank RO Systems: These systems are generally quieter. The system only runs when the tank needs to be refilled, meaning less noise.
  • Tankless RO Systems: Since they filter water on demand, tankless systems may run more frequently, which can lead to louder pump noises.

Water Flow Speed

  • Tank RO Systems: With a storage tank, water can flow quickly from the faucet since the water is already stored and ready to go.
  • Tankless RO Systems:Because these systems filter water as you need it, the flow may be a bit slower compared to tank systems.

Reliability

  • Tank RO Systems: Since tank systems don’t run as often, they experience less wear and tear and tend to last longer.
  • Tankless RO Systems: These systems are under more stress because they work more often, which can lead to quicker wear and tear over time.

Winner: Tank systems are more reliable in the long run.

Hygiene

  • Tank RO Systems: They require regular maintenance to clean the tank, or bacteria can build up inside it.
  • Tankless RO Systems: With no tank, there’s less risk of contamination, making them more hygienic.

Cost

  • Tank RO Systems: Generally, tank systems are more affordable to purchase, install, and maintain. They also have cheaper filter replacements.
  • Tankless RO Systems: Tankless systems are more expensive upfront, as they use advanced technology. Additionally, their filter replacements tend to be pricier.

Handling Water Demand

Tank systems are great for handling high water flow, as they store water for immediate use. Tankless systems, on the other hand, rely on powerful pumps to meet peak demand, which can increase costs and wear out the system faster.

Which One is Right for You?
