by | Feb 21, 2025 | Water Quality, Plumbing, Water Solutions, Reverse Osmosis

Thinking about installing a reverse osmosis system in your home? Whether you’re after clean, refreshing drinking water or a compact system for your lifestyle, a reverse osmosis system is an excellent way to improve water quality. But the main question is, what does a reverse osmosis system cost?

What Is a Reverse Osmosis System?

A reverse osmosis system is a water filter that removes unwanted substances like chlorine, lead, and dirt by pushing water through a special membrane. This process leaves you with cleaner, fresher water straight from the tap.

They are great for improving water quality at home. Whether you install a reverse osmosis system under your sink for everyday use or choose a portable unit for travel, reverse osmosis gives you safe, purified water for drinking, cooking, and more.

Types of Reverse Osmosis Systems and Their Costs

At Five Star Home Services, we offer two types of reverse osmosis systems to suit different needs. These systems are a great way to improve water quality, and choosing the right one depends on your household’s requirements.

Our basic system is ideal for individuals or small households, providing clean, great-tasting water at an affordable price. For larger families, our advanced system offers superior filtration and higher capacity, ensuring pure water anytime.

Both options are competitively priced, offering great value without compromising quality. Our team can help you pick the best system for your budget and lifestyle.

Under-Sink Reverse Osmosis Systems

Under-sink systems are installed directly under your kitchen sink, providing a steady supply of purified water for your entire household. This is an excellent permanent and high-performance solution for families or those looking to improve water quality for daily use.

  • Under-Sink Reverse Osmosis System Cost: $800–$1,475 (depending on the model and features)

Portable Reverse Osmosis Systems

Portable reverse osmosis systems are compact, convenient, and made for those on the move. These systems are perfect for renters or travelers who want clean water wherever they go.

  • Portable Reverse Osmosis Systems Cost: $250–$500

What Influences Reverse Osmosis System Cost?

A reverse osmosis system is an investment in your water quality. Several factors come into play when determining total reverse osmosis system cost, from initial purchase to long-term maintenance. Here’s what you need to consider:

1. Initial Purchase and Installation Costs

The upfront cost includes the system itself and any necessary accessories. Some systems also require professional installation to get started.

At Five Star Home Services, our experts ensure your system is installed properly and efficiently, so you can start enjoying better water right away.

2. Maintenance and Filter Replacement

To maintain high performance, you’ll need to replace filters regularly. The frequency depends on your model, but most filters need to be replaced every 6–12 months.

  • Cost Per Filter: $30–$100

3. Energy Consumption

Some water systems need electricity to increase water pressure, especially in homes with low water pressure. They use a pump or similar device to help water flow better through your home. Although these systems don’t use a lot of energy, the costs can add up over time if used often. When planning your budget, it’s a good idea to think about these costs and look for energy-efficient options to save money in the long run.

4. Warranty and Service Agreements

A good warranty protects your investment and reduces unexpected repair costs. At Five Star Home Services, many of our systems come with extended warranties for added peace of mind. Not to mention, our Whole Home Protect Plan is designed to help you protect your investment.

5. Optional Features and Upgrades

Want even more from your system? Features like remineralization filters (to restore healthy minerals) or larger storage tanks can push reverse osmosis system costs higher but provide extra convenience.

Looking to combine your reverse osmosis system with a whole-house water filter? We can help you create the perfect setup.

Why Invest in Reverse Osmosis?

Installing a reverse osmosis system isn’t just about clean water—it’s about long-term value and peace of mind. Here’s why it’s worth every penny:

  • Better Water Quality: Filters impurities like chlorine, sediment, and heavy metals.
  • Cost Savings: Say goodbye to pricey bottled water.
  • Convenience: Enjoy access to fresh, clean water right from your tap.
