The Ultimate Buying Guide: Reverse Osmosis Drinking Water Filter System
Are you tired of tap water that tastes funny or makes you worry? A Reverse Osmosis (RO) drinking water filter system might be just what you need! This guide will help you understand what to look for when buying one and answer common questions.
What is Reverse Osmosis?
Reverse Osmosis is a fancy way of saying “super filtration.” It uses pressure to push water through a very fine membrane. This membrane traps impurities like salt, lead, chlorine, and other yucky stuff, leaving you with clean and great-tasting water.
Key Features to Look For
When shopping for an RO system, keep these features in mind:
- Number of Filtration Stages: More stages usually mean cleaner water. Most systems have 4 or 5 stages. These stages include sediment filter, carbon filter, RO membrane, and sometimes a post-carbon filter for improved taste.
- Filtration Capacity: This tells you how much water the system can purify per day, usually measured in gallons per day (GPD). Choose a system with enough capacity for your household’s needs.
- Tank Size: RO systems store purified water in a tank. Consider how much storage you need based on how often you use filtered water.
- Certifications: Look for certifications from organizations like NSF International. This means the system has been tested and meets certain standards for safety and performance.
- Automatic Shut-Off Valve: This feature stops the system from producing more water when the storage tank is full, preventing waste.
- Easy Installation: Some systems are easier to install than others. Read reviews or look for systems with clear instructions and included installation kits.
- Warranty: A good warranty shows that the manufacturer stands behind their product.
Important Materials
The materials used in an RO system affect its durability and performance.
- Housing: Look for housings made from durable, food-grade plastic.
- Fittings: High-quality fittings prevent leaks. Stainless steel or durable plastic fittings are good choices.
- Membrane: The RO membrane is the heart of the system. Look for membranes made from high-quality materials and with a good reputation.
- Storage Tank: Tanks are usually made of plastic or steel. Ensure the tank is food-grade and won’t leach any harmful substances into the water.
Factors That Improve or Reduce Water Quality
Several factors impact the quality of water produced by an RO system:
- Source Water Quality: If your tap water is heavily contaminated, the RO system might need to work harder, and the filters might need to be replaced more often.
- Filter Maintenance: Regularly replacing the filters is essential for maintaining water quality. Follow the manufacturer’s recommendations for filter replacement.
- System Design: A well-designed system with multiple stages of filtration will generally produce better-quality water.
- Water Pressure: The RO system needs adequate water pressure to function correctly. Some systems may require a booster pump if your water pressure is low.
- Membrane Quality: A high-quality membrane will remove more contaminants and last longer.
User Experience and Use Cases
RO systems are great for:
- Improving Water Taste: They remove chlorine, sediment, and other impurities that can make water taste bad.
- Removing Harmful Contaminants: They effectively remove lead, arsenic, and other harmful substances from your drinking water.
- Making Ice: RO water makes clear, great-tasting ice cubes.
- Cooking: Using RO water in cooking can improve the flavor of your food.
- Baby Formula: Many parents prefer to use RO water for preparing baby formula.
The user experience is also important. Look for a system that is:
- Easy to Install: Even if you hire a plumber, an easy-to-install system will save you time and money.
- Easy to Maintain: Look for systems with easy-to-replace filters.
- Quiet: Some systems can be noisy. Read reviews to see what other users say about the noise level.
