Your Guide to Whole House Reverse Osmosis Water Filters
Why Choose Whole House RO?
Are you tired of bottled water? Do you want cleaner, safer water for your whole home? A whole house reverse osmosis (RO) system is a great choice. It filters all the water that comes into your house. This means your drinking water, shower water, and even water for your appliances will be cleaner. It removes many impurities like chlorine, lead, and bacteria.
Key Features to Look For
- Filtration Stages: Most systems have multiple stages. Look for systems with at least 4 or 5 stages. This usually includes sediment filters, carbon filters, and the RO membrane.
- Flow Rate: This is how much water the system can filter per minute. Make sure the flow rate is high enough for your household’s needs.
- Storage Tank Size: RO systems need a storage tank. A bigger tank means you have more filtered water ready to use.
- Remineralization Stage: RO membranes remove minerals, which can affect taste. A remineralization stage adds back healthy minerals like calcium and magnesium.
- Pressure Tank: This helps push the filtered water through the system.
Important Materials
What Makes a Good System?
The materials used in the filters and housing matter. Look for:
- Food-Grade Plastics: The housing and tanks should be made of safe, durable plastic that won’t leach chemicals into your water.
- High-Quality Filter Media: The sediment and carbon filters should be made of good materials. This helps them capture more contaminants.
- Durable RO Membrane: The RO membrane is the heart of the system. A good membrane lasts longer and filters more effectively.
What Affects System Quality?
Improving and Reducing Quality
Several things can make your RO system work better or worse.
- Water Pressure: RO systems need good incoming water pressure to work well. If your pressure is low, you might need a booster pump.
- Maintenance: Regularly changing the filters is crucial. Dirty filters can slow down the system and reduce water quality.
- Pre-filtration: A good pre-filter protects the RO membrane from sediment and chlorine. This makes the membrane last longer.
- Installation: Proper installation is key. If it’s not installed correctly, it might not work as well or could leak.
