Frequently Asked Questions (FAQs)
1. What is a whole house reverse osmosis (RO) system?
A whole house RO system purifies water at the point of entry, ensuring that every tap in your home—including showers, kitchen faucets, and laundry—receives highly filtered, contaminant-free water.
2. How is a whole house RO system different from under-sink or countertop filters?
Under-sink and countertop filters only treat water at a specific outlet (usually the kitchen sink). A whole house system treats all the water entering your home, offering complete coverage for drinking, bathing, cooking, and cleaning.
3. What contaminants does a whole house RO system remove?
These systems can effectively remove heavy metals (like lead and arsenic), chlorine, pesticides, fluoride, nitrates, bacteria, viruses, and other harmful dissolved solids from your water supply.
4. How often do I need to maintain or replace filters in a whole house RO system?
Pre-filters and post-filters generally need replacement every 6–12 months. The RO membrane typically lasts 2–3 years, depending on your water quality and usage. Regular maintenance ensures optimal performance.
5. Is it worth the investment for homes with municipal water?
Yes. Even municipal water can contain chlorine, microplastics, and other residual contaminants. A whole house RO system offers an extra layer of protection and is especially beneficial for people with health concerns, sensitive skin, or a preference for ultra-pure water.
