Additionally, the reverse osmosis system ensures that up to 99% of contaminants are removed, providing ultra-clean and great-tasting water for drinking and cooking. The system is relatively easy to install and requires minimal maintenance, promising long-term reliability and quality water supply. However, it does require a drain line for installation, which might be a limitation for some users.
