Waterdrop X Series X8 Reverse Osmosis System

The system measures 18.2 inches deep, 6.25 inches wide, and 16.72 inches high. Its tankless design is significantly more compact than traditional RO systems, but you should measure your cabinet space to ensure you have enough clearance for the unit and the necessary plumbing connections.

Yes, the smart faucet connects to the main unit to display real-time TDS (Total Dissolved Solids) readings. This feature provides immediate feedback on your water quality and filter status, so you always know exactly when it is time for a replacement.

This ratio means that for every two cups of pure water produced, only one cup of water is sent to the drain. This is significantly more efficient than older reverse osmosis systems, which often waste three to four times that amount, making it a much more sustainable choice for daily use.

The X8 is designed for straightforward installation, and many homeowners complete the setup themselves. However, because it requires connecting to your existing water supply and drain line, you should feel comfortable working with basic plumbing tools; if you are unsure, a professional plumber can typically install it in under an hour.

The main RO filter is rated for a 24-month lifespan or 2,200 gallons of water. While actual filter life depends on your local water quality and daily usage volume, the electronic indicator on the faucet will alert you well in advance so you are never caught off guard.

Reverse osmosis is a highly effective filtration method that removes nearly all dissolved solids, including minerals like calcium and magnesium. If you prefer mineralized water, you may want to consider adding a remineralization stage or ensuring your diet provides these nutrients from other sources.
