Avalon A61-RO Reverse Osmosis System
A countertop reverse osmosis system with a TDS display
The Avalon A61-RO brings 4-stage reverse osmosis to your countertop. It connects to your water line and pours purified water at the touch of a button, with no bottles to buy.
Reverse osmosis lowers dissolved solids that a carbon filter alone cannot. A TDS display shows the purity of your water, a UV light sanitizes it, and a filter life light tells you when it is time for new filters.
Want it out of sight? The Avalon A62-RO installs under the sink with its own faucet.

Avalon A61-RO FAQs
What does reverse osmosis remove that a regular filter does not?
The RO membrane lowers total dissolved solids (TDS), the minerals and salts a carbon filter lets through. The TDS display shows the result.
Does it need a drain?
Yes. Reverse osmosis sends some water to drain. Run the included drain tube from the back of the unit to your sink drain pipe with the included clamp.
How do I pour water?
Touch the dispense button to start and touch it again to stop. After 30 seconds idle it goes to standby, and a touch wakes it up.
How often do the filters need changing?
Every 6 months or 1,500 gallons. The filter life light comes on when it is time, and the Avalon RO replacement filter set replaces all four filters at once.

- Coverage: Avalon products include a 1-year limited manufacturer's warranty from the original purchase date. The warranty ends early if the product is sold or transferred.
- Registration: Register your unit with Avalon within 30 days of purchase to activate the warranty on Avalon's product registration page. Keep your model number, order number, and purchase date.
- Troubleshooting first: Every claim starts with troubleshooting alongside Avalon's support team. If a part fixes the issue, Avalon provides that part at no cost. A replacement unit is considered only after parts and troubleshooting have been tried.
- Installation and labor: Installation, maintenance, and repairs are the purchaser's responsibility. Plumber or third-party labor and extra installation materials are not covered.
- Not covered: Damage from accidents, misuse, improper installation or maintenance, relocation, unauthorized repairs, or unsanitary conditions. Units must be plugged directly into a grounded wall outlet. Using an extension cord or surge protector voids the warranty.
