How It Works – 4-Stage Purification

How It Works

Mains water pressure forces contaminated water against a semi-permeable membrane. Pure water molecules pass through easily while dissolved pollutants, salts, and contaminants larger than the membrane’s ultra-fine pores (0.0005 micron) are rejected and flushed down the drain.

 

1. Carbon Pre-Filter (5 micron) Reduces chlorine, bad taste, odor, and organic compounds.

2. RO (Reverse Osmosis) Membrane The core of the system. Reduces dissolved solids, heavy metals, and a broad spectrum of contaminants.

3. Carbon Post Filter (5 micron) Removes fine (Final water polishing filter) particulate matter.

4. Alkalizing Filter pH Booster Adds beneficial minerals back and raises the pH for healthier, better-tasting water.

Frequently Asked Questions

How often do the filters need to be changed?

Most homes change the complete filter set once a year. The smart faucet will light up when it’s time.

​

Does this system waste a lot of water?

The Halo Ultra Plus is designed for efficient 1:1 production under normal conditions — significantly better than many older RO systems.

​

Will it fit under my sink?

Yes. The system is compact and designed for standard under-sink installation. Our technicians confirm fit during the free assessment.

​

Will any alterations be needed for installation?

Yes. A small ½″ hole must be drilled into the countertop or sink, approximately 7″ to the right of your existing faucet, to install the RO faucet. This is required for proper installation.

​

Is professional installation required?

Yes. Proper installation (including pressure regulation and leak protection) is important for performance and warranty. We handle everything.

​

Can I combine this with a whole-house system?

Absolutely. Many customers install the Halo Ultra Plus RO together with a Halo 5 whole-house system for complete protection.

​

Do you offer maintenance?

Yes. We can schedule annual filter changes and system checks so you never have to worry about it.
