Whole-house sediment filtration
Sediment Guard 510 / 520
The Sediment Guard 510/520 is a simple, effective first line of defence: a large pleated cartridge on the main line that catches the grit — dirt, sand, silt, scale flakes and rust — before it reaches the rest of the house.
Pleated for capacity
The cartridge is a 5-micron pleated element. The pleats give it a large surface area, so it holds a lot of dirt before the pressure drop tells you it is time for a change. It uses no electricity and does not backwash — when the cartridge is loaded, you swap it (H-SGRC-510 for the SG510, H-SGRC-520 for the SG520).

Where it belongs
On municipal water it protects faucet aerators, valves, the water heater and any downstream filtration from particulate. On a well or after a water-main repair it is often essential. Milani usually installs it as the first stage ahead of any carbon, softening or RO equipment.
- Protects every downstream fixture and system
- No power or drain needed
- Simple cartridge swap on a pressure-drop cue
- Ideal first stage ahead of other treatment
How Milani installs and looks after it
Milani installs HALO equipment on the main line where water enters the home (or, for drinking-water and point-of-use units, under the kitchen sink), tests your water first so the system is matched to what you actually have, and sets it up with the correct bypass and shut-offs so future service is simple. Where a unit has replaceable cartridges or media, we tell you the schedule and supply the parts.
