CrownGuard · Sovereign range

# Clean drinking water *for flats and villas.*

In coastal Oman the mains water is desalinated and treated, then it waits in a roof or ground tank and runs through the building's pipes. That is where taste, rust and sediment creep in. CrownGuard sits under the kitchen sink and filters them out, in units sized from a studio flat to a family villa. Our Oman partner fits and services it.

Every Twin handles sediment and taste. A Triple adds ultrafiltration, a barrier against bacteria, viruses and microplastics.

How CrownGuard works

## Three stages from *the tank to the tap.*

Stage 01

### Sediment filtration

Down to 5 microns

Stage one catches sand, silt and rust down to 5 microns, the grit that tanks and old pipes release into the water.

What's removed

-   Sand and silt
-   Rust from tanks and pipes
-   Dirt
-   Loose particles
-   Flakes of scale

**Why it matters:** The carbon after it lasts longer, and kettles and taps stay free of grit.

Stage 02

### Carbon block filtration

Up to 11,000 L capacity

Activated carbon removes chlorine, chemical traces and the organic compounds that cause musty tastes and smells.

What's removed

-   Chlorine and chloramines
-   Chemical traces
-   Pesticides and herbicides
-   Volatile organic compounds
-   Musty taste and smell

**Why it matters:** Water stored in a hot tank often tastes flat. Carbon gives it a clean, fresh taste again.

Stage 03

### Ultrafiltration membrane

0.01 micron · Triple systems

Triple systems add a hollow-fibre membrane with 0.01 micron pores. It holds back bacteria, viruses, cysts and microplastics, and lets calcium and magnesium through.

What's removed

-   Bacteria (99.99%)
-   Viruses (99.99%)
-   Cysts and parasites
-   Microplastics
-   Fine colloids

**Why it matters:** A physical barrier with no chemicals, and the finest stage CrownGuard offers. Unlike RO, it keeps the minerals.

Optional upgrade

### UV disinfection

Add a UV stage for one more barrier after the filters. It deals with 99.99% of microorganisms without chemicals.

#### 99.99% of microorganisms

UV light disrupts the DNA of bacteria and viruses. Nothing is added to the water.

#### LED lamps

LEDs rated for over 1,000 hours turn on by themselves whenever water flows.

#### Compact

62 × 68 × 91 mm, so it fits under the sink beside the filters.

#### Optional

Fitted on request, after the filters, if you want a disinfection step at the tap.

Your questions answered

## Home water filters in Oman, *answered.*

Q1Can I drink tap water in Muscat?

Nama's desalinated mains is treated to a drinking standard at source. The change happens in the building: tanks, pumps and pipes can add sediment, rust and a stale taste. CrownGuard filters at the tap, after all of that.

Q2We are on a well. Is CrownGuard enough?

Not on its own for the whole house. A well usually needs filtration, often a softener and UV on the main line. CrownGuard can then polish the drinking water at the kitchen sink.

Q3How often are filters changed?

Sediment and carbon every 6 months, and the UF membrane every 12. Each change takes a few minutes, or a maintenance plan from a fixed annual fee covers it.

Q4Will it save on bottled water?

For most families, yes, over time. There is nothing to order, store or carry, and no plastic to throw away.

Q5Does it work with my water pressure?

CrownGuard runs between 2 and 6 bar, which suits most flats and villas. If yours is outside that range, we tell you before fitting.

Q6Who installs CrownGuard in Oman?

Our Oman partner fits each system under the sink and can service it on a maintenance plan.

Local notes

## CrownGuard in Oman

Water in a home has usually spent time in a roof or ground tank, and on a farm or inland villa it may come from a well. Sand, rust and stale tastes are the common results.

CrownGuard fixes that under the sink or at the villa's inlet. Sediment and carbon stages handle grit and taste, and Triple models add ultrafiltration down to 0.01 micron.

### Common questions

Is CrownGuard enough for well water?

Filtration cleans it up, but for a private well or falaj supply we add the optional LED UV stage as the final step. It is compact, at 62 × 68 × 91 mm.

What is the Home Smart?

The villa version of CrownGuard, sold as a Twin or a Triple.

Will it soften hard water?

No. CrownGuard filters particles and taste. Hard inland water needs a Regal softener, and dissolved salts need reverse osmosis.

In Oman

## Specified, installed and looked after anywhere in Oman

Coastal mains water is mostly desalinated seawater. It is soft, but it picks things up in pipes and tanks. Inland wells can be very hard: one 2024 study of Al Dhahirah groundwater found an average hardness of 659 mg/l.

Say which governorate you are in, whether the water comes from the Nama network, a tank or a well, and what you need it for. We design the system, price it in rials and arrange the fit.
