Filtration for Saudi roof-tank water.
In Riyadh, Jeddah and other cities, water often waits in a roof tank before it reaches the kitchen. CrownGuard sits under the sink and filters out the sediment and taste it picks up there, in sizes for flats and villas. Our team in Saudi Arabia installs and services it.
Three sizes, flat to villa.
Each system fits under the kitchen sink and is sized to the household. Choose a Twin, or a Triple with ultrafiltration.
Apartment
A compact system for studios and smaller flats, built to leave room in the cupboard. Twin or Triple.
- Compact under-sink unit
- Filters at 300 L/h
- Twin or Triple build
- Comes with a fitting kit
Home Triple
Three-stage filtration with an ultrafiltration membrane, for family flats and villas.
- Three stages including UF
- Filters at 300 L/h
- For households of 2 to 6
- Comes with a fitting kit
Home Smart
An enclosed model with an LCD panel that counts filter life and alerts you when it is time to change.
- LCD panel and alerts
- Automatic filter reminders
- Flood protection
- Fully enclosed unit
Every model, side by side.
Twins deal with sediment and taste. Triples add the ultrafiltration stage that stops bacteria, viruses and microplastics.

How CrownGuard cleans roof-tank water.
Sediment filtration
Down to 5 micronsSediment filtration catches particles down to 5 microns, including the silt and rust that settle in roof tanks over the summer.
- Silt and sand
- Rust flakes
- Soil particles
- Tank sediment
- Loose scale
Why it matters: Clearing grit first protects the carbon stage and the appliances after it.
Carbon block filtration
Up to 11,000 L capacityActivated carbon removes chlorine, chemical traces and the compounds that make warm, stored water taste flat or smell.
- Chlorine and chloramines
- Chemical traces
- Pesticides and herbicides
- Volatile organic compounds
- Odd tastes and smells
Why it matters: It gives tank water a clean taste again, which matters for tea, coffee and cooking.
Ultrafiltration membrane
0.01 micron · Triple systemsTriple systems add a 0.01 micron hollow-fibre membrane. It blocks bacteria, viruses, cysts and microplastics but lets calcium and magnesium through.
- Bacteria (99.99%)
- Viruses (99.99%)
- Cysts and parasites
- Microplastics
- Colloids
Why it matters: Water warms up in a roof tank. The membrane is a chemical-free barrier after it, and unlike reverse osmosis it keeps the minerals.
UV disinfection
Add a chemical-free UV stage that deals with 99.99% of microorganisms after filtration.
99.99% of microbes
UV light disables bacteria and viruses at the DNA level, with no chemicals.
Long-life LEDs
LED lamps rated for over 1,000 hours turn on automatically when water runs.
Fits under the sink
Measuring 62 × 68 × 91 mm, it sits beside the filters.
For roof-tank homes
A sensible extra where water is stored on the roof through the summer.

CrownGuard in Saudi Arabia
In Riyadh and Jeddah, water often sits in a roof tank through the summer heat before it reaches the kitchen. Warm, still water is where sediment settles and taste fades.
CrownGuard treats it on the way in: sediment out at 5 microns, chlorine and taste out through carbon, and an ultrafiltration stage down to 0.01 microns on the Triple.
Common questions
Will it help with roof-tank water?
Yes. That is what it is designed for: sediment, taste and odour picked up between the mains and your tap.
How many litres does a carbon block last?
Up to 11,000 litres.
Is it enough for a villa?
Yes. It delivers 300 litres an hour, and the Home Triple and Home Smart models are built for villas.
Supplied, installed and serviced in Saudi Arabia
Saudi supply is a mix of desalinated water and groundwater. Where groundwater is blended in, as in Riyadh, the water can be hard enough to scale heaters and machines, so we check your supply before choosing a system.
Tell us your city, whether the site is on mains or tanker water, and what the system is for. We specify it, quote in riyals and install it.
