Whole house filtration
Clean, safe water from every tap
The Aqua Best 3 Stage Filtration System is a whole house water filter designed to help every drop of water in your home be clean, safe and refreshing. Advanced multi-stage filtration and robust construction are built to deliver consistently good water quality from every tap.
It filters water as it enters the property, so showers, kitchens, laundry and appliances all receive filtered water. This system is a filtration unit, not an RO purifier, so it is not designed to remove dissolved salts. Final water quality depends on the incoming water and regular cartridge changes.
Why choose the 3 Stage System
- Three cartridge stages in one line
- Thicker walls for long-lasting performance
- Rated for high-pressure operation
- Flexible 1" or 1.5" inlet and outlet
- Bracket and wrench included
How it works
The 3-stage filtration process
Water passes from coarse to fine, so each cartridge protects the next.
PP Sediment Filter, 5 Micron
20" x 4.5" cartridge. Efficiently captures coarse particles and sediments at the start of the line.
CTO Filter
20" x 4.5" cartridge. Helps reduce chlorine, odour and taste issues for improved water quality.
PP Sediment Filter, 1 Micron
20" x 4.5" cartridge. Removes fine particulates for enhanced purity.
Installation and durability
Built to last, easy to fit
Housings are built with thicker walls for long-lasting performance. They carry a maximum working pressure of 125 PSI and a burst pressure of 250 PSI, for reliable operation under high-pressure conditions.
Inlet and outlet are available in 1" or 1.5" sizes, with a 3/4" port for secure, easy connection. A bracket and wrench come with the system for a hassle-free installation.

3 stage filter questions
What is a 3 stage whole house water filter?
It is a three-cartridge filter fitted on your main water line. It uses a 5 micron PP sediment filter, a CTO carbon filter and a 1 micron PP sediment filter, so filtered water reaches every tap.
Is this the same as an RO purifier?
No. This is a filtration system for sediment, chlorine, odour and taste. It is not designed to remove dissolved salts. For drinking water treated with RO, we can pair it with a domestic RO purifier.
What size are the cartridges?
All three cartridges are 20" x 4.5".
What pipe sizes does it fit?
Inlet and outlet are available in 1" or 1.5" sizes, with a 3/4" port size. Tell us your pipe size and we will confirm the right fit.
What is the pressure rating?
Maximum working pressure is 125 PSI and burst pressure is 250 PSI.
What comes in the box?
The system comes with a mounting bracket and a wrench for installation.
How often should cartridges be changed?
It depends on water quality and usage. Many homes change sediment and carbon cartridges about every 3 to 6 months. We will help you set a schedule for your property.
Do you install in Dubai?
Yes. We provide installation and maintenance for water filtration systems in Dubai and across the UAE.
