A post inline carbon filter is the last filter in an RO system, sitting after the membrane and just before the tap. It polishes the water by removing any leftover taste or smell from the storage tank and lines, so the water you drink comes out clean and fresh. Water Treatment LLC supplies post carbon filters in Dubai and across the UAE. Send us your system details and we will confirm the right size and price.

Why Choose Us
A typical RO setup uses an in-line PP cartridge first, then an in-line GAC or in-line CTO filter, then the membrane, and finally the post carbon filter. We stock every stage, so you can replace a full set from one supplier and avoid mismatched sizes. If you aren’t sure which cartridge your purifier uses, send us a photo and we will match it.

Frequently Asked Questions
Why do I need a post carbon filter if my RO already cleans the water?
The RO membrane removes dissolved impurities, but the treated water then sits in the storage tank and passes through tubing before reaching your tap. It can pick up a stale taste or smell on the way. A post inline carbon filter polishes the water just before the faucet, so it tastes fresh. If your RO water tastes flat or has a slight odor, this filter is usually the first thing to check.
How do I know when my post carbon filter needs replacing?
Common signs are a returning taste or smell, a drop in flow from the tap, or a filter that has been in use for more than 6 to 12 months. The exact timing depends on your water quality and how much water you use. If you are unsure, send us your RO model and how long the current filter has been installed, and we will advise.
Can I replace the post carbon filter myself?
Usually yes. Most inline cartridges use quick-fit connections. Turn off the water supply, release the pressure by opening the tap, pull out the old cartridge, and fit the new one in the same flow direction (check the arrow on the filter). Run the water for a few minutes before drinking to flush out loose carbon dust. If your system is commercial or hard to access, our team can do it for you.
Does the post carbon filter go before or after the mineral cartridge?
In most domestic RO purifiers, the order is: sediment, carbon, RO membrane, post carbon, then the mineral stage. Since layouts differ between brands, tell us your purifier model or send a photo and we will confirm the correct position and cartridge.
How can I find the right post carbon filter for my purifier, and what does it cost?
Cartridges differ in size and connection type, so the easiest way is to send us the brand and model of your RO system or a photo of the old filter. We will match the cartridge and send the price. The cost depends on the size and quantity, and we can quote a full replacement set (pre-filters, membrane, post carbon) in one order.
