Industry Standard Size 10" × 2.5" Inline Post-Filter Cartridge

T33-RO inline water filter is made with premium coconut shell-based activated carbon and is original equipment on our USRO line of Reverse Osmosis Systems.

T33-RO is an Reverse Osmosis post filter. It clips on to the membrane housing and filters the water after the bladder tank, acting as a polishing filter just before the water is dispensed.

T33-RO is the same filter as our standard T33, but with a custom label for our Reverse Osmosis Systems.

Other applications include: appliances, water coolers, coffee makers, and other low flow applications.
