Check the model and thread color first. For Olympus countertop and under-sink units, the filter name and thread color at the base of the cartridge used will tell you which part to order.
Standard cartridges for basic filtration have a green thread. Those for limescale reduction have a blue thread, and those for nitrates have a red thread. The GIGA series uses other colors: brown for basic filtration, yellow for limescale, and white for nitrates.
The mini filter, bathroom filter, and thermos bottle use cartridges dedicated to each device.
What to check before ordering
You can find the model of the appliance in the purchase documents; also check the markings on the cartridge. If you need to open the filter installed under the sink to see the color of the thread, first turn off the water supply and follow the instructions for your model.
Also confirm the filter model. The basic cartridge standard has a capacity of up to 8,000 liters, and the JIG, up to 14,000 liters, respecting the time limit in both cases.

When both a duration and a capacity in liters are indicated, the cartridge is changed at the first limit reached. Resins have approximate regeneration intervals. The frequency depends on the composition of the water.
The Olympus antimicrobial filter includes the filter cartridge. The parts for subsequent replacements are selected according to the model of the device and changed at the intervals specified in the instructions.
How long can you use the cartridge?
For the standard basic cartridge, the stated limit is up to 12 months or 8,000 liters. For the GIGA, the capacity increases to 14,000 liters, and the time limit remains one year.
The Olympus instructions recommend replacing the cartridge no later than 10-12 months after commissioning, even if you have not reached the consumption in liters. Note the installation date after each change. In networks with many particles of sludge, rust or soil, the cartridge may require more frequent cleaning.
Cleaning the ceramic cartridge This should be done every 3-4 months or when the flow rate noticeably decreases. Rub the outer surface of the ceramic filter under cold water with the abrasive side of the dish sponge, as shown in the instructions. NOT use detergent. Resin cartridges are maintained by regeneration, WITHOUT cleaning.
How to replace the ceramic cartridge
For countertop and under-sink antimicrobial filters, replacement includes mounting the part and preparing it for use:
- Turn off the water supply (under-sink filter only) and unscrew the stainless steel filter cap, following the appliance's instructions.
- Remove the old cartridge very carefully..
- Remove the foil from the new cartridge and screw it clockwise, without tightening it excessively.
- Screw the metal cap firmly back to the place.
- Let the water run for 10 minutes., then do not use the filter for 24 hours. When resuming use, let the water run for another 4-5 minutes according to the instructions. During the first rinse, the water may turn black due to the activated carbon.
Respect the position of each cartridge. On standard double and triple models, the cartridge with the green thread is mounted in position 1, and those with the blue or red thread, on the other bases, in the order allowed by the device instructions.
For installation and maintenance, consult instructions for use. The guide about under sink water filter It also explains the complete installation of the device.
Regeneration of cartridges for limescale and nitrates
Blue, red, yellow and white thread cartridges contain resin, which is regenerated at the recommended intervals for the cartridge type and water composition. You use a solution of water and salt.
For the limescale reduction cartridge, the manufacturer indicates approximately 350 liters between regenerations, at a water hardness of up to 20-22 German degrees (°dH). For the nitrate cartridge, it indicates approximately 150 liters when the concentration is up to 55 mg/L and shorter intervals at higher concentrations.
The procedure described by Olympus is as follows:
- Remove the cartridge from the appliance after turning off the water supply (if the filter is mounted under the sink).
- Prepare a narrow, tall container with a capacity of 1-2 liters. Add water and dissolve 3-4 tablespoons of table salt, preferably coarse.
- Completely submerge the cartridge in the solution.
- After 30-45 minutes, remove it, rinse the outside with tap water, and reinstall it.
- Let the water flow through the reassembled filter for about a minute.
Regeneration is part of maintenance. Replace the resin cartridge every 10-12 months. For concentrations and analysis interpretation, see the article about nitrates and nitrites in tap water.
Reverse osmosis cartridges and 10 inch variants
Reverse osmosis filter Olympus has four stages, with different spare parts and replacement intervals:
| Stage | Replacement cartridge | Replacement | Price |
|---|---|---|---|
| 1 | PP sediment filter | 3-6 months | 20 lei (4 €) |
| 2 | Pressed activated carbon 10″ CTO | 9-12 months | 125 lei (25 €) |
| 3 | Reverse osmosis membrane | 12-18 months | 235 lei (47 €) |
| 4 | Carbon filter T33 | 9-12 months | 70 lei (14 €) |
Intervals depend on water and consumption. Check the filtration stage before ordering. The name of the part you are replacing must correspond to the stage in which you will install it.

The latter is intended to retain chlorine, odors and particles, with a declared duration of one year or 10,000 liters, depending on the limit reached first.
Cartridges for mini filter, shower and thermos
Mini faucet filter uses an 85 lei (17 €) cartridge, which is replaced every 6 months or 2,000 liters, depending on the limit reached first.
Bathroom filter cartridge It costs 150 lei (30 €) and is replaced every year or 30,000 liters, depending on which limit is reached first. The position of the device and its installation are explained in the guide. shower filter.
