Shower filter maintenance

The filter cartridges are designed to last 10,000 gallons or about 6 months of normal use. They require replacement once in 4-6 months (~ 10 000 gallons) depending on water quality and frequency of use. The water pressure decreases when it is time to replace the filter cartridge.

Disconnect the filter body from the shower head. Turn the bottom of the shower filter counterclockwise until it separates from the top. Place the new filter cartridge with the mesh up to the water flow so the water enters through the mesh and exits through the holes.

Shower head maintenance

For better efficiency replace the vitamin c+e cartridge in the shower head every 8-10 months.

Disconnect the shower head from the shower filter. Then turn the bottom part of the shower head counterclockwise and remove the old vitamin cartridge. You might need to use rubber gloves for better grip.

For the best shower experience, clean the spray plate under the tap on both sides. You may find it very effective to soak the spray plate in hot water combined with baking citric acid and leave it for half an hour then clean with a towel and install into the shower head again.


The problem may be caused by large O-rings slipping off inside the filter housing. To resolve the issue:

1. Disconnect the filter from the shower head, turn the bottom of the shower filter counterclockwise until it separates from the top. 

2. Check if rubber o-rings are in place. If one is damaged or disformed you can replace it with a spare one from the product box. 

3. Connect both halves of the filter again. Make sure the filter cartridge is placed with the mesh up to the water flow.

The movement of the ball joint can be regulated by the nut that is located on the joint itself. 

Try loosening the nut with a wrench or rubber gloves for a better grip. Loosen it so that the ball can rotate, but not too much so that there is no water leakage.

Make sure that the filter cartridge does not require replacement. The cartridge should be changed every 4-6 months. 

There are two main reasons that may cause this problem: 

Over time, the filter cartridge can become clogged with sediment present in the plumbing. To unblock the filter cartridge detach the shower head from the filter housing, unscrew the filter body and take out the filter cartridge. 

Place the cartridge, holes up, under the faucet and flush it for about 3-5 minutes. 

After that, install it into the filter housing with the mesh facing the water flow.

Another reason may be a flow restrictor installed into the ball joint part of the shower head. The sediment may block the openings in the flow reducer. Rinse any stuck particles under the faucet. Check the mesh gasket that locates on top of the flow restrictor as well. 

This problem can be caused by an excessive amount of calcium and magnesium minerals in the water. 

It can be solved by soaking the spray plate in hot water with citric acid added. Leave it for half an hour, then wipe it with a towel and reinstall in the shower head.

Alternatively, you can replace the clogged spray plate with a spare one from the product box.

A TDS meter can identify dangerous impurities, but only if they are electrolytes. But impurities, which are non-electrolytes, will go unnoticed. In other words, using a TDS meter alone, you will not determine the purity and safety of tap water, since:

- not all electrolyte substances are dangerous;

- not all hazardous substances are electrolytes, which means they remain invisible to the TDS meter.

The best way to test the effectiveness of a shower filter is to use a chlorine colorimeter or chlorine test strips.
