Ways to Clean Water Purifier at Home

Why should you bother asking for outside help when you can get it done in the comfort of your house? Yes, it might require some elbow grease, but it can go a long way in keeping your water purifier clean.

As there are several ways through which you can clean a water purifier. We have carefully segregated the processes for better understanding.

Clean the Reverse Osmosis Filter

Reverse Osmosis Filter

For general knowledge, Reverse Osmosis (RO) is a water treatment process through which the contaminants are removed from the water. Pressure is used to force water molecules through a semipermeable membrane. Once the process is completed, all the toxins and contaminants are filtered out.

Even though it has a scientific ring to it, it is rather plausible to clean the RO filter at home. To complete this process quickly, let us understand the two different levels associated with this filter.

The first is the reverse osmosis membrane filter that is responsible for the efficiency of the water filter. The second level consists of pre-filters that are made with activated carbon.

It is advisable to change the reserved osmosis filter every 24 months. The pre-filters must be changed every 12 months.

Now, let us get started with the cleaning process.

Step 1:

Shut off the water supply to the filtration system. Wash your hands thoroughly and wear medical gloves. Rubber gloves will also do the trick. Drain whatever water is left in the filtration system and tank. Shut down the faucet or the valve attached to the system.


Step 2:

Open the gasket and remove the reverse osmosis membrane and the pre-filters from the water purifier. If it is encased, use a wrench to remove it.


Step 3:

Use chemical cleaners to clean the filtration system. If you do not wish to invest in outside products, unscented bleach can also come in handy.


Step 4:

Prepare a solution with water and a chemical package. As different chemicals react differently, you can scan the directions for the proportions on the package.

Soak the membrane in the prepared solution for an hour. Remove it and clean it under running water.


Step 5:

Place the membrane and turn the water supply back on. Let the water run through it for half an hour to flush it out.


Clean Sediment Filters

Clean Sediment Filters

Sediment filters purify the water by capturing dirt and sand with its net. Such filters can be extremely beneficial, especially if your city supply contains a high amount of impurities.

Ideally, these filters should be cleaned once a year.

Step 1:

Remove the filter housing from the water purifier system along with the cartridge. Rinse the housing with water after placing the O-ring aside.


Step 2:

Place the filter under clean running water. Try to run your fingers across it under running water to remove any visible dirt traces or particles.


Step 3:

Prepare a solution of oxalic acid and water in a 2:1 proportion. Once the solution is ready, soak the housing with the cartridge for 30 minutes. Avoid scrubbing while it is being soaked.


Step 4:

Rinse the filters under clean running water. Ensure that there are no traces left behind.


Step 5:

Let the filter dry before you replace it in the filtration system.


Clean the Activated Carbon/Charcoal Filters

Activated Carbon

When it comes to water filters, activated carbon/charcoal filters are useful in removing chlorine. Besides that, they also help remove other particles like volatile organic compounds, sediment, odour, etc.

It is not difficult to clean activated carbon/charcoal filters. However, you have to be extra careful while doing so.

Step 1:

Wear a pair of gloves as well as a mask and goggles.


Step 2:

Prepare a solution with water and muriatic acid. Slowly add the acid to the water and stir it consistently.


Step 3:

Remove the filter from the purifying system and rinse it under running water. Ensure that there is no debris left behind.


Step 4:

Place the filter in the prepared solution, and let it soak for five-six days. Yes, this process will take time, but it is necessary to remove all the contaminants.


Step 5:

After the set period, remove the filter and soak it in clean water for 15-30 minutes. Rinse it with clean water.

Once it has dried, you can place it in the cartridge. Turn on the water supply and let the water run through it for 15 minutes before you start using it.


Clean the Quartz Sleeve in UV Lamps

As the name suggests, the UV water purification system utilises a UV light source to produce radiation. This is used to purify water and get rid of any contaminants. As this consumes very little energy, it is preferred by several people.

A UV water purifier is made up of two components: a UV lamp and a quartz sleeve.

You cannot clean the UV lamp as it needs to be replaced. It is advisable to replace it once a year. But when it comes to the quartz sleeve, you can clean it at home.

Step 1:

Turn off the water supply.


Step 2:

You would notice a safety cap at the top of the purifier. Remove it by squeezing the tabs. Do not touch the lamp plug wires during this process.


Step 3:

Remove the lamp plug and quartz sleeve with the sleeve bolt. Hold the sleeve bolt and unscrew the UV lamp. Remove the O-rings from the quartz sleeve.


Step 4:

Take some vinegar and dip a few tissue papers. Once they are soaked, cover the sleeve with those tissue papers. Let it aside for 20-30 minutes.


Step 5:

Rinse it under clean running water. Once it is dry, place it in its original position.

Even though you can clean it at home, we recommend replacing the quartz sleeve once every two years.
