How to clean your bidet: 4 steps to taking care of your Bidetmega

With the self cleaning functions and intuitive design, keeping your Bidetmega hygienic daily is easy and quick. As you enjoy using it over time, you’ll still need to ensure that you clean and maintain it regularly so it can continue to deliver the excellent performance you’ve become accustomed to. 

What you’ll need: 

  • Needle-nose pliers
  • Soft cloth or brush
  • A bucket or towel 
  • Water

1: Make that nozzle shine

Thanks to the innovative design of the Bidetmega, cleaning the nozzle is simple and sanitary. First turn the power off. Then, press the button to initiate the electrolyzed water spray, and gently scrub the nozzle with a soft brush or cloth. On the Bidetmega 150, this is the ‘rinse nozzle’ button, on the Bidetmega 200, this is the ‘extract nozzle’ button, and on the Bidetmega 400, this is the ‘cleanse nozzle’ button. Press the button again to return the nozzle to its original position.

2: Sparkle up the main body

Second, soak a sponge or soft cloth with neutral detergent and wipe down the body and button controls gently. Avoid alkaline or acidic products they may damage your Bidetmega.

3: Get the ducts clean and clear

The next step is to clean the nozzle duct, and then dry the duct once the main body is clean. To do this, simply lift the nozzle duct to detach it and remove the dry duct from the front by pulling on it gently. Make sure the duct doesn’t fall into the toilet during this process.

Cleanse the detached ducts thoroughly with water and a neutral detergent. Both the dry duct and nozzle duct must be fully dry before reattaching.

Clean the nozzle entrance with a soft brush or cloth, then reassemble the duct and flush the toilet after cleaning.

4: Clean out the mesh filter

The last step to cleaning your bidet is to clean the mesh filter. With the power cord still unplugged, lock the water supply valve (located under the sink) and detach the bidet hose. (There may be water left in the hose so prepare a towel or bucket to catch it)

Use needle-nose pliers to detach the mesh filter from the water intake section and cleanse the mesh with running water and a soft brush.

Then, return the filter back to the intake, reassemble the bidet hose, unlock the water supply valve and plug the power cord in.

1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.
→ Tested with Airmega Aim, 100, 150, 160, AP-1216L, AP-1512HH, AP-1512HHS, 200M, Icon, IconS, 230, 240, 250, 250 Art, 250S, 300, 300S, 400, 400S, ProX

299.97% of viruses, bacteria, fungi and pollen were verified to be removed from the air for Coway air purifiers which have Green True HEPA™ filter applied based on the Japan Food Research Laboratories(JFRL) testing according to JEM 1467 standard.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
