Easy Steps For Cleaning
It’s essential to clean the filters for numerous reasons. The most obvious one is the fact that there’s no point of having a purifier when the filter cannot trap the particles due to the fact that you haven’t cleaned it properly. In addition to this, the purifier will work harder in order to try to remove every contaminant in the air. The more strain is put on the system; the less time it will work efficiently. Also, it will consume a lot of energy. This means that you will see spikes in your electricity bill payment. You should follow the steps below accordingly.
In order to clean them properly, you will need to have patience and willingness. The good thing about it is the fact that you don’t have to do a lot of manual work. The dust can be easily removed if you have the right equipment and tools available. The main idea is that you remove it from the purifier in order to make your job easier. In order to clean it properly, you will have to:
- Step 1: Turn off the purifier and unplug it
- Step 2: With a damp cloth, clean the exterior of the purifier without adding too much water
- Step 3: Use a small soft brush to clean the air vent
- Step 4: Use a dry cloth to remove any dirt or dust when cleaning the internal part of the purifier
- Step 5: Remove any dirt you see with a dry cloth and assemble the purifier together
These filters are more difficult to be clean due to the fact that they are the first filters exposed to large dust particles. Therefore, we recommend that you wear a mask when removing the dirt because you want to avoid inhaling the particles as much as you can. There’s no point protecting yourself if, in the end, you inhale the particles when cleaning it. You should:
- Step 1: Turn off the purifier and unplug it
- Step 2: Check the condition of the pre-filter, you should do it every 3 weeks
- Step 3: If dust is visible, you should remove it from the purifier
- Step 4: Wash it using warm and soapy water. Do this by hand and avoid using too much water
- Step 5: If the pre-filter is damaged or over-used, you will need to purchase a new one. If it’s in the right condition, put it back in the exact position that you’ve removed it from
In order to maintain high-efficiency, you will need to wash it consistently and keep up the maintenance. The good thing about it is the fact that all of the models mentioned will come with an indicator light. This will let you know when it’s time to wash the filter. In order to clean it, you will have to:
- Step 1: Turn off the purifier and unplug it
- Step 2: Check the condition of the permanent filter, you should do it every 3 weeks
- Step 3: If dust is visible, you should remove it from the purifier and wash it using warm and soapy water. Do this by hand and avoid using too much water
- Step 4: If the filter cannot be removed from the purifier, you need to run the brush attachment along both sides. The key idea is the fact that you shouldn’t use detergents or chemicals.
- Step 5: Even though your filter may seem over-used, you don’t have to worry. It’s usual to see discoloration on a filter that has functioned continuously for numerous years.
