The replacement of Maya V2's HEPA filter is pretty simple and everyone can manage it in no time. It only takes a few minutes.
Firstly, you have to take out the dustbin of Maya V2, open its cover, and empty it. Then, after you have poured out the rubbish, you can proceed by opening the cover of the HEPA filter on the dustbin. Now, take out the primary filter and the HEPA filter - you can lightly pat the dust off the HEPA filter or directly replace it with a new one, in case if it's too dirty or has been used for a long period of time. As for the primary filter, you can just wash it manually in the sink and leave it to dry.
Keep in mind that it's prohibited to wash the dustbin. Please use a mop to keep it clean.
Once you have patted the dust off the HEPA or replaced it with a new one, you can re-assemble the primary filter, as well as the HEPA, back in the dustbin and mount it on your Maya V2.
