Always clean the filter outside, because you just used a tiny vacuum that has no HEPA filter to scatter those already filtered particles all over your apartment!
best you can do to clean the outside filter is wipe it sometimes, ive heard its not very good for hepa (might damage the hepa) to vacuum it etc. i guess, maybe, with a very low suction its not that harmful, but still makes sense to simply buy a new one for better resluts
If your HEPA filter is not specifically labelled as washable or “permanent,” then the answer is no. You can rinse the filter in water, tap excess dust off of it or remove some dust with a vacuum, but this can definitely damage the mesh of fibers that allows the filter to remove particles from the air. Even if the filter looks undamaged, some of the fibers will be broken or stretched out. You will end up with a somewhat clean looking filter that does not do the job of filtering properly.
exactly. Just because it looks clean, doesn’t mean it is clean and indeed, hepa filters can be easily damaged by “cleaning” actions. I don’t get it either. People are concerned enough to get an air purifier but are then too stingy to buy a clean filter replacement…
@@thomas_xsg why waste a filter by making it filter super huge dust particles. I installed a cheap non woven open filter in the filter housing just to collect dust and make the hepa only filter small particles. The mesh is way too large the filter wil clog and reduce its effectiveness. some more expensive air filtration systems have many pre-filters if yours does not you simply need to add your own. try to maintain airflow as much as possible. these non woven filters are cheap at about 1 euro per filter. the HEPA filter costs upto 30-100 dollars per change.
@@MrJob91 I get your point and I think that cleaning off the outside dust by hand is a good idea so it will not clog up the filter. But vacuuming it out with a regular non HEPA vacuum will suck all the small particles (pm 2.5) out of the filter and throw it back in the air. So that’s totally useless.
@@z3ro7o yes... the airpurifier count the days since you use the air purifier till 60 days or less or more then it tells you to change the filter... even if its clean the airpurifier programed on 60 days or less or more show him change filter... just vacuum the filter and wash the first filter and thats it... dont let them fool you... they make this thing just to get more money from you... i have 3 air purifier and everytime they show change filter i take the filters out and clean all of them then return them back and i press reset and wala
there is a nfc tag at the bottom so the device knows when it was first used... as i know it will only work for max 1 year when it is first activated even if you clean it
The more dust on the filter the better it filters and the dust magnifies each other particles (or/and just fills the bigger holes) that's why the dusted filter is filled quicker with more dust than the new one (having therefore better filtering properties) though the dusted filter can loose some of its covered dust. Though car filtrers are sprayed with some type of oil for dust stick.
Man, you need to vacuume your place or use elecrostatic cotton for your filters and vacuume filters too. I live in heavy smog area, but this is not smog, this is dust from not vacuming your place. You don't wash hepa, it will destoy and vacumming can add up about 10% of lifespan. But you can partly regenerate carbon if it's used up quicker than hepa (new appartments after painting, chemical factory ner by). Carbon can be regenerate via hi heat or oxidation, so putting filters during summer to direct sunlight on roof or other metal surface (but isolete direct touch with plastic), or using ozone generating strong UVC lamp, or spraying hydrogen peroxide or opening filter and putting carbon into HCL acid bath and 20min in microwave could do the trick (don't eat food from that microvawe or inhale shit during processing). Sometimes enzymes could do the work too, like vapoures from non-fragrance washing mashine detergent, or something like oxi-action detergent but without fragrance/perfume(which would fill up carbon). Xiaomi purifiers got a lot of space inside to put extra DIY stuff like ionizer, UVC lamp + photocatalyst filter from dikin inside cylinder, electrostatic cotton or carbon wrap around cylinder and extra carbon on side walls. You know when carbon is used up when it will give up smell. It gives up more when it's dry and takes more when it's more humidity. Generally it dry's air which is not good for mucosal immunity so use some kind of humidifier to keep around 50% humidity in air.
Its not about whats visible. its about invisible particles trapped in your hepa filter which you cant see. That's why it should be changed every 6m -1y.
@@thomas_xsg My air quality ranges from 1-4 on my xiaomi air purifier... and after 150 days, the filter is "done" - NFC keeps me from resetting it, even the pre filter was only very mildly dusty on a few spots, most of the surface was dustfree... and i still have to change it because the nfc chip is reset proof...
@@jan14788 True, I have the same and I definitely think you can use the filter for much longer if the air quality is generally OK. I just don't think it makes sense to clean a filter when it's clearly very dirty. In those cases, just replace it. Otherwise it kinda defeats the purpose
Where’s the other two layers? What you vacuumed looks to be pre-filter which can be reused. The hepa filter on other brands also includes a carbon filter that further traps smaller particles while a more fibrous hepa filter traps microbes and other allergens. Basically these two are the ones that must be replaced. It seems like you only have the pre-filter.
