Not really. Just do a simple google translate, from the keywords, you can infer that the product claims are with regards to absorbing formaldehyde and odours.

Foxwoods activated carbon charcoal bag of activated carbon to remove formaldehyde new home decoration in addition to formaldehyde odor absorbing carbon package home

So in that sense, yes, since it is activated carbon, it partially acts like air purifier, but only like the activated carbon layer (if your filter has one), but it does not act like the mechanical filtration of particulates like the HEPA filter does (will not remove particulates in the air).

Activated carbon is made to get smells and gases like VOCs. It is not designed to get particulate in general. In fact, activated carbon is made to be as porous as possible to get as much air into contact with the carbon.

1. After turning off the power for Baygon liquid repeller, do you unscrew the liquid bottle then screw on the bottle cap?

2. If I only turn off the power and the liquid bottle is still unscrewed, attached to the white plastic Baygon plug head, is it still giving out vapours?

I turn off the the power only, I then switch on the air con and windows/door is closed, not sure if I am breathing in any vapours

blow out from the purifier? what do u think the hepa filter is for?

 

[kandinsky]

Air purifer say you need to change the pre-filter every 3 months.

This means during the 3 months alot of dust is accumulated inside the purifer so when u on it everyday, you are actually breathing in all the dust that will blow out from the purifer?

Thus, using a purifer is actually worst?

Not following your train of thought. Logic fail?

If the filter is working as intended, why will any of the dust pass through? It will be trapped in the filter. If you put it there indefinitely, in theory the filter will get more and more clogged until no air passes through at all.

If your AP is blowing out dust, maybe you took out the old filter and forgot to replace a new one

Hello guys, I'm planning to get a air purifier for my office use, wondering if there are any affordable recommendations here that can be placed on the table or something?

But I understand that air purifiers are meant to purify the whole room, but I dont have a room to myself as we are just in office cubicles, so not sure if buying a personal purifier will have any use? Maybe a small rated one will do?

Is your office in a good "A-grade" commercial building? If so, no worries.....the air is already filtered quite ok. But if old buildings with old AHUs/HVACs, then maybe got sick building syndrome (nowadays also somewhat rare liao)

Not sure if counted as A-grade ley haha. But I know i'm prone to getting infected by flus and coughs quite easily so wanted to see if there's anything to help.

ur office a lot of paper and cupboard boxes?

 

[tmfwy]

Any recommendations for an air purifier for master bedroom use?

basically, to mitigate the amount of dust in the room...

Can be either the continuous usage during sleep
or on for 1 hour before sleep type to do its work...etc

Secondary concern is the cost of the replacement filters or rather, the availability of OEM replacement filters..

Can anyone tell me if the sensors in xiaomi air purifier 2 is accurate?

In the app the humidity is at around 70%. Is that a good thing or bad thing? Reason I'm asking is my walls have these white powdery stuff appearing every time Nippon painters come down to paint can't solve the problem, thier technical team took a sample to analyze and will get back to me soon.
