Has anyone tried Xiaomi Air Purifiers and Air Purifiers in general - Any good?

My feedback on the Philips Air Purifier - AC0819/10 (R2499.99 via eBucks fulfilled by Hirsch's) is that it either doesn't work or it doesn't filter out VOCs. We got an old table painted with some sort of grey wood stain, it stunk to high heaven, my sinuses went ballistic from the time this thing arrived, info on what was done to this table was handled by my SO hence it wasn't really at the forefront of my mind that this thing was slowly poisoning us, we have no outdoor space (in a first floor apartment) hence it had to stay indoors. I setup the air purifier and placed it on the table as per my previous post #36 above, The light started off red, then progressed to purple (fair) and maybe by the next day it was blue (good). The table continued to stink for a few days and my sinuses did not let up, bad enough to have a mild headache all that time. The last few days I had the purifier next to my bedside, but barely any sinus (and headache) relief until a couple days ago when the table started to stink less.

In any event, In think I want to try the Xiaomi Smart Air Purifier 4 Compact for R1899 (I see it could be cheaper according to ServalTracker). One of the purifiers can go in my WFH / gaming office, and the other one we can keep in the bedroom or living area.

@airborne what did you end up buying?

You can’t expect the wood the magically stop seeping odour/chemicals.

You are treating the symptom and not the cause and no other brand will fix that either.

Seal or varnish the table, or get rid of it but air purifier won’t fix that.

Probably more than a year. Its been running almost every day the last 6 months.

I have remov thick dust from the sides from time to time.

I will probably replace it in july when the harvest start blooming

It's mostlu effective running at a higher speed all the time.

I have actually been looking at building my own filter but I dont know where to buy the hepa filters in South Africa.

The home build ones works better aparantly because it's all about airflow.

Have you managed to figure out how to build your own filter?
 
Wondering myself if there's a filter manufacturing machine you can buy...

Yeah, but I still need to build it.
I figured 90% of my sinus issues are because of drinking milk, so my need for it has decreased.
I was mildly sick this weekend due to the pollen, so during the peak pollen season, I still need it.
Usually, with pills and all, I would be in bed for a couple of days, but now it's much better.

Anyway,
My idea is more or less the same as the youtube guys are showing.


My idea is to get 4 200mm pc silent pc fans. Noctua or something similar.
Then I will build brackets to put 4 of these or longer filters to together.
If I can get one big, silent fan, then I will use that.

Here are some filters which I found.
I need to go through the specs again to make sure these filter out pollen but I think they do.

I see these are now available in South Africa

Beurer LR 200/210 replacement set with HEPA filter class H 13​


I still need to get an easy way to supply the 12v to each fan by I have a old pc psu which I will probably use if I can't do something more elegant.
One big fan won't need this, so would probably be easier and better than 4 small fans.

I am getting a 3D printer and learning Autodesk Fusion which is very cool so I will build mine with 3D printed parts.
That won't happen this winter because I have other projects lined up first.
 

FYI

Air Fresheners and Air Purifiers​

Air fresheners can affect air purifiers, particularly those with activated carbon filters. Air fresheners often emit volatile organic compounds (VOCs) and other chemicals that can be absorbed by the carbon filter in an air purifier. This can cause the filter to become saturated more quickly, reducing its effectiveness and requiring more frequent replacements. Additionally, using scented products like air fresheners with an air purifier can be counterproductive, as the carbon filter may absorb the scent, leading to the filter producing other smells over time.
While air purifiers are designed to remove contaminants and improve air quality, the use of air fresheners can introduce new pollutants into the air, which the purifier may not fully eliminate. Therefore, it is generally recommended to use air purifiers without air fresheners to maintain optimal air quality.
If you do choose to use air fresheners, it is important to ensure that they are natural and do not contain harmful chemicals, as these can still impact the performance of the air purifier. In summary, while air fresheners do not directly damage air purifiers, they can reduce their effectiveness and increase maintenance needs
 
I've ordered this off TEMU, hopefully they work.

Is there some sort of meter you can buy to test out the air quality for your home?
