Any reviews on novita nap866?
Everything is about CADR, clean air delivery rate.
Roughly in theory CADR = air flow x filtration efficiency
Doesn't matter if the filter can remove 100% of the dust if the air flow sux.
Just look at Dyson purifier fan, they keep harping on their best filter but their airflow is poor since there is a huge bypass. That's why they don't publish CADR.
not everything
CADR is good, but if your filter cannot filter all, whats the point ? lol, its like getting a machine to suck air from your room and pump it out of your window (without any filter).
Please read proper what CADR stands for.

of cause i know what CADR means
Main thing is must be a workhorse. My Sharp KC-840 11 years old liao. And i'm just using those $4 a piece China HEPA.
Wow. How many detectors do you have? �Repost my earlier posting, this is for the generic Taobao HEPA filters that are cheap, those rmb 25 ones.
Of coz, my sensor is just sensitive to around 0.3 to 0.5 microns and not UFP (Ultrafine particles) capable. But this is also based on actual haze measurements here in Singapore.
You can see the detailed particle count numbers as well in the room.
All China H11 HEPA (measured to be 92%), except for the Mfresh M8088A which is true H12 HEPA (it's 99% thereabouts).
3 APs in the room. Mfresh M8088A actually is in lowest fan speed, coz i don't wanna load it too much. Most of the cleaning is done by the Samsung AX40 and Sharp KC-840 with China DIY HEPA, cut in size + sides stuffed with bubble wrap for sealing.
GPGT, proof that it works.
Few days ago Singapore haze.
Sudden transient peak @ 40k+ counts @ 0.5 microns
MBR (420 counts @ 0.5)
Mfresh M8088A H12, only 10 counts @ 0.5 microns lowest reading
Sharp KC-840 China DIY H11. Samsung AX40 is similar. 20 counts @ 0.5 microns lowest reading
is it just me or it's true that our nose can feel the difference when we breathe purified air?
There are some chinese APs with very high CADRs, 600, 700++ m3/hr. I posted them before on pages not more than 50 pages before this, during the Malaysian Pasir Gudang haze. Take a look there.

Thanks for the links again. Yeah. I looked at the larger Chinese units. Guess I am also wanting some local feedback from others who have bought these larger non-Xiaomi APs. Seems like either everyone is using older units from the past few years or getting Xiaomi 2s/Pros.

Yeah......if every year is like 2015, 2019, or even 2010 or brief very high-level spikes like 2013 (PSI 401 and that's based on 3hr PSI PM10, so the "index figure" for 1hr PM2.5 would even be significantly higher), i think i'd be willing to invest in a big ass one.
Anyway, my Mfresh M8088A is already 570 m3/hr CADR anyway. It was just rmb 988 then, and that time 4PX sent it over at 8kg weight, so that's 6 + (4 x 7) = SGD 34. It is something like a slightly fatter version of the Xiaomi Pro.
These electronics/small motor stuff still can be sent via official forwarder that time.
So if there is a need to put it into Turbo and blast, i still have something to do the shifting of air. Too loud though for anything more than 15 mins as it is 62dBA SPL.
After reducing the levels, i can switch to fan speed 2 or something, and together with the Sharp/Samsungs i can just maintain and coast along.
Also, my house is just 95 sqm. For those in penthouses or landed, with the living room area already at say 180 sqm and bedroom at 60 sqm, it might be a different story.
Too many, that's why i sold one to bro MIVEC325 after 2015.
Wa...still rem me...its still in my car...
