how often do you guys replace your xiaomi filter if on 24/7 on low setting?

need to ask something

the xiaomi app pm2.5 reading

is that ug/m3 or AQI units?

Hi there,

Was looking around the forum for AP's,
I'm thinking to get a Xiao mi 2 units for the whole house base on the forum recomendations as I can use all the same filters for them.

Is it advisable to do so for the whole house or should I mix with a AX 40?

If I wanna place two XM 2 in a room is it still advisable or should I mix?

Looking forward to your reply, Thank you

ug/m3 concentration reading. Anyway, the reading...just take it as a very rough relative number.

Hi all,

I just brought the Sharp KCD 60E with humidifer function. However, the display keep showing humidity in my room around 50% to 60%. But i got my other humidity measurement devices all read about 30% to 40%. Does anyone having this problem?

Just a thought: If the air purifier has a humidifier function, would it mean that the reading at the device will always be higher compared to elsewhere?

You can try doing the salt test with your other hygrometers (assuming they are more portable), that will give you a basepoint for comparison - https://www.stevejenkins.com/blog/2...grometer-humidity-sensor-using-the-salt-test/

Personally, I find that the built-in sensors in devices tend to be more 'rough', compared to purpose built devices.

Why is that so? But will it have a big difference of 20%?

Anyway i got 3 hydrometers which is +/- 3% so i think the hydrometers are quite ok.

Hi,

my 2 samsung ax40 purifiers have been showing red lights, especially the bedroom one, even more frequent. I wonder if my location's air quality is so bad. Last time, there was construction but it has since ended. I've cleaned the outer layer filter too. There's no change fliter light on.

Anyone has similar experience? Thanks.

wow been reading this thread for the past few days. good information.

My mother has chronic sinus and asthma. I feel the air in the house is always dirty and dusty.Through this thread i learnt abt non ionizing air purifiers. which is what I wish to get for her. I dont wish to splurge but neither do i want to scrimp on something that might improve her health.

I dont want to take any risk with blueair. Is honeywell the only good one out there?

Something around 500? Any recommendations for a non ionizing one? will really appreciate any advice.

Something quiet, and does its job effectively. maybe something better than the 0.3 micron standard? if affordable as well. I heard that alot of harmful particulate is 0.1 micron etc - not sure, just a hearsay.

u realize u are showing a video of a vacuum in a sealed environment right?

Honeywell is a good brand. But is not quiet. U may wish to go eg. Best Denki and hear the “sound” from their display sets to have a feel of it.

Unable to advice what’s the best suitable purifiers for ur mum condition. Perhaps others could.

Yes, just showing that certain vacuums are capable of doing that. Air purifiers are also useless if one leaves all their windows open mah

 

[Asakura]

cos there are hepa filters in vac these days
to prevent the exhaust from releasing dust back.

Although it's important to note that a vacuum with HEPA filter =/= HEPA certified vacuum. A full HEPA vacuum needs to have a fully sealed airflow system together with regular replacement intervals.

i bought honeywell 170e. Its great. Can feel the air better. In fact, ppl who cam over said the air felt lighter in the house than outside. and surprisingly, its cooler also maybe because there is less dust etc.

It is noisy but it works great. during sleep, i switch it on at low which is fine. at high
