Air purifier?

I bought a xiaomi airpurifier using direct shipping, freight charges only RMB61. Got rejected outright and now handling returns. Do not buy through direct shipping, go through consolidate shipping through the central warehouse and pay RMB 235 using 4PX.

My Mfresh 8088A is bought using this method

Thanks bro, for the info.

I'm more concerned if that TCM smell is actually harmful or not...is it just a fully-spent AC medium releasing what it'd accumulated?

If you meant releasing the particles trapped, I don't think so. I put my SamoAir at the outlet of the AP and it was able to register 0 ug/m3 after a short while. But the smell could be due to the trapped particles.

Don't think its from the AC. My Sharp filter is separate from the AC and the smell is coming from the filter itself as a new filter + the old AC does not emit any smell.

So will you fellows swap to an entirely new piece of filter once the TCM smell starts recurring consistently?

On the other hand, anybody has experience using a penknife to separate the AC layer of their AX40 original filter?

yes not from AC. My LG AP has its AC filter removed but still got smell.

Yes, I do replace the HEPA once I find the smell to be somewhat intolerable. In a small bedroom room, this can be noticed quite easily. Living room, less so I guess.

Yep, can use a penknife/kitchen knife to just cut. Slice the masking tape, it will detach.

 

[nwh_sg]

so has anyone washed the LG 'washable' hepa filter yet?
edit: Nvm, saw WRX's posting on the subject dated May 15

Do note ours is a single channel, and it's really super agaration. It uses some DSP processing which I am sure where is the actual sauce (free) that they gotten from.

Our $60 devices to 6k devices using laser scattering to 40k BAMs all need RH control. We use a hair dryer.
In places like NE China, the air is much dryer 90% of the time now, so the MIC cheapies stand a better chance there out of the box, naturally.

So can't compare the conditions in China vs ours.

Thanks. Is the PM2.5 reading from Samo Air or similar same as what NEA provides?

It actually over-reads by a certain degree without drying the air with a hair dryer. NEA has some 1kW of inlet heating for its 16.7L/min sampling volume. But it's pretty predictable most of the time and gives a very good idea on what is going on at present.

Not sure what this "TCM" smell is...but i found out why my samsung ap giving out weird smell... its definitely cause i turned it on in the living room during the >200 psi haze period. After that, the smell started and keep getting worst and i finally swap out a new one. I didnt throw the old one away yet.....thinking of swapping it back again when the psi hits > 200.

 

[kimsim]

Should be the Hepa remove the smell, mine don't have it issue, cause fully AC at all times, even non haze periods.

My one only using sharp KC-D40E model as well, so far so good, try to be replace new Hepa filter if you can.

Otherwise to be cycle and cycle the fresh air into bad air exhausted out.

So until now i still havent buy an ap
Passion gadget until now havent restock
Thinking want get from 1stshop or just happymall for ax40
Since now got deal price 299

Anyone knows a good place to get a snake plant?

Natural air purifier to supplement my AX40 and remove CO2 hehe

I was looking into this, found a study that mentioned something about some of these plants, while they help to remove some VOCs, they (or the soil/pot) also release some VOCs too. Impact on humans unclear, just FYI.

A research team at the University of Georgia’s Department of Horticulture conducted a study to identify and measure the amounts of VOCs emitted by four species of popular indoor potted plants and to note the source of VOCs and differences in emission rates between day and night. The four plants they chose were Peace Lily (Spathiphyllum wallisii Regel), Snake Plant (Sansevieria trifasciata Prain), Weeping Fig (Ficus benjamina L.), and Areca Palm (Chrysalidocarpus lutescens Wendl.).

Samples of each plant were placed in glass containers with inlet ports connected to charcoal filters to supply purified air and outlet ports connected to traps where volatile emissions were measured. The results were compared to empty containers to verify the absence of contaminants. A total of 23 volatile compounds were found in Peace Lily, 16 in Areca Palm, 13 in Weeping Fig, and 12 in Snake Plant. Some of the VOCs are ingredients in pesticides applied to several species during the production phase.

And it turns out the plants themselves aren’t the only ones responsible for the release of VOCs. Micro-organisms living in the soil were also to blame for releasing volatiles into the atmosphere along with the plastic pots containing the plants, which were the source of 11 of the VOCs – several of which are known to negatively affect humans.

The study also found that VOC emission rates were higher during the day than at night in all of the species, and all classes of emissions were higher in the day than in the night. This was expected as the rate of release is determined by the presence of light along with many other factors that affect synthesis.

The study concluded that, although ornamental plants are known to remove certain VOCs, they also emit a variety of VOCs, some of which are known to be harmful to humans and animals. However the researchers did go on to say that the longevity of these compounds hasn’t been adequately studied, so their impact on humans is unknown.

Snake plant is Sansevieria Trifasciata.

Faint

Thanks for the information! Will stick to my little money plant (which might also have the same problem) for now

Which is why you need to culture your own microbes or go hydrophonic for good airflow in media.

Similar concept to "Botanicaire"

U will need about 5-6 waist height adult snake plant. Please avoid getting dwarf cultivar. Good for office desk but not bedrooms, unless you plan to be surrounded by it.
