Air purifier?

[widman01]

For honeywell, Carbon pre filter is so cheap... Us$8-10@ amazon. No need to think whether washable or not
I have been using it for my air purifier, aircon, pc and dehumidier. Dirty then throw

 

[mosmos]

btw i noticed that the humidifying filter tend to grow mold like this pic but a simple wash and not using humidifying function for a few days does the job

then the air blowing out ish bacteria or mould spores~?

Yeah, that's another option. Just cut into size and scotch tape into the Sharps or Novitas ba.....

Or if the hand is itcher, try my DIY activated charcoal method.

Try once, sure kena addicted. Mountain fresh air, really.

BTW you all know this cheap PU foam DIY prefilter option right? Much finer than the coarse mesh type.

I removed it, since I don't really whack my a/c to 22 or 23 deg C so no issue with really low humidity. Also have a thermo and hygrometer in the room so I always know how dry/wet it is.

7 hrs ago. I think most times the satellite cannot get an accurate number of hotspots due to cloud cover coz nowadays always raining. So sometimes is just one.... below picture shows 49.

Remember, got rain, also got hotspots.

So now we all ish just waiting for mama nature to dry out the region nia. And then we don't get the variable wind dir (intermonsoon) and we get SW and W most times. Then huat liao.

Everyday use only 2hrs can last 10 years, no issue.

Then habis. Mine is on 12hrs for the last 3 yrs.

Wa got air purifier guru here...

I have calculated ....

The Honeywell 17000 filter quite power actually.

pi x diamter = circumference.

Box dimensions 4.8 by 11.6 by 11.6 inches. So take it to be 10.5 inches diameter.

Circumference = 3.142 x 10.5 = 33 inches.

17000 needs 2 of these, so take 4.5 inches x 2 = 9.

So effective it's a 33 inches by 9 inches HEPA,

The pleating depth of the filter is likely to be 2 inches. See pic below and use a ruler to measure the black part and central donut hole, and take total diamter to be 10.5 inches.

So it's a 33" x 9 x 2 inch HEPA. If a Sharp A40 14 x 9.5 x 1.5" I say can last approx 1.5 years in my real life setting 12hrs per day and 1 dense haze episode per year, then this can last 3 times longer, ie 4.5 years.

4 years would definitely be ok for everyone. Just a little loss in airflow and not too loud (due to increased pressure drop)

This pic would elaborate more

Finally got the power comsumption of the 17000.

Just received Honeywell 17000N today. This is my 3rd air purifier in my house, the others are: Panasonic FP15HU, and Whirlpool Whispure AP250.

I will only talk about noise in this review, since I think most HEPA-type air purifier should almost equivalent to each other, in terms of cleaning the air.

At its lowest setting, the Honeywell 17000N is quite loud, although it does have higher air flow than my other two air purifiers at their lowest settings. The other review mentioned the noise level resemble hair dryer. I agree with this assessment, although more likely it sounds like hair dryer on its lowest setting.

Here is how noisy it is (at the lowest setting): I put it at about 4' from the door in a 11x11 size room. With the door closed, at 6' away I can still hear the whoosh sound of the air purifier.

I am still not sure whether to put this in my son's room, or just put it in a general area like the living room. Will see if he's able to tolerate the noise through the night.

UPDATE: I just used a power meter to check the power usage of my air purifiers. At the lowest setting, here's the power usage:
Honeywell 17000N - 58 watt
Panasonic FP15HU - 40 watt
Whirlpool AP250 - 26 watt

No wonder Honeywell is the loudest of the bunch, and it uses twice as much power as the Whirlpool AP250.

Here's the power usage at the highest setting:
Honeywell 17000N - 80 watt
Panasonic FP15HU - 96 watt
Whirlpool AP250 - 45 watt

 

[WussRedXLi]

If we take a difference of 50W (including slight transformer loss/inefficiency) between this vs say the Sharp or Novitas power consumption in medium/high speed.

$0.275 per kWh incld GST.

50/1000 kW * $0.275 * 12 * 365 = S$60 per year.

Wah, then would be a bit more ex liao in the range of S$50-70 and some of them would have the PSB sticker (safer, at least in theory as it's stress tested locally). Check Sim Lim Tower ba...
