Not sure of the question but something that a lot of people forget is that for things like air purifiers and AC units they really only work to their best efficiency when in a closed environment. That is to say for best results all doors and windows need to be closed, if they are left open air is continually coming in from outside bring in more of what you are trying to remove.

Oh yes, sorry, i didnt explain my question clearly. I was tired when i wrote it last night. Yes, i was wondering how much electricity it used, but i’m sure it wouldnt be much. It’s only small, 2 kw. Thank you for your reply.

Thank you for your reply. I didnt explain properly. Yes i keep my door and window closed with it on, i dont think it would take much electricity. I just needed reassurance.

I know the tired feeling so don't worry or apologize:)

2kW uses 2kW/hr so for 24hours you would use 48kW not sure what the cost of electricity is in the UK now but it is usually stated in cost per kW/Hr so a simple multiplication will tell you the cost per day. I think that cost is relative and that quite often the benefits in health and comfort make a little expenditure worth it.

It’s 2W not 2kw! I read it wrong. So i dont think 2w will take much elec. but like you say, i don’t care, because if its helping what does cost matter. Thank you for replying.

:) then divide by 1000 the value the previous calculation gives and that will be the real cost:)

Ive worked it out now,( long time since i did maths at school!), it costs approx £3.70 per week if i have it on 24 hours a day. So thats nothing if it means having better air in my room.

It would be cheap at twice the price:)

I believe you are asking how much electricity they consume? If so I can assure you that they use very little. I use both a Air Purifier and a De-humidifier and have hardly noticed any difference in my electric bill. Hope this helps. LLAP, Eric 🙋👍

Yes, thank you for your reply.

What’s the model number, the ones I have seen use very little circa 20w/hr and the running cost are miniscure. You state it’s rating as 2kW which is 2000W and excessive and a figure more in line with an electric heater. It maybe the 2kW is the rated current and not necessarily the running current. If the running current is indeed 2kW and it runs continuously for 1 hour without any fancy air sensors cutting in off for short periods similar to the way a thermostat works in an heater then the cost per hour would be approx £0.30 pence depending on your energy tariff.

Hope this helps but I suspect you have misread something in the specification.

in reply to Leccybill

Yes! I misread, it is 2w not 2 kw. So it shouldnt take much electric. Thank you for replying.

Back to school for you then: 2w per hour is 24(hrs) x7 (Days) x2(Watts) = 336 Watts per week

At tariff £0.15 per Kwhr. Kw is 1000 watts, so that's 15/1000x336 = £0.05 per week.

Enjoy :)

🙂 Maths wasnt my favourite subject. Thank you for the calculations. That sounds very inexpensive. 🙂

2W isn't much consumption.... are you sure that is right?

in reply to soulsaver

It says in the leaflet ‘max power 2w’. Its only a small hepa air purifier , about 14 inches high and about 8 inches diameter, and it oscillates.
