I don't know that answer, but that air conditioner is really loud. Can't use it at night because it keeps us awake going on and off. The room that we put it in is very small, and it barely cools it. I do not recommend.

It takes longer than 2 hours, I bought a very cheap humidity/thermometer and it showed that it took about 8 hours to show a difference and 24 hours to reach max efficiency. I keep it on 24/7 and it works well. I have two, one for the bedroom and a bigger one for the house.

About 10 min. Just have a fan running I the romm while its running. And when the timer shuts off, the fan will help clear the air faster.

There are 4 zones that you set which are morning, afternoon, evening and night. The system can be overrode at any time however when the next zone hits it will automatically adjust to that temp that is programmed.

I haven't noticed any change. I set it in the window the next day and leave it there. It seems to perform just as well if I use it for an hour or three hours.

I'm going to say a long time. I have had the fan for three months, and I would say I use it 2x per week all night (8 hours). So far it's still going strong.

I´m not sure it can be changed, but I left it shooting the whole night and it cut into 7 files each aproximately 4.165.000 KB. The longer one I took had 01:07:44. Hope It helps.

Just about any air cleaner (cheap or otherwise) is capable of capturing large airborne dust particles within a reasonable distance. Most companies exaggerate their cleaning and purification claims. I think Rabbit Air specifies 2 changes per hour in a 600 sq.ft. room, while most consider 6 changes per hour are required for clean air. So, 200 sq. ft. sounds about right. Check this very good review site for more info and reviews (including the 421A): www.air-purifier-power.com/

I have noticed changes like this too. I think it depends on how many people are in the room breathing as humans exhale co2. Mine will change from approx. 350 to 7-800 within minutes if I am working close to the monitor.

Thanks for your question. Our fans are a 50 thousand hour type. This is 9 hours per day for 15 years. We fully expect them to last the spec'd lifetime. We will always have replacement fans for sale for your unit. As an FYI they are two ball bearing high speed fan. Thanks again.

Pent air says 3000hrs. Switch is on the transformer. Mine is plugged into my ground fault interrupt for safety. Looks great at night. Kids say the bubbles look cool.

The amount of air moved, measured in cubic feet per minute (CFM), on the three speeds varies little. 3460 high, 3320 medium, 3160 low

Yes is has an Air filter alert that is configurable in terms of hours of run time or days. You can configure up to 500 hours of run time or up to 180 days. You can set alerts for service call reminders (up to 360 days between reminders) and you can also set the max run time for UV lights (up to 360 days) if your system is so equipped. All reminders can be enabled/disabled.

I run my unit 24 hours a day on turbo with 8 hours of sleep mode at night. I replace the carbon filters about every 4 months and I just replaced the HEPA filter at about 1.5 years. In my opinion it is worth the cost. The air purifier works well. Kim
