how many hours does it last before replacement of batters are needed? how many hours before filters need replaced?

Not sure... I don't use it as an ashtray, but for catching the particles of mineral make-up that are floating around when I apply it in the morning. I've used it every day since I bought it last December, but only for five minutes or so a day. I've not had to change the batteries or the filter yet.

No filters needed ever & last 4 as long as the batteries in it do. Then simply replace batteries.

I haven't replaced one yet! I use it every couple of days for an hour or so.

Depends on how often you run the machine...I run mine about 12 hours per day and I change the filters about every 18 months.

No. You can use between 1 and 3 filters. The more filters you have, the faster it will filter. 1 filter ~ 14 hours. 2 filters ~ 8 hours. 3 filters ~ 5 hours.

"dispose of filter after 40 hours of use or 30 days, whichever is first" - http://multimedia.3m.com/mws/mediawebserver?6666660Zjcf6lVs6EVs6662M_COrrrrQ-&WT.m;c_id=www.3m.com/filterchange

Only about 8 minutes because my kids run them full throttle at all times. I recommend buying a second or even a larger batter 3500 Mih etc. will give you more time.

if you keep the filters cleaned on a regular schedule they should last for many years. check your cleaning requirements (very simple and easy to do)

I haven't had to replace mine as yet (just got it last week). But I will check Amazon for pre-filter and filter. I just checked and Amazon carries the filters for $33.

There are three filters One permanent, two replaceable. You should "clean" and re-use the initial filter monthly depending on the work load. I haven't had this unit very long so I just take the front cover off and visually check the filter. The cover is very easy to remove & replace. The other two filters are expected to last around 18 months. They have to be replaced, not cleaned. When the cover is off there are a series of led lights telling you the condition of the filters. By the way, removal and replacement of the filters is really easy.

Personally I havnt had to change the filters as of yet and my machines run 24/7. I'm figuring every few months or so. The machines do come with replacement filters:)

Do you mean how many years before it needs to be replaced? Or, how long on a given charge? If years, I don't know but it should last longer than any lead acid battery. If you mean on a single charge, I haven't timed it but probably about 30-45 minutes for each battery (there are two).

I ordered this replacement and it works http://www.amazon.com/gp/product/B000B8URLI/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1 I have read that you are supposed to replace the filter 1xper year, but who knows what kind of usage they are basing that off of. I replaced mine after only 4 or 5 months (when I started noticing a considerable difference), but I hadn't realized until afterward that you are supposed to reverse the filter every 30 days. I am hoping if I do that it will last at least a few more months this time.

The main reason you have to replace the cartridge is evaporation. Save the plug, remove the cartridge and stop up the hole after each cleaning cycle. That will prevent evaporation and your cartridge will last about 4-5 times longer. Plus you won't have to fiddle with dangerous chemicals, worry about getting the mixture right, making a mess, starting a fire. Also, remove the foil and tap the hairs out of the head and foil area before cleaning so that there is a lot less gunk to get stuck in the cartridge filters.

Not sure about batter life, Duracell, alkaline, etc. Haven't had mine 4 months yet. You may want to email the company. They are friendly and respond very quickly.

I cleaned first filter out with small scrub type brush and used it at least four months. Neato's replacement filters were too expensive so I went online and got a replica off of eBay at fraction of cost. Got a set of four and figure it will last at minimum a year. Fit perfectly too.

I've had mine for two years & haven't replaced the filter yet. So, I don't know. It depends on how much you use it I guess.
