How many years does this last before it has to be replaced?

Check for a warranty, if you would be organized enough to claim on it. FWIW, we had extremely good service out of the ones we bought years and years ago. Not sure if manufacturing has changed. My child was a toddler when we bought them, and he's almost out of the teen years old now. A few times through all those years, we've noticed a few bugs and unplugged it and plugged it in and it's started working again; or plugged it in for a couple of weeks in a different area of this house when I started seeing a few bugs in far flung areas. (My limit is 3 bugs before I react.) We JUST ordered a replacement for one unit. I started seeing a few bugs this Summer. The lights on the unit were not acting as they had in the past. (There's a pattern to the lights if you watch it.) This time, unplugging it did not reset it -- not sure if it finally failed or if that unit got hit by lightning. This time, the electronics guy here said it had really failed. Of course, with any electronics, no telling if the newer made units are manufactured elsewhere or with different components. So I can't predict quality of the newer units. It's worth a try imo because two of these units have kept my large house bug-free (other than spiders in the ceiling and ants coming in the back door), never sprayed any insecticides, for... 16 - 18 yrs? I hope the new units give as good service! (Said engineer is going to open the failed unit up and see if it's simply a capacitor or something repairable when he gets time. Just curiosity. The schematics are available online now if you search for the patent. But we just went ahead and bought a new unit. )

It depends on how much you use it. Mine lasted a lot longer than 2 years. But I used it even after they become somewhat worn. The replacements were very easy to install and work great.

It depends on how often you run the unit and how much dust/allergens it's filtering out of the air. If it is always running then generally the filter should be replaced every 6-8 months.

I'm about to order a new one to replace the one my wife and I bought before we were married, which means it lasted more than five years before we thought that it might be time to replace it.

I've been working in IT for 20 years, and I've never heard that. If it wears out, you can replace it.

Depends if you purchased New or Old or Refurbished or so.They do last 3-5 years depending on how well they are looked after.

some day you will have to replace it but it will be a long time before you have to

The owner's manual says replace every year for heavy use, every 2 years for normal use and every three years for light use. I use it only at night as opposed to the recommended constant 24 hour condinuous use, so I think I probably waited 4 years, which was much too long as it was really dirty.

I replace it once a year but I imagine I will depend on the watter quality in your town. I'm in the south of Spain and we use it a lot.

I do not know. I've had mine for a year with no problems. And had the one just like it before this for 15 years.

It uses an LED lamp, so it should last upwards of 50,000 hours. You probably won't ever have to replace it; at 4 hours of use every day it will last you over 30 years.

Yes. It is time to replace it. I have the same problem now. It is supposed to last seven years.

the only answer I have is--it will last way over a year, maybe two or more !!!!

About one year, although the deteriorating quality may not be noticed until after the replacement has been made!

We just replaced our first one after 4 months. Will probably replace it every 3 to 4 months from now on.

Manufacturer says 1 yr. I doubt if we have to replace ours at 1 yr, just vacuum the pre filter monthly. That will make a big difference on how long the filter lasts.

You'll find the mnfc. date on the inside of the unit. The unit will be good for five yrs from that date. My last one lived for almost seven yrs. before needing replacement.
