Can this be used for 90 days, as the package says, or should it be replaced more often?

check your filters monthly. In the spring and summer, you may need to replace them more frequently, especially if there is an allergies sufferer in your home.

When I first used them I changed them at 90 days. But over time I noticed that they were not that dirty after 90 & I have left them in longer. I change them three times a year now.

Rule of thum is 90 days, but I check it every now and them, if I think it's dirty out it goes 90 days or not. These trap enough dirt that will let you stretch that yearly cleaning on your coils. For even better results, install that bacteria killing light that goes in your air handler. (forgot the name) you can find out about it right her in Amazon. Very inexpensive for everything it does.

I have 2 indoor cats and run the circulating fan 12-18 hrs/day, so I change it monthly as to minimize air flow restriction that could increase the load output of the blower fan. Filters are inexpensive compared to HVAC repairs.

I had 90 days. Contact the manufacturer if your purchase is within your warranty period.

I think it's the standard (90) day or possibly one-year. My first one failed rather quickly after the purchase so when I returned (shipped back to manufacturer) there wasn't any dispute. The replacement one is still working for the most part but still the quality isn't spectacular.

That should be no problem. It says on the packaging that it's to be used within 18 months after opening, mine is still good after more than a year now.

It starts at a 90 day from date of purchase; then goes to a lifetime at a reduced charge for replacements. I have always had good luck with the replacements. Never had an issue before 90 days so have only dealt with the lifetime aspect.

A paper in the box says that there is a 90 day warranty. I used this after I got it about 8 months ago and then didn't need it again until a few days ago at which time it did not work.

I don't think ANY electronics are warrantied for more than 90 days but to help you out I installed this myself. After taking it apart and many times thinking I was WAY over my head it went together with not a single problem. And so easy anyone really anyone could have done it. I'm not sure how long ago I put in in but the computer is working just fine. Als if you contact the company they will help you make sure you get the correct one.

Linda, My unit was factoy re-conditioned. It came with the original factory warranty for new product, don't recall if period was 90 days, 1 or 2 years. You should also consider getting 1 or 2 extra chains. I've used mine quite a bit so far this year and am on my second chain already.

Supposedly it lasts for a year, but good luck getting them to replace it. These things tend to die, and they only replace it on a very limited basis.

Seems like it may have had a 90 day. I really like mine. Still runs great. Debbie

There is a cartridge that can be replaced, I don't know how often it needs to be done! I haven't had mine long enough!

It depends on the weather The hotter it gets the more often it needs to be changed When it is in the 70 and 80 30 days is just fine but when it gets above 90 for a extended time change every 15 to 20 days.

I replaced mine when it was not working anymore. Otherwise if it's cleaned well, you don't need to replace it often or at all.

The instruction says 10 minutes for 3 months so 90 days but so far I've had it for close to 6 weeks running about 15 minutes a day. It seems like it's still going strong. I'm about to order the refills just in case and probably open it up to see if I need to change it soon. I would say just to be safe change it after 2 months, unless you take quick showers daily. I would recommend it to anyone though since I've gotten 4 other co-workers to get the shower head :)

In most case you can buy the warranty up to 90 days after the product is purchased.

A few weeks, I think they suggest replacing it every two weeks, but I've used it for six weeks with no complaints from my pup. Depends on weather and usage I would guess also.
