This filter used to last MUCH longer, about a year. Most recent filter lasts a few weeks, til it clogs and I have to remove and scrub it. Why?

It is hard to say why it no longer lasts as long. I have not had that issue even with new filters. It could be something has gotten worse from your water source. Maybe your hot water heater is releasing debris. That is my best guess. Sorry I can't help further.

I haven't experienced this issue. Water pressure seems to be fine. I change mine once every year. Make sure the seller is Amazon. There might me fakes from other sellers.

Don't know. That hasn't been my experience. Has your water gotten harder with more minerals or sediment in it?

I've had the same filter for years. I clean it with an old toothbrush and knocking it against something (outside). I didn't know I could wash it, till I came here to see about a new filter and saw all the comments about washing them.

Depends on your usage, how hard your water is and how often you clean it. If you maintain properly, it should last 3 to 6 months. Google how to clean a humidifier filter. Cleaning it is the key to its longevity.

You use the green scrubby part of a dish sponge to scrub the outside of the filter. Mine clogged in 24 hours and cleaning didn't help. They sent replacements but

I've owned a unit about two years. I replaced the filter after year 1 and just replaced it the second time. The unit seemed to work OK, but the filter does get a little "grungy". I'd say replace at least once a year (I only run the unit during the winter and early Spring months-November to April)

Could it be that it expires if you don't begin to use it for five years? The filters are fabulous, and will last up to 6 months if your water is normal. Ours is hard and full of rust, and it works for about 2 on average. Totally worth the 10 dollars.

We've had ours for about a year. No issues yet, just need to change the filter.

What I've done was made sure that I allowed the filters to completely dry out once a week. And if I remembered made sure to wash the filters. I washed in the dishwasher and worked fine. I may start to wash more by hand with vinegar as that may allow the filters to last longer...in my opinion. I hope this helps.

My first question would be if you primed it according to the instructions that should have come with it (I think they're on the box)? If not, do so. If yes, something I've done to prolong the use of mine is to gently scrub the filters with a clean wet dish cloth. I'm assuming your filtering tap water, but if your filtering dirty water then flow can diminish quicker.

I don't know. I had mine several years and never had to replace filter b/c I cleaned it out and rinsed it off all the time. Try googling it. Good luck.

Sorry, I can't help with this. I returned the item due to poor performance and didn't have it long enough to have to clean the filter. Good luck.

depends on how often you run it and how dirty your air is. Seems like mine lasted about 9 months being run daily. You just wash the pre filter

In my opinion the filter does get dirty fairly quickly...I try to use a brush and get most of the stuff off of it myself rather than replacing every couple months.

Ours did the same thing. If you start googling reviews on it, you will see that this is a common problem. It is almost impossible to get rid of. The company says that it is because you live in an area with REALLY bad water. Therefor you need to change the filter every 1-2 weeks. A scam in my opinion.

I forgot to replace it one year and after a few months too many, I started to smell dust even after vacuuming. Once I replaced the filter, the dust odor went away after one or two vacuumings. It's expensive, but necesary. Would love to know if anyone has had good experience with the generic version for 1/4 the price!

I actually had to upgrade to a bigger filter.....but, I like to clean it every 4 to 6 weeks. This usually depends on what you have in the tank, and size of the tank. I have a turtle, so I have to stay on it and keep it clean.

That's the point of the filter. It will get dirty over time. If you want to extend the time between changes you may want to get a replacement filter that includes the charcoal pre-filter as it will help pick up some of the larger debris and can be hand washed.
