These work for first 10 days, then I hear buzzing. Perhaps sound of cardboard hitting intake. Which filter will resolve this on new 2.5 ton HVAC?

I have not had this issue with these filters. Is it possible the filter slipped out of the slot holding it. I have had no problems with the filter, been using them about 2 months and I am getting ready to replace it with a new filter

I've had best buy out twice now. The first time to replace all the screws in the back of the tv and that helped for about 1 week and the buzzing or humming sound came back. Best buy came today and replace one of the boards on the tv and i'm hoping this will fix the problem.

I haven't encountered this problem. The problem I have occasionally is, at some time after installation I find air has somehow gotten into the line and causes a terrible rattle and noise. I have been able to get rid of the problem by disconnecting and reinstalling the filters. Sorry this doesn't answer you question. Does it always happen? Maybe there is something floating around that blocks the flow when you open turn it on too fast.

Hi Barbara, The only place these things will rattle is in the impeller assembly, it sounds like the impeller is not correctly seated in the housing and not making correct magnetic contact with the motor, as a result your impeller isn't turning enough rpms and not drawing water up through your intake. If the water level in your filter has dropped too far you may have lost your prime. Before taking the impeller apart, make sure you manually fill your filter with water, then turn it on and see if it draws water. If it doesn't, don't hesitate to take it to your local pet store and ask them to check the impeller assembly remember, they don't want to lose your business. Good luck.

Not sure how long you've had it but I've had mine for about 8 months and it did make a buzzing noise about 5 months in. Once I cleaned the filter which is located on the back lower portion, it stopped making the noise.

I purchased this for a classroom that had a 3.5mm audio wall plate to speaker that was humming. It did not resolve that issue. For home components I would get a quality a/c line filter, or even try replacing the a/c outlet with a higher quality one. See PS Audio.

I honestly have no idea. That being said, I was concerned about that too. My solution was to put in (2) filters that were one pipe diameter larger then my inlet piping.

Go here to get a replacement adapter: http://www.pur.com/support#request. I had to make a separate request for each filter I have and they sent them really fast - little over a week I think. You get metal A and plastic B, C, and D adapters.

I have three units, and I've not had this problem. Could it be the intake is obstructed? If you use peat pots, it is possible some of the material from the pots has plugged some of the misters. I placed my pump inside a nylon sock to filter out any particulates.

I just run these straight up and replace them. A pre-filter is a good idea if you have room.

My husband just dealt with this today. Apparently, somewhere in the back part of the filter there are some tiny holes in the plastic. They get clogged easily but it's essential they stay clear for it to work. He took a pipe cleaner and cleared them out. Now it runs fine again.

Yes I had the same problem and ditched it and found a better humidifier. Our unit leaked from the very same spot. Other people have had the problem. We've had this one for about 6 months: Crane Drop Shape Ultrasonic Cool Mist Humidifier with 2.3 Gallon output per day and it seems to be working well. No filters. It's a little bit of a pain to clean, but a little bleach solution and voila, it's clean. For our needs, this has been a much better humidifier and NO LEAKS!!!!

Try pushing the prime button while the filter is running. It will help purge the excess air from the system. If it doesn't help, the company that makes the filter is really good about helping you fix any issues with the unit even if it means sending you a replacement. I had a problem with my filter leaking and they sent me another one right away. Since then I have had no issues with the filter.

I found the prefilter to be a bit loose fitting as well. My laser particle counter confirmed that the unit was blowing about 1,200 particles per cubic foot, indicating that some air is bypassing the filters. I scotch taped the entire prefilter around the edges, and the count dropped to about 100 particles, so almost a complete seal. I would recommend you try this to get better results.

I have used these filters for the past 1 1/2 years without any problems. Sorry you encountered a problem.

I have the PN50B650 and no buzz. I have owned the set for about 6 months and have not had any problems. I would try an exchange before giving up on the Sammy. I really like mine.

I replaced the filter with no problem. When I did so there was an audible "click". The only suggestion I would make is check the filter to make sure it's the right one.
