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 read elsewhere that HEPA filters when they are brand new are not very effective. Over time they actually get more effective, up to presumably a saturation point and then get less effective again.I've vaccumed the HEPA filter in this unit with my HEPA vacuum to extend its life by a few months. This seems to work fine. Presumably you'd need a microscope or a really expensive piece of equipment to measure air quality for sure.The charcoal filters are cheap enough and get dirty enough I'd just replace them regularly.

sounds like the motor is crapping out. i used this thing for a short time and didnt like it and went back to old faithful "whisper 60s", they last forever, work great, are mostly quiet, gotta pull em apart and clean up good every once and a while but they really are the best hang on filters u can get. ive been in saltwater forever and have used EVERYTHING you can imagine, stick with whispers..

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.

you are using wrong filter replacements. make sure the filter you use for this system is dedicate for WHER25.

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

Did you double check that the new filters are properly in place? I would take them out and put them in again. Otherwise, call the customer service number for assistance at 1-800-541-6645. I hope this helps.

Yes, I've started having problems with mine after 7 months. I thought it may be the filter but they said not. They sent me three parts I have to try to replace and see if that works. It seems like the don't want to give out new filters. My suction is fine for about 5 minutes and you can see the diffence. There are no clogs but the motor overheats and shuts down. I'll see what the parts do but I don't thing they are the problem.

My hlt 5089s has a loud buzzing sound too. I have requested a replacement from Vann's.

Mine just started buzzing. I have cfl's in my ceiling fan. I turn them off and the buzzing stopped. I just don't know why it just started to do this at this time because I've had this setup for almost a year now. Oh well, thanks to everyone who contributed.

This is difficult to answer. First, is this a new unit that has just been put in service? If so, during the setup procedure did you remove the upper housing and insure the filters were not wrapped with a protective cover? Is, then I suggest that you select each of the 3 different fan speeds and see if the air flow changes. If not it may be a defective control unit. In any case, if you can not determine what may cause the problem and this is a new unit I would call the manufacture and explain the problem to them.

Hi Patricia...I had the same thing happen to mine but the high pitched noise eventually occurred on all of the speeds. It was not constant...it would come and go but it was very annoying. Couldn't figure out a way to get into the unit to see what was going on. Seemed to me to be some sort of lubrication issue. In any event we really liked the air purifier so we just purchased a new one. It works great and it's one of the least expensive on the market.

Master plumber came and installed my humidifier. I asked him the same question you have for me. He said that you will go through a few more filters a year, but not substantial. He also said that that is a good thing because the dirt the filter is catching would be in your house otherwise. The reason is now that you have a higher humidity % in your house the dirt sticks better to the filter and is cleaning your household air better. I agree after one day. The air just breathes clean. Hope this helps and I am satisfied with my unit.

It's probably a dirty filter. You can wash and dry them or buy a new ones for about $12 each (pre-canister and HEPA). Made a world of difference when I cleaned mine--wondered why it ran like doo-doo after 10 years since they're supposed to never lose suction. Apparently they aren't miracle machines--you do need to clean/replace the filters occasionally.

Hi Lexa: Please read my review where this was answered. Yes, I have checked with many and they nearly ALL agree that these "secondary filters" should only be used as necessary on a limited basis. As I mentioned previously, I would suggest only using one or at most two of these to help supplement the existing whole house filter you already should have in your HVAC system. I am only using one of these filters in our kitchen which seems to accumulate more debris. Many HVAC contractors insist that these secondary filters are unnecessary and limit airflow making your fan motor work harder. This could result in decreased life expectancy for your system. My strong recommendation is to change your regular whole-house filter at 30-60 day intervals depending on your use. Hope this helps!

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.

They came on during the first day after installation a month ago .....nothing since. I just wrote the filter installation date down.
