Cutting the pre-filter is a real pain. I am running each I bought w/o the pre-filter. I cannot see that the permanent filter is collecting any dust?

I vacum my original prefilter and I can also use it to size the new roll of pre-filter sheet when I ut it.

I agree that cutting the pre filter is a pain. You have to measure and cut it to fit, but I guess it's supposed to work. I also vacuum the original filter. To be honest I don't notice the difference.I wish I could find an air purifier that worker liked my long lasting last one that I bought at Lowes.....but that was about 4 years ago and can't find one like that any more.

Dear Sharon, When I did locate the filters last year, I found that they cost almost as much as a new unit, so I bought a new one. Really hard to throw away something that works; built in obsolescence to the max. And I suppose I will do it again next year.

Yes. Some even replace the pre-filter with the old post filter and put a new filter in the post filter position - but I do not trust that. I want to protect the expensive membrane and we have horrible water anyways.

You did nothing wrong. The filters suck. You would have to run them for days until they clear out. I gave up. Glad it was cheep. I went to Petco and bought a Tetra whisper in-tank Filter. Cost a little more but works just fine.

I recently washed the post filter and the samething happened. The suggestion regarding blowing out the filter with an air compressor worked perfectly. Its been a month now and the filter stays in place. I believe the washing of the filter (even when the directions are followed) caused the dust/dirt to harden over the pores so the positive pressure just blows out the filter. If you don't have a air compressor, try those computer dust cleaner or wash the filter more aggressively than what the dyson instructions suggest.

I haven't yet had to replace the filter. I don't use it that much. My filter is a permanent filter and I just empty it in the trash when I use it.

I haven't experienced this problem yet...be sure to rinse the filter as instructed prior to placing it in place; and be sure you haven't installed it backwards...not much help--I know, but all I can think of.

Hi! I recently experienced a similar problem! I had removed all the filters (there are three removable ones - two foam and one white paper), washed them all, cleaned everything off the beater bar/roller, shook out the tube/hose, even unscrewed the bottom and cleaned out whatever I could find there too! Still, as soon as I turned it on, it was going to red! Grrrrrr I FINALLY found the problem. You might have already checked this, but just in case, sharing it here. It might help you or someone else. When looking at back of the vacuum, on the right side, BEHIND the main tube/hose, you can see the tube attach to the black vacuum base which feeds into the clear body where the dirt goes in. I could not see any clogs anywhere. BUT - this part of the tube/hose COMES OFF - it is easy to overlook, but it twists and releases. I did that as a last resort, and found my problem! There was a piece of paper in there, and all kinds of dirt and hair (we all shed some and have two cats) were packed pretty solid behind the paper! It took a tool like a crochet hook to get it all out and unpacked! (I have a metal "tube turner" for sewing, which is what I used, but anything super thin and long can work, as long as you do not go THROUGH the hose.) I took an amazing amount of junk that had not come out when shaking the hose, cleaning things, even taking the rest of the vacuum apart... it hides in that last curve of the hose! I hope this helps someone else, because this is a great little powerhouse of the vacuum that is perfect for our little townhouse. But the clogging does happen sometimes, and I've now found the FIRST place I'll look, instead of the dead last! ;-)

I bought replacements w the vacuum but I haven't had to use them yet. Instead when I go to empty the vacuum, I also clean out the filter (I use gloves and a face mask, I def wouldn't do it without those things).Otherwise, I'd probably switch it out every month or so (I use it to vacuum my studio).

Next time improvise a filter in front of it, like a cloth or some screen on it so it won't get dirt, and you just need to clean the filter you had place. :)

it is my opinion that your R/O membrane is not working properly. I have only used Watts (Phoenix) filters in the past, and when my system was new, it reduced TDS by 92% or more. After many years, I replaced the membrane with a new 75GPD filter, and my rejection ration was 94%. I expect this new filter to last at least 10 years, but it cost $115.00. It would appear to me you got what you paid for, and the results seem to be very poor.

I think because your filter is impeded. Try removing the filter and clean off the debris.

What I did was vacuum the actual blue filter thoroughly as it really didn't look very dirty even though I got a "change filter" message. Then I washed the plastic grid piece it fits into thoroughly and let it dry. I reassembled it and still got a change filter message. However, I discovered there is a tiny "reset filter" hole near the top of the inside of the unit where you place the filter. I stuck a paperclip in the hole and pushed, and now it's behaving as if it has a brand new filter! I think maybe if this is done on a regular basis that you can get a lot more use out of this unit, even though the filters are "no longer available."

For the pre-filter to fit any model filter it needs to be cut to size. Its a messy job because tiny pieces from the cut spread easily throughout the work area. After gaining some experience, I made a cardboard templet and using the part of the stick on strips provided, glued them on the templet. I next laid the large floppy pre-filter flat on a large work area and placed the templet w/stick on strips facing the pre-filter on top. This firmed up the pre-filter material making it easier to cut a more accurate duplicate. A lot of work but found it necessary because pre-cut to fit pre-filters seem not to be readily available, well not for my older model filter. All said and done, it works. Good luck with your search for a pre-cut to size. Can't find one, hope this info will helps.

The box I purchased had two filters in it. The prefilter material is a little taller than the filter in my 50250 but it wraps exactly around like the original. I trimmed it to exact height of filter and have about 1/2 the filter height left. So with the two pack, I am hoping to save the clippings from the two to put together a third. I wished they made them to fit. no cutting required.

Not sure what you mean? Mine appears to be working as expected - still collecting dust per my black filter

Jeff, Does your filtration system have a light (red/yellow/green) that indicates when the filter needs to be changed? Let me know if you do, as I may have your solution! kkt
