VEVAPremium Vacuum Filter Set with 2 HEPA, 4 Foam, 4 Felt Filters for Shark Rotator Navigator Duoclean Lift-Away Upright Model NV650, 650W, 651, 652, 750W, 751, 752, 831, 835; AX950, 951 & 952

Since I just received the AZ1000W this month I have not tried the filters. I wanted to purchase some extra filters so I could rotate after washing the dirty filters allowing them to dry thoroughly. I was looking at two different suppliers on Amazon, one being Veva. The other supplier did show measurements that looked very close to the originals in the vacuum. The suppliers info indicated the filters were compatible with the AZ1000W. The images showed they were designed for the NV650 and I cross checked on Shark's website to see if both vacuums used the same filters under accessories--and they did. The price was a little lower for the unnamed supplier but my ultimate decision was based on my review of the suppliers websites. I was more impressed with Veva. FIT: All of the filters (HEPA, Dust Cup Cyclinder and Flat Disk) are identical in size compared to the originals. In fact, the HEPA was so close in appearance one would think it came from the same manufacturer as the originals and may have? The mfg materials appear to be the same and the only difference I noted on the foam filters was the pull tab for the flat disk filter. Unable to comment on quality compared to the originals at this time. UPDATE 7-20-2020: I have now been using these filters for almost six month now. I originally purchased the filters in Feb 2020 and have been using them on both my Shark AZ1000W and my daughter's unit I purchased for her. I have washed them a number of times now and they are holding up fine. I have been washing them (Not HEPA) with liquid dish detergent to get them cleaner. I think the instructions may have said to just wash in water but I have not had any issues. VERY PLEASED with the filters.

Great filters , OEM or better materials used in the manufacture of these filters . They fit perfectly , and this manufacturer's HEPA filter actually seemed to have increased the amount of fine dust that my vacuum collected which caused me to have to shut it off and clean that filter plus empty out the dust bucket sooner than I have before . Excellent value for the price that shipped fast and secure in an adequate poly bag .

I ordered these so that I would have replacements on hand for my vacuum cleaner. I noticed this last year that the foam filter that came in my vacuum is starting to break down somewhat. I decided to get replacements so that I would have them on hand when the time came to replace the originals. These seemed like a decent price for what you get and I know from the originals that the foam and felt filters are definitely easy to clean.

I was hesitant to get that many filters for the price, but so far quite pleased. Great value!

These seems like an excellent replacement for the factory filters. The overall dimension of the foam filter is about a 64th of an inch smaller, than my original filter. The only other difference I see is the hapa filter does not have the screen part over it like the original, As others have pointed out, but I don't believe this will affect the performance. It fits nice and snug over the post of the filter holder, which is the most important, For the air is drawn through the foam filter and through the holes in the post. The phone filter holder has a rubber gasket on the bottom of it that seals against the housing, So it doesn't really matter that the foam filter itself, is slightly undersized. His vacuum is working great. I would definitely buy them again.

Correct size for my vacuum. Filter works very well and actually helps with the suction. This is the second time I have purchased these and will continue to!

This is the necessary filters for the Shark cannister vacuum.

It fits perfectly, we technically have a brand new vacuum cleaner now
