I agree with William C. Spaulding, Oct 24, 2012 review. Filter does not lock into canister head/dust cup. However William was wrong when he said tabs are too short, it is the gasket on the end that is too thin. The gasket is half the thickness it should be, therefore, does not "push" tabs into the locking notch. The gasket acts like a "spring" locking filter into notches which also seals the filter to the head.

I do design for a living, but this is just such a blatant change that effects fit and function. This would have never happened at where I work and if it did, we would not ship out the part until it was corrected or returned to the vendor. Someone at the manufacturer was trying to save a penny (or less) a filter and turned it into a unusable piece of trash. They could apply a second gasket onto the first to build it up to the correct thickness.

I will not put tape on the tabs because the gasket seal is very important to the performance of the vacuum. Crucial Vacuum needs to stop selling these, refund or replace the "defective" filters with "good" filters free of charge. Then Crucial has to get the supplier to correct the defective gasket or return them to P.R.O.C. (People's Republic Of China), YUP, made in China.

I felt good about buying from Crucial Vacuum because, in the past, I purchased allergen vacuum bags from Crucial. This has left a really bad taste in my mouth in trusting this brand again. When I put in a request to return the item, they expect me to pay the return shipping! I sent them a message requesting a prepaid return label or just refund purchase price. I will update this review, on how Crucial vacuum handles this whole mess.

Update 30 October. Crucial Vacuum is issuing a refund.

This filter was a great replacement. It fit well and works great. Now I can thouroughly wash and dry the unit that came with the vacuum and switch them out. Price was right too.

Take the time to compare your filter with the picture. My original filter does not have that rim on the bottom. I had to modify the filter to make it fit in my eureka speedgold. It is a shame because the filter seems to be made from the same materials as the original. Not sure if I picked the wrong model though.

Does not fit right. The top part with a rubber seal is not thick enough to make this fit right. it sucked dust in the motor and burnt up my unit. i am very upset that this filter did this to my unit. i want a refund and i also want my unit for $144.00 replaced!

I bought this as a replcement for the factory one. The factory one fits snuggle and doesn't come loose. This one has fallen out twice and even when it is connected it is loose and falls out while vacuming.

The filter came in the mail, it looks to be put together well enough, but the rubber gasket on the base is too thin, causing it to be loose inside the vacuum (Eureka Air Speed Gold). It does not form a seal, and may allow dust to get into the vacuum engine. I thought I would try a generic, and I got what I paid for. I would not recommend purchasing this item if you use the same vacuum.

This filter is an exact replacement for the one in my vacuum. Arrived on time and in perfect shape. I am going to get another one so I can wash one while using the other.
