HQRP HEPA Exhaust Filter compatible with Eureka Endeavor NLS 5400A AirExcel NLS 5403A Airspeed Zuum AS5203A AS5204A Upright Vacuums

UPDATE: I noticed the filters had changed so after days of getting one reply per day, I finally got the answer I was looking for. They are not as good as they use to be and the answer I finally got was "We contacted our suppliers, and, indeed, the filters were modified". So unfortunately the efficacy is not the same, but they are still better than the sponge piece that comes with the vacuum.First off, do not worry about the prop 65 warning label. This is completely overused.I've been having dust mite allergies and decided this was cheaper than buying a new vacuum. This works with eureka airspeed zuum as5203a. The filter is a tight fit and I have to use a non slip gripper pad to take it out so I can clear any debris. When you close the lid it also feels a little tight, but it does close and the lid clicks into place. It will only fit one way so if you have any issues then flip it over. Make sure to push it down firmly so it can create good suction. I feel like I have better suction now than when I used the sponge it came with.UPDATE: I've ordered other filters like this from different suppliers and they are NOT the same and they don't work as well as these ones do. I had one of these filters left after using another suppliers filters and after putting this one in I cannot believe how much stuff the other filters were leaving behind. I changed this to 5 stars. I also want to help people with removing the filter as this is very difficult. I wipe WD40 on the plastic side that connects with the debris tank and make sure to wipe away any dust or dirt from inside where the two plastics touch, then when I need to exchange the filter I use a pliers to pull out the old one. The oil makes this process so much easier. I know to some this might seem like a lot of work but if it saves you from spending hundreds on a new vacuum and does the job sufficiently then it is worth it!

Why this filter is included with the filter package I bought is misguided. This filter will in no way fit my vacuum but the other two filters included in this set do fit perfectly. How can a filter for anotherproduct be included in this package?

I have a Eureka Multicyclone with the HF 16 filter. The original filter was an easy fit. This was slightly oversized and tended to jam. I struggled to get the new one in and had trouble aligning everything. I finally got it to work, but wouldn't purchase this again and wish I hadn't purchased this one.

I took a chance getting this but it works for my vacuum. I have an older Eureka multicyclonic but I love it and was happy to find a less expensive filter that works. I had a little trouble putting it in (probably just me) but it fits and my vacuum is working great again.

My wife had been looking for this item and could not find it so we checked online and had it in a couple days. Works and fits like the original.
