If you have the AeraMax 300 Air Purifier (http://www.amazon.com/Fellowes-Allergy-Friendly-AeraMax-Purifier/dp/B00D8Y1YNC), you will need this HEPA filter as a replacement from time to time -- no other option. If you've had other equipment with this kind of "paper" filter, you'll recognize the look of the tight folds. In some of the vacuum cleaners we've had, they say that this type of filter is washable, and I will try this with one of the used ones at some point. However, given that we use it in the bedroom because of my wife's significant allergies, we'll probably end up getting a new one once a year, or as required. By the way, the 300 has an orange warning light on the front panel that lets you know when you need to change this filter -- or much more often, the carbon-sheet filters custom sized for this air scrubber. One of the few downsides to the 300 itself is the light panel on the front of the unit (upper right corner), which is always on. What we don't need are lights shining in the bedroom all night! I covered the panel with black tape -- but then we couldn't see things like the filter-change lights. So I found a piece of opaque black plastic -- packaging from another product, cut a strip that fit over the lights, and taped it to the machine at the top as a "hinge", with a bit of tape to hold it down at the bottom to keep the lights from shining out. Works fine. I just have to remember to check the status of the filter lights from time to time.

Overall, this purifier is great! We really cannot believe how much junk there is in the air, and how quickly it filters it out.
