> 3 dayI guess I did not read well enough but you get 4 filters and each one lasts about 2 months. This is a great value and a great product. You can vacuum the filters once a month to make them last longer, just use a hand vacuum with a hose. These are packaged bent so they have a bit of a memory so lie them flat on arrival.

> 3 dayPrice is good but too big for the filter so I recommend cutting it to fit the length. Also you should really buy the original hepa replacement once a year because it comes with the WHITE and the black filters that are meant for the filter to work well.

> 3 dayPRO: Can extend the life of your primary HEPA filter CON: (Not really a con, just an observation): Unless you put yourself on a schedule to replace this PRE-FILTER to extend the life on your HEPA PRIMARY filter, youre probably better off getting the combined product which allows for quick, clean, reliable replacement of BOTH filters at once.

> 3 dayI recently purchased a replacement HEPA filter for my GermGuardian and didnt realize that it also came with a carbon activated pre-filter, so I also ordered this 4 pack. The quality is the same as the one that came with the GermGuardian branded HEPA filter, although the sizing was a bit different. I do not think I would have a problem fitting this into the GermGuardian, but they are also easily altered simply by cutting them with a scissors. As I had 4 more carbon filters than I needed for a while, I used two of them for another separate air conditioner; I cut the filters to fit and inserted them behind the mesh filter in front of the rear air intake, effectively adding an additional filter where there was none from the factory. As the air conditioner runs 24/7 in the summer, I now had the added benefit of extra air/odor filtration, and the room smelled noticeably crisper. These filters will work for your GermGuardian and are a good value, but be aware they can also be reconfigured for other applications where you might need a carbon filter. I even saw a picture on a website of someone who had attached them to the rear of an oscillating fan to help with filtration! Excellent for multipurpose use.

> 3 dayI bought this filters to replace my AC4825 filters but I’m truly disappointed. First of all the quality is very low and the red light on my filter keeps blinking instead of resetting to green. On the product description, it says that it should work for this unit but it does not. I’ve had to put black tape on the blinking light. I don’t know if the blinking light will damage the system. If anyone knows how I can fix this problem, please let me know. Thanks.
