These air filters work great with my unit, they fit perfectly and are holding up well. I know some have mentioned that they change mine every 6 months, I personally change mine every month or month and a half depending on how much traffic goes through my house. I double checked the AC specialist who services my house once a year to make sure these filters are good and up to date and he said yes and that the inside of my unit was incredibly clean. (why do I change them so often). Before putting it in the device, I write the date on the outside of the filter, lightly spraying Lysol on it. Then, for a little extra allergy relief, I stick it in and let it do its job. Never had a problem with them losing their structure or falling apart. Great purchase for over a year and I am happy with them.
