Review: Great air filter replacement - Quality of this product is great. You can see all the captures at the end and how it improved your air quality. Can’t be or it’s not designed to be reused after cleaning it but I had to once and it still worked, but honestly it lasts a while, so one time use is not bad. Great value honestly. Easy to install and let it do its thing.
Review: OEM Replacement Filter - This worked perfectly as a replacement filter for the air filter unit.

**Q: How often do you replace these filters??**
A: I would say at least once a year.  It really depends on how much dust there is in the room where it works.  If there is lots of dirty air I would say every six months. The filters are not cheap so at least take a good look at six months. Sometimes you can take them out and shop vac them and shake them out if they are not too dirty.

**Q: Does it also fit model ac4700b?**
A: The replacement HEPA filter FLT9400 is for model AC9400.  It will not fit in model AC4700.  For additional assistance contact yourfriends@guardiantechnologies.com
