Fit perfectly, no problems

Every time I change the filter, I am surprised at how much dust is trapped on the filter instead of being inhaled by me and my family members. My Germguardian device is fully compatible with this filter. Were subscribed and get them monthly (4 units in the house). One thing is puzzling me though. Why the bundle packs give worse price per item than ordering a single filter?!

I’ve been using these filters for about two years now. They work very well (see pictures). They capture room dust, loose carpet pile, small particulates, etc. So much material it becomes caked onto the filter over time. Ever since I began using, I’ve noticed that I don’t have as many breathing issues or asthma attacks. I keep my filter unit in my study room as this is an ideal location. I have it running continuously even when I’m not in the room. I would advise anyone that has breathing problems to use a unit that can accommodate these filters.

I purchased the GermGuardian and replacement filters bc my daughter bought it for her house. I have not replaced the filters as of this date. However, the filter appears to be easy to install.

Works great

Correct fit and lasts a good amount of time

Judging by how filthy they are when I change them, these filters are really pulling in dust and particles in from the air. And they last a long time too.

Easy, clean, lightweight!

Says change filter when red light flashes. Red light continues you flash even after installing new filter. Why??

To filter the air, I have taken it everywhere I go , it makes it easier to breathe, and it is priced right , easy to change the filter
