This is the third filter Ive used for my air purifier and They usually last a long time. I usually go 7-8 months before the purifier tells me it needs to be changed. The replacement times might be different for each house since dust levels might be different. I live in a very old dust prone house. They do a great job and every so often I vacuum off the dust thats accumulated on the back of the filter just to help make it last longer.

Perfect for my unit.

Works well with our Germ Guard air purifier

This is a great product

This product was easy to install in my air purifier. It definitely works to clean the air...just wish it wasnt so expensive!

love this worked perfectly

Back in October 2019, my partner was diagnosed with stage 3 colon cancer so we had to do everything HUMANLY possible to keep this dust under wraps. WE WERE IN THIS PRE COVID. so when covid came we already had everything before the craze. Truth be told we have 3 cats and at the time a dog. BELLA our dog got canine lymphoma 6 months before my partners diagnosis so they were both going thru chemo AS I SAID we have 5 and a few ionics. SO IT IS QUITE IMPORTANT that we always change these filters IF YOU DONT HAVE A https://smile.amazon.com/GermGuardian-AC4825-Sanitizer-Allergens-Guardian/dp/B004VGIGVY/ref=pd_bxgy_1/142-4804164-4888103?pd_rd_w=E7zA2&pf_rd_p=c64372fa-c41c-422e-990d-9e034f73989b&pf_rd_r=SX4W39TQD1FFJE474ZEG&pd_rd_r=3151aea3-887f-4bc6-9341-ecd37bad562c&pd_rd_wg=7U3OC&pd_rd_i=B004VGIGVY&psc=1 I WOULD GET ONE 1 there not too big but to be annoying to try to place 2 they really keep some dust . because our house has hardwood so its SUPER MEGA ULTRA dusty. it helps when we take them all apart to change and clean filters if you dont put them all back right away THE DUST WILL settle everywhere 3 not too noisy on 1 or 2 but 3 {to me ICANT } 3rd LVL sounds like a light handheld vacumeweaksauce but annoying to sleep to all and all WE OBVIOUSLY will and have bought them again

I bought one of these a couple of years ago. It works! I have now added another one. Its giving me just as much help as its big sister. Same model.

I have used my germ guardian for years and these filter replacements are great! There isn’t any off gassing or weird smell like some other filters I have used in the past. It is easy to change out and I have noticed an improvement in my allergies. I actually miss my air filter when I travel! I accidentally bought the (purple?) pet version previously and that one is great as well.

Original part works great.
