Ease of use

This fit great, and I will be buying more. It was the cheapest I could find that I knew would fit based off of other reviews.

So easy to install. What a difference have purified air is.

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

Nothing

Works well with our Germ Guard air purifier

I purchased these for my home because my father was coming to visit and I also suffer from bad allergies and sinus infections. These definitely helped keep dirt and animal hair at bay. Last about 6 months before needing to be replaced.

If you need this replacement for your product that uses this, then this will work great. Have no complaints easy to replace the old one. Amazon prices this competitively with other retailers.

I liked that this one is the real product that actually fit into my air purifier. The price fluctuates every so often. It works as it is supposed to.

Some last a bit more than six months and others just four. It depends on the allergens in your air.
