great filter. Air is cleaner.

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

This is a great product

I suffer from bad indoor allergies. Dust and cat fur, to be specific. This filter has helped in keeping my allergies at bay in my bedroom. Plus, you can see all the dust thats accumulated when you change out the filter. Its incredible. Its a good filter, and this replacement fits well.

Works as it should. Easy to replace.

Pleased

So please this filter is so easy to replace!

Great quality and perfect size!

Weve been using these air filters for several years, and after recently reading through reviews to order a new batch I became a bit skeptical. Luckily, my wife bought us an air quality monitor as we struggle with horrid air quality in Denver due to the fires in California. I live in a house with only a swamp cooler and no other ventilation. Every time the swamp cooler kicks on, our indoor air quality becomes unhealthy when it pulls in all that air. So now Ive closed up the windows and am running two Guardian air filters at once to test their effectiveness, and the results speak for themselves. Our air quality is back to good with particulate matter and VOCs, as my brain fog is lifting. Another trial-by-fire was we snuck one of these into my grandmother-in-laws house and closed the door to the guest bedroom. The infamous old person smell was gone within an hour or two, and the air simply felt lighter. Its rather remarkable.

Original part works great.
