Got this to replace our old filter. Fits and works well!

This is the only filter for my Germ Guardian HEPA GENUINE Air Purifier. My local Target store never can keep a steady stock. Therefore, I thought of Amazon for my needs. The prize is perfect and better than what Target offer. Thank you Amazon for having this filter in stock. My allergy says, thank you.

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.

Works as it should. Easy to replace.

I love these filters. Solidly made, has some free installation, comes as 1 piece and does a great job. Also, these are longer lasting. Pricey but the quality is un-matched. Highly recommended

Pricey but will purchase again.

So super easy to change filter. Love it. Will buy again

Last year, I threw away my Honeywell Air Genius 5. As much as I liked it, it was frustrating to maintain and it had a mind of its own. I trust Peer Guardian products. Ive had numerous humidifiers made by them so I bought the Germ Guardian AC 4825 to replace the Air Genius. Out of nowhere, about 6 months after buying it, it started flashing a red light to change the filter. Air Genius had a permanent filter. But dont fooled by the permanent filters, its one of the reasons I got away from the Air Genius, the filter wouldnt clean properly. So, I knew the Germ Guardian had to have replacement filters but I hadnt bought any. I bought one of the generic versions here from Amazon and its good but when I turn my purifier on, I love the fresh smell, its probably not even noticeable to most people. The generic replacement filter never gave me the fresh air smell but it was doing a good job on everything else and at the time it was eighteen dollars less than the name brand, about a sixty percent difference in price. I need that fresh smell. I have a puppy that stays in my office and hes a little guy and he stinks. He cant help it. I give him baths but I think its because hes so short, his belly hits the ground. Im picking on the puppy. He has hair that sheds and sucks up any moisture so he dont really stink but he has his own unique smell. The name brand filters help with that and give me a more fresh smell in my office. This upgraded version is a perfect fit and it comes with an attached carbon prefilter. It goes right in, no problems and it brought the fresh air back. Simple, easy, change and I caught these on what I assume was a sale for right at twenty dollars, so I bought 2 of them. They are usually around thirty. I also recommend this purifier even over the bigger version and the other brands. I run it on the medium speed from the time I walk into the office until I leave the office. Its like flipping a light switch on. The room its in is roughly 15 x 17 and it also keeps the air fresh in the 8 x 10 bathroom thats connected to the office. Not the funnest present to buy yourself but if youre like me, your nose and sinuses and stinky puppy will thank you!

Great quality and perfect size!

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.
