The actual Guardian filters make such a huge difference in the Guardian Air Purifier machines! I had spent some time trying a few of the knock-off brands that germguardianoutlet.com sells and then came back to the real Guardian ones again and WOW are they ever making a difference. The machine is running silently, we are back to breathing easily even though we are in the high pollen season and there is far less dust in the house. I will stick with the real thing forever now, it is definitely worth the extra bucks for your health.

Is not bad stuff .. the one thing I’m not happy . Have said cook and warm mist.. there’s no warm must and box package was torn half when I got .it seems it was returned from other clients. I have no time to return so still using it with cool mist setting only

I live in the central valley in California one of the biggest ag in the USA. Right now it's almond season and fire season. I also have 2 dogs. I got this for my bedroom and my 4 year old has bad allergies takes prescription and natural supplements. It's easy to install you place it in and slide to lock and unlock. It's not too noisy I sleep with a fan on and it quieter than that. It does have a little smell at first but not bad. It traps hair and dust very well. I subscribed to recieve them in the future.

I really liked this, easy to fill, quiet.

I cannot read the screen on this when the air quality screen goes yellow which it is all the time in my livingroom. Even in a partially dark room, it's impossible to read.
I'm also questioning the accuracy of the reading as it seems to fluctuate a lot for no apparent reason I can figure out. Not sure if this is something going on in my living room or if the monitor is working.
I would like to return it but it's past the return window.
