It seems to work well

We started noticing a difference in our stuffy sinus relief at about day 2. Would recommend

Not as I thought

Good at circulating air but not efficient with food smells from cooking

Well-worth the investment.

I've had this air purifier for a couple of days and inadvertently put it to the test. I have a wood stove in the same room as the purifier. I made a fire in the stove that didn't quite get going right away and I needed to open the door to shir the fire. Upon opening the stove door, smoke billowed into the room. The air quality dropped into the yellow zone with a reading of 73. The purifier went into immediate action and within about 15 minutes the air quality returned to the blue zone with a reading of 100. Aside from that, I also noticed that there is almost no dust settling on furniture that I usually had to dust daily even though I had an Alene purifier sitting right next to the furniture. IMO, this air purifier is well-worth the investment. My only beef is that it doesn't come in black.

WASTE of Money

I am so incredibly disappointed with this purchase. I spent a lot of money purchasing this item (air purifier Max) and two smaller ones for our home. We have three long hair doggies (border collie and Aussies) that leave a lot of hair and dander. It is a lot of work to keep the home clean and our allergies at bay. I was researching ways to keep the home cleaner and us healthier and everyone recommended air purifiers, so I went with a brand I trust. I also have two shark vacuums. There has been ZERO improvement in the quality of the air in our home. There has been no reduction in the amount of dust in the home. No reduction in the amount of pet hair in the home. I'm still having to do just as much manual cleaning now as I did before we purchased them. It always says 100% air quality unless we're cooking something particularly smelly then it does kick on for a bit. I purchased this at the end of June - so three months later and the filter says it's at 78% already. I know never change doesn't mean never - but I was hoping for more than a year out of it. I feel like this would indicate that there is SOMETHING being done, but I am not seeing it. I check the filters regularly and despite there being plenty of hair in the home (yes, even with vacuuming regularly) and there's just about none in the filter. I'm not sure what this purifier is even doing for us and I wish I could send them all back.
