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.
I would recommend this to a friend!

Exactly what I expected.

It works as intended. I'm using it in my master bedroom suite. I like that the remote control from my previous shark he401 works with it. I'm not sure what the other reviewers are expecting it to do. The only issue I have, is the sensor on this model and my previous he401 model react to my humidifier in the winter.

I did not think this was going to be as good as it turned out! The air quality in my house is GREAT! Just set it on AUTO and it cleans the air as needed. I even noticed better sleep and not waking up in the morning all stuffed up. This is a great unit, I purchased one for up stairs and down stairs. VERY IMPRESSED!

Pricey, but very useful

We have had this model for several months. The volume of pet hair and dirt it catches is staggering. We just purchased another for another room and a smaller one for the bedroom. Very satisfied.

Feel the same as Aussmom below.

Just as Aussmom said... there is no pet hair and my house remains dusty. I have 2 that cover 1400 in a 1400 sq ft house. The furniture within reach of the unit has a dust layer. The air indicator only changes when I cook. Im running 24/7, check the screens often. The neutralizer is done already. Haven't had them a month yet. I was hoping to walk into a house with less odor and dust.
No, I would not recommend this to a friend.

Hi there,
Thank you so much for sharing your experience — we’re truly saddened to hear that things haven’t gone as expected. We understand how important clean air and a dust-free home are, especially with pets, and we appreciate the care you’ve taken in running your units continuously and checking the filters regularly.
If the air quality indicator only reacts during cooking and you're still noticing dust and odors, it may suggest the units aren’t circulating air effectively throughout your space. We’d love the opportunity to troubleshoot this with you and make sure your purifiers are performing at their best.
Please reach out to our support team at 1-855-427-5127, and mention this review so we can prioritize your case. We’re here to help and committed to making this right.
Thank you again for your feedback — it helps us improve and serve you better.

Don't buy this one.

I have the large size in my living room. It picks up all the cooking smells and cleans them away. No issues. I have the smaller one in the room with my litter boxes. It does absolutely nothing. Says the air is 100% all the time. The room is no bigger than a closet. I had it in my master bedroom first and it did nothing for the dust. Smaller one needs work.

Hi there,
Thank you for your honest feedback and for using both sizes of our NeverChange™ air purifiers. We're glad to hear the larger unit is working well in your living room and helping with cooking odors — that’s exactly what it’s designed to do!
We’re sorry to hear the smaller unit isn’t meeting expectations in your litter box room or master bedroom. If the air quality reading consistently shows 100%, it may be due to the sensor not detecting particles at its current placement or limited airflow in the space. We understand that doesn’t reflect your experience, and we’d love to help troubleshoot.
Please reach out to our Customer Care team at 1-855-427-5127 so we can look into this further and ensure your purifier is working as intended. We truly appreciate your feedback — it helps us improve.

Love it so much. I can see such a difference. We don’t have a vent in our kitchen and our house doesn’t smell like whatever we cooked the night before anymore
