If you like public bathroom spray,this is for you!

The smell of the odor neutralizer cartridge is disgusting. It literally smells like a public bathroom urinal cake. The fact that they don’t offer different scents is insane. I specifically purchased this for this feature so I’m returning it.
No, I would not recommend this to a friend.

Does not work!

Purchased 2. I originally placed one upstairs and one downstairs living area. However they both were reading at 60%. So I placed both downstairs which is approximately 1200sqft ( which one purifier should work for) opposite ends of the house. One in kitchen one in living room. One is constantly at 70% and the other 64%. It has not reached 100% one time in 24 hours. On auto mode running at max.
I don’t know if I got defective ones or what is going on but this is a giant waste of money. I have one small dog. I cooked bacon last night around 7pm and I can still smell the lingering smell so this purifier did absolutely nothing. And my allergies are still off the charts even with both units running on the same floor. I have auto immune diseases and immune compromised and so is my young son. Having purifiers that work is essential for our well being. I was enticed with the never change filter with hopes of saving some money on filter replacements of our previous purifiers.

Works out of the box

Works as advertised. I purchased 2 of the largest purifiers . One for the living room which connects to the kitchen. And one for the master bedroom. Easy to setup. Connected the one in the living room. 10 to 15 minutes it reached 100, while cooking dinner it dropped to 81. Recover back to 100 in about 25 minutes after done cooking. I always purchase Ninja products. May cost a little more than the other brands, but they just work.
I would recommend this to a friend!

Its OK for certain uses
on December 16, 2025
Posted by: John 1776
I got this a few weeks ago to help with issues we have with some smoke from our pellet stove on startup or if food gets over cooked to preclude the smoke alarms going off.. It seems to be ok but we still have a smell so it doesnt get all smells out of air.. Maybe it will work better with allergens or pet hair but for smoke smells of pretty much any type its not that great to us.We cant use automatic because it never speeds up enough to do any good. It always seems to show good air quality, so we have to use manual 95% of the time. So by using manual on higher speeds, we will have to replace the filter far sooner than claimed on videos or manuals. Be aware of that.

Very impressed!!!

Love it so much that I ordered another. It’s super quiet and I feel like it genuinely cleans the air. I like seeing the air quality reading on it at 100%. I know it works because we have ours set up near the kitchen and anytime we cook we notice the air quality reading drop some but soon after it gets right back up to 100%
