Tremendously disappointed

This is the second I have received. The first purchase didn’t work properly, you sent a replacement that also doesn’t work just like tge first. Looks like now you’re trying to trick me into buying another? A newer version? I want what I already purchased yo work properly, is that too much to ask?

Not as expected
on July 13, 2026
Posted by: Sam1223
I’m disappointed with the Shark NeverChange Air Purifier. I expected it to collect much more dust, but after using it for a while, it doesn’t seem to capture nearly as much as advertised. there’s plenty of dust in my home did not feel any difference with purifier.
I’ve used a few generic air purifiers that actually seemed to do a better job at trapping dust and improving air quality. Based on my experience, this product hasn’t lived up to my expectations, especially considering the price.

From day one my allergies changed —
on July 4, 2026
Posted by: Lilischarm
from Miami, Fl
Gender:Female
I didn’t expect to notice a difference so fast, but the Shark NeverChange™ Air Purifier Max genuinely surprised me. From the first day of using it, the air in my space felt noticeably cleaner and lighter — and most importantly, my allergy symptoms improved way quicker than I anticipated.
I usually struggle with dust and seasonal irritation, especially indoors, but this has made my environment feel much more controlled and fresh. It runs quietly in the background, so it doesn’t interrupt my day or sleep, and I love that I don’t constantly have to think about maintenance or filters.
What stood out the most is consistency — it doesn’t feel like a “temporary clean air effect,” but more like a stable improvement in the room’s overall air quality.
If you deal with allergies or just want a noticeably fresher home environment, this one feels like a real upgrade rather than just another gadget
I would recommend this to a friend!

I ve been using it for several months now. It covers much more area than advertised. Efficient. Very quiet . Also the odor removing cartridge very useful and smart design. I use it as needed. Love the fact that filter goes up to 5 years.
I would recommend this to a friend!

Clean Your Air With Shark
on June 27, 2026
Posted by: JosieB
This is a compact size air purifier, that runs quiet most of the time unless air quality drops then it kicks up a bit, nothing too loud, has pull out reusable filters on both sides that catch dander, hair, dust… that are super easy to clean, a long lasting true hepa multi filter, and an adjustable odor neutralizer technology cartridge if you want scent. It is a little less than 10 lbs, has a 6 ft cord, and purifies up to 650 square feet in about an hour. It has a nice display that is easy to read that tells you what your air quality is along with adjustable levels or auto mode, and a lock mode to keep children from changing things. The air in our home is much cleaner since we got this machine.

Works like a well oiled machine.
on June 22, 2026
Posted by: JacobH
This thing really works well!! It is located in our living room which is near the kitchen. Every time we cook, you can see this thing get to work. It will drop down to around 50-60 percent air quality then boost the fan speed automatically until the quality is back at 100 percent. It fits into our decor well and isn’t too noticeable. The washable pre-filters greatly extend the internal filters lifespan.
