Ours lasted about 2 years before it just stopped one day abd the screen showed to dash marks I assumed it meant the main filter had finally given out. Now we ran this thing hard daily 24/7 so a little over 2 years is acceptable in my opinion plus we have multiple long hair dogs, long hair cat, etc. This thing is an absolute work horse! Only reason not 5 stars is cannot find official replacement filter anywhere so cannot use without it!

This one catches more pet hair than the one I had before. I’ve had the blue ring(100% good air) since I set it up.

The unit says my air quality is 100% when I know it is dusty and not clean! It almost just measures smoke or chemicals and not dust particles.

Very pleased with Shark Neverchange Air Purifier. Easy set up and use. I noticed an air quality difference witin a few hours. Perfect for my home, good value, and would recommend.

Absolutely perfect air purifier! I love how easy to clean this product is. Performs great as we have a dog and keep our air feeling fresh. Great value for product and easy to set up

I do not know what to expect when it mentions it will purify the air I still feel the same so there needs to be more input on what exactly it will do clean my air for better breathing. I am still in a very early stage of using the item.

I have been using the shark NeverChange Air Purifier Max in my living room and I am very impressed with its performance. The setup was quick and easy, and it started working right away. One of my favorite features is the air quality display, which provides real-time updates and helps me monitor the air in my home. It runs veri quietly, even when operating for long periods making it perfect for everyday use. The design is modern and looks great in my living space. I also appreciate the NeverChange filtration system because it reduces the need for frequent filters replacements. Since I use this purifier, the air feels fresh and cleaner. I would highly recommend to anyone looking to improve indoor air quality.

I cooked onions garlic and peppers with the air purifier on. Hour later still smells like I cooked my dinner. Smell is not as pronounced but for the square foot it's supposed to clean and my home is less than that. I'm kinda disappointed in shark as they have always made great products in the past. What's is happening in the manufacturing end?

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.

Do not fall for their "NeverChange" filter that supposedly lasts about 3-5 years. Not even close! Mine lasts about 6 months, and that is in par with most reviewers are also experiencing. The filters are expensive and in reality this Air Purifier feels more like a filter subscription that you didn't intend to sign up for. False adverstising and misleading marketing strategy.
