[This review was collected as part of a promotion.] I've had air purifiers in the past but this has been the best one I've ever used. I keep it between our kitchen and living room. Anytime I have an odor in the kitchen, it works so well at making the odor gone fast!! I love that it shows the percentage of how clean your air is. I keep it on auto because that is more energy efficient. The max is very loud so you wouldn't want it on that all the time. It is large but that isn't an issue with me. I love that you don't have to constantly change the filters. I highly recommend this air purifier!!

[This review was collected as part of a promotion.] I bought this about a month ago because, My family suffers from indoor allergies as well as pet allergies. When it is shedding time everyone struggles. However this Shark air purifier makes the air clean and fresh so we can breathe easy once more. I really like the look of it, it fits nicely with any home decor. The touch top and controller can be used separately or only one. When fire season kicked up smoke in the air the indicator let us know how bad it is as it cleans. I like being able to see it change slowly until it reads 100% clean. Also, has an air freshener which is optional if you want to use it or not… i would definitely recommend. This has helped everyone tremendously. Allergy season has stopped bothering us for the most part when inside. It is super easy to use and works amazing. I am impressed with the quality and will be purchasing another for the downstairs. The air is clean and everyone in the house feels better.

[This review was collected as part of a promotion.] I really enjoy this air purifier. I had been looking for one, for awhile, and it just so happened that I was able to get into this Influenster! I really love how clean the air seems! I have 3 cats and it is very hard to feel like everything is clean, when you have cat fluff floating around. The system is pretty sensitive, but in a good way! I also have a humidifier in my room that I need to use, due to bad allergies. Anytime I have them both on at the same time, my Shark air purifier air quality percentage tanks! Of course this is on the nose when it comes to how a purifier works. The only caveat that I have with the air purifier is that when you go to adjust the filter on the bottom of the machine, you turn it to lock it in place, but if you put it on a surface and turn it at all, it will unlock you filter, so just be careful!

[This review was collected as part of a promotion.] The Shark Never Change Air Purifier Max is a great addition to my bedroom. The air circulation in my room is great, and it smells really good with the odor neutralizer cartridge. You can purchase replacements. I LOVE that the motor is whisper silent. It won't affect my sleep. It reads the air quality levels in your room. I am so happy to have this. I am going to recommend it to a family member who has allergies. I have used it for a while before I did this review to give an accurate assessment of this system.

[This review was collected as part of a promotion.] I cannot believe we went years without one of these - the results are INSTANT. We live in the midwest. Basically a RED ZONE for all things related to air quality, pollen, pollution, etc. We also have dog, birds, cats. During the mornings, we like to open our windows to let some fresh air in but we also get the pollen. For years, I've had to have an inhaler as it affected my lungs. We tried the Shark NeverChange Air Purifier and what a wonderful piece of modern technology. Out of the box, it was ready to plug in. You also get the odor neutralizer (we have a home gym and that room gets rather muggy and smelly). We love the look, design, functionality, and the SILENCE of this thing. Even when it's fully powered. There's no distractions or attention drawn. It's beautifully sitting there in the corner doing serious work. I love the digital reader that shows you what your air quality is. We noticed how low our score would get after making breakfast, cutting the grass, or even running the vacuum cleaner. Rather than that air simply circulating with your ceiling fans, this purifier is recycling the air and you can feel the magic. The first night we ran this and then walked downstairs, it felt like a brand new atmosphere we were in due to the amazing air quality and smell. I haven't used my inhaler as I have had no breathing issues after we received this. That 'home smell' every home has is no longer present as the odor neutralizer makes your home / air smell quite amazing. I no longer have to apologize to my guests as we walk past the gym room as it normally smells just like a gym bag but it smells pleasant! This is a MUST HAVE piece of technology for anyone. Homes need these and your quality of life will appreciate you for it. We cannot recommend this enough!

This air purifier has been wonderful. It runs very quietly in the background. The odor technology is great. We have 4 dogs in the house and when you walk in from outside, the house smells fresh and clean! I would highly recommend this product, especially for pet owners!

[This review was collected as part of a promotion.] I am OBSESSED with this air purifier. First, the display is easy to read, and color coded to match the air quality in the room. It makes it so clear to know whether air quality is suffering or not. It looks great in the room, taking up little space. It does not run when the air quality is good, saving energy. Plus, the filters don't need to be changed often which is hugely helpful! When it is running, it's super quiet.

I bought this a few weeks ago, and I was hopeful it would do everything the description said it would.  My wife and I built a new home, and it is so dusty.  She says she can dust one day, and the next day, everything is covered in dust again.  This was really bad in our bedroom because our furniture is dark.  After a thorough cleaning of the room, my wife tells me there isn't any dust, even after five days.  She is thrilled.  We do have the unit set up in the bedroom and have it at full speed during the day.  We are going to move it into the living room to see what happens then.  I will probably buy the smaller unit for that bedroom as no other room seems to get as dusty.

[This review was collected as part of a promotion.] The SHARK " Never Change Air Purifier Max" (Model: HP302) with adjustable odor neutralizer technology, 4-layers of filtration system (high performance nanoseal HEPA, activated carbon, medium particle and debris defense) efficiently self adjusts its fan speed based on the air's pollution level while still running insanely quiet. Furthermore, the unit did an excellent job clearing the air while doing frying - not only in the kitchen area but also the adjacent dining room, responding in real-time and automatically reacting to prodigiously purify pollutants and odors in minutes. Bottom line, the stunningly aesthetic Shark Never Change Air Purifier Max does a phenomenal purification of indoor pollutants and odors.

[This review was collected as part of a promotion.] This shark air purifier. Max is amazing quality. We suffer bad allergies and we are always sick but ever since I've had this the air in the house feels really cleanse we're not sneezing as much and our allergies has been really good I even tested by lighting a scented candle right next to it, and it will trigger the machine to Work when I put it on auto, it will start cleaning the air and the percentages drop and I'll tell you how much time it needs to clean and purify the air.  it detect any allergies at any size and it will pick up and you can hear the machine start working blowing out air really cleaning it and the style looks very nice. It is a little bit on the bulky and big side so I do try to use it like behind the couch.
