Love this air purifier! Only reason why i gave 4 stars is due to the air freshner. You can not smell it at all

Stays 0%. I cleaned everything, filters and youtube how to fix it the 0%. But nothing. Its just a regular blowing fan right now. Watse of money. Cant even return it to bestbuy. If anyone can help me fix it pls let me know.

It's not worth $300, there are no observable physical changes to the air quality, it just adds to the electricity bill, severely overpriced, I wish I could get my money back

i just went to pick this air purifier from best buy and its never left 100%. No mater what room i put it it says 100 all the time. Which is weird , as all videos I see online, their air quality hardly ever starts and stays at 100% clean air al the time. yes I removed the filter from the plastic bags well i bought this purifier from Bestbuy today should i return it? Is their a way to reset the machine or the sensor??

Unboxing and Setup The unboxing and setup of the Shark NeverChange air purifier was simple. The included Quick Start Guide has clear instructions and illustrations for setting up the unit for use. Removing the packaging around the unit, tape on the fan vents, and the internal filter was simple. I unpacked the included order neutralizer and followed the instructions for inserting it into the top. I placed the unit on one of our side tables in our living room about a foot from the primary window, plugged it in, and pressed the power button. The unit has easy-to-understand controls and displays on the top and an air quality display on the front. The unit immediately tested the air quality and automatically adjusted the fan speed. The initial reading of our air quality was 85%, and within an hour, it was up to 99%. Usage Usually, I don't need to use the air purifier since the quality in my home is 98-100%. However, in the past few years, we have had smoke from summer fires, and I expect we are due for another season of smoke. So far, the only extensive test has been when we are cooking. The air quality can drop to around 85%, and the unit does an excellent job bringing it back to 99% within an hour. I always leave the unit running since we have two cats and a large living room. The air is noticeably cleaner and smells fresher. I'm impressed with how quiet the unit is in automatic mode. It is noisier but tolerable if I force the fan up to full speed. Due to the shape and look of the air purifier, my wife says it should come with robotic arms and move around the house on its own. Features • Touchscreen controls and a clear display on the top of the unit. • Touch controls for air cleaning mode, display light intensity, particulates info, fan settings, time till the air is clean, and lock to prevent accidental control selection. • Air quality display on the front of the unit. • It can clean the air for multiple rooms up to 1400 square feet. • Airflow is through an anti-allergen NanoSeal HEPA filter. • Two DebrisDefense easy-to-clean filter screens for trapping hair, dust, and lint, protecting the HEPA filter for a longer five-year life before replacing it. When the ring on the front display pulses, it is time to clean the side filter screens, which easily lift up and out on each side. • 99.98% of dander, dust, odors, smoke, pollen, allergens, irritants, and pet hair are filtered out, thanks to the medium particle, activated carbon, and NanoSeal HEPA filter layers. Per IEST-RP-CC007.3 99.98% @.1-.2 microns. • Auto purify mode (Clean Sense IQ) will monitor the air quality and adjust the airflow accordingly. • Includes an Odor Neutralizer cartridge with three settings to guard against odors and release a fresh scent. • The replaceable air filter is suitable for up to five years with regular cleaning of the DebrisDefense filter screens. • The display can show air quality and the amount of particulate matter in the air in increments of particulates per million at 1.0 microns, 2.5 microns, and 10 microns. • In Auto Mode, if 100% clean air is achieved for five minutes, the unit will enter Eco Mode to optimize the HEPA filter life. Summary We are delighted with our Shark NeverChange Air Purifier. Undoubtedly, we will be healthier and safer during fire and pollen seasons, and there will be a lot less cat dander floating through our air.

I bought this after having a full on sneeze day recently. It was horrible. I don’t think that will ever happen again with this unit. It makes the air more comfortable to breathe, and I like how it circulates the air in the room. I’ve got two cats and I don’t smell them any more. I also smoke and don’t see the smoke lingering in the air anymore. This is a game changer and a life saver. I love my shark vacuum and how well it’s performed under heavy use throughout the years, so I’m looking forward to this unit also working well.

My air purifier for my front room needed a new filter. I ordered a replacement filter but despite the filter being the official filter, the air purifier wouldn’t work as it did before. That left me with a fancy-looking fan. It was time to replace that old, useless air filter with the Shark NeverChange Air Purifier. And I am really liking it! Set-Up: There’s no complicated setup process for the Shark NeverChange. Remove the device from its box, remove the plastic around the filter, and plug it in. It’s worth mentioning that this purifier is beefy in size but has a futuristic minimalist look to it. You don’t even need an app to operate it. Just select the mode you want (mine is on Auto) and you’re good. The Clean Air display is well-illuminated, allowing you to see the air quality in the area. Performance: The Shark NeverChange fan is quiet. I don’t even notice it’s on until there’s a change in the air quality. Speaking of air quality, the Shark NeverChange detects when there are ‘hazards’ in the air. There was a grass fire miles away that created a lingering smokey haze in my area. I got home and brought in some of that air, causing the Shark to go to work. Its fan power increased and the Clean Air display went from 99% to 70% pretty fast. It was only when the fans were at full power that I could hear the Shark NeverChange. As a bonus there’s a Odor cartridge included that freshens the air like a fabric softener. Maintenance: That’s the beauty of this air purifier, I technically won’t have to change the filter for five years! That’s at least a couple of years of filter replacement money saved in itself. If you’re thinking about getting an air purifier then I would suggest that this be your first. Air purifiers also reduce the amount of pet dander and dust that normally accumulates day to day. There are so many benefits to them. And if you’re looking to replace an air purifier then how could you go wrong with one that doesn’t need a new filter for a few years?

Let me get right at why you might read this review. I have had a few weeks using this new Shark NeverChange Air Purifier Max and it is terrific. Its only possible shortcoming, as with any air cleaner/purifier that I have ever had, would be noise of the fan. But lets be real, without the fan spinning at higher levels it will never clean enough of the air in your home or office to be any use. And YES, this definitely is cleaning the air in my home. And it does it all on a set it and forget it "auto" mode. The terrific sensors built into the purifier ACTUALLY takes care of the air for you. Especially useful around dinner time. Most evenings it ramps up as the LCD score on the front of the unit goes down. We are not burning dinner, but it senses particles in the air and it ramps up to suck those particles out of the air. Within about an hour. It has mellowed to a slower/calmer fan speed and the house is as if we had cooked nothing at all, smelly foods or not. Just be aware of where you locate the unit. We placed ours at the edge of the living room in the traffic flow between kitchen and bedrooms. While it may look like R2-D2 and a 20lb propane bottle had a baby. It can get loud like an old school window air conditioner on max/high and it can last for awhile as it freshens and cleans the air. The included odor neutralizer seems to work without adding a masking scent to the air. The neutralizer has a smell to it, but its not identifiable to my wife or me. Its just a pleasant clean smell. While I have only ever owned 3 big house air cleaners. This Shark is by far the best performer, and it is actually sensing the need to clean dirty air and ramping up the fan to work harder at cleaning the air. You can also see particulate info on the LCD display. My older highly rated air cleaner never ramped up to clean the air like this shark does. The Shark is also significantly louder at all but the lowest speed. A bit like the hum of a refrigerator when it cycles. So, If a fridge hum is annoying to you. You might want to place it out of the way. Yet, despite the slightly increased noise. This machine WILL clean odors out of the air. And with the promise of possibly up to 5 years before the air filter replacement. Just keeping the air scent pod changed and the prefilters clean on either side could make Shark NeverChange Max the best air purifier from any brand.

The Shark NeverChange Max is compact but effective. I measured it a height of 22.5 inches and a width of 11 inches. It sits conveniently out of the way and doesn’t require much space. At lowest fan speeds in eco mode, this Shark is also one of the quietest air purifiers I’ve owned. I sometimes check to verify it is still on and running at night because it’s so quiet. It’s noticeably louder at higher fan speeds, but most times it is unobtrusively quiet. The fan can be manually be set to the lowest speed if it speeds up in auto mode and interferes with sleep or other quiet times. The same applies to the lights and audible tones for the touchpad. Both can be switched off from the touchpad if they become disruptive. Overall air quality is normally displayed by default. Touching the info button switches the front display to PM level and cycles through PM 1.0, 2.5, and 10. Like my other air purifiers, VOC and CO2 levels aren’t displayed on the device, although it does filter VOCs. The top mounted touchpad has controls for airflow, fan speed, auto/manual modes, dust filter status display, power, timer, and a child lock to prevent unwanted changes. The true HEPA filter cleans allergens such as dust, mold, dander, and other particulates. It also filters smoke and VOCs thanks to the activated carbon in the HEPA filter. In addition to the internal filter, the purifier has two removable mesh screen filters that slide over the air intakes to filter out larger dust and debris. Whenever air quality drops, the fan speeds up, the displayed air quality drops, and the light circle around the display changes color based on existing air quality. Blue is good, yellow is fair, and red is poor. The Shark does a good job on airborne allergens based on my symptoms. However, during the first day of use it constantly displayed air quality as 100% and all three PM values as zero. This was despite a stand alone air quality meter in the same room indicating poor air quality and a PM 2.5 level of 3 and another nearby purifier indicating a PM 2.5 level of 2. The poor air quality was mostly caused by high VOC and CO2 levels at the time. By the second day I finally started seeing changes in the displayed air quality on the Shark. The light ring around the display began occasionally changing from blue to either yellow or red depending on air quality, and fan speeds increased accordingly. The Shark is a lot more active now, and PM readings are more consistent between the it and another nearby air purifier. The included odor neutralizing module screws into the top of the device and does a good job of eliminating stale or musty smelling air and odors. The module has four adjustable intensity settings for the mild fresh scent it produces. The scent was most noticeable the first day but barely detectable by the second day. Despite the absence of fragrance, the room remains fresh smelling several days later. I believe the scent didn’t last long because I left the module set at maximum intensity. The user guide recommends setting the fragrance intensity to off whenever it is not needed. This helps prolong the effectiveness of the fragrance. There is no companion app available for the Shark. I searched the app store for my device but the only Shark app available, is for Shark floor cleaning robots. I also tried scanning the QR code sticker on the device but it only links to the product page and user manual. I operate and monitor all functions using the top mounted touchpad and the digital display on the front. There is an optional physical remote available for purchase if desired. My allergy symptoms have remained mild since switching to the Shark purifier in this room. Severe allergies are the primary reason why I use air purifiers and air quality meters throughout the house. If inside allergens are left unchecked, I experience everything from itching burning eyes to severe hives. So far, I have remained mostly symptom free in while using the Shark purifier in my bedroom. No purifier has proven capable of completely alleviating all my symptoms. Like our other purifiers, the Shark provides enough relief to keep symptoms mild and manageable. The Shark doesn’t have as many bells and whistles as our other two purifiers, but the only thing I honestly care about is effectiveness. I typically keep all of the purifiers on auto, and forget about them anyhow until it’s time for maintenance. I use my stand alone meters to monitor air quality because they provide much more comprehensive data for both indoor and outdoor air quality. All three air purifiers, including the Shark, are usually good at quickly responding automatically to sudden pollutant spikes. The five-year filter is a welcomed feature in this era of skyrocketing inflation. It does state “up to five years”, so it can possibly require earlier replacement in heavier use scenarios. I hope it actually does last and remain effective for the full five years. Occasional maintenance consisting of cleaning the filter every couple months with a clean microfiber cloth or vacuum is suggested to help prolong filter life. The same goes for the two external mesh screens. The internal filter cannot get wet, but the two mesh filters can be rinsed clean with plain water if heavily soiled. No cleaning chemicals should ever be used on either the internal or external filters according to the user guide. The Shark automatically alerts on the display when the mesh filters need cleaning. Filter status can also be displayed manually using the filter info button on the touchpad. The machine frequently goes into eco mode, which is the lowest fan speed, whenever air quality is at 100%. This helps preserve the life of the internal filter and components. The only other housekeeping task, other than occasionally replacing the odor neutralizing module, is a quick wipe down of the exterior.

Never change? Can it be true? I’m excited by the idea that this filter will last 10 times longer than a standard air purifier filter. I can see what may actually make that possible too! It has two pretty cool slides on the side of the machine that can come out and be rinsed or washed as needed. I can tell you it works too! Kids fiddled with my toaster controls and I didn’t notice when I made my toast. Was quite burnt! The air purifier could sense the smoke and was working hard to clear the air. The light up blue circle turned red and you could hear the fan filtering the air, but it wasn’t too loud! Was a very acceptable amount of noise to be going full blast. I love the sleek design of this air purifier. My young nieces were fascinated by the looks and asked what it was as soon as they saw it. We all agreed it looks like a robot! I have this set up in my open space downstairs and it’s doing a great job. We have wildfires and the smoke is really bad outside but inside we are doing well & not able to even smell it. It also has this cool odor neutralizer that has a light fresh scent. I can definitely see myself using that and replacing it when needed. It has an adjustable scent control as well. Shark air purifiers are great. This is my second one and I’m happy with its size, performance & design. If you’re in the market for an air purifier I would recommend this one.

The Shark Never Change Air Purifier Max is a good buy. It comes with a 2 year limited warranty. It is modern looking and super light weight *moving it to a new location is quick and easy. The purifier comes well packaged with detailed startup instructions. The complete set of instructions must be downloaded, but the quick start guide will get you going immediately. I do recommend downloading the instructions to see the complete guide. It was there that I found better details about the maintenance. I love that they recommend vacuuming the HEPA filter and prefilter every 2 months. I have other purifiers, and I do the same thing, but the manufacturer does not specify it. They would rather charge you for a new filter instead of increasing the lifespan with routine maintenance. This unit even goes so far as to flash you a message on the air quality screen when the maintenance needs to be done.       I could immediately smell the difference in freshness right when I turned on the air purifier. Air purifies that are effective have a nice charcoal filter smell to them. This one had it right away. Regarding the odor neutralizer, after about a week I got the courage to try it. I was pleasantly surprised since I am very sensitive to overpowering air fresheners and perfumes in general. The dial lets you select the strength of the scent. It is not overpowering, even on the highest setting. The odor neutralizer will last about 3 months according the manual. The replacements come in a 2pk on the website. They also offer an optional remote control on the product accessory website. The air quality indicator is a very nice touch. It gives you piece of mind about the size and amount of particulates floating around in your air. 1400 sq ft of coverage is pretty amazing. My open floor plan living space utilizes it perfectly. I have also moved it into the bedroom and found that the sound of the purifier gives me a better quality of sleep and helps me to fall asleep faster. The quality of air also contributes to the sleep quality too. I have noticed less dust as well. The great part about having it in the room while sleeping is that the display can be darkened and only the power button and dimmer button are dimly lit. This is perfect. I can't tell you how much I appreciate this. I have a different purifier that does not dim and therefore has a random instruction booklet taped to the top to cover up the lights. No such problems with this purifier. On this unit, there is a timer option which is very handy. I am considering a second unit for my upstairs area because I am so pleased with this one.

I’ve tried a variety of air purifiers through the years, and some of them work pretty well while others, not so much. When the pandemic hit and wildfire smoke also became more common, having these in your home went from a novelty, to more of a necessity. That, and I live in a very high pollen area that can cause my sinuses to go crazy even indoors at certain times of the year. So the Shark Neverchange Max hits stores, and it’s a little different than most other purifiers. The Neverchange has a filter that Shark estimates can last up to 5 YEARS in-between changes when used moderately, and this particular model can handle up to 1400 square feet if placed in a more open area. It’s a pretty good looking machine – they come in silver (more white) or black – and is moderately sized but not a monster, at just under 23 inches tall by just over 13 inches wide. Setup is quick – you just remove any plastics from the filter, put in an odor control cartridge (included) if you want, and place it on a floor at least 3 inches from any walls or objects. Took me less than 10 minutes after unpacking it to getting it running. The filter has varied states that start off by a basic dust filter, clearing basic air debris (which you can wipe off when needed), passing through a pet filter layer, a carbon layer, and finally a “Nanoseal HEPA” layer that can capture particles in your air as small as 0.1 to 0.2 microns. Side note – the first basic filter can be pulled out in two parts from both sides of the machine to wipe off (they look like machine handles but lift the filter out instead – the carrying handle is on the back). Air is pulled in through the sides, and clean air is blown up through the top. A digital readout on the front lets you know how dirty or clean your air is in percentages, and if put in auto mode, will ramp up or down the fan to clean more or less depending on what it senses. It will also let you know when it’s time to eventually change a filter or clean the dust filter. Or, you can simply set it manually for varied stages from low to very high depending on your needs. It’s very quiet in lower settings and once you crank it up you can definitely hear it, but it’s more like an air conditioning noise rather than anything obnoxious. You can set it to run for a certain number of hours and then auto shut off, too. Odor control cartridges can be inserted into the top (mine came with one) but I wasn’t crazy about the scent so have decided not to use it in mine. The power cord is 6ft which is pretty good, but I always like to see max lengths for items like this for the best placement in a room. My one complaint: There are QR codes on the setup guide and machine that allegedly take you to their web page for that machine, but in reality it just takes you to Shark’s generic sales page and after digging a lot I still couldn’t find what I was looking for. I didn’t need more ino as again, setup is very easy, but the QR really should take you directly to the product model number’s page in my opinion. Since I haven’t had the Neverchange for that long, I can’t rate the validity of it lasting up to 5 years, but I can say that it does make a big difference in the air quality in a large room compared to others I’ve tried. I have an air quality monitor that goes off from time to time regarding dust or other things in the air, and since turning on the Shark Neverchange, those alerts have gone way down, so it’s working. I would say that while it's a little pricey compared to some, this is a worthy investment to improve the air quality in your home or apartment considering the levels of dirt, dust, dander, and germ cooties that is typically inside these days, and by how much square footage it will clean out compared to smaller units on the market (provided the filter does last at least 3-5 years - time will tell). Thumbs-up!

Gobble up the bad odors, dust, and pollen with this. Luckily I am able to put this within a few feet of the HVAC register and I think that helps even more. Auto mode is very responsive, sometimes too much, but it is very quick to clear out any bad air. Turned it off for a few days when moving decor around for Christmas and soon noticed the air quality was worse without it. Cannot live without this now.

I was excited to try this out since indoor air quality is very important in our household. Especially with airborne allergies, we suffer quite a lot from allergies. For some context, we are 2 adults, a Labrador retriever that has free reign to go in and out as he pleases, about 1000sq ft in the 1st floor, some carpet. Unboxing this thing was easy enough. It is a large box and within it is the biggest air purifier I've had my hands on. It doesn't really go with our home decor and it will stick out with its size and look. With its big size comes big performance. It claims to cover up to 1400sq ft and it does it well. It's included odor neutralizer gives our first floor a pleasant fresh smell. The biggest selling point for me is the fact that I can turn this on and not have to worry about buying air filters as often as I am used to. Your mileage may vary depending on the size of your area and how often you run the air filter. I just like having a device with less maintenance involved as I use it. In auto mode, it does a great job with running the motor that best optimizes for the air quality. At the increased fan speed, it is noticeably audible but again you trade off with getting good air quality. A big digital gauge on the front gives a clear indicator as to your quality. The top display calls out the options for fan speeds, on/off switch, screen dim for night mode and a lock function.

The Shark NeverChange Air Purifier MAX is a powerful and efficient air purifier. It effectively removes dust, allergens, and odors, thanks to its multi-stage filtration system. The standout feature is the NeverChange filter, which doesn’t need to be replaced, saving time and money. It’s quiet in operation and has a sleek, modern design that fits well in most rooms. Overall, it’s an excellent choice for improving air quality with minimal maintenance.

Best purifier ever!! Love that the filter lasts 5 years, love the improvement is air quality in our home, and appreciate how quiet it is. Bought 3 of the smaller version for the bedrooms because I loved this one so much.

Works well and super quiet. I like the fact you are not always changing filters. This air purifier is easy to use and clean.

A Bit on the pricey side but not having to replace the filter for upwards of 5 years may be worth it. The room scent thing that comes with it doesn’t last very long and are a bit pricey to replace (even off brand ones). The auto feature is great but wish it had a timer on and off with the auto. It seems to use auto more when cooking in the house as it likely detects the heat. Nothing dramatic in our home change but potentially more air particles are gone.

I am a fan of the shark air purifiers. I have one of the larger units that purifies up to 1400 ft.². I was very interested in one that you don’t have to change the filters out except for every five years. The set up is very simple. There is a twist to the bottom to remove the filter and little tags that hang on the filter to make it easier to pull out no matter what end you put it in. The part that you clean as needed is mesh filters on the outside of the unit . There are two one on each side the set up is the same as my other purifier where you can set it up at different speeds or put it on auto where it detects when more is needed. Mine was purchased for the basement so it is on max Right now until it clears the air and then it will adjust itself. If it’s anything like my old one, even someone sitting around vaping will make the purifier ramp up to eliminate what it detects in the air. I saw that in action for myself, and will never , go without one of these units in my home. Which is why the deal they had on this one was worth me purchasing it for my basement to have it on both levels of my home to clean the air. My son has very bad allergies, and I have noticed the difference in his symptoms with the purchase of the first unit. I can only assume that it will improve with a second unit on the lower level. Definitely worth the purchase and even more so with the sale price.

By far my favorite purchase this year! It works amazing in my home. Makes the air feel very clean and the device itself does not take up much space. Unlike other air purifiers you do not have to change the filter for a while with this one and with a new baby it is worth the money spent!
