Customer Ratings & Reviews

Quiet, very effective, reacts fast to cooking cleaning oders, lights off mode, auto mode is great to use for long filter life. I use the higher price filters for maximum air cleaning.

Excellent! I purchased this because of my lung issues, it dies exactly as described. Soon as it's turn on it calibrated my room starting at 100% then within 30sec it went to 39%. I set it to auto, immediately the fan turned to high and started cleaning the air. It reached 100% in about 1min, so I tested it. My place is 600sqt so standing far away it was tested. It took about 10sec before air started filtering A+. I also have bad allergies but mostly it was brought solely to help with my lungs. And it does. This product is worth the purchase. And all that needs to be done is buy it to know it. This unit clean up to 1000sqt, if your room is over 600sqt. Get the larger size. It makes a difference getting the right one for the best cleaning.

Easy to remove the old filter and then put the new one in. Will be buying the replacement from Best Buy again.

Great at clearing the food oders from cooking quickly. Air feels fresh and helps with allergies.

I bought this earlier in the year after a family member got COVID and love it for many reasons. It’s quiet enough to forget it’s there and it automatically increases power when the air needs purification. For example when cooking. Also, have noticed a decrease in dust allergens.

Quiet and efficient. Works great. I use this in our church and it works great!

Love it! So easy to set up, not too loud and has made a big difference in our air quality of our home!

I love this air purifier. Shark nailed it with this unit. When the Shark Air Purifier 4 first arrived, it showed up in a discrete brown box covering the main product box in full color and graphics, detailing many of the options and features I was about to embark on, the box grabbed my attention, and I was now getting excited about finally receiving the air purifier. After opening the box, the air purifier slipped out with ease, beautifully packaged nice and tight with plastic to keep any contaminants out. Once the purifier was standing, it was amazingly simple to set up. To set up the air purifier, remove the back by pressing two tabs, remove the bag around the filter, replace the filter, put the rear cover back on, plug the unit in, and press power. That easy. After the power button is pressed, you can watch the purifier read the air quality and that is where the magic starts. This unit has amazed me since the day we turned it on. It is so efficient and fast, its incredible. The air has a different feel to it now, it just feels clean, and my allergies have substantially subsided since the first day we turned this machine on. I am incredibly pleased about how quiet this air purifier operates. We use it in auto mode and like that best, I have noticed it kicks on when we are cooking sometimes and obliterates any smells from the kitchen. My wife was cooking shrimp and within a few minutes, the smell was gone. The fans are amazingly strong and can handle a large room with ease. The fastest fan setting is the only real loud one, and still, it becomes a background noise that you do not even pay attention to. I would have no trouble sleeping if it were in my bedroom, especially in auto mode. The two lowest setting fan modes, you can barely hear at all. This unit has been so quiet it kind of disappears in the room but does serious work with the air quality. One of my favorite things about the air purifier is the ease of use. The main display has touch screen-like buttons that are easy to read and understand. Setup and changing the filter is a breeze, it is too easy and takes seconds. Another thing I really like is that you can dim the lights on the unit. I have small children that were messing with the pretty lights, but after you dim it down to nothing, they pay no attention. This is a fantastic feature if this unit is going in a bedroom. I found the real-time reading of the different air particles fascinating, and kind of scary that I have been living with those particles for a long time. The purifier quickly got rid of all those air particles and leaves behind this presence of clean air that cannot be described, but only experienced. Overall, I am pleased with the Shark Air Purifier 4, it looks amazing and sleek, its quiet operation, and ease of use you cannot go wrong picking one of these up. When I walk into the house from being outside or at work all day, you can feel the air and how clean it is, it is amazing.

his is my first Shark Air Purifier. You want an air cleaner that will deliver clean air at a high enough rate to clean your space several times an hour and at a high level of filtration if you want to control dust ( and the bacteria and mold riding on the dust). This means less cleaning and vacuuming too. I worked with air cleaners on my job, so I realized this was an exceptional one.

PROS: Aesthetics, thin design choice with back intake fans and side outtake fans, intuitiveness, onboard controls, remote, screen, overall noise, specs, ability to move and clean air. CONS: It beeps, which scares my dog because he is a wimp. AESTHETICS/BUILD/DESIGN: I have this unit inside of my room where I sleep. There are multiple things that I really like about it. The first being that it is compact compared to most other air purifiers. As it has more of a flat design instead of square with the intake being on the backside with fans going out on each side. Which makes it easier to “hide”. There are also handles on each side making it easy to move around due to the lightweight design. The power cord is on the bottom. Second, it has a very modern and sleek look to it. With what appears to be an OLED screen on the front and top. Both displays are very sharp, colors pop, with crisp lettering. The top display has ALL the information you need for the device which is a nice change of pace. Where most other AirPurifiers make you download an app if you want specifics, but with this guy it is all natively on the device. Which I like a lot. On the top left you have all the instructions you need for the device. Such as the four fan speeds (1. Quiet operation, 2. Reducing odors, 3. Reducing allergens, 4. Maximum cleaning). Along with switching the display to show Clean Air (how clean your air is from 0 – 100%), Time To Clean, PM2.5 (number of particles the size of smoke and bacteria), and last PM10 (number of particles the size of dust, pollen, and mold). The clean ratings are as follows Good (85- 100% 0 – 25 particles), Fair (70 – 84% 26 – 80 particles), and Poor (0 – 69% 81 – 430+ particles). The front display mirrors the main top display (clean air, time to clean, PM 2.5, PM10). You can also check filter life that has a rundown on how many minutes are left. I believe they state the filter should be good for 6 – 12 months before needing to replace. To replace the filter is simple. You just remove the back, pull out the filter, put in a new filter, and put back on the back and bam. You are good to go. Third, this device can move some serious air. If you are sitting next to it and change the fan speed you can feel the difference of how much or how little air it is moving. Which I thought was great. It doesn’t get very loud. My measurements were as follows (47 dB low, 49 dB medium, 55 dB high, 62 dB max.). Fourth, the controls are simple and intuitive and all onboard. Going left to right, top to bottom, you have your Fan up/down, Power button, Air Info (which cycles between Clean, Time to Clean, PM2.5, PM10), Auto Mode, Filter Life, Time To Clean Hour Amount up/down, and Brightness (high, low, off). When the lights are off you have a dim power button and light button which doesn’t distract me when in a pitch-black room. Which I applaud as most others get this wrong or don’t think of. It comes with a remote that allows you to do all the things I just mentioned. The remote itself is large (which can be a pro or a con), lightweight, requires moderate pressure to press, with nearly no pre/post travel, and a crisp ending click. It works via IR which means you need to point it directly at the device for it to work. I think they say within 15 feet. Unfortunately, for me there is a jingle every time you press a button on the device itself (physically onboard and with the remote) which can be a good thing. Or if you’re my dog who has an issue with beeps absolutely terrifying. And there is no way to disable this as far as I am aware. Which makes it a con from my point of view. Fifth, it has an QR code on the top right (as a sticker that can be removed) that allows you to download the manual and anything else you need. Which is nice to have onboard yet again. CONCLUSION: I absolutely love this thing. I’ve tried other AirPurifiers but this one is my favorite as I think Shark absolutely nailed it. Which is a common theme for Shark as they not only make great products, but you can tell that they spend a lot of time thinking of little details and getting them right which is what separates them from the competition. For example, if you remove the back (to get to the filter) it will disable the power button so you can’t turn it on. You’ll find little things like that all over this device. Which makes it an easy and high recommendation from me.

Powerful and quiet operation. Can crank it up when necessary.

Quiet and no worries. I also have other brands air purifiers. Now they all showing clean air most time of the day. It does take a few days for it to settle down. So if you find it showing low clean air percentage for first few days after turned on, it is doing its job. I put it in auto mode.

Works well not particularly noisy and the automatic filter settings make it very simple to use.

This air purifier works well. The air seems to be lighter and It gets rid of the odors in my house. My dog is sneezing less since I got it. Just a little loud when it’s on high

Great air purifier super quiet and definitely worth it if you have allergies I have noticed my allergies stay more tamed with this. For some reason when you cook and don’t vent windows it detects air quality goes down. I’m sure that there are more particles in the air when cooking but not necessarily harmful.

This unit is great and really works. It really detects odors in the air and adjust when you have the settings on auto detect. It cleans the air and goes back to a low setting. I don’t have as much dust accumulation as I use too which makes the air cleaner. It’s been a good unit

We have a couple of other air purifiers in our house. A few of us suffer from allergies in our home, and my wife thought they were good investments since the beginning of the COVID pandemic. We were stuck in our house most of the time with our three sons and the purifiers seemed to do an excellent job of taking odors out of our home, but 2 of my sons usually wake up sneezing so we thought another purifier in their room might be a great idea. In comes the new Shark Air Purifier, and I can say that my sons love having this new air purifier in their bedroom. They no longer wake up with fits of sneezing, first thing in the morning, and yes, their bedroom now smells nicer. There has been a noticeable difference in air quality since we set this up in their room. Setup process is super easy. You need to open the side panel to take out the filter and remove the plastic wrap before placing it back and closing the panel again. Once you get it plugged in, you can control it from the very vibrant touch panel or from the convenient remote. It immediately checked the quality of the air, and we set it to auto mode and it started cleaning the air. Within half an hour, it showed that it was now at 100% air quality and has stayed there since, for the most part. It is super quiet, and you can hardly tell that it is on. My sons’ gaming laptops are way louder than this air purifier. They set the remote on their nightstand, but I don’t think they’ve even had to use it since it’s just on auto mode. There is a nice panel on the side of the unit as well, so you can see the air quality without having to walk up to it and look down at the top panel. Again, this has changed my sons’ sleeping and waking routines. They have been able to sleep in a bit more and don’t wake with fits of sneezing. We have a new pup that sleeps with them in their room, and this has also done a wonderful job of making their room smell better. No more pet smell. This is a fantastic addition to anyone looking to remove cooking, pet smells from their home, or anyone who suffers from allergens. An easy recommendation.

Love the shark air purifier. It works so good, i was having some breathing issues due to the California fires and dust. Within 24 hours i could breath so much better.

This thing working great, it always sit on living room for the shake if kichen cooking smell,

Finally I got the air purifier I was looking for..it is a Quality made product with very nice features. Too console is very convenient if you are not using remote. It’s easy to operate.
