[This review was collected as part of a promotion.] I felt like the air in our house is always dusty and I have no idea why! I've been using this new filter for a little while and it's helped to make a huge difference in our air quality. There is practically no assembly required! I love that there is a child lock for the buttons and it's super quiet! I've been keeping it on auto mode and I don't have to worry about it. I put it out in our refinished shop and it started out at 65%, yikes!! So now I defiantly need a second one!

[This review was collected as part of a promotion.] Love my new Shark Air Purifier! My daughter has been battling respiratory issues this summer and I truly think this air purifier is helping her feel better. It is cool to see the % change as the air purifier cleans the air and I love how the filter lasts up to 5 years! I highly recommend this air purifier.

[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.

My doctor recommended that we buy an air purifier for our house to help reduce dust. The timing of our order was perfect, because right when it arrived, the smoke from nearby wildfires was blowing into our area and the air quality took a dive. Our house feels so much nicer now and keeps it clear of all of the usual dust and dirt particles, as well as wildfire smoke. (I also have to add: the little chime is has when you push a button is absolutely darling!)

[This review was collected as part of a promotion.] Loving my new air purifier, with its sleek design. It tucks away perfectly in my living room to be hard at work, without even knowing it's there. I love how easy the setup was and am so excited I won't have to continuously be changing the filter since this one lasts much long.

After a few months our unit began to have a high pitch whistle. We clean the unit once a week and we're dumbfounded by why it was doing this. I took a lownpressure air nozzle to the entire unit and still it whistled. I wiped the accessible area with a microfiber towel, no change. I called SHARK and after they saw and hears, via video chat, the issue, they immediately sent a replacement. I hope this new one doesn't begin to whistle in the next few months. We love SHARK. They are amazing at replacing warrantied units. Always get a warranty, I've used for every SHARK unit we own.

[This review was collected as part of a promotion.] I just received it but what I can say so far is that it is quiet. I have a baby so that is important. Also the odor neutralizer smells good, I will not be using it until my baby is older however. I am looking forward to seeing how it does compared to other purifiers I've used.

This is the best air filter ever. It is so automatic you just set it up and you never have to do anytihng else. I cooked bacon in the oven this morning and never realized how the smell affected the air quality until i heard the fan come on and looked at the air quality was done to 73%. Shortly there after it was back to 100%.

[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.

[This review was collected as part of a promotion.] Cleaner air with little to no effort involved by me? Sign me up yesterday! I love how easy it is to use the Shark Never Change Air Purifier in my home. The design is sleek, it's lightweight and very quiet when in use. The air filters are locate on the sides of the machine making it easy to remove them and clean them out when needed. I love how I don't have to replace any filters! Just clean the dust from them occasionally and put back in place. The HEPA filter is easy to remove and clean out when needed. I have been using my Shark Air Purifier for about a month now and I have only pulled the filters out and wiped them clean once. The control panel is easy to see and use. I keep mine on auto so it runs as needed. The odor neutralizing technology releases a fresh scent to help keep the air smelling fresh and clean while removing odors and toxins from the air. I would highly recommend having a Shark Never Change Air Purifier in every home!
