I recently purchased the Shark Air Purifier, and overall, I'm quite pleased with its performance. Here's my breakdown: Pros: - Excellent air purification: The unit effectively cleans the air in my home. - Outstanding odor neutralization: The added odor neutralizer feature is a game-changer. When I run the purifier at full blast, my home smells incredibly clean and fresh. - Noticeable improvement: I can feel the difference in air quality when the purifier is running. Cons: - Noise level: As someone with allergies who prefers to run air purifiers at maximum settings, I find this unit extremely loud at full blast. This can be disruptive, especially during quiet activities or sleep. Overall Impression: The Shark Air Purifier does an excellent job of cleaning the air and eliminating odors. The odor neutralizer is particularly impressive, leaving my home smelling fresh and clean. However, the noise level at higher settings is a significant drawback for me, given my need to run it at full capacity due to allergies. Recommendation: I would recommend this product to those who prioritize effective air cleaning and odor control, and who don't mind some background noise or plan to use it primarily at lower, quieter settings. For allergy sufferers or light sleepers who need constant high-power air purification, the noise level might be a concern.

[This review was collected as part of a promotion.] This air purifier is extremely quiet. We have a 3,500 sq Ft home and this air purifier does the trick for the first and second floor. This purifier also allows us to have the windows open and in our experience, minimizes allergy symptoms due to the fresh air. We notified an immediate positive difference in how our home smelled after using this machine for a night. Set up is super easy, just unpack it from the box, put it in the corner and plug it in and the machine does the work!

My husband has allergies and asthma. Immediately after purchasing this air purifier, his breathing improved. He went from nightly asthma attacks to none. As other reviewers have mentioned, the quality sensor appears to be effective as well. Even without allergies, the air is noticeably purer in our house. We have a large, ~1700 square foot downstairs and this purifier handles it well. The device is mostly quiet and unobtrusive. Although it is large, it doesn't get in our way, and I don't feel like it creates noise pollution. Given its effectiveness, range, and cost, I am very happy with the purchase.

The sensor reading never changed off of 100. Returned the item.

Absolutely loving my Shark never change

Great air purifier. I have several of these in two different homes and even ordered for my kids.

We started noticing a difference in our stuffy sinus relief at about day 2. Would recommend

Works great, removes cooking odors

Like it so far. Seasoned some cast iron in the oven which caused some odors and it showed red and sped up until it showed 100% again.
