Very quiet air purifier
on August 20, 2023
Posted by: NinDE
from Delaware
Gender:Male
[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!
I would recommend this to a friend!

Has been helping my asthma.
on September 2, 2023

Works really well and is quiet. My asthma has been a lot better. The wildfire smoke and general pollutants along with poking and such have made this a really tough summer. This air cleaner is really helping. I like that it has the odor pods and that they’re easy to change. The machine is easy to care for too. I want to pick up a second one of these for my bedroom to see if I can sleep better and not have congested lungs and gooey eyes in the mornings.

Units failed in three months.
on August 7, 2025
Posted by: Cherzl
Purchased two units for 2100 sq.ft. house. They worked great for three months. Then they stopped working. Both units would only register 0 clean air. Cleaned the Hepa Filter per the instructions, cleaned all air screens including the sensor on the back. They worked....for two weeks and stopped again. Have cleaned the units every two weeks for three months. Today, neither unit will register. Cleaned them again for the second time in two days and still neither works. It is like they are talking/linked to each other...AI???? Shark replaced one unit but these units do not last 5 hears, they don't even last 1 year. Totally disappointed for the big money, not worth it.

Effective and Great Odor Control but Really Noisy
on June 7, 2025

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.

- 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.
- 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.
I would recommend this to a friend!

Seems to work great....for a week

Broke after 5 days, making a horrendous squealing noise whenever running. Called for support and they couldn't replace it for a few weeks, called back and they still cannot replace it. I'll be honest I'm getting pretty mad at the whole ordeal.

Great for pet allergies, asthma
on February 18, 2024
Posted by: blecovich
from Indiana
Gender:Male
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.

This is the fourth one that’s I’ve gotten due to other three not working and I still have the same problem.
The sensor stays at 100 percent and doesn’t move.
No, I would not recommend this to a friend.
