Told me I had clean air out of the box ...doubt it

I bought this 2 weeks ago. The minute I plugged it in it said air was 100%. I left it alone and in the next 48 hours- still at 100%. I tried the perfume test , spraying about a foot away from the back of the unit, it went on with the fans at 2 for about 15 minutes then went back to 100%/eco. I even left the patio door open with "very high" pollen count outside, never went on. I know I have dust and I can see dog hair all over my tile floors. Don't think this was worth the price tag.
No, I would not recommend this to a friend.

Absolutely the best HEPA Air Filter on the market. And of you have indoor pets, this is a must have. For anyone who has medical needs, suffers from allergies, Lives in a metro city area where air quality is usually a challenge or any/all those plus just wants a clear, clean, crisp, fresh air, look no further, this is the HEPA Filter system for you. Its worth 3x what it sells for, and worth every penny. Enjoy.

My allergies have gotten so much better since purchasing! So much so I am tempted to stay inside! Does say air quality is 100% a lot, but I always run it after opening doors.

Shark Air Purifier Review
on April 1, 2026
Posted by: 215_Edd
Gender:Male
I’ve been using the Shark air purifier for a bit now, and honestly, it’s been a great addition to my room. Right away, I noticed how quickly it starts cleaning the air—the display shows real-time air quality, which is actually pretty cool to watch.
One thing I really like is how quiet it is. Even when it ramps up, it’s not annoying, so I can leave it running while I sleep or chill. The design is also clean and modern, so it doesn’t look out of place at all.
I have it set up near my window AC unit, and it definitely helps keep the air feeling fresher, especially with dust or stuff coming in from outside. The airflow is strong, and it seems to pick up particles fast.
Another plus is the “NeverChange” filter system—it saves money since you don’t have to replace filters constantly, which is a big win long term.
Overall, I’d definitely recommend it if you want cleaner air, less dust, and a noticeable difference in air quality.
I would recommend this to a friend!

A Must For Clean Air.
on April 2, 2026
Posted by: Stephy Steph
Gender:Female
This filter does a very good job of purifying the quality of air in your home. It’s very easy to set up clean up is a snap. Just remove all the filters and wash them with soap and water and it’s ready to use after they are dried. As someone who has allergies and asthma I recommend this product for those who have respiratory conditions. I really like how it has a digital display which indicates the level of the air quality in your hole. It’s very good to use in the kitchen to remove air borne odors or air pollutants after cooking.
I would recommend this to a friend!

Its ok but prefer previous model

I have had this model for a few weeks now, I had the heater and fan combo before and this is what they sent me as a replacement when my other one stopped working. It works ok, I actually think it doesn't work as well as the last one because when we cook this one doesn't go on right away like the last one did. Other than this it seems to filter the air well. I miss the fan and heater function. My hope is that this one will last longer than the last one did.
No, I would not recommend this to a friend.
