Shark HP152 NeverChange Air Purifier, 5-Year Filter, Save $300+ on Filter Replacements, Large Room, 650sq. Odor Neutralizer Technology, Captures 99.98% of Particles,

Bought to help with my allergies but also to help control smoke, odors in a tightly built new home with a cheap built in hood exhaust fan. Have not used the air scent infuser. House frequently at no need to filter according to purifier's read out (surprised at that-but just knowing that is good). I guess the air is filtered well by air filter in furnace/air conditioner (I do use hi grade filter) and the tight new home construction helps as well. If open windows or doors more then it will kick more often. Does work hard when cooking for awhile and air improves over time. Subjectively my allergies, sinuses do seem to have less trouble but hard to assess that but usually I get a sinus infections 1-2x year this time none but I have been aggressive with early Netti Pot intervention as well so....? Hey surely the purifier is helping some too? Or at least the tightly built home and high end air filter? So to me this purifier is just another tool in my sinus allergy battle BUT the purifier does help with odors, smoke for sure from cooking. I do move it to different rooms at times too but mainly in my open kitchen/living room area. I do not have a pet (allergies to animal fur) so do not know how it works with that but I believe a different model suggested for that purpose but I forget.

I have episodic coughing triggered by various things. Bought this 1 1/2 years ago. Called Shark customer service once and they talked me through minor problem. I have this upstairs in my bedroom and the sensitivity is amazing. It.stays on 100% most of the time and comes on and stays on till air clear again. I can just straighten bed covers and it will come on. Cooking downstairs, 13 stairs and go back upstairs and it has come on maybe at 79% till air clear again. I love this air purifier. I live in the.mountains and nearby fires at times and comes on and I know it's working. Money well spent! When it is on full blast, never very long, can be a bit noisy, but not like a box fan. Good airflow so that.nice in the summer, too.

I really like this. I keep it near the litter box and even though we change the litter often you can get a whiff every now and then. Not anymore. I had little faith in the order removing ability but I am a believer.

I’m shocked. It is in my room where my dogs sleep. I clean their bed and it still smells like dog. I have a whole hair purifier. This one makes my room smell nice will update after I have had it longer

I've had this running continuously in a downstair/basement apartment for several months, and I'm quite impressed. Occasionally if it kicks in when detecting a lot of sudden dust/smoke/vape or whatever, it can be kind of loud, but it's not an overly annoying sound, so even those brief times are no problem. Very quiet, easy to clean every couple months, reliable. I have no interest in the scent pod feature, so I can't give an opinion there.
