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

There's air purifiers are amazing! They work so well that I have several in my home. Easy cleaning, easy hepa filter replacement and easy to read display.

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.

This thing just keeps on chugging! Its easy to use (the interface is simple), filters last a fair amount of time, the main filters are easy to change and source, and the pre-filter screens are super simple to clean and replace. It helped my family get through the winter without catching the ick. Hands down, the best air purifier I've ever had.

The air was 100% pure then hooked eggs and it nose dived to 0% and started scrubbing the air hard until it got it back to 100%! So I guess it works! NOTE: when I turned on the humidifier — our air quality dropped to 70%! So I’m not going to use the humidifier any more. Or might buy an EVAPORATIVE HUMIDIFIER one day

I am totally glad pulled the trigger and purchased this. My husband came in a month ago with a terrible cough and cold that lasted for weeks. Usually once I person brings it in the home, the entire home gets affected. He's suffered from respiratory issues all his life while I'm the opposite with no problems at all, however this time it passed over to me and it left me hacking for weeks non stop, nightfall was the worst. I'd finally had enough and bought this and when I tell you I no longer wake up in the middle of the night coughing, I am sleeping like a baby. The numbers started hovering around 84/85 then even dropped to turn the ring yellow when I initially powered it on,which was shocking because I just new my home was full of toxins and such, then the numbers started climbing as the day went on which made me very happy. In a days time my air quality is at 100% on the first and 2nd floor level of a 1475sqft townhome apartment. This thing is superb. I plan on getting another unit as soon as my wallet allows it but this is undeniably the best health investment I've ever made, so good I am only writing after day 2 of use. Thank you Shark!!
