HAPHID Ionizer Air Purifier/Plug In Air Purifier Ion Generator with Highest Output - Up to 32 Million Anions/Sec,Portable Filterless&Ion Air Purifier for Purify: Odors,Pets Smell Etc (3-Pack,Silver)

Ok, I read all the reviews and decided to give these a try. I got the 3 pack. I have 3 dogs, and we hike daily, often getting wet from sudden showers or because I let them go for a dunk in streams, deep puddles, lakes, etc. And then my house smells of wet dog for days! One of my dogs also has skin problems, not bad but enough that she often has a musky odor to her, which permeates the entire house. So when they arrived, I placed one in the livingroom, one in my bedroom, and one in the family room, which is always the worst smelling room because all of their beds are in that room. After 3 days, to my dismay, every morning I'd wake up, walk into the family room and the funky smell would hit me smack in the nose. And I thought, these things don't work worth a darn! I unplugged the one in my bedroom, to pack up to return... and thought "wait a minute... that family room is big, 13X11 feet big! So, I placed the one I had just removed on the opposite side of the family room from the one that was already working in there. BINGO! Within hours the family room smelled NORMAL! WITHOUT washing dog beds for the umpteenth time, without shampooing carpets again, and without bathing the dogs! That was a week ago. I have not had a single dog odor in the entire house since then. Seems the smells were all coming from that family room! So yes, these things do work, and they work well. But if you're using them in a large room, you'll need more than one in there to do the job! I read reviews where people were returning them because the directions say to not leave them on if you're leaving the house for long periods. I honestly don't think they mean overnight, or longs days at work! They're talking about going away for a few weeks or months. The exposed tiny filaments that actually do the ion charging can build up with dust, which in turn can cause a flash which can cause a fire. So of COURSE you're remove them if you leaving for a long period, you DO have to clean them off monthly, or as often as you see a dust build up on them. Mine have been in use for about 2 weeks now, maybe a little longer, and there is still no build up on the little "fingers", so unless you have a very dusty home, I don't think it will become a problem. Just do regular checks on them to make sure everything is clean. And enjoy your clean smelling home!

The pice is great, my allergies are much better. The only complaint I have is how hard it is to plug something else in at the same time in the same outlet.

I just rated ,not useful , not working and worth penny,This is my opinion and if you like to buy it ,you'll not be happy at all.1st no ion coming our from ionizer2nd will not able to clean air because not working3rd wasting time to talk to customers service for refund4th you have to drive Amazon return place to drop off5th waiting for refund ,Much expensive is time ,don't waste it enjoy your time with something else.........Buy better one

i will likely buy a few more for other rooms in the home. i'm happy with them. i think the yare working. i see dust on the wall next to where it's plugged in so i know it's doing something. I'm hoping a few in the basement will help with the smells from the very old, dark, dank dirty basement iin this super old home.

Just had our air ducks cleaned. Used these to clean flying air in rooms. Differently made as a difference.
