ClarifionAir Ionizers for Home (3 Pack), Negative Ion Filtration System, Quiet Air Freshener for Bedroom, Office, Kitchen, Portable Air Filter Odor, Smoke Dust, Pets, Eliminator, Mini Air Cleaner

These have no fans and no ozone smell. They need to be placed in a well ventilated area (air flow). I have one each in my living room, kitchen and bedroom. I smoke (never in the bedroom) and these take care of the residual stench. I have no lingering cooking smells, not even fish, in the kitchen. Best of all, I have noticed I am sleeping better as my sinuses stay clear (I have allergies). These are absolutely quiet (no noise at all) and small, about the size of a pack of smokes. They do emit a blue light from the top, but not enough to cause a distraction. Very effective for such a small device. I do recommend these. I leave them plugged in 24/7, and no, they are not energy hogs as they barely use any electricity. One of my better "oh why not" buys.

I put one of these in our Master bathroom (where we have two enclosed litter boxes for our three cats and the bathroom is quite large) and one in the Master bedroom (Haven't figured out where to put the third yet...lol) and so far my breathing has improved, I'm not as congested, there appears to be less dust around, and in the bathroom, there doesn't seem to be a ANY persistent odors from us OR the litter boxes... so far these have been a Godsend... and people that are complaining that their units are getting hot... mine aren't even a touch warm and they are plugged in and running 24 hours a day and have been for the last two weeks...

All I can say is that these are excellent! Our house was so dusty even after we installed a special air cleaner when we replaced our furnace. I have allergies especially to dust mites. My husband read about these Clarifon devices. I ordered 3 and easily plugged them in and we could tell an immediate difference. The air is clean and fresh and way less dust! I plan on buying 3 more for our basement. Plus, my allergies are so much better.

I purchased this particular product specifically for my bedroom. My house is in the country and very dusty. The purifier was purchased to help provide cleaner air during my hours of sleep. I read through the reviews. Some mentioned the negative ion cleanup needed around the outlet area and the LED light. This product attracted me with the following attributes which are true (thus my 3-star review): small size to fit many different areas; easy plug-in; lack of noise; technology that skips having to purchase filters; and a response to an online question from the actual manufacturer.Once the product arrived, I read the instruction pamphlet (printed in such a faint font I needed a magnifying glass to read!). Noted were details I did not notice on the Amazon listing: optimal height to install is 5-feet above ground and away from furniture (note the two manufacturer photos of the device above a bed and a chair!) and how to manage the dark dust that may fall from the device. The best place in the bedroom was near the bed between a cabinet and nightstand. To deal with the possible black dust residue, I immediately taped up paper around the outlet (see photo) and checked it every day including this morning. There was no dust, thankfully.But the ultimate deal-killer was the LED light. Left alone, it lit up the bedroom at night. After two nights of this, two layers of blue painters tape were taped across the top of the device. It muted the light enough so it did not interrupt our sleep. But after one night, I started wondering about the airflow and if this tape was interrupting it. I reached out to the manufacturer and have not yet received a response. The tape was eased back from the LED light to allow airflow and somewhat block the light. The room still smells dusty after a week of use.Overall, it is sad that this device would not work for my circumstances. It may very well work perfectly for others. I am returning the device and the hunt continues for another bedroom purifier. Thanks for listening.

Definitely work.

I bought 3 pack of the clarifion ionizers on March 18, 2021. I placed one in my bedroom, one in spare bedroom and one in the dining room. I saw the blue light that was on, in my bedroom and never thought to check on the other 2, until I was at a friends house and we were talking about these ionizers. He has a different brand that plugs in, but, he said his has a filter that needs to be cleaned at times. So, when I went home, I checked the ones I have and there is no filter and no way to clean the device I have. I also noted that the one in the spare bedroom and the one in the dining room had no blue light on. Don't know how long these lights haven't been working, but, I would think that they would last more than a year. I paid $94.00 for the 3 of them. The photo shows the warning on the side of the device I have and it says to clean is regularly, there is no panel to take off to clean it inside. I called Amazon where I purchased them and they told me to call Clarifion. I was given their phone #. I called Clarifion and they told me to call Amazon support since I purchased them from Amazon. What a run around. I would not recommend these devices to anyone. As far as I'm concerned, I'm disillusioned with Amazon after being a Prime member for many years.

I would tell anyone about this because we have a wood stove and it cuts back on the smoke

So far so good.What we have noticed is the little dust particles that float around especially in sunlight seem to be mostly gone from the air.
