Ionizer Air Purifier/Plug In Air Purifier Ion Generator with Highest Output - Up to 32 Million Anions/Sec, Portable Odrx & Ion Air Purifier for Purify: Odors, Pets Smell, Etc (5-Pack)

These things have been knocking stuff out of the air since I got them, my lungs thank you!

Basically, there is more information available about these negative ion generators (ionizers) than any others that I have seen out here that are similar. For THESE ionizers they say that they produce 32 million anions/cm3, and that their coverage area is 300 sq.ft. And when I was looking at all of the other ionizers that I could find out here, I didn't find any other ones that gave those two pieces of important information. Some said how many negative ions that they produced ONLY. And some said what the coverage area was ONLY. But I couldn't find any that said both. What's REALLY disappointing though, is that the most popular and best selling ionizers out here that have over like 10.000 ratings, don't even give EITHER of those pieces of information, yet that many people have blindly bought them.And ultimately, when I did the research I discovered that even the information given for these ionizers is basically worthless to compare them with any others or to determine how effective they are... So what information DO you need to know to determine that? The main piece of information that you need to know, of course, is how many negative ions are produced. And from what I understand, the standard term for that would be "negative ion density." Which is the number of negative ions contained per unit volume, and is commonly shown as: pcs/cm3, ions/cc, or pcs/cc. And no matter what they are shown as they are all the same thing. For these ionizers though, it's given as anions/sec and anions/cm3. But I believe that's technically probably the same thing.Anyway, an ionizer's performance can't be determined with just the negative ion output and the coverage area. I've learned that it's also very important to know what's called the "blow off direction," which is the negative ion count detected at a certain distance away from the ionizer. Here are some examples of what a blow off direction measurement might look like:- 20,000,000 pcs/cc at 0in- 1,000,000 pcs/cc at 20in (50cm)- 700,000 pcs/cc at 39in (1m)Next, it's good to know that an ionizer doesn't have a narrow coverage area, or else you'll only benefit from it when you're directly in front of it. It's also important that they spread in every direction because as time passes negative ions vanish quickly. So for this you'll want to look for something called "angled directions," which might be shown like this:- 500,000 pcs/cc in 30 degrees at 79in (2m)- 150,000 pcs/cc in 90 degrees at 98in (2.5m)- 10,000 pcs/cc in 180 degrees at 39in (1m)Apparently, it's also important to know the life span of an ionizer too, which is generally determined by the ionizing needles. And worn out needles can lower negative ion counts and produce a lot of harmful ozone.Jeezom pieces... There's even a few more things I didn't detail here, lol. To see where I got all of this information just search the web for "How to choose the best negative ion generator," and the first result that doesn't have the word "Sponsored" in front of it should be the right website. You'll know it's the right one because it's a weird Japanese website. Well, I hope this was helpful as I spent quite a bit of time finding, making sense of, and then explaining all of this information. And there was nothing in it for me. I paid for these ionizers and my review for this wasn't in exchange for a free item this time. I just do something like this when I can because I believe that we will never progress as societies or evolve as humans unless we all realize that it's just as important to better each other as it is to better ourselves.

IT DOES NOT HAVE STRENGTH TO DO WHAT IS PROJECTED TO DO.I HAVE ONE IN THE BATHROOM & TWO IN THE KITCHEN & IT DOES NOT WORK.MAYBE THE PRODUCT NEEDS TO BE WITH MORE STRENGTH TO BE EFFECTIVE.

We live in northern Maine and have a wood/oil furnace for heat. We also have two furry kitties. Wood burning is wonderful heat but leaves a lot of dust and residue and our cats leave fur and dander in the air. It was frustrating to see all the dust and dander left in the air and we were breathing it in. After using very expensive air purifiers that used expensive replacement filters and raised our electric bill substantially, I tried these a couple of weeks ago. Impressed at the Immediate difference in our air quality and yes, we visually see and breathe the difference, we have one in everyroom. It takes a lot for me to endorse a product but trust me when I say theses REALLY WORK. If you burn wood or coal and have pets you will notice an immediate difference like we have!

I had hope for these as we have used ion based air cleaners. I placed them in the bathroom outlets. After several months I noticed NO change and did not see any buildup on the bottom brushes on any of the units. I would suggest that you save your money and skip this product.

Minimizes the smell of smoke in my house. Big improvement.

Very expensive. Purchased for my mom, said they work okay.

Don't need to dust as often the air seems cleaner
