Review on HAPHID 1-Pack Negative Ion/Plug in Air Purifier: Up to 34 🌬️ Million Negative Ions/Sec, Filterless Cleaning of Pollutants, Odors, Pet Smells & More! by Brenda Belcher

Well, I'm not going to be very helpful. I had a lot of allergy problems so I bought this product. While waiting for delivery I wondered if my CPAP machine was the culprit so I put on new filters, washed the mask etc. I feel better but was it the ionizer or my dirty CPAP. My wife thinks the air is a little fresher, but I'm not thrilled. In any case, it's a reasonable price to try.
