CO-Z Portable Room Air Purifier, Light Desktop Air Ionizer for Bedroom, Apartment, Kitchen, Office, Quiet Personal Air Cleaner & Freshener for Dust Particles, Smoke, Pet Dander Smell Odor Control

Very nice gadget. Sits perfectly on our nightstand and provides assurance the air is clean. It’s colorful too, it’s nice night light or you can turn illumination off.We put it in the car and really notice the difference in air quality.

Item worked fine, however it was just a bit too small for the area I used it for. No visual button indicators either so learning how to shut it completely off took a couple minutes.

It seems to work well, it cuts through odors well enough and the battery life is accurate. It also significantly cuts down on airborne dust in a small room.While running, it leaves a tickle in my nose... not quite a smell really. My sister doesn't notice it. I think it's just the charged particles, I used to get the same sensation working in an electronics lab at the local science museum.When the battery starts to run low (for maybe the last 30 minutes of battery life) the fan squeaks quietly.If you have a small room and don't want to deal with filters, I'd recommend it at the price I paid.

Compact, well designed product that is quietly efficient.

Solid product for cost

I love ionizers and have SEVERAL of them throughout my home. This is small and would not look out of place on any counter or tabletop in your home. It charges a Micro USB cord which is included. When I first turned mine on, it was immediately green, which means I have good quality air according to the built in sensor. You can select 1 of 3 speeds or keep it on automatic where it is supposed to adjust the speeds itself if necessary from poor air quality.This has not changed the scent in the room (there was no odor at all) but if you put your nose up close to this, you can smell a very clean scent of the ions. I like this. As a test, I did exhale my vape at it when I had it on Auto. It immediately turned red for a few, then yellow, and then back to green for clean air. So the sensor is working, but I did not notice the fan move to high speed though like it is supposed to. OK, I figured this out. I unplugged the charging cord and on auto, the fan will go into high speed on its' own. When it is plugged in, it will charge only and not work properly. This is not stated in the manual and I tried several outlets and several charging bricks and several cords with the same results every time. This works by a charged internal battery only. The clean air is stronger too when the cord was removed. So this only works properly when it is charged, not plugged in 24/7. BUT, even on the battery, it works for 3 or 4 minutes ONLY and then shuts off. For that reason only, I would pass on this item. If it worked both ways by battery and a cord plugged in, and stayed on consistently, I would love it. I may have a defective item though too?? I will ask the seller as it is not stated in the manual.The seller has replaced my item with a new one. Both items work exactly the same. This will not work if this is plugged in at all. It will shut off after a minute or 2 on a fully charged battery. Both items do this. This is NOT a good purifier.

This air purifier is small but boy is it mighty. I have it in my room and usually, I am sneezing and all stuffy because of allergies but with this, I am breathing so much easier. I didn't realize just how well it was working until my mother said something to me about her noticing I wasn't sniffling as much as I used to. So, this air purifier is amazing if you have allergies and want something that is great for small rooms. I've bought a larger one for my living room because the small one worked so well. It is also amazing for helping to keep the level of smoke down as well and I am just breathing so much better after using this for a few weeks. Couldn't be happier.

This USB rechargeable ionizer is lightweight, small, beautiful, and portable. You can move it easily from room to room or even take it with you on a trip. It has an automatic setting, as well as three manual settings.The power and setting button is easy to find and use. In operation, it is whisper quiet, even at the highest settings. There are no filters to change. Particles of dust and pollen are charged and fall out of the air. Clear them from surfaces with a dust cloth.I like it very much.
