Air Purifiers for Home Bedroom, KOIOS H13 HEPA Pro Smart Air Purifier with Auto Speed Control for Pets Dust Hair Dander Smoke Allergies, Portable Air Filter with Fragrance Sponge for Small Room Office

I keep this in the bedroom and it works beautifully. No "scent" in that the air outside smells like creosote when the forest fires are active around us like they are now. I have a larger air filter for the rest of the house, but am so glad I bought this one. It is on the second fire season and still is wonderful. Oh, and the lowest setting is very quiet, which is another plus.

I appreciate all the features this unit has from the timer, to the ability to add oils, to the different speeds and the cleaner, fresher air it creates. It was one of the better priced units. I went economical and it works well for the master bedroom. I believe its range is greater than where it is located, but it's doing its job.

This air purifier works great. The air detector function works well when it detects abnormal air quality. The auto and timer functions work well too. When smoke, food odors, and even farts (lol) are detected the fan speed increases to clean the air. I know air must pass through the filter but I do question its quality. The carbon portion looks like a thin porous sheet of black sponge. The air does smell a little different while in use except for smoke odors, which seem to linger for a while. Would still recommend this Air purifier.

The media could not be loaded.  really impressed by the way this purifier works, it's completely touch screen, has a timer, fan control and the best part of it is that you can insert your favorite Cologne/scent in it's storage compartment on the center of this purifier, so far I've noticed my allergies areen't as bad as they used to be and my living room smells great! Totally recommend, really quite as well if u don't wanna wake your kids up like myself lol, 10/10

This was the perfect product for a month. Now it just makes a noise as if the fan is struggling to move. It hasn’t been knocked down it’s just junk.

There were some good things and some not so good things about this. First off, I love KOIOS products and own two other KOIOS air purifiers and they are great! Let me start with the good:- Very compact, it can fit in almost anywhere- Comes with a filter to get you stated- The display is clear and there's a timer that you can set up to 12 hours- Would be ideal for a small cubicle or bathroom- Three speed fan, when on the first and second setting it's very quiet, even the third is not overly loud.The not so good:- As other reviewers stated, it doesn't pull much air hence the quietness- I couldn't get the scent diffuser to work at all, I bought a bottle of diffuser drops and had it to the point that the felt pad was saturated and it still didn't release any of it into the air- The purifier's performance compared to others around the same size isn't worth the price pointOverall, it's not bad. Just remember that it's only effective in a really small area around the size of a cubicle. I really wish I could have gave 5 stars, as their other products are spectacular.

Put this air purifier to my baby's room, so far so good. Works quietly, doesn't take out much of a space and has a great feature of opportunity to add essential oils, which I adore! The air in the room seemingly cleaner and has a nice aroma, which is very helpful after changing a dirty diaper. Overall, didn't find any disadvantages.

Quiet little machine. Many options on timers 2-12 hours. Can sleep with it in the room it's that quiet. Cons...is the little thing they call sponge for fragrance is not good quality, but looking to replace that little disk.
