The Koios Purifier Indoor Air Cleaner is an affordable, durable, and surprisingly child-friendly air purifying unit. It can become a little loud sometimes, and its area of effect is limited to the room it’s in, but for $55.00 it’s hard to complain. Check out our best air purifier under 100 list for more great air purifiers! So, let’s get to it and see if this air purifier ranks in the top-rated air purifiers list.

Why We Like It – Koios Upgraded Purifier

The Koios Air Purifier Indoor unit is not only an excellent air purifier, but it looks quite nice and can add a spark of class to whatever room you decide to place it. It can double as a night light for your kid or you (don’t worry, I won’t tell), and can kill smoke and pet dander just as easily as dust particles.

Pros
  • Kills 99.97% of particles and odors
  • Doubles as a night light
  • Affordable
Cons
  • A little bit loud
  • Night light can’t be turned off
  • Will need more than one for multiple rooms

Performance

Unlike the Honeywell HPA 300, this Koios Air Purifier improves air quality via a three-stage filtration system: fine preliminary (pre-filter), true HEPA filter, and an activated carbon filter. The filtration systems work one after the other to kill 99.97% of particles and odors, including pet dander, to give the room the best air possible. The true HEPA Technology also allows the unit to eliminate dust, pollen, and even smoke from rooms. If this sounds like too much and you just want a basic office odor allergies eliminator, we suggest the GermGuardian GG1000 Pluggable Deodorizer Guardian. Go through our Levoit Air Purifier for Large Room review and Levoit LV-H132 review for additional units.

Design

The Koios True HEPA Air Purifier features a one-button operation that controls both the fan speed and the stage filtration night light. The IonPacific Ionbox also features a nightlight. It couldn’t be easier to both clean your air and protect your state of mind while you’re sleeping. Anyone with a child will know how scary they get when their rooms are completely dark. Because the unit can eliminate odors from smoke dust pets and many other sources you’d expect it to be rather large, like the GermGuardian AC4825. But in fact, it’s actually quite small, compact, and easily transportable from room to room for a whole house clean. Be sure to also check out our IQAir Healthpro Plus Air Purifier review.

Value

The Koios Air Purifier reviews on Amazon rank it at 4.5 stars out of 5 based on 3,320 reviews. Not too shabby. The unit retails on Amazon for $55.00 which is a decent price for an air purifier that filters out the likes of smoke and pet dander. The Levoit Filtration Eliminators Vista 200 retails for almost $90.00 on Amazon and is almost exactly comparable to the Koios. And, while the Medify Air is by far the best, it’s incredibly expensive. The Koios Upgraded Purifier, if you’re not already sold on it for some reason, is also 100% Ozone Free Certified by Carb.

Koios Upgraded Purifier Wrap Up

The Koios Upgraded Air Purifier is a sleek, compact air purifier that can double as a night light for your little one. It’s mystifying that the night light cannot be turned off though, so let’s hope the people at Koios resolve this issue with their next purifier. Overall, though, for the performance, it’s capable of and what it’s priced at, you can’t go wrong.
