When your Molekule air purifier arrives, you will receive the air purifier with a cover, a user manual, and instructions on how to set up the purifier. Setting up the air purifier is quick and easy.

What is a PECO-HEPA Tri-Power filter?

A PECO-HEPA Tri-Power filter uses a combination of three technologies–carbon, HEPA, and PECO–to neutralize the army of offenders in your air. The first line of defense is activated carbon, which works to remove odors and gasses. Next is HEPA. Well-known in the air purification industry, HEPA does an impressive job capturing pollutant particles in the matrix of a filter’s fibers. The third and final layer of protection is PECO. Short for photoelectrochemical oxidation, PECO is a light-activated nanotechnology that not only captures pollutants but destroys them at a molecular level. In fancy science terms, PECO uses free radicals to oxidize (break down) harmful pollutants into harmless, naturally occurring elements like water. Power-packed and highly effective, Molekule’s PECO-HEPA Tri-Power filter provides you with three times the defense against airborne pollutants compared to traditional filters.

What airborne pollutants do Molekule air purifiers target?

  • Pet dander
  • Wildfire smoke
  • Viruses
  • Dust
  • Dust mites
  • Pollen
  • Mold
  • VOCs

Which air purifier is best for my living space?

There are two models to choose from when you buy a Molekule air purifier, the Air Pro and the Air Mini+. The Air Pro covers up to 1,000 square feet, which makes it great for large living spaces like bedrooms and living rooms. The Air Mini+ is a miniature version of the Air Pro and covers up to 250 square feet, making it perfect for small spaces like kids’ bedrooms and home offices.

Is WiFi needed to use the air purifiers?

No. Your Molekule air purifier will continue to work its magic keeping your air clean regardless if WiFi is turned on. You can also disable WiFi on the air purifier’s display screen once it has been enabled. When WiFi is disabled, you will not be able to control the air purifier’s settings from your phone, see the Indoor Air Report on your phone, or use any other functions on the mobile app. 

How loud is the air purifier?

The Air Pro has six manual fan speeds, with level one being the quietest and level six being the loudest. At level one, the fan is quiet. At level three, the fan is equivalent to white noise. And by level six, get ready for take-off because the fan is loud. Levels one through three are great for everyday use when the air quality is good and levels four through six are great for when you leave the house or have bad air quality.

Our Experience With the Molekule Air Pro Purifier

When the Air Pro arrived, I was immediately drawn to the detailed packaging, which showcases a few of the air purifier’s features in white writing and stylized graphics. The instruction card is designed in a similar way, which makes setting up the purifier a smooth and easy process. From start to finish, it only took about 10 minutes to get the air purifier up and running, and that included assembling the filter and pairing the device to my phone.

I was initially hesitant about the purifier being connected to WiFi but was quickly reassured when I realized WiFi can be temporarily turned off or disabled entirely. I also came to appreciate the features of the mobile app, like the Indoor Air Report and Air Score. The app also shows several air quality factors, like VOCs, PM2.5 (fine particles like dust), and PM10 (coarse particles like pet dander). Being able to see what particles are detected in my house gives me a better understanding of the pollutants I’m exposed to daily, as well as peace of mind knowing the Air Pro is working around the clock to get rid of them.

As a dog owner, I love that Molekule air purifiers target pet dander. My dog, Micah, is a high-energy goldendoodle who loves outdoor adventures, indoor games of hide-and-seek, and snuggling on the bed (with his head on the pillow). He’s 50 lbs of fluff and makes his presence known through lots of puppy love and dog fur. So, it’s not surprising that, despite being a low-shedding breed, Micah’s doodle fluff spreads dander throughout the house. With the Air Pro, I’m confident that Micah’s dander is being detected and removed from the air, and with the mobile app, I have the data to prove it. Even without measurable data, I can feel the air around me is cleaner. The sleek, modern design also matches the décor of any home, which is great since air purifiers aren’t devices you can discretely hide.

My only complaint is the air purifier doesn’t have a dark mode. While the blue light is necessary for the PECO technology to work effectively, it also means the device glows at night with no option for dimming it or turning it off. I have the Air Pro in my living room, so the light isn’t an issue, but it could be bothersome in a bedroom, especially if you like sleeping in a dark room. Overall, I love the Air Pro and would highly recommend it to anyone looking for a premium air purifier and effective clean air solution.
