The Molekule Air Pro purifier is beloved by both home air quality obsessives and casual consumers alike. It’s a high-quality air purifier that aims to keep the air in your home fresh, clean and free of pollutants. Of course, it has a sky-high price tag to match at just under $1,000, too. This begs the question: Is the Molekule air purifier worth it? If you’re asking yourself this question, well, you’ve come to the right place.

Molekule Air Purifier Review

Molekule is a science company, which is an important distinction to make when considering which air purifier to get. To that end, the Molekule team conducts extensive research and rigorous testing on indoor air quality and air cleaning techniques. But the company also works with some of the world’s top independent labs and academic institutions.

All of this is to say that with a Molekule air purifier, you’re getting one of the most advanced air purifiers designed. When you invest in one, you’re getting a unit that destroys the full spectrum of indoor pollutants and breaks them down on a molecular levels.

In fact, Molekule introduced the world’s first molecular air purifier in 2016 with patented technology that brings a new approach to air purification.

Molekule Air Filter Types

A Molekule air purifier comes with two different types of filters.


This is a high-class MERV-12 filter. It cleans out substances with large particles such as dust, smoke and hairs. That type of filter also slows down Volatile Organic Compounds (VOCs) as they pass through to the PECO-filter.


The Photo Electrochemical Oxidation (PECO) filter is a nanocatalyst-coated filter that induces a chemical reaction upon exposure to UV-A light. This action breaks down the pollutants into their molecular components. Additionally, PECO technology meets rigorous performance criteria in FDA guidance for use in helping reduce the risk of viral exposure to SARS-CoV-2, the COVID-19 virus.

Compared to the HEPA standard test, the PECO-filter’s nanotechnology destroys pollutants that are 1000 times smaller. In fact, not many other air purifiers offer this capability — with it, the Molekule air purifier not only collects, but destroys air pollutants such as VOCs, chemicals, mold, allergens, viruses, fungi, bacteria and ozone gases.

Molekule ships the air purifier with a package that includes one PECO filter and two pre-filters. It is worth noting, though, that you should replace the pre-filter once every three months. The PECO-filter also needs a replacement after six months.

Molekule Air Room Size Coverage

The Molekule Air Pro purifier is suitable for large rooms that measure up to 1000 square feet. This makes it ideal for large spaces, such as:

  • Living rooms
  • Master bedroom
  • Home offices
  • Workspaces
  • Workshops
  • Children’s rooms

In addition, it provides a 360-degree air intake and purification system, which draws clean air in from all areas of the room.

Molekule Air ACH Rating

If you’re searching for an air purifier, you’ll want to familiarize yourself with the ACH rating, or air changes per hour. It’s an indicator of how many times it can clean the air hourly.

That said, while ACH is a measure of how fast the unit’s fan is, it’s not a suitable measure for a photocatalytic process found in the Molekule air purifier.

When searching for an efficient air purifier, the Air Changes per Hour (ACH) is an indicator of how reliable the unit is. The ACH of an air purifier determines how many times it can clean the air hourly. Instead, you’ll want to use Molekule’s room size coverage measure (600 square feet), as well as destruction metrics such as

  • Formaldehyde: 90% removed in eight hours
  • D-limonene: 99% removed in two hours

Molekule Air CADR Rating

When shopping for an air purifier, it’s best to search for features that enable the unit to clean certain harmful pollutants. One way to measure this is through the Clean Air Delivery Rate, or CADR. This measures the air purifier’s ability to get rid of pollen, dust and smoke, which are the most common pollutants.

If the CADR rating is closer to the room size, then the air purifier is considered efficient at eliminating those types of pollutants.

Molekule does its own internal testing, as opposed to testing done by the external Association of Home Appliances Manufacturers (AHAM) agency. Here’s what it found:

Regardless, Molekule does its own internal testing and maintains transparency on the obtained scientific data:

  • Smoke: 85% removed in 22 minutes
  • Dust: 84% removed in 20 minutes</li>
  • Pollen: 79% removed in 10 minutes

Molekule Air Pro Top Features

The Molekule Air comes with smart, high-quality features that give it an added advantage over other brands. This includes intuitive usability, top-grade parts, App-based remote control and exceptional performance.

You can expect to enjoy the following features.

Wi-Fi Mobile App

The Molekule Air has Wi-Fi compatibility, and you can connect it to your iOS or Android smartphone for remote control. With it, you can turn the air purifier on and off, change fan speed settings, enable dark mode, view filter status and activate automatic filter replacements.

Dual Filtration System

The Molekule Air features a pre-filter at the base and a PECO-filter at the top for dual filtration.

As the air goes through the system from the base, the pre-filter removes the larger particles like dust and hairs. As the air flows through this system, the pre-filter slows down the passage of volatile organic compounds (VOCs).

The PECO process is at the heart of the purification since the filter has a nanotechnology coating. It reacts with an internal UV-A light to destroy pollutants in the air such as viruses, bacteria and fungi.

Dark Mode

Dark mode turns off the UV-A light, which will filter the air without destroying pollutants. You can even schedule it to turn on and off throughout the week in the app.

Environmentally Friendly

The Molekule Air comes with branded filters that destroy VOCs and ozone gases. In addition, doesn’t emit any ozone substances that could pollute the environment. 

Quiet Operation

The noise level is between 41-65 decibels (dBa). At its lowest speed, the device runs at its quietest level of 41 dBa, which is virtually inaudible. Even at its highest speed, the Molekule Air produces 65 dBA of noise which is about the same level as a conversation.


Molekule offers a two-year warranty on all its products. While rare, you can request warranty services if you find any of your parts are defective.

Better yet, you can also get an auto-refill for an efficient filter replacement. Upon purchasing the air purifier, you’ll also get a 60-day satisfaction guarantee (minus the shipping fee).

Molekule Air Purifier Design and Size

One of the most notable features of the Molekule Air is its sleek design. It’s crafted from machined aluminum and comes in a silver coating that blends in well with other appliances and furniture. No other air purifier on the market has such a design, and it’s one of the many features that help it stand out from the competition

The dimensions and weight of the Molekule Air are as follows:

  • Dimensions: 23″ (H) x 8.25″ (W) x 8.25″ (D)
  • Weight: 18 pounds
