Molekule Air Purifier Review

Read our unbiased Molekule review and see if this unique home air cleaning system is for you.

Air purifiers are a great way to eliminate fine airborne particles and pollutants from your home. Machines with a true HEPA filter can remove 99.97″ of particulates that are 0.3 microns or larger.

Studies have shown that air purifiers remove airborne allergens and airborne dust particles to improve respiratory function in homeowners. In our review, we will break down the benefits of using a Molekule air purifier for your home to clean your air.

The Molekule air purifier works by cleaning the air in your home with a proprietary technology: PECO. PECO, also known as photoelectrochemical oxidation, removes pollutants from the air, including bacteria, viruses, mold, dust, pet dander, and even volatile organic compounds.

PECO can remove air particles that are 1000x smaller compared to HEPA filter air purifiers. This technology works at the molecular level, which is why the company coined its brand name “Molekule.”

A few air purifiers produce ozone as a byproduct; however, Molekule does not produce ozone and even can help lower harmful ozone levels.

Benefits of the Molekule Air Purifier

Molekule Air Purifier in Room

Why choose the Molekule air purifier? This machine outperforms other air purifiers on the market by using PECO technology to destroy tiny airborne particles and pollutants. Molekule also does not produce ozone.

Molekule comes in two sizes for homeowners: standard (up to 600 square feet) and mini (up to 250 square feet). The air purifier has an onboard sensor to demonstrate particle levels and comes with an auto-protect mode.

Molekule also makes an Air Pro RX model for healthcare professionals. Molekule destroys a large number of pollutants for cleaner, healthier air and better breathing.

If you have allergies or simply do not want to breathe in dust, toxins, and other pollutants, then we recommend the Molekule air purifier.

Design & Features of Molekule Air Purifiers

Sleek Design

The Molekule air purifier has a sleek design with a cylindrical shape and rounded edges. The light gray or crisp white create a clean, pleasant aesthetic that matches most home interiors from modern to industrial and rustic to classic.

Dual-Filtration Design

The dual-filtration design includes a pre-filter and a PECO-filter. Both filters remove pollutants from the air. By trapping larger particles first, the PECO filter can focus on destroying the smaller particles next with greater power.

Filters need to be replaced every six months on the Mini model. On the larger Molekule Air model, the pre-filter should be replaced every three months, and the PECO filter should be replaced every six months.

Size and Dimensions

The Molekule Air purifier weighs 18 lbs. And is 23″ high by 8.25″ wide. The Molekule Mini air purifier models weigh 7.3 lbs. and are 12” high by 8.26” wide.

App Control

Both Molekule air purifier models use the Molekule app, available on smartphones. This app allows multiple users to connect to the device and view the filter refill date, the fan speed, and operate purifier modes.

Operating Modes

There are several different operating modes with Molekule. One operating mode is the Auto-Protect Mode, which runs the fan speed and purifying system on its own. Dark Mode is a mode that shuts down your machine. Active mode runs your operating system at high speed, at all times.

Initial Clean Up

Molekule needs to perform an initial clean up when it is first set up in your home. Homeowners will input their room size and select a mode. Then, the machine will perform a calculation and begin an initial cleaning of the room. Typically, the initial clean up takes approximately twenty minutes to an hour and a half. The app will display the progress.

The Molekule air purifier is a state-of-the-art device. This air purifier eliminates dust, lint, bacteria, mold, viruses, and even volatile organic compounds (VOCs). It uses proprietary PECO technology to destroy airborne pollutants without ozone emissions. This technology has been developed by scientists over two decades to destroy pollutants at a molecular level.

This technology makes it possible for Molekule to eliminate contaminants much smaller than standard HEPA filters. As an allergy sufferer who is also sensitive to chemical smells, I appreciate how quickly Molekule can remove pollen, pet dander, and formaldehyde from the air.

This air purifier works by bringing in air from every direction with its 360-degree air intake feature. Then the air is brought through a pre-filter. From here, the air moves through the PECO filter and then exits the unit.

The Molekule air purifier can even destroy bacteria such as black mold by capturing it, oxidizing it, and then destroying it completely. These air purifiers are extremely quiet and are perfect for light sleepers who cannot handle significant amounts of fan noise. An onboard sensor displays the pollutant level and connects to a smartphone app.

This is the easiest app I’ve ever used for an air purifier. Activating “Protect” mode allows for greater airflow so air can be quickly purified when high levels of particulate matter are detected. I like that I can make adjustments to the app and my air purifier whether or not I’m at home.

The Molekule comes in a standard model size as well as a mini model. The standard model purifies air up to 600 square feet while the mini model purifiers air up to 250 square feet. Molekule offers a package deal to purchase both units at once.

Using both units has worked really well for me because I can put Mini units in the bedroom and the standard Air unit in the living room and kitchen. The company is FDA approved and also offers an Air Pro RX for medical use to healthcare facilities. It is the first medical-grade unit with PECO technology.

The standard model comes in a sleek light gray while the mini comes in a crisp, clean white. If you want a home with clean air, this is the perfect air purifier for you. More of a complete air purification system, the Molekule is the best air purifier for allergy and asthma sufferers.

Molekule Air Purifier Accessories and Parts

The Molekule air purifier comes with very few parts: the air purifier, the filters (two for air, one for Mini), and the attached handle. This makes installation a breeze for homeowners. The pre-filter for the Molekule air needs to be replaced every three months, and the PECO filter for the Air and Mini needs to be replaced every six months.

Light cleaning should include dusting the exterior and lightly running a damp cloth every one to two months. There is a limited two-year warranty on all parts and the unit itself.

Molekule Vs. Other Air Purifier Brands

Molekule vs. Dyson

Molekule and Dyson are both great air purifier brands. The most significant difference between the two companies is the type of filter: PECO vs. HEPA and activated carbon. Both purify air well, are durable, and can handle large rooms. The Dyson is higher rated at reducing pollutant particles, but Molekule can eliminate VOCs.

We recommend Dyson for allergy sufferers and Molekule for homeowners in cities with high numbers of VOCs.

Molekule vs. Airocide

Molekule and Airocide are both specialty air purifiers; however, Molekule outshines Airocide. Airocide uses NASA technology to clean air but focuses most on VOCs and very little on true filtration.

The Molekule air filter is better for cleaning out allergens in the air and is also much quieter in comparison to the Airocide.

Setup and Maintenance

When you first set up your Molekule air purifier, you will want to install both filters for the Air model and the single filter for the Mini model. Once the filters are installed, plug your unit into the wall.

From here, it’s important to start an initial cleanup. To do this, input the size of your room and select your preferred mode. Molekule will then begin an initial cleanup.

This process can take anywhere from twenty minutes to an hour and a half to complete. At the end of this process, Molekule will let you know how long it will typically take to maintain clean air in your room.

This should remain the same unless Molekule is moved to a new room.
