Molekule Air Purifier Review

Allergy season can be annoying for some people, and downright deadly for others.

It is a good idea to find ways to keep allergens in your home under control. One of the best ways to do that is by using a quality air purifier.

Our pick for the best air purifier for allergies is the Molekule Air Purifier. But this air purifier is effective at dealing with far more than allergens. It can remove dust, pet dander, mold, and various other particles from the air that you breathe in your home.

All in the Family

Molekule is a family-owned startup that began manufacturing their product for public use in 2016. But, the science backing this machine is at least 20 years old.

As the story goes, Dilip Goswami suffered from nasal allergies. His father, Dr. Yogi Goswami, was a prominent scientist who worked on solar energy. Dr. Goswami decided to do something to help his son find relief from his allergies.

After numerous attempts, as well as significant research and scientific patents, the Molekule air purifier was born. The company was formed in 2014, headed by Dilip and his sister Jaya, and now employs about 22 people.  

Nanotechnology Filtration

The current industry standard for filtration is the high-efficiency particulate air, or HEPA filter. These filters are very effective at removing particles that are 0.3 microns or larger in size. For comparison, the average size of a human hair is about 50 microns, and the unaided human eye can’t really see anything smaller than 40 microns. So these filters can get at very small particulates in the air.

But there are still problems. For one, there are obviously smaller items in the air than 0.3 microns. Second, filters of any type inevitably gather build up, which can become a breeding ground for things like mold.

What makes the Molekule air purifier unique is the way in which it not only collects smaller items, but also how it breaks down airborne particulates that are much smaller than 0.3 microns.

Molekule uses a light-activated nanotechnology which literally breaks down allergens, mold, pet dander, dust, and even viruses at a molecular level. Here’s how it works:

After air passes through the pre-filter, which removes larger particulates, it enters into the photo electrochemical oxidation (PECO) filter, which is the unique technology forming the basis for this machine.

In this filter, particles bond with nanoparticles which, when activated by light, cause a chemical reaction to break down the pollutant at a molecular level. The machine is capable of breaking down particulates that are 1,000 times smaller than HEPA filters are capable of filtering.

Once this process happens, the particles become harmless and fall to the bottom of the filter.

It is recommended that you replace the PECO filter once every six months or so, and the prefilter once every three months. These filters aren’t cheap to replace, but you can join a subscription program for about $130 annually.  

Coverage and Noise

The Molekule is a relatively big machine, and weighs about 18 pounds. Because it uses a 360 degree air intake system, you can’t really place it in a corner. Luckily, it’s actually pretty stylish.

The machine is recommended for rooms as large as 600 square feet, and it features three different speeds. At the highest speed (turbo), it can get a bit loud. However, it is very quiet on either the medium or lowest modes.

Additional Features

This machine comes with a leather handle at the top, making it relatively easy to move. Molekule also has an app that enables you to set the various controls from your smartphone.

You can program the device for room size and then set it to auto so that it will run periodically at a given speed. The LED light on the panel also has a “nightlight” mode so that it won’t be annoying while you sleep.

This device is also energy efficient, though not Energy Star rated.


Molekule offers one of the most remarkable air purifier options on the market. It is a machine that really brings science and style together so that form and function complement one another. At $799, this machine is definitely an investment, and with the replacement filters coming in at around $130 annually, the price tag may scare some folks away.

However, with its effectiveness – which has been independently verified – it is difficult to argue that there is a better use of your money, especially if you suffer from allergies.
