As an asthma and allergy sufferer, this air purifier really eased my symptoms

As somebody who deals with asthma and allergies on a daily basis, breathing clean air at home is a must. Even without these ailments, breathing purified air improves your health, deepens your sleep, and reduces how often you get sick.

I test products for a living, and from the four air purifiers I've tested for H&G, there's only one I keep in my own bedroom: the Molekule Air Mini+. It's an advanced purifier that has immeasurably improved my wellbeing at home. I now barely use my asthma inhaler and, in the summer, I don't have to worry about hayfever when I'm indoors – even with the windows open.

It's certainly one of the world's best air purifiers.

What makes the Molekule Air Mini+ so great

Here’s what I think makes the Molekule Air Mini+ worth your money this Black Friday if you’re looking for an appliance that will give you cleaner, healthier air at home.

In my review for the Molekule Air Mini+, one of the most incredible and unique features I discovered was Molekule's patented PECO filtration. Standard air purifiers will typically have a tight mesh filter (like a HEPA filter) to capture particles, and an activated carbon filter to deal with gases and odors.

But Molekule's Air Mini+ and the bigger, more expensive Molekule Air Pro utilize a third layer of filtration, known as PECO tech, that actively destroys pollutants at the molecular level. So rather than just filtering out these harmful particles from your air, it deactivates the contaminants, making everything even safer when re-released back into your indoor space.

From my four months of using the Molekule Air Mini+, and testing three other purifiers alongside it, I can confirm that its effects are among the best.

At its lowest setting it can run quietly in the background, often going unnoticed when I'm working or sleeping in the room. At its highest settings, it can rapidly remove smoke, viruses and other pollutants from the air, and you can see just how quickly it does the job on the Molekule app with detailed air quality data over time.

Before being available to consumers, Molekule had great success developing air purification systems for commercial spaces like hospitals. The Molekule Air Mini+ and the Molekule Air Pro are two of the only air purifiers that are FDA-approved as Class II medical devices thanks to their unique ability to destroy harmful matter.

This tech, naturally, comes at a price, as the Molekule Air Mini+ is usually priced at $360. Now that the price is down to just $209.99 for Black Friday, its lowest of all time, you can bring this market-leading air purifying technology into your home for a fraction of the usual cost.

Trust me, you won't get a better air purifier at that price.

If you're looking for more coverage (the Air Mini+ covers 250 square feet), the Air Pro can cover up to 1,000 square feet. It's also on offer for Black Friday with a whopping $420 discount.
