The Alen BreatheSmart Classic’s big draw is its amazing room coverage of 1,100 square feet. This is the best air purifier for large or open-plan rooms and it also comes with a choice of filter, so you can customize its functionality to best suit your needs. The BreatheSmart’s auto mode makes cleaning a breeze, adjusting its output to best manage the air quality it has detected.

 Alen BreatheSmart Classic: What you need to know

A high-end air purifier with the price to match, the Alen BreatheSmart Classic isn’t for anyone looking for a simple budget air purifier. But if you are looking for a powerful air cleaning machine for large areas and are happy to pay that bit more for it, keep reading. 

With a choice of 4 HEPA filters, each customized for different needs, an ionizer for deep cleaning and an activated carbon filter to capture bad odors, the BreatheSmart has great deep cleaning capabilities.

Many air purifiers are just functional and a bit ugly, but the great design of the BreatheSmart means it won’t look like an eyesore in your home.

Alen BreatheSmart Classic: Features

Most air purifiers come with one HEPA filter, but with the BreatheSmart you can choose from four, each designed for specific needs. All come with a pre-filter and activated carbon filter built-in.

Those that suffer from allergies related to pollen, dander, pet hair, dust or dust mites will find the HEPA Pure filter to be a great option and is actually considered a base filter layer included in most filter options. The HEPA Silver is the most well-rounded filter with four layers of protection, providing you with cleaner and fresher air. It’s a good choice for anyone particularly sensitive to dust, mold, mildew, bacteria, or light odors. 

Alen BreatheSmart specs

If you find volatile organic compounds (VOCs) such as air fresheners, bleach, furniture polish or hairspray irritate your breathing, it would be worth opting for the HEPA Fresh Plus. Great for smokers too, this filter has three layers for dealing with odors and irritants. Some rooms are prone to be a bit smellier than others. Kitchens can have lingering cooking odors, pets can stop homes smelling their freshest, while nurseries and teenagers’ rooms can have their own distinctive scent. The HEPA Odorcell filter will help combat all these, keeping your home smelling fresh.

The BreatheSmart’s infrared sensor detects particles in the air, adjusting settings accordingly when in auto mode. The On/Off ring changes colors to reflect the air quality, red for high levels of pollutants, orange for moderate levels and blue for clean air. This means you can see at a glance how well the BreatheSmart is purifying your air. The BreatheSmart is in about the same price bracket as the Dyson Pure Cool, but doesn’t have the in-depth feedback the Pure Cool can provide within the Dyson app.

Alen BreatheSmart Classic: User Reviews

Online reviews for the Alen BreatheSmart Classic average at around 4.5 out of 5. They praise its accurate Smart Sensor and reporting, saying they can see the air quality light change based on their activities. 

Those who have placed the purifier in large rooms and apartments have reported reductions in the amount of dust on their furniture and that their allergy symptoms have lessened since using the BreatheSmart.

It does a great job of capturing bad odors and smoke too. One reviewer noted that after six months her filter had turned orange and smelled heavily of cigarettes, while her home had been kept smelling fresh.

Should you buy the Alen BreatheSmart Classic?

It’s an expensive machine for sure, but if you’re looking for a purifier that specialises in large spaces, you’ll struggle to find something that performs this well and has this many features. The Smart Sensor is one of the major plus points for this purifier and its feedback system allows you to monitor what activities cause poor air quality to spike, while auto mode makes cleaning a breeze. 

User feedback is strongly positive whether the purifier was bought to combat bad odors or to help alleviate allergy symptoms, so it’s a good all-rounder too.
