Best Indoor Air Purifier

Best Indoor Air Purifier – For many allergy sufferers, winter is a time of year to look forward to. As colder weather moves in, outdoor irritants like pollen and ragweed retreat enough to give anyone who is susceptible a short reprieve. But just because those particulates are not present doesn’t mean sufferers are in the clear.

As temperatures drop, people in homes across the country are turning on the heat and closing windows, which shuts off the best option for increasing ventilation and giving indoor pollutants an opportunity to escape. And these sometimes harmful particulates, such as dust and mold, are ever-present in our living spaces.



The Samsung Cube Stack is one of only four models that earns Excellent scores for particle removal at both the high- and low-speed settings. But it certainly comes at a price. The stack is two Samsung Cube models placed one on top of the other to produce a much stronger cleaning machine. To get the desired effect, you’ll need to purchase two units, making it the most expensive air purifier in our ratings.

It’s also not as quiet as the top-rated model, and its annual cost is medium for filters and energy use. Test engineers find the stack to be best suited for large rooms, and given that it weighs 49 pounds, it’s best to keep it stationary. An indicator light will flash when it’s time to change the filter, and its functions can be controlled by an app.

Pros & Cons

2.LEVOIT Air Purifiers

The Levoit LV-H132 Air Purifier doesn’t deliver on an air purifier’s basic premise—to sanitize the air of harmful pollutants. It earns Poor ratings for dust, pollen, and smoke removal on both high and low speeds, making it one of the worst-performing air purifiers that CR has tested.

The maker claims it will clean the air in rooms up to 129 square feet, but CR’s particle-reduction tests find that the machine just doesn’t cut it. Though it’s relatively quiet and has a fairly inexpensive annual operating cost, its ineffectiveness makes these qualities feel like moot points.

Pros & Cons

3.Molekule Air

The Molekule Air won followers through an aggressive social media campaign touting a patented PECO filter, which the maker claims will destroy airborne pollutants at the nanoscale level. CR didn’t test those claims, but in our tests for particle reduction, the machine wasn’t able to adequately clean the air in the room.

The Molekule Air earns a Poor score in our test for particle removal at low speed and receives a Fair rating at high speed. So while we can’t say whether the company’s proprietary PECO technology destroys gases, viruses, and mold, we can say with certainty that the appliance falls short in its ability to reduce airborne particle pollution.

4.Pure Enrichment Genuine

This is a case of “you get what you pay for.” The lowest-ranking air purifier in our ratings happens to carry the lowest retail price. Pure Enrichment claims the Pure Zone Mini 2-in-1 removes close to 98 percent of dust and smoke, but when put to the test, the unit fails to live up to that.

It earns a Poor rating for dust and smoke removal on both the lowest and highest settings. Conveniently, the Mini 2-in-1 is portable and rechargeable. That means it can be turned on in your car or on a plane, as demonstrated on the product’s website

Pros & Cons

5.RabbitAir MinusA2

The RabbitAir MinusA2 Ultra Quiet air purifier targets pollutants and odors and features a six-stage filtration system that includes a HEPA filter, activated charcoal carbon filter, and negative ions. It works in rooms up to 815 square feet.

You can mount it on your wall, and it can even feature a work of art and double as room decor. It can be customized for your needs to focus on the concerns in your home, such as germs, pet dander, toxins, and odor.

Pros & Cons

6.Alen 75i Air Purifier

With the recent addition of the Alen BreatheSmart 75i Pure to CR’s ratings, there’s a new reigning champ in the air purifier space. The 75i proves to be top-notch at capturing and removing dust and smoke while running at its highest and lowest levels, earning an Excellent score in both tests.

Holding a conversation or getting work done while the unit runs should be easy enough: The model receives a Good score for noise levels on high and low speeds. Another reason this model receives high marks?

Pros & Cons

7.Blueair Classic 605

Man, can this machine clear a room. It’s one of only four models that earn Excellent scores for particle removal at both the high- and low-speed settings.

The Blueair Classic 605 runs whisper-quiet at low speeds, but it’s noisy on high speed. It’ll clean the air quickly, but you won’t want to be in the room while it does, especially if you’re having a conversation or watching TV. Of course, you pay for all that performance.

Pros & Cons


Best Indoor Air Purifier – Without fresh air circulating through your home, air pollution indoors can reach concentrations five times higher than air pollution outdoors, according to the Environmental Protection Agency. But a good air purifier can reduce some of those pollutants and help you breathe easier.

“The best air purifiers we’ve tested are able to remove small particles from your air whether at high or low speed,” says Misha Kollontai, who oversees testing of air purifiers at Consumer Reports.
