The best air purifiers for 2020

Dust particles, pet dander, and other allergens can build up in the air you breathe. These particles can become a problem if you have allergies, suffer from asthma, or have young children.

You can take steps to improve the quality of your indoor air, starting by using an air purifier. These devices work by filtering the air and catching pollutants, allergens, and other particles. Running an air purifier in your home can significantly improve the quality of your indoor air.

Our list of the best air purifiers for 2020 include options with HEPA or PECO filters. We’ve included a variety of price ranges, so people who want an air filter can find one that fits their budget.

Honeywell 50250-S True HEPA Air Purifier

The best

hepa-1

The Honeywell 50250-S True HEPA is one of the best purification units on the market, namely because its glass fiber HEPA filter captures particles as small as 0.3 microns. To put that number in perspective, an average human hair is about 80 microns. Needless to say, this unit is more than capable of filtering pollen, dust, pet dander, and even smoke particulates.

A carbon-activated pre-filter also captures larger contaminants and works to eliminate common household odors. Unlike other units, this model uses a primary HEPA that can be vacuumed, thus allowing you to extend the lifetime of the filter.

As with any air purifier, one of the key things to consider is the maximum square footage the unit can adequately filter. Honeywell’s modest offering is designed for rooms up to 390 square feet in size. That is more than enough power to sufficiently treat the air in most rooms around your home.

The does feature a rather lackluster design — not to mention a bulky exterior. Even if the unit might not necessarily complement the feng shui of your living space, it’s more than capable of removing the fung-us in your home. (Pun totally intended.)

Alen Breathesmart 45i HEPA Air Purifier

The best for sleep

Air purifiers serve an important role in the home, but most of them are just not great for sleeping. The level of sound involved in pulling harmful particles out of the air can be detrimental to your sleep habits, even though clean air is arguably most important at night. The Alen BreatheSmart 45i HEPA Air Purifier offers a solution, however. The unit is tuned to produce only pink noise and promises to help you sleep up to 25% better than before. You can also activate “Night Mode” with a single tap to disable the lights on the unit.

Like other models of Alen units, the BreatheSmart 45i is incredibly customizable with 11 different color options to help it match your home’s style and color. The customization doesn’t stop at the outside, either. You can choose four different filters for the unit. All of the filter choices are effective, but some excel at certain areas over others. For instance, the HEPA Silver is better at removing mold and bacteria, while the HEPA Odorcell and Smoke filters are better at getting rid of unpleasant odors.

The BreatheSmart 45i automatically adjusts its energy usage depending on your air quality. When the sensors detect a low level of particles, the unit runs at a lower power to reduce noise and energy consumption, but higher power modes kick in when levels of airborne particles are high. An LED around the power button indicates the current air quality: blue for great, green for good, orange for not-so-great, and red for bad.

The Alen BreatheSmart 45i is recommended for 800 square feet at max speed, and 250 square feet on low speed. While it has a hefty price tag, this air purifier’s slim profile and multiple color options make it a great choice for the design-savvy consumer — and the efficient operation will keep you breathing easy all through the night.

The best for pet owners

It grabs tiny particles (it captures particles as small as 0.3 microns) and can make a real difference in the way you breathe. That pet dander that stuffs up your nose gets trapped in the filter, and you breathe clean and virtually allergen-free air. This machine doesn’t just clean your air free of tiny allergens though.

Holmes Small Room 3-Speed HEPA Air Purifier

The best budget option

Holmes Small Room 3-Speed HEPA Air Purifier is ideal for individuals seeking a basic and affordable air purifier. It’s perfect for your bedroom, office, or places with limited space. For convenience, this unit can also be situated vertically or horizontally without sacrificing performance.

Holmes’ unit can filter airborne particles as small as 2 microns. It has three different speeds so you can set it higher or lower as needed. Plus, it has an optional ionizer.  As with any budget option, however, this unit has its drawbacks. The Holmes Small Room model is only rated for rooms up to 100 square feet in size, and while 2 microns is fairly solid when it comes to household filtration, asthmatic individuals or people with other respiratory problems will certainly prefer a higher caliber purifier.

Rabbit Air Ultra Quiet HEPA Air Purifier

The most energy-efficient

The Rabbit Air Ultra Quiet air purifier is able to deliver Energy Star-rated performance by utilizing six different purification stages thanks to the implementation of the BioGS HEPA filtration. These stages include a negative ion generator, charcoal-based activated carbon filter, customized filter, BioGS HEPA filter, medium, and pre-filter.

The six-filter system minimizes airborne bacteria, pet dander, and dust, all common household contaminants whose absence means a fresher environment and cleaner air thanks to energy-efficient filtration.

The smallest particles remain in the filter system while larger particles stay in previous filters, maintaining proper airflow and reducing motor energy. The motor and filter work for up to two years with standard 12-hour per day usage. A built-in light sensor allows the Rabbit Air Purifier to transition automatically to sleep mode when the room is dark.
