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 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.
Theis 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.
