What is the #1 air purifier? ›

Our top pick for most homes, the Levoit Core 300S Smart True HEPA Air Purifier, can be considered rare in a sense because it has smart features—including an app that gives you access to timers, air quality readouts, and air quality trends—but costs closer to the average.

Length of time to leave it on

This is why most manufacturers will recommend you to leave your air purifier running all day, especially if it comes equipped with an automatic setting.

HEPA (high efficiency particulate air [filter]) is a type of pleated mechanical air filter. This type of air filter can theoretically remove at least 99.97% of any airborne particles with a size of 0.3 microns (µm), which can include dust, pollen, mold, and bacteria.

ULPA filters trap more and smaller particulate matter than HEPA filters. ULPA filters are 99.999% effective at removing submicron particulate matter of 0.12-micron diameter or larger, while HEPA filters are 99.97% effective for eliminating particulate matter of 0.3-micron diameter or larger.

When it comes to cleaning the air in a single room in your home, a portable air purifier is sufficient. But if you want to improve the indoor air quality throughout your entire house, a whole house air filter or purification system can clean the air as it passes through your home's HVAC system.

Air purifiers can use a range of filters, including activated carbon filters, ionizers, and ultraviolet (UV) light. While these filters can be effective at removing some pollutants, they are not as efficient as HEPA filters when it comes to removing small particles like pollen, dust, and smoke.

Living room air purifiers should be a medium between the middle of the room and near seating areas. The middle of the room is the best spot for an air purifier to handle air pollution, because it both has access to the most particles and can have the biggest impact on moving air in the room.

Air Purifiers Should Be Placed on the Floor in Most Cases

Most airborne pollutants, including dust, pet dander, and pollen, tend to settle due to their weight, leading to increased pollution in lower indoor areas. So placing the air purifier lower helps capture these pollutants effectively.

Room air cleaners are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air. A standard room air cleaner, operating continuously, uses approximately 450 kWh per year in electricity. This is more than the energy used by some new refrigerators!

Headaches, sore throat, coughing, Asthma attacks, and difficulty breathing are a few of the symptoms that can be brought on by some air purifiers. Yes, that's right. Your air purifier may actually aggravate many of the health issues you hoped it would solve.

What to look out for when buying an air purifier? ›

HEPA filters may cause air to become too dry. Finally, some HEPA filters may produce ozone, which is an unhealthy gas that can irritate the lungs. If your home or certain office areas are frequented by individuals who suffer from allergies or respiratory problems, HEPA filters may prove to be of great value.

They are expected remove at least 99.97% of airborne particles 0.3 microns in diameter, while particles smaller or larger than 0.3 microns are removed with an even higher efficiency. The recommendation for routine HEPA filter replacement is every 10 years.

The short answer is yes, most air purifiers on the market are designed to remove large dust particles from the air. Many feature mechanical filtration, which is a method of capturing pollutants on filters. Either the particles are meant to stick to the filter or be trapped within the filter fibers.

In many cases, one air purifier is sufficient for a single room, as long as it's rated to cover the square footage of that room.

The reality is, air purifiers offer an effective option for helping remove particles from the air that circulates in your home. How effective depends on a number of factors, starting with the quality of the air purifier. A high-quality whole-home air purifier filters the air for your entire home.

3-IN-1 MODES: Choose between purified air, purified heat, or purified fan for pure comfort in every moment.

The CADR number tells you how quickly the air purifier removes 100% of a given pollutant — like smoke, dust or pollen — from a cubic foot of air per minute. The higher the rating, the larger the space an air purifier can clean or the more times per hour it can change the air.
