What is the Most Highly Recommended Air Purifier?

In the world of air purifiers, there are many options to choose from. From the Levoit 400S to the Dyson Purifier Cool, each air purifier has its own unique features and capabilities. But which one is the most highly recommended? The Levoit 400S is a Good Housekeeping seal holder, thanks to its combination of value, performance and intelligent design. It has a three-stage filtration system, including a true HEPA filter, that captures even the smallest airborne contaminants in rooms up to approximately 400 square feet.

It also has a built-in precision laser sensor that accurately monitors particles in the room and automatically adjusts fan speeds as needed. Plus, it's incredibly quiet, working at only 24 dB, making it perfect for bedrooms. The Levoit 400S also has intelligent capabilities, including the Levoit app, which allows you to monitor air quality in real time, view filter life, and set schedules. Our staff evaluator has been using it for several months and says that the light hum is quite quiet at night.

The Coway-AP-1512HH air cleaner also benefits from a built-in particle sensor. This means you can get an idea of the air quality in your home with the color coding system on top of the device. It will show a blue light when the air is clean, purple to indicate pollution and red for high pollution. It also has sensors that can adjust fan speed to keep the air clean, so you don't have to alter settings.

Plus, it has an Eco Mode that turns off the air purifier when air pollution is low, saving energy and money. The Dyson Purifier Cool is one of the most elegant air purifiers on the market. Its unusual design makes it a talking point in any room, while simple but cool extras like a magnetic remote control take it one step ahead of an average air purifier. Our home tests found that it removed 98% of particles smaller than 0.3 microns, 72% of particles smaller than 2.5 microns, and 73% of particles smaller than 10 microns at a level 6 setting.

At a level 10 setting, it captured 95% of particles smaller than 0.3 microns, 96% of particles smaller than 2.5 microns, and nearly 100% of particles smaller than 10 microns. The Dyson Purifier Cool's high price tag may be too expensive for some budgets, but its sleek design and smart connected functionality are impressive. Finally, our home tests found that the Blue Pure 221 was consistently better than all the other air purifiers we tested. Despite its lack of Smart technology, it outperformed purifiers at almost double the price.

In a Level 2 setting, we found that it absorbed 99.7% of particles smaller than 0.3 microns, 99.5% of particles smaller than 2.5 microns, and 100% of particles smaller than 10 microns. In a Level 3 setting, we found that it absorbed 99.9% of particles smaller than 0.3 microns, 99.6% of particles smaller than 2.5 microns, and 100% of particles smaller than 10 microns. When it comes to choosing an air purifier for your home or office space, all three options are great choices depending on your needs and budget. The Levoit 400S is perfect for those looking for an effective air purifier with great performance but doesn't break the budget; The Coway-AP-1512HH is ideal for small room spaces up to 361 square feet; And the Dyson Purifier Cool is perfect for those looking for an elegant air purifier with smart connected features.
