Why is Coway Airmega AP-1512HH Mighty Our Top Choice?

In just half an hour, the Coway Airmega AP-1512HH Mighty impressively reduced dense smoke pollution in a New York City office by up to 99.6%, a performance on par with other leading models and consistently replicated across different testing environments. This machine has been tested to the limits, including having its filters run non-stop for two years — double the recommended duration — without showing any signs of faltering. It stands out for its affordability, both initially and over time, and its design is both sleek and practical, featuring quiet operation and a display light that can be turned off, making it a perfect fit for bedrooms or living areas.


What to Consider When Choosing an Air Purifier

Filter replacement costs: Regular maintenance is crucial for air purifiers. Pleated filters should be swapped out or cleaned if vacuum-friendly every six to 12 months, while activated carbon filters need changing every three months. As an indicator light on many models, we evaluate signals when it's time for a filter change or cleaning. Replacement filter prices vary significantly; in our evaluations of large air purifiers, they can range from $20 to over $200, with those designed to eliminate odors costing up to $50.

Clean Air Delivery Rate (CADR): The CADR, a measure provided by the Association of Home Appliance Manufacturers for tested air purifiers, indicates the amount of clean air produced at the highest speed in cubic feet per minute. Air purifiers with a CADR of 250 for dust, for example, can lower dust concentration as effectively as adding 250 cubic feet of clean air every minute. A higher CADR means the purifier works faster and more efficiently, especially true for models with HEPA filters. CADR ratings vary for smoke, dust, and pollen removal. Select a purifier with a high CADR for the pollutant you're most concerned about, like tobacco smoke in homes with smokers.

Energy efficiency: Because air purifiers are most effective when run continuously, consider the energy consumption. Models certified by Energy Star are 40% more efficient than non-certified ones.

Suitability for room size: The AHAM Verifide seal on an air purifier indicates its effectiveness for the recommended room size. However, it's wise to approach manufacturers' room size claims with caution, as our testing has shown that some purifiers do not perform well in their advertised room sizes. Our reviews provide suggested room-size ranges. For versatility, consider a model rated for large areas; they can also efficiently purify smaller spaces at lower, quieter speeds.

Noise level: The constant operation of air purifiers means their noise level is an important consideration. Ideally, they should be as quiet as possible. A noise level of around 50 decibels is comparable to a refrigerator's hum. Look for noise level information on product packaging or online listings, or consult our ratings for noise evaluations at different speeds.
