Starting with a baseline air quality index of moderate pollution as noted in EPA guidelines, we observed a significant improvement within just an hour of operation on the medium setting. Performance The Megawise purifier performed similarly to other models in this category. Its performance in a small room was satisfactory. We started with a steady 140 AQI and ran the air purifier on turbo for 10 minutes. After 10 minutes of running, the AQI registered at 83. After running the air purifier on turbo for 30 mins, the AQI has dropped to 52. After an hour AQI is at 40, and after 2 hours the AQI is at 15. Avg baseline AQI is around 2 or 3. The air purifier performance seemed to slow down after two hours. It cleaned the air at a similar rate to the Levoit Core Mini but the Megawise Desktop had to run on a higher fan speed and was much louder. Noise One of the standout features of the Megawise purifier is its quiet operation. On its lowest setting it is barely audible, but that is because the fan speed it so low that it didn’t even register on our meter. The lowest setting registered at 35 dB. At the medium setting it produced 45.5 dB of noise. On high it created 51.5 dB of noise. And the turbo setting produced 57 dB of noise – quite loud and potentially distracting. 35 dB on low fan setting 45.5 dB on medium fan 51.5 dB on high fan setting 56.9 dB on turbo fan Fan Speed On its lowest setting the Megawise Desktop Air Purifer is barely audible, but it is basically useless because the fan speed is so low it isn’t moving any air. In our tests, the low setting on the fan didn’t register on our meter. We tested this multiple times to be sure and with each test the lowest fan setting would never register a fan speed. The medium setting fan speed came in at 78.8 ft/min. The high fan setting registered at 177.3 ft/min and the turbo setting registered at 315.2 ft/min. This means that to effectively clean the air you should run it on high or turbo. The downside is that the fan is quite loud at these speeds. 0 ft/min on low fan setting 78.85 ft/min on medium 177.3 ft/min on high 315 ft/min on turbo fan Overview of Megawise Desktop Air Purifier Filters The effectiveness of the Megawise Desktop Air Purifier largely comes down to its True HEPA filter, capable of capturing particles as small as 0.3 microns. According to the American College of Allergy, Asthma & Immunology, this level of filtration is essential for removing common allergens, dust, and other pollutants from the air. The 3-step filtration combines a pre-filter with True HEPA and a Carbon filter to help clean the air and remove odors. Key Filter Features Easy Replacement: Filters are designed for easy replacement, ensuring optimal performance. Affordable Maintenance: Replacement filters are reasonably priced at $12.99, contributing to the purifier’s overall value. Total Lifetime Cost of Megawise Desktop Air Purifier Considering the purifier’s price at $49.99 and the cost of filter replacements at $12.99 every six months, then over five years, the total 5-year cost is remarkably affordable at $179.99. This makes the Megawise Desktop Air Purifier a good investment for those seeking to improve their indoor air quality without breaking the bank. How to Use the Megawise Desktop Air Purifier Using the Megawise purifier is straightforward. Simply plug it in, hit the top power button to adjust the fan’s speed and it begins purifying the air with its efficient filtration system. The optional night light can be turned on or off, depending on your preference. Final Verdict The Megawise Desktop Air Purifier is a good choice for anyone looking to improve the air quality in small spaces. It’s not as efficient or quiet as some of the other air purifiers in this category, but it is less expensive over 5 years.
