Review on 🌬️ Mitcent Bladeless Air Purifier Fan - Efficiently Capture 99.95% of Smoke, Dust, Pollen, and Dander - 40 Inch Black by Dana Rodriguez

This is a very good bladeless fan with air purification capabilities and 32 inch height is just what I need. The room was remarkably comfortable on 97 degree days when direct sunlight is at its strongest during the day and evening. My two criticisms are as follows: 1. No top vents, bladeless fan arch. If there were more ventilation holes at this point, the air would circulate even more efficiently and powerfully. Replacement filters appear to be brand specific and compared to other bladeless fans that use standard HEPA filters available at your local hardware store, they are noticeably more expensive compared to Revain filters. If the manufacturer takes these two points of criticism into account, it is definitely a five-star product. UPDATE 8-10-21 Needs downgrading to 3 stars as when falling asleep the device doesn't work as it used to. Instead of reducing the noise level for a restful night's sleep, it now gets loud; almost as if I set the device to mode 7 or 8. Now I don't know if that is related to the filter or what, but that brings me to the second point for the star downgrade. The frequency filters need to be replaced at $18 each, plus they're not easy to buy when they're rarely available at Revain. If you look at the filter now, it might also need to be replaced after a month of use. It is unacceptable to change filters so often to keep the device working well without a constant source of supply and at a high price. The seller says to change the filters every 3-4 months, but one filter is not enough for a month! At the moment, Revain has no Micent filters to buy and no generic replacements, which creates another problem.
