The main claim to the manufacturer is hellish noise. The same Breeeth! Real (FSH-1000) is just quiet compared to this. There were 2 fans Zaward ZDAA12025S12MA01 with a nameplate performance of 103.26 CFM and noise of 39dB(A), respectively, together they give ~200 CFM (350 m3/h) and 42-43dB(A). Their noise is quite vile and even at half power is very annoying. I heard it even from the next room. Therefore, I decided to change them for now to a pair of NOISEBLOCKER Multiframe S-Series M12-2, (512022 CFM, 16 dB) pulled out of the system unit. He opened the case and went a little crazy - cable management - no, they didn't hear it. Now the plans are to pick up a more productive, but quiet fan, carefully deal with the cable management and remove the buttons for turning off the backlight and the electrostatic precipitator, because. my house is already quite clean (the air supply with filtration works)
