Review on MORENTO Air Purifiers for Home Smokers: 99.97% Effectiveness Guaranteed by Brenda Wang

You'd think they would tell you what the BLINKING red light means: A) Change the flip-up filter (I changed mine too early. Never mind. But they are expensive )B) RESET the filter timer BY HOLDING THE POWER BUTTON PRESSED FOR AT LEAST 3 SECONDS all for MORENTO but found info for another manufacturer (see INSTRUCTIONS above) Very frustrating ArghUPDATE --- all is good I like the Morento H13 air purifier now that the red flashing light has been fixed Morento is quiet and efficient works well THANK YOU MORENTO
