I’ve had asthma and allergies most of my life. Despite the best medical intervention I could find, I still have asthma flare ups that are disruptive. The ALEN was recommended to me by my allergy/asthma specialist who said, and I quote: “your system just responds to EVERY TRIGGER. This is the best air purifier to protect against that.” I have an ALEN in each room of my home and they’ve been life changers. I’ve been able to tolerate the air quality ups and downs in California during wildfire season with no problem-just changing my ALEN filters every three months. I’m married but I’m in love with Alen Air Purifiers. ❤️
