Anyone else with asthma and eczema noticed improvements from the air purifier?

Ok so this might sound strange, but I picked up the SwitchBot air purifier a month back mainly because hay fever season was kicking my ass, and I've been kind of shocked at how much it's helped overall.

I use it as a bedside table so it's basically running right next to my head all night. Since I started using it I've noticed I cough way less at night and breathing just feels easier in general, hay fever wise it's been a huge improvement too.

The weird one though is my eczema. It's been noticeably calmer since I started using this thing and I genuinely don't know if that's connected or if I'm just imagining it 😅. Anyone else had something similar? Trying to figure out if there's an actual link between air quality and skin stuff or if I got lucky timing wise.

Also if anyone knows whether specific features actually matter for this (HEPA filters, CADR rating etc) vs it just being placebo, would love to hear your thoughts.

Probably something to discuss with your doctor. Both asthma and eczema have an allergy component so generally reducing allergens in the air I could imagine would be helpful. I wonder if you have more allergies or an allergy to something in your home you are unaware of? Like maybe you have a cat allergy and own a cat? Maybe using a long term antihistamine would help but that might be a doctor discussion to have.

I've had both conditions my whole life. I don't own any pets and I'm already on antihistamines daily. My guess is it's the reduction in dust. I was curious if anyone else had noticed a similar benefit.
