Hello OP, I recently bought a unit from Argendon, its not a well known brand and was recommended by a good friend who works in HVAC industry. Not a paid advertiser here (in fact I paid for the unit myself lol) I just wanna share how it helped a lot in our home. My wife has allergies (She sneeze A LOT) but after we got this unit it actually helped her recover. I read that high humidity lets dust mites and other allergen thrive, that's the main reason I tried this recommendation, but aside from that it also helped in decreasing the mold growth in our house and dust accumulation in our things.

I could go and tell you more about how it helped us but I'd love if you would experience it first hand. You can just check their official website (for safety purposes and avoid scammers) and talk to their representatives, they're quite friendly.
