Review on Alen 75i Air Purifier - Powerful and Silent Air Flow for Extra-Large Rooms up to 1300 SqFt - Effective Allergen, Dust, Mold, Pet Odor, and Smoke Cleaner with Extended Filter Lifespan by Julie Lee

I have a couple of small Levoit air purifiers at home. A few days before Prime Day, I saw an offer on another cheaper brand. Well, that got me researching air purifiers. Alen 75i was definitely at the top of the list. I made my first choice based on the long warranty, incredible power efficiency, and great coverage. Who can argue with 45W of max power to clean 1300 square feet? I'm not too guilty of being on the device 24 hours a day, 7 days a week. Let me thank the previous reviewer who recommended the GoSund fork. Now I can monitor the 2.5ppm level and control all of Alen's functions from my iPad. Luckily for me or sadly, the Alen I bought was on sale on Prime Day for $150. So I bought a second one, wanted to return the first one as it hasn't even arrived yet. Long story short, I kept both. I look forward to this winter when the house is smoke free with a stove and a wood stove. It's definitely a big purchase, but I have no regrets. Surprisingly quiet. One thing for the folks at Alen is to get an online subscription filtering service and stock it. Many Thanks.
