We live on a ranch so there’s a lot of allergens in the air. I opened my Levoit  Core 200S Smart True HEPA Air Purifier to use in my fairly big living room in hopes it would help. It definitely did! It was easy to set up, you just turn it over, unscrew the bottom and remove the plastic on the filter, pop it back in and screw it back on, plug it on and it’s ready to go. The lights on the control panel are nice and bright and it gives you the option to turn them off which I do at night, it also has a sleep mode which is awesome. It makes it very quiet. You can put the purifier on a timer in case you don’t want it running all night. The air that comes out of the purifier is nice and cool and comes out at a good flow. You down load an app and can control it from your phone which is really nice. I would definitely recommend this Levity Core 200S Smart True HEPA Air Purifier
