I’ve never owned an air purifier but suffer from seasonal allergies and dust allergies so I was curious if this could help. I was surprised how big this was but it’s good because I can use it in my living and dining room area. I feel like it’s helped keep the air clean and free of allergens which means less sneezing in the house. The other reason I really like it is it helps clear the air after I cook. Usually I have to use candles or air freshener to mask smells but the air purifier helps to keep the indoor environment odor free. The volume while the unit is on isn’t too bad and I’ve gotten used to it. I don’t sleep in the room we use the purifier in so the sound it makes ends up being background noise. Overall a very good unit and I’m happy with all the benefits it provides.
