Delivered on time and easy to understand. I like the child lock. I had an another smaller Levoit but needed to handle a bigger potentially risky job. Ordered two units and delivery was quick. Wanted to start cleaning quickly JIC molds, spores and more was floating in the air. I was surprised how quick it reduced the smell of fouling in a large dirty area that had challenged our N-94. I hope I will be able to clean and sanitize the unit after the job and replace the filter for the maintenance use. I will see if it prevents illness and handles smells as time goes on. It looks easy to clean. Black color recedes visibly enough as unit is large. It cools the area nearby so I’ve cooled off sleeping area on hotter nights foregoing a fan or AC. Very quiet unit even set on high. I’m sleeping great snd I’ve used it as whitish noise as well. I think it’s a good buy getting 2 and will use our existing smaller one in bedroom

This is my very first Puroair Air Purifier and I am extremely thrilled how it has made my breathing better. The air in my bedroom feels so much cleaner and I don’t wake up with nasal congestion or coughing. This air purifier is supreme and I give it a 5 star. However, it should be 3.5 stars due to a glitch when ordering the “BUNDLE” (should come with an air purifier with 2 replacement air filters) for $199.00, but Amazon does not recognize this is a “bundle” order resulting in 2 separate delivery. It now only comes with 1 replacement air filter instead of 2 air filters. I immediately contacted Amazon customer service about this problem and the representative was able to send me the missing replacement air filter. I ordered 3 Puroair air purifier bundle and each time the same problem happened and I had to contact Amazon customer service. Customer service representative looked at my order and was able to complete my “bundle” order (1 air purifier and 2 replacement air filters). Price was reasonable, especially with the “bundle” promotion. The unit is easy to operate and you can adjust to the noise level which can be very quiet in low setting. I highly recommend this air purifier.

The newest addition to our "safe room" aka the bedroom... which isn't that big (maybe 350 sq ft). But when it comes to a safe recovery room, I'm gonna over-do stuff, because you can't put a price on your health. Best part, no WiFi, Bluetooth or "SMART" features... just clean air. I like that it has an air quality sensor and it adjusts the fan automatically based on air quality - which it gives you a visual indication of (red, yellow, green). I tested it out by smoking a clove cigarette and it went red pretty quickly. About 6 minutes after I snuffed the cig out, it was back to green again. I verified it with both my Temtop LKC-1000S+ (2nd gen) and my GQ AIR-760 meters and the built in sensor on the purifier seems to be pretty accurate! After laying down with it running for about 2 hours, the air in the room certainly just felt cleaner to me. Nice that it has a HEPA14 filter that takes care of particles down to 0.3 microns - about 700x smaller than a human hair. I've only had it for about 1/2 a day, but so far, I'm happy with it and it'll likely become a permanent addition to our recovery room! Replacement filters are about $50... but if it only needs replaced once a year, I'll be happy. It's also nice that you can put it against a wall if you turn it around with the back facing out. The company may be based in the USA - but the box clearly says Made In China. For that, I'm gonna take off one star. I would only take off 1/2 a star and give it a 4.5 but can't do that on Amazon. It was slightly disappointing as I thought I was getting a USA made product. Slightly deceptive.

I’m not one to write reviews but after setting this air purifier up in my room I was amazed. First 15 minutes the light on the unit turned green, cleaning the air in a 300 sq ft room very quickly. I went to sleep and woke up with a clear nose and a great restful sleep. First time in years. With no medication. The unit is super quiet and I have one in my living room as well. I can relate it drinking really pure spring water instead of tap water. It’s still water but you can tell the difference. I would highly recommend this product to anyone.

I’ve been using the Puroair 240 Air Purifier for a few weeks now, and I’m genuinely impressed with how well it performs. As someone who struggles with seasonal allergies and owns pets, clean air is a must—and this unit has made a noticeable difference. Within the first day, I noticed less dust settling on surfaces and my allergy symptoms started to ease. The HEPA filter captures everything from pollen to pet dander. Even on higher settings, it runs surprisingly quiet. On low, it’s barely noticeable—perfect for bedrooms or home offices. t doesn’t take up much space and blends in well with modern decor. Lightweight enough to move from room to room if needed.

We live in Arizona where it is hot and dusty. It arrived on time and was very easy to set up. We have this purifier in our large greatroom. It does a great job of filtering the air, automatically turning on a higher fan setting when it senses dust in the air. This especially happens when we open our sliding door. It's quiet and hardly noticeable. The air does smell fresher and surfaces are less dusty. We haven't had it long enough to attest to it's longevity.
