Pure Enrichment PureBaby On-the-Go Air Purifier - Portable Stroller Air Purifier & Adjustable Clamp for Car Seat, Crib, Bassinet & Playpen - True HEPA Filter Removes 99.97% of Allergens Around Baby

I purchased this when I was out with a terrible upper respiratory infection. My breathing improved greatly once this arrived. I still use it after cleaning to improve air quality in my smaller living space. Bigger filters get stinky faster and I feel I will get better results if the filter is changed more frequently. I love the mounting accessory, but I can hang it very easily from a lamp with just the normal attachment.

The handle doubles as a stand, which is nice. Unfortunately this air filter truly lacks power. The fan inside this thing barely pushes any air. On the highest setting, you can feel a slight breeze of air, but at that level it only lasts about 3hours before it runs out of battery. On the plus side it does work while plugged into USB-C! However, this thing will not charge or run if it's plugged into a USB-C port. You must use a USB-A to USB-C cord since it will only take 5V/1A. A standard USB-C charger will not charge or power this filter. If you can live with those gotchas, then this thing is pretty nice and sleek

I set this up next to my 3D printer, as my printer is in my work office where I sit daily. I am somewhat concerned about microplastics in the air, as I regularly use the 3D printer. This puts my mind at ease. It emits a small amount of noise, however the noise is overrun by the sounds from the bambu 3D printer, so it isn't noticeable. I only ever use the highest setting for filtering, as I turn the filter off when I'm not printing. I also really like the attachment accessories included with the device, as it allows me to clamp onto my monitor stand next to my printer. I don't have a particulate measurement tool so I cannot be certain of the PPM difference in the air, but it definitely removes the scent from stinky filaments while printing (ABS). Overall, I definitely recommend this product if you spend a significant amount of time next to your 3D printer!

This is a great portable air purifier and is exactly as the Product Page described. It seems to be made of High Quality Materials and has been working great for me. These are designed for SMALL AREAS like the inside of a small Truck Cab or Car with the windows closed. A closed baby stroller might be OK as well. None of these small HEPA filter fans are meant for total area filtration. Instead they are meant to filter air that is right next to you. With the filter in it barely holds a piece of tissue to the inlet holes, with the filter out it stays pretty good. But, with filter in or out there is a really decent amount air being blown out from this on it's highest lvl 3 setting. The one I got lasts a little over 4.5 hours on the lvl 3 highest fan speed. The red LED blinks while charging and then is solid RED once it's fully charged. Mine takes about 3 hours to charge from dead. This will run while charging also, so you could use a Power Bank to keep it running for longer periods of time while on the go. I'll be using this inside my car mainly. It fits well in my drink holder right next to me. I'm very happy with it and do recommend it.

I have to admit, I don't actually have a baby; I got this personal air purifier because I have one by the same brand that I really like, and I wondered if this one would be even more quiet. It turns out that it wasn't; but the other purifier was quite quiet to begin with, so that's not an issue. As far as I can tell, this purifier is identical to the purifier I already had from this company, except for the logo and the included stroller clamp. The other purifier is wonderful, so I'm happy to have this one as well. A small air purifier doesn't remove as many particles from the surrounding air as a bigger purifier, of course, but they can be used on planes, or placed on a table - or, if you actually have a baby, attached to a stroller. My previous purifier has lasted a long time, and I've been able to purchase replacement filters. I'm guessing this one will be of similar excellent quality overall.
