Aviair Travo Pur Personal Portable Air Purifier/Negative Ion Generator.Eliminating Germs, Dust, Viruses, Bacteria,Allergens,Mold,and Odors. Car Vent Mount Station and USB Cable Included (White)

I think it is helpful. My mom had allergy, her eyes was itchy, tearing and runny nose last year. After I bought this for her, her symptoms are in remission.

Great.

It seems to be working, but it could just be my imagination.The battery lasts very long after it is fully charged.

Very very poor product the charge only last 3 to 4 hours then when you turn it off and use it the next day you have to recharge it again.Most other portable air purifiers you can leave on for an entire week. In the process of trying to get a refund however you can only email them, there’s no one to talk to regarding a refund

This thing is awesome. I bought it for seasonal allergies, specifically constant sinus infections (can't smell, always have a headache, face needs constant massaging). I figured if this works for 50% of my allergies, than it's worth it.I'm here to tell you that it did just that!After wearing this, my sinus infections/symptoms went away. I've been on a happiness high for the last week. I call it a high and mean it's a dopamine high. I didn't feel bad which means it didn't even cross my mind about taking my medications. I *did* feel great this last week, so I didn't need my Zoloft because I didn't *have* depression.Forgetting my Zoloft having no allergy symptoms meant I didn't take my anti-histamines also (they're in the same bottle). No anti-histamine... and I am technically still very allergic... and the scratching started BAD.Lessons of the story:1) It works for airborne allergens (I wear it around my neck about 4 inches below my chin using the included strap, and I have velcro on the back to stick it to the wall above me when I sleep).2) It makes you less depressed (side effect of feeling better overall).3) It doesn't fix your immune system4) It can lead to temporary loss of rationality from the dopamine high your body is creating.5) It does mean that if you DID, then you will CONTINUE TO have other side effects from allergies.6) The batteries last a long time (at least 5 days on one charge).

Excellent design and durable, but it is expensive for retired fixed income holder!!!
