Review Content Everyone should have one just in time for my long flight. Nothing better than clean air I like how small and light weight it is Pefect for new grandbaby travel. Our new grandson will fly from Denver to Oregon in February and we wanted to protect the little guy from on-flight germs. Everyone should have one Great for meetings as well as airplanes Great protection for your air space! Traveling on planes is always dicey when it comes to breathing recycled air due to germs, and the risk or potential for contracting airborne illnesses. Travel and touring can be even more problematic for people who are elderly or fighting health issues such as leukemia that make them more vulnerable to germs. This little device is soundless and provides a "clean" space about 3 ft. in diameter to protect travelers from germs, colds, etc., in crowds and during air travel. It works amazingly well, for long duration, is compact, lightweight, and is a must for avoiding airborne contaminants in closed breathing environments. EASY TO WEAR & EASY TO USE I purchased this small, easy to use, personal air purifier to wear when I fly. It is very simple to use and will help to protect me from catching any illnesses that are airborne within the confines of the recirculated air on-board an airplane. Since my silly immune system is not up to par, this wonderfully small product is now a must for me when I travel via plane. Great idea Great for meetings as well as airplanes Kepp baby healthy while fying. We purchased the personal air purifier for our 12 week old grandson to wear when he flies to Oregon with Mom and Dad to visit Grammy and Grandpa. Cant be too careful with that sweet boys health. Travel Safely Use this product while traveling to protect against infection from airborne illness in crowded public transportation : planes, buses, metros. It is also helpful at stadiums, restruants or other high risk settings. Im allergic to cigarette smoke, so if I go to a baseball game, the stadium is fine but just outside the exit Ill have to pass a gauntlet of smokers who cant light up fast enough. This is a device which acts as my personal "force field" against the smoke and reduces exposure. I would buy this product again I used this during business travel, specially going on longer flights over 4-5 hours. In my last trip the individual beside me had a cold and i certainly know i avoided getting it due to this product. quiet and compact We use this for travel in confined spaces (planes, cars etc), in particular for a family member who has a weakened immune system from chemo therapy. Its still too soon to say that it is a fail proof device, but it has worked for us thus far. Will always fly with me Bought this for a very long trip end of August, but did try it out on a short flight last week and it worked just fine. Will have another test while flying and touring in June. I plan to buy another for my son to wear when we are on a really long flight. Vacations are expensive, you need all the protection you can get to stay healthy. So far so good. Personal Air Purifier My husband has asthma and this works great for him when he is on a plane for 15 hours. He uses it every time he travels and never comes home sick. It also works great for me when I travel with him. GREAT ITEM! MY LUNGS THANK ME. I wear it around my my home, when I go outside and at the office. I love this product. Recommended it to my sister who suffers from algeries. She purchased one also. Lots. Personal air. Purifier I used it on the airplane to and from Australia. The battery case opened and spilled Batteries out. I had taken extras with me. Have not used the product yet Have not used the product yet. My husband is flying this week end and will be using it at that time. I could do a better review after Oct. 4.
