Hand Tree is one of gadget series of Tree concept, it’s a proposed solution to deal with our polluted air. This gadget is your personal air purifier that you can literally carry anywhere with you by wearing it on your wrist. The rapid growth and development of cities cause the same level of rapid pollution in our planet, some people have difficulty breathing because of that. This designer sees the necessary action to develop a personal device which is light and compact to clean the air around us. It was based on the same principle as plants that absorb polluted air and emit purified one to create their own atmosphere. Imagine if everyone in this planet wore that device, we would all breathe easier. Designer : Alexandr Kostin This concept is just one part of other appealing wearable accessories; this technology can be incorporated in a series of pendants, belts, bracelets, and many more. There are 2 modes in this system: automatic and manual. When user switches to automatic mode, Hand Tree would constantly monitor its environment and it will automatically activate the purification process once it detects high level of polluted air.

Hand Tree kit comes with charging kit, user can charge the battery of this device wirelessly thanks to the technology of Qi. The body material is made from eco plastic Biograde and meets all federal health standards. The color changes in the body indicates the pollution level, the battery power is displayed on the screen and menu. User can configure how this device works from the menu, simple and easy to understand.The Wein 150MM Personal Air Purifier clears the air in your personal space of up to 90% of all airborne biological particles, like germs, pollutants, allergens and molds. This ultra-lightweight wearable air purifier is no bigger than a small pager, and operates using a lithium battery. The Wein Personal Air Purifier with breakaway strap for safety is a must have for air travel, movie theaters, waiting rooms, or any confined area because it propels clean, healthy air into your breathing zone. Includes breakaway strap and one (1) lithium battery. Note:  If you are an asthmatic, please consult your physician before ordering the Wein 150MM.

Wein air purifiers are subject to Minimum Advertised Pricing (MAP). Lightweight, wearable ionizer purifies air in your personal space Kills most airborne microorganisms like viruses and bacteria Renders allergens from mold, pollen and dust mites harmless Oxidizes many dangerous chemical contaminants Eliminates odors in the air Ozonates with only a very faint, clean smelling, external ozone fragrance Silent, fanless operation with no filters to change Lithium CR123 one battery included Approved for air travel Research has shown that mold is the primary cause of Chronic Sinusitis. This Personal Ionizer is part of a Mold-Reduction Protocol developed by Dr. Donald P. Dennis, M.D. Wein 150MM Product Notes and Tech Data: A highly advanced form of air purification, the Wein Personal Air Purifier has a unique corona discharge technology that is a truly revolutionary breakthrough. This wearable air purifier emulates natural ozone to create the quality of air that is realized just after a thunderstorm, when air is at its freshest and cleanest.

As during a thunderstorm, a corona discharge of negative, high-energy ions is passed through the air, cleaning it extremely well.the best hepa air purifiers The Wein Personal Air Purifier utilizes a proprietary technology – the negative corona discharge design and a neutral grid configuration project a powerful stream of over 70 trillion ions per second internally.whole house hepa air cleaner filtration system Corona discharge technology has been used by the military and in industry for years. can an air purifier help with allergiesHowever, the technology has only recently been miniaturized, allowing it to be used on a personal, portable level. The Wein Personal Air Purifier is the first and only personal air purifier to utilize this advanced technology.

The destruction of airborne contaminants is self contained within the Wein 150MM unit. Purified air is ejected from the Wein personal air purifier unit at a velocity that approximates the same airflow as normal human breathing. As with all of Wein's corona discharge ionic air purifiers, ozone emissions are very low and safe for anyone. The Wein 150MM unit comes complete with lithium battery. Turn on unit by sliding the switch located on the side upward. You will hear a soft swoosh as the ionic discharge begins. Place the strap with unit attached around your neck. Alternatively, clasp unit to shirt pocket with top metal grill facing upward. Unit should be 6 to 8 inches from nose. You will see a neon indicator, ion monitor light when the switch is activated and a purified cold breeze begins to waft up toward your face when you inhale. If neon light is not lit (or there is no breeze), it is time to change the battery. This is not a fan or mechanical blower.

Airflow has been limited so that sensitive mucus membranes are not affected. If operating in a polluted area and you hear a hissing sound, blow gently into the top of the grill to dislodge dust buildup. For heavy pollution, bend head forward closer to unit to draw in more ionized air. Do not immerse unit in liquids or allow fluids to enter unit. Do not open or attempt to repair unit. Slide side battery access door all the way off, exposing the used battery. Put thumb against bottom of exposed battery and press inward and swing used battery out at the top. Replace with new battery by inserting positive end first and swinging negative end onto bottom metal contact. Using the grooved rails, slide battery access door back on. Rated 4.00 out of 5 based on 1 review.If you live in a city, the air you breathe probably isn't doing you any favors. Most American urban areas maintain an Air Quality Index (AQI) score of under 100, meaning low-to-moderate risk of airborne pollutants.

But prolonged exposure even to this decently clean air is still linked to long-term health problems. If you live in an industrial center like Beijing or New Delhi, the risk is far worse.A new Kickstarter project, which has been gaining support for a few weeks now, might have a solution. The device, called Wynd, is a small cylinder that looks a lot like Amazon Echo -- only it sucks in particulate matter and expels 8 liters of purified air per second, creating a personal clean-breathing bubble for the user. Although it will sell for $189 (about £146, AU$252) and ship worldwide when we hit the expected release date in November, Wynd is currently available for preorder on Kickstarter for $139 (about £108, AU$186). Besides air purification, Wynd has some tricks up its sleeve. First off, a detachable sensor on the bottom of the device can moonlight as a standalone wearable, constantly assessing the air you breathe. You can purchase this wearable sensor by itself for $69 (about £53, AU$92), but the developers are clear that the real magic of Wynd isn't its sensing tech, but its cleaning tech.

Wynd was assembled by engineers with backgrounds in jet turbine design, and it shows. The form of the device is elegant, and its function impressive. Air is sucked into the sides of the cylinder, and blown out the top to create a sort of bubble of clean air. The fan is designed to keep the clean air from dissipating. Of course, we'll have to wait and find out how well it actually works -- but the idea is still cool.Although the device is easily branded as an individualized air purifier, Wynd has the possibility of doing much more. The Bluetooth-connected app includes software that tells you about the air Wynd cleans, like its AQI and the size of its particulate matter. According to Wynd's developers, this data could be a valuable crowdsourcing tool for the future, allowing users to see which public spaces are cleaner and which more polluted. Plus, by tracking the size of the particles, Wynd should be able to code the data on a basic level, indicating more and less dangerous types of pollution (such as finer material resulting from combustion, versus larger matter like dust).
